Candida Vulvovaginitis

Candida is the second most common diagnosis associated with vaginal symptoms. It is found in 25 of asymptomatic women. Fungal infections account for 33 of all vaginal infections. B. Patients with diabetes mellitus or immunosuppressive conditions such as infection with the human immunodeficiency virus (HIV) are at increased risk for candidal vaginitis. Candidal vaginitis occurs in 25-70 of women after antibiotic therapy.

Treatment of candida vulvovaginitis

Most C. albicans isolates are susceptible to either clotrimazole or miconazole. An increasing number of nonalbicans Candida species are resistant to the OTC antifungal agents and require the use of prescription antifungal agents. Greater activity has been achieved using terconazole, butoconazole, tioconazole, ketoconazole, and fluconazole. 3. Ketoconazole, 200-mg oral tablets twice daily for 5 days, is effective in treating resistant and recurrent candidal infections. Effectiveness is believed to be a result of the elimination of the rectal reservoir of yeast.


Candidaemia, i.e. bloodstream infection by Candida species, is a significant clinical problem, with the attributable mortality estimated to be between 10 and 71 (Kibbler et al., 2003 Safdar et al., 2004 Zaoutis et al., 2005 Falagas et al., 2006 Vigouroux et al., 2006 Zaragoza & Peman, 2006). In recent years there was a gradual increase in the incidence of Candidaemia (Bassetti et al., 2006 Sandven et al., 2006 Sendid et al., 2006). The symptoms of Candidaemia generally resemble those found for bacterial sepsis, i.e. fever, and in babies includes respiratory distress (symptoms recently reviewed by Sims et al. (2005)). Although non-albicans Candida species are found to cause Candidaemia, C. albicans is responsible for the majority of infections (42-100 ), with some variation found in different patient groups (Schelenz & Gransden, 2003 Tortorano et al., 2004, 2006 Badiee et al., 2005 Cliff et al., 2005 Laupland et al., 2005 Bassetti et al., 2006 Fridkin et al., 2006 Pasqualotto et al.,...


Candida albicans is an opportunistic pathogen that rarely causes disease in healthy individuals, but becomes pathogenic when host defense systems become compromised or when the organism can accumulate in large numbers, such as during prolonged antibiotic therapy. CNS disease usually results from hematogenous dissemination and, less frequently, through direct invasion 24 . An extracranial focus of candidi-asis is present in over 70 of patients with documented meningitis. Approximately 50 of patients with systemic candidiasis develop one of the following forms of CNS involvement Candida produces a chronic, granulomatous meningitis, which, like cryptococcosis, can incite basal arachnoiditis with secondary cranial nerve dysfunction and or hydrocephalus. Candida meningitis often occurs as a late complication of debilitating illness. Clinically, the typical clinical signs of meningitis may be present but, not infrequently, patients may be so ill and obtunded that they do not manifest the...


Candidal hyphae penetrating the superficial layers (PAS D stain) Oral infections with candidal organisms are very common. The most frequent organism is Candida albicans, a yeast-like fungus 150 . It can cause acute and chronic white lesions and atrophic, red lesions. Candidal spores are present as commensal organisms in the mouths of as many as 70 of individuals. The infective phase of the organism is characterised by the presence of hyphae that can directly invade oral keratinocytes 31 . A wide variety of factors predispose to infection by candidal organisms, particularly depressed cellular immunity and inhibition of the normal oral flora by broad spectrum antibiotics. Fig. 3.8. Candidal hyphae penetrating the superficial layers (PAS D stain) Thrush, or acute hyperplastic candidosis, is seen most commonly in neonates whose immune systems are still developing and in debilitated patients at the extremes of life. It is also a feature of patients with xerostomia due to...

Oral Cavity and Oropharynx

The significance of Candida albicans as a possible aetiological factor of oral leukoplakia (OL) remains disputable 24, 303 , as does the role of HPV in oral carcinogenesis. The involvement of HPV in the initiation and progression of oral neoplasia is still a matter of debate. Different studies have generated conflicting results concerning the prevalence of HPV, ranging from 0 to 90 45, 345, 386 . The discrepancy observed may be related to the varying sensitivity of the methodologies applied for HPV detection and the epidemiologic factors of the patient groups examined. A recent study on 59 oral SCCs showed that the occasional findings of HPV DNA (8.4 ) may be the result of incidental HPV colonisation of the oral mucosa rather than viral infection. In the same study, HPV DNA was detected in 6.6 in the control group of healthy people who matched the subjects with oral SCCs in various clinical parameters. HPVs, therefore, probably play a limited role in the aetiopathogenesis of the...

And Oropharyngeal Leukoplakia Proliferative Verrucous Leukoplakia and Erythroplakia

Oral leukoplakia is a clinical diagnosis of exclusion. If any oral white patch can be diagnosed as some other condition, such as candidiasis, leukoedema, white sponge naevus, lichen planus, frictional keratosis, nicotine stomatitis, etc. then the lesion should not be considered a case of OL 263 . The white appearance of OL is most often related to an increase in the surface keratin layer. OL affects approximately 3 of white adults 46 . It is most frequently seen in middle-aged and older men with an increasing prevalence with age, reaching 8 in men over 70 years 48, 49 . However, recent studies reported a tendency towards a lower prevalence of OL, compared with the past, which might be the result of the massive public health education campaign against tobacco 314 .

The Natural Immune System

Natural killer (NK) cells are a major component of the immune system, which play important roles in host defences against cancer and microbial infections. NK cells are distinct from T or B lymphocytes, with a characteristic morphology of large granular cells, and can be readily identified by characteristic cell surface molecules. They have the ability to recognise and rapidly kill a wide array of tumour cells and also virus-infected normal cells. NK cytotoxic activity can be strongly augmented by interferon, interleukin-2, and other cytokines. NK cells are major producers of some cytokines, especially interferon gamma 41 they produce a neutrophil-activat-ing factor and upregulate polymorphonuclear leukocytes to kill Candida albicans 42 .

The Central Role of the Tryptophan Metabolic Pathway in Tolerance and Immunity to Fungi

The implication for IDO in immunoregulation in candidiasis may help to accommodate several, as yet unexplained findings. As C. albicans is a commensal of the human gastrointestinal and genitourinary tracts and IFN-y is an important mediator of protective immunity to the fungus, the IFN-y IDO axis may accommodate fungal persistence in a host environment rich in IFN-y. In its ability to downregulate anti-fungal Th1 response in the gastrointestinal tract, IDO behaves in a fashion similar to that described in mice with colitis where IDO expression correlates with the occurrence of local tolerogenic responses. Alternatively, the high levels of IL-10 production, such as those seen in patients with CMC, may be a consequence of IDO activation by the fungus, impairing antifungal Th1 immunity and thus favoring persistent infection (Romani & Puccetti, 2006b). In aspergillosis, the level of inflammation and IFN-y in the early stage set the subsequent adaptive stage by conditioning the...

Oral and Oesophageal Epithelium Model

A widely used three-dimensional model is the reconstituted human oral epithelium (RHOE). This model is constituted of human keratinocytes derived from the cutaneous carcinoma cell line TR146 and is commercialized by Skinethic Laboratory (Nice, France). The RHOE model resembles normal human oral epithelium and the pathological changes caused by Candida invasion are similar to the processes in human disease (Schaller et al., 1998). C. albicans has been found to grow intracellularly or traversing gap junctions of the epithelium, both in a similar proportion (Jayatilake et al., 2005). Using this epithelial cell model and a computer-assisted image analysis system the invasion of different Candida species was quantified, indicating that C. albicans is more invasive than others non-albi-cans Candida species (Jayatilake et al., 2006). Epithelial cells have mechanisms to sense the invasion by Candida spp. and respond by producing antimicrobial peptides (Lu et al., 2006). The RHOE model has...

Intestinal Epithelium Model

As long-term primary culture of human intestinal epithelial cells is still a challenge, most intestinal epithelial systems rely on immortalized cell lines (Grossmann et al., 1998). In order to clarify the ability of yeast and filamentous forms to influence adherence of C. albicans to the intestinal epithelium, the enterocyte cell lines Caco-2 and HT29 were tested. Candida-enterocytes interaction was observed with high-resolution scanning electron microscopy, while yeast adherence to enterocytes was quantified by using an ELISA assay (Wiesner et al., 2002) concluding that both C. albicans morphologies, yeast, and hyphae, could adhere to (and perhaps invade)

Dampening Inflammation and Allergy to Fungi A Job for Treg Cells

A number of clinical observations suggest an inverse relationship between IFN-y and IL-10 production in patients with fungal infections. High levels of IL-10, negatively affecting IFN-y production, are detected in chronic candidal diseases, in the severe form of endemic mycoses and in neutropenic patients with aspergillosis (Romani, 2004b). Fungal polysaccharides are known to negatively modulate CMI through the production of IL-10, a finding suggesting that IL-10 production may be a consequence of infection (Romani & Puccetti, 2006b). However, tolerance to fungi can also be achieved through the induction of Treg cells capable of finely tuning antifungal Th reactivity. Naturally occurring Treg cells operating in the respiratory or the gastrointestinal mucosa accounted for the lack of pathology associated with fungal clearance in mice with fungal pneumonia or mucosal candidiasis (Montagnoli et al., 2002, 2006). Distinct Treg populations capable of mediating anti-inflammatory or...

Alterations Of The Bloodocular Barrier In Diseased State

Infectious and noninfectious (uveitis and surgery) causes of ocular inflammation represent one category of retinal vascular disorders causing BOB breakdown. Fungi, viruses, and bacteria can be very destructive when they infect the eye. Candida endophthalmitis occurs in 5-30 of patients with disseminated Candida infections (15). Bacterial endophthalmitis is a severe and often blinding infection of the eye (26,69). Noninfectious inflam

Opportunistic infections

Pneumocystis carinii pneumonia is rarely encountered in patients receiving prophylactic therapy. Indications for prophylaxis are a CD4+ count below 200 cells L, HIV-related thrush, or unexplained fever for 2 or more weeks regardless of CD4+ count. Anyone with a past history of PCP should continue suppressive therapy indefinitely because of the high risk of relapse. CD4+ count 2 wk or oropharyn-geal candidiasis

Systemic nonhepatic infection and bacteremia

Hepatic involvement as just one component of a more generalized systemic infection occurs with some viruses (cytomegalovirus, Epstein-Barr virus), protozoa (Coxiella), parasites (malaria), and fungi (hepatosplenic candidiasis), particularly in immunosuppressed patients. Typhoid fever may cause an unusual hepatitis, but the jaundice in leptospirosis is due to hemolysis rather than hepatocellular injury.

Role Of Nk Cells In Host Defense Against Disease

NK cells may also be involved in resistance against some other types of microbial infections. A correlation has been observed between NK activity and resistance of mice to the malarial parasite Babesia microti 69 , Beige mice were highly susceptible to infection whereas heterozygous normal mice were resistant. There has also been some suggestive evidence for a role of NK cells in infection by Trypanosoma cruzi and this parasite has been shown to be susceptible to cytotoxicity by NK cells in vitro 70 , There is evidence that NK cells participate in eliminating tissue cells infected by mycoplasma or bacteria 71 , NK cells also participate in regulatory interactions between immune cells and nonimmune cells. For example, NK cells are capable of directly upregulating polymorphonuclear leukocytes to kill Candida albicans 71 , NK cells produce neutrophil-activating factors, which allow polymorphonuclear leukocytes to more effectively kill C. albicans and possibly other infectious organisms...

The Principal Functions Of Mononuclear Phagocytes

The phagocytic capacity of the macrophage is determined by the action of a composite of cell surface receptors, which can be classified generally as opsonic-dependent and opsonic-independent 16 . Opsonized pathogens may be recognized and internalized by receptors of the Fc portion of immunoglobulin, iC3b, and or fibronectin. In the absence of opsonization, the clearance of micro-organisms, including Candida sp., Cryptococcus neoformans, Pseudomonas aeroginosa, Pneumococcus carnii, Neiseria sp., Leischmanisa sp., Histoplasma sp., and Mycobacterium sp., has been shown to be accomplished by lectinophagocytosis through the action of macrophage mannan and c-glucan receptors.

Antifungal Oligonucleotides

Targeting RNA with oligonucleotides is emerging as an important therapeutic strategy to treat certain forms of cancer and some infectious states (Disney et al., 2001 Testa et al., 1999). The antisense oligonucleotide Vitravene (Galderisi et al., 1999), has proven to be effective in treating cytomegalovirus retinitis in AIDS patients intolerant, unresponsive or have contraindications to other treatment(s) of the infection. Gentasense, anti-bcl-2 anti-sense messenger RNA construct, and other oligonucleotide preparations (Childs et al., 2002) are proven potent against acute myeloid leukemia. Features that influence oligonucleotide affinity to bind target RNA and its nuclease stability can be accommodated into the sequence design (Freier & Altman, 1997). Recent evidence suggest that C. albicans takes up significant quantities of oligonucleotides in an energy-dependent manner, taken up oligonucleotides remain stable for 12 h (Disney et al., 2003). A 19-mer with a 2'-O-methyl backbone...

Papillary Hyperplasia

Papillary hyperplasia is typically seen in the hard palate. In many cases it is related to dentures as part of the clinical spectrum of denture-induced stomatitis 174 . Although Candida albicans is frequently invoked as the causal agent, in a significant number of cases there is no evidence of fungal infection. The large majority of cases involve the hard palate, particularly when this is high-arched, but similar lesions are occasionally seen on the dorsum of the tongue. The lesions form painless, nodu- Microscopy shows nodular, papilliferous hyperpla-sia of the epithelium and underlying fibrous connective tissue (Fig. 3.16). The surface usually shows parakerato-sis or less commonly orthokeratosis. There may be evidence of candidal infestation such as spongiform pustules or obvious hyphae. The underlying hyperplastic rete ridges often extend into the cores of the papillae, resulting in a striking pseudoepitheliomatous appearance. The corium often contains a dense chronic inflammatory...

C albicans Commensal and Pathogen

Candida albicans is commonly found in the gastrointestinal tract, oral cavity, and genital area as a harmless commensal. Based on recent studies in healthy individuals, asymptomatic oral carriage of Candida species is estimated to occur in 24-70 of children and adults, with a reduced frequency in babies less than 1 year of age (Table 5.1). Of isolates identified, the majority are C. albicans (38-76 in adults and children). Again, the frequency of C. albicans differs across different age groups, with a far greater proportion of isolates identified as C. albicans in young babies and in the elderly (Table 5.1). Higher oral carriage rates are found in HIV positive patients (Sanchez-Vargas et al., 2005a Liu et al., 2006) and diabetics (Belazi et al., 2005). Asymptomatic vaginal carriage of Candida species is estimated to occur in 21-32 of healthy women, with C. albicans representing 20-98 of identified isolates (Agatensi et al., 1991 Holland et al., 2003 Beigi et al., 2004 Beltrame et al.,...

Was the substance truly blood Was it the patients blood

Can result from gastroesophageal reflux disease (GERD). Children with bleeding esophagitis as a result of GERD are more likely to have a neuromuscular disease or hiatal hernia. Other causes of esophagitis include mechanical injury by a foreign body, chemical injury from caustic ingestion, medication (pill esophagitis), or infection (Candida albicans, Aspergillus, herpes simplex virus, cytomegalovirus).

An Expanding Molecular Toolbox for C albicans

DNA microarrays have been designed and transcript profiling performed to investigate changes in C. albicans gene expression by various groups including Eurogentec (Eurogentec website) in collaboration with the European Galar Fungail Consortium (European Galar Fungail Consortium website) and the NRC Biotechnology Research Institute, Montreal, Canada (Candida albicans NRC-Biotechnology Research Institute website) as well as many others. Transcript profiling experiments and their contributions to the understanding of C. albicans biology and pathogenesis have recently been reviewed by Garaizar et al. (2006). One of the major uses of transcript profiling for C. albicans has been to examine the global effects on gene expression caused by gene knockouts (Garcera et al., 2005 Garcia-Sanchez et al., 2005 Harcus et al., 2004 Lan et al., 2004 Lane et al., 2001 Lee et al., 2004 Lotz et al., 2004 Murad et al., 2001 Sohn et al., 2003 Tournu et al., 2005 Wang et al., 2006, 2007). These analyses have...

Antibacterial Screening of Tragia involucrata L Euphorbiaceae A Tribal Used Medicinal Plant

Reported the antimicrobial activity of traditional medicinal plants worldwide. Osmitopsis asteriscoides, a medicinal plant used in traditional drug preparations in South Africa, has been evaluated for antimicrobial activity against Candida albicans, Staphylococcus aureus mdPseudomonas aeruginosa 3 . The antimicrobial potential of Carpobrotus species (Aizoaceae) extracts was tested against S. aureus, P. aeruginosa, C. albicans and Mycobacterium smegmatis 4 . The efficacy of Warburgia ugandensis and Zanthoxylum chalybeum against common bacteria and fungi have also been investigated 5 . The oil obtained from the bark of Santiria trimera widely used by the traditional healers for wound healing 6 has also been investigated. Most people in South Africa with sexually transmitted diseases (STDs) first seek help from traditional healers

C albicanshost Interaction from the Fungal Point of View

Transcript profiling experiments have been carried out to investigate gene expression changes occurring when C. albicans interacts with macrophages (Lorenz et al., 2004), neutrophils (Rubin-Bejerano et al., 2003 Fradin et al., 2005), or whole blood (Fradin et al., 2005). Lorenz et al. (2004) demonstrated changes in transcription occurring when C. albicans is phagocytosed by macrophages (Lorenz et al., 2004). In the early phase, the cells demonstrated starvation responses, but in later stages switched to hyphal growth and switched to glycolytic growth. C. albicans cells also demonstrated induction of oxidative stress responses (Lorenz et al., 2004). In a murine model of systemic candidiasis, GFP-promoter fusions confirmed that the glyoxylate cycle and gluconeogenic genes were induced following phagocytosis by macrophages and neutrophils (Barelle et al., 2006). However, the majority of cells in an infected kidney were of hyphal morphology and expressed glycolytic genes, not glyoxylate...

Diagnosis and Treatment

Molecular diagnosis of disseminated candidiasis has been reviewed recently (Bretagne & Costa, 2005). Methods for detecting and quantifying C. albicans in biological samples include a real-time PCR for the mannoprotein 65 (MP65) gene, which demonstrated specificity for C. albicans and was highly sensitive (l genome for sera and urine and 10 genomes for blood) (Arancia et al., 2006). Nucleic acid sequence-based amplification has been shown to improve detection rates of C. albicans in blood cultures (Borst et al., 2001). A multianalyte profiling system has also been developed, where DNA probes specific for six medically important Candida species are linked to beads. Biotinylated PCR products from samples were then hybridised to the probes and bound amplicons detected fluorometrically (Das et al., 2006). It is suggested that a sample could be processed and analysed within 1 h post-PCR amplification. Other PCR methods based upon rRNA sequences to identify Candida species have also been...

Functional neutrophil disorders

An increased susceptibility to infection is well recognized in conditions associated with defects in phagocytic function. These defects occur in many systemic conditions, including diabetes mellitus, uremia, malnourishment, and alcohol ingestion, and following corticosteroid therapy. There are also well-recognized but exceedingly rare inherited defects of phagocyte function, the most striking being chronic granulomatous disease in which neutrophils are unable to kill catalase-positive micro-organisms such as staphylococci, Serratia, Candida, and Aspergillus. These organisms survive intracellularly, resulting in chronic local granulomatous inflammation. The defect in chronic granulomatous disease involves an enzyme in the respiratory burst of oxidative metabolism that accompanies phagocytosis. Unless the disease has previously been recognized in the family, the diagnosis is usually made when the clinical picture of recurrent infection prompts investigation of neutrophil and immune...

Treatment of nonbacterial infections

Up to a third of febrile neutropenic patients unresponsive to empirical antibiotics have systemic infections with either Candida or Aspergillus. Serious fungal infections also occur in patients undergoing bone marrow transplantation and organ transplantation, and in those who have received high-dose corticosteroid therapy. The mortalities from these infections are in excess of 35 per cent and 80 per cent respectively. This provides the rationale for administering empirical systemic antifungal drugs in patients with a persistent culture-negative fever 72 to 96 h after the commencement of empirical antimicrobial therapy or in the presence of pulmonary infiltrates. The newer imidazoles, such as fluconazole and itraconazole, have been extremely useful in the treatment of Candida, Cryptococcus, and Coccidiomycosis but have little activity against Aspergillus. Amphotericin B still remains the gold standard for the treatment of most fungal infections in immunocompromised hosts. The problems...

Inpatient Care After

Early and aggressive investigation and treatment are essential for the successful resolution of these infections. Careful physical examination, chest X-ray and abdominal ultrasound along with culture of blood, urine and wounds will usually uncover the source. Empirical treatment with antibiotics is often recommended when the source of the fever is undetermined. Antibiotics, which cover enterobacter and enterococci, are important in the early post transplant period. Yeast infections should always be suspected if a septic picture continues and there is no improvement with antibiotics. Children, who have been on pre transplant steroids, those with bile leaks or bowel perforations and those with arterial thrombosis have been shown to be at higher risk for the development of Candida infections.

Human Fungal Diseases

Another fungal pathogen is Candida albicans. This yeast is commonly found in the mouth, intestine, and, in women, in the vaginal tract. Generally, C. albicans exists in balance with other microorganisms, such as bacteria that live in and on the body. However, if the normal balance of microorganisms changes, such as when some antibiotics are used or when pregnancy or illness occurs, C. albicans can flourish and cause a disease called candidiasis, commonly known as a yeast infection.

Poorly characterised primary immune deficiency syndromes

There are a number of syndromes where susceptibility to certain types of infection is not associated with a clear pattern of inheritance and where the clinical picture is variable. Few are as severe as the specific syndromes referred to above. They include chronic mucocutaneous candidiasis, where there is persistent superficial skin and mucous membrane fungal infection, and where there may be defective T-cell regulation or dendritic cell function. CMC is also associated with a wide variety of autoimmune phenomena, particularly thyroid and adrenal disease, and different patterns of inheritance are seen in different kindreds.

Impaired carriage defense and the abnormal carrier state

Carriage defense is the first line of defense to fail in critically ill patients. The adherence of Gram-negative bacilli to mucosal cells is greatly increased. Stasis, an increase in gastric pH, and mucosal atrophy all lead to an explosive overgrowth of aerobic Gram-negative bacilli. The intravenous administration of broad-spectrum antibiotics excreted via saliva, bile, and mucus may eradicate both the indigenous flora and the sensitive 'community' potentially pathogenic micro-organisms. Consequently, resistant Gram-negative bacilli, Staph. aureus, and Candida species are selected, followed by overgrowth in the oropharynx and gastrointestinal tract. From a microbiological point of view, the impairment of carriage defense is associated with an abnormal carrier state. The incidence of abnormal carriage in mechanically ventilated patients is 60 to 90 per cent. High concentrations of mostly Gram-negative bacilli ( 10 8 ml), but also Staph. aureus and Candida species, can be found in...

Alternative Baeyer Villiger Biocatalysts

Some hydrolases can also be used to catalyze Baeyer-Villiger oxidations 26 . It has been shown that, analogous to cofactor-free haloperoxidases, serine hydrolases are capable of forming peroxyacids from carboxylic acids upon consumption of hydrogen peroxide. However, such a catalytic system lacks enantio-, regio-, and or chemoselectivity as the hydrolase merely acts as a peroxyacid-forming catalyst. A hydrolase does not offer a suitable active site for the peroxyacid and or substrate to bind. As a consequence the reaction of the formed peroxyacid with the carbonylic substrates will take place in solution without the steric confinement of an enzyme active site, prohibiting effective selectivity. Only in one specific case it has been reported that a lactone could be obtained with a moderate enantio-meric excess (21 ) using lipase B from Candida antarctica 27 . This selectivity can be explained by the fact that the chiral carboxylic acid itself also contained a carbonylic function...

Possible Scenarios Of Bioterrorism Attacks Distinguishing Victims From Perpetrators

Interpretation of a positive clinical test must take into account the health status of the person being tested. This is important for the practice of medicine and can have relevance when extended to forensic analysis. The following situations illustrate the concept. Individuals who have syphilis, a bacterial spirochetal infection, can typically have a positive FTA (fluorescent treponemal antibody) test for years. However while infected they would have a positive venereal disease research laboratory (VDRL) test. This reverts to negative with successful antibiotic therapy. There are some notable exceptions related to cross-reactive epitopes or autoimmune diseases. These are readily distinguishable by history and clinical information. Similarly individuals infected with tuberculosis will have a positive skin test (Mantoux), whereas the unin-fected healthy person will be negative. In certain instances, a sick person with a cell-mediated immune deficiency will be anergic, that is, he she...

Translocation and multiple organ failure

Translocation of bacteria and endotoxin to mesenteric lymph nodes or portal and venous blood has been demonstrated in animal models of gut ischemia and hemorrhagic shock, but the situation is more complex in humans. Translocation certainly occurs, but it has been associated with systemic symptoms in only one case report involving deliberate ingestion of Candida. In no other study has it been possible to establish a causal link between an acute precipitating illness, translocation, and remote organ injury. Indeed, there is a growing body of evidence which tends to disprove the theory. Studies of patients undergoing laparotomy for blunt trauma have failed to identify portal or systemic endotoxemia or elevation of tumor necrosis factor. Selective antibiotic decontamination of the gut may reduce systemic endotoxemia but has no significant effect on survival. Patients undergoing cardiopulmonary bypass demonstrate gut mucosal ischemia, hyperpermeability, and systemic endotoxemia, but these...

Acute Inflammation and Sleep

For example, rabbits develop different alterations in sleep when infected with Pasteurella multocida via the intravenous route, which causes septicemia, or the intranasal route, which causes pneumonia (Toth and Krueger 1990b). In general, rabbits with bacterial and fungal infections develop an initial increase and a subsequent decrease in the amount of time spent in SWS, whereas rapid eye movement sleep (REMS) is consistently reduced (Toth and Krueger 1989 Toth and Krueger 1990a). Infected rabbits also typically develop fevers, but the fevers generally persist beyond the period of enhanced sleep. In mice, the effects of infection with the fungal organism Candida albicans on sleep and temperature vary depending on the genetic background of the mice (Toth and Hughes, Compar Med, 2006).

Spoilage Organisms and Commodity Shelf Life

The spoilage microorganisms present on produce in MAP storage systems will be influenced by the particular commodity and by the atmospheres and temperatures employed. Initially, Gram-negative bacteria predominate in the microflora of typically low-acid vegetables while LAB, molds, and yeasts predominate on high-acid fruits. Indigenous microflora on vegetables that cause spoilage include a majority of Gram-negative bacteria, predominantly Pseudomonas spp., Enterobacter spp., and Erwinia spp. as well as Flavobacte-rium spp. and Xanthomonas spp. and Gram-positive LAB such as Leuconostoc mesenteroides and Lactobacillus spp. Indigenous yeasts and molds that cause spoilage include Cryptococcus spp., Candida spp., Rhodotorula spp., Fusarium spp., Rhizopus spp., Cryptococcus spp., Botrytis spp., Mucor spp., and Penicillium spp., among others.

Respiratory management

Intubated patients are more likely to develop colonization or infection with Gram-negative bacteria or Candida during the first 2 weeks after orthotopic liver transplantation. Patients who have been extubated and then relapse are susceptible to a range of organisms, including Aspergillus. If fungi are suspected, high-dose liposomal amphotericin should be started immediately. Cytomegalovirus and other opportunistic infections may appear after several weeks. Bronchoscopic lavage and brush biopsy should be performed early and repeated if negative. Selective antibiotic digestive decontamination reduces pulmonary infections in intubated patients

Infections and their prevention

Early infections are usually caused by Gram-negative bacilli after a few days these give way to mixed organisms, with Candida colonization of the oropharynx and Gram-positive colonization of catheters. Multiple-resistant bacteria may appear, usually in the sicker patients who are still ventilator dependent, with a sensitivity pattern depending on antibiotic utilization. Biliary colonization is common, but should not prompt antibiotic treatment in the absence of symptoms while the T-tube is in situ. Late infections include cytomegalovirus, herpesvirus, Pneumocystis, and invasive Aspergillus. Broad-spectrum antibiotics are usually prescribed routinely for the first 2 days. Oral nystatin, amphotericin, and low-dose Septrin are used for prophylaxis. Fluconazole is a useful systemic anti-Candida prophylactic which mildly inhibits cyclosporine A metabolism. Intravenous liposomal amphotericin should be prescribed (150 mg day for adults) if Candida or Aspergillus infection is suspected. There...

The Biological Species Concept and Species Taxa

(a) Absolute bridgeless gaps between sympatric species at a particular locality. The main phenomenon is reproductive isolation between species. These have objective reality, e.g., the five similar species of thrushes of the genus Hylocichla of which up to three inhabit the same woods in northeastern North America without the slightest intergradation, and Mayr (1942e 148 1943e, 1946l, 1955e, 1963b) continued to illustrate the absolute gaps between sympatric species by the five thrushes of the genus Hylocichla in northeastern North America several of which may occur at the same locality.10 They are very similar, but completely separated from one another by biological discontinuities. However, he emphasized that reproductive isolation in nature does not necessarily mean sterility. Ability to cross in captivity is not a decisive test. 10 Four of these spotted thrushes are currently included in the neotropical genus Catharus and only the Wood Thrush (Hylocichla mustelina) remains in this...

Patients at Risk for Pneumocystis carinii Pneumonia

Identification of HIV-infected individuals at high risk for PCP who have not had an initial bout is more problematic. At least 20 of AIDS patients will never have an episode of PCP, and the number of HIV-infected individuals is large compared to those who have had PCP. Nevertheless, both clinical and immunological status, have been used to determine risk. The initial determinants of risk were case reviews of patients presenting with PCP 28 . In addition to having prodromal symptoms, these patients commonly experience weight loss, hairy leukoplakia, and mucocutaneous candidiasis. In these persons, PCP usually occurs when an absolute CD4 lymphocyte count normally between 800 and 1,000 cells mm3 decreases to less than 200 cells mm3 28,29 . These studies could not determine what percentage of unprophylaxed HIV-infected patients with similar symptoms and immuno-logical status would develop PCP. Recently, however, in the Multicenter AIDS Cohort Study (MACS) of 1,660 homosexual males, the...

Prevention and Treatment

Vulvovaginal Candidiasis Vulvovaginal candidiasis is the second most common cause ofvagi-nal symptoms after bacterial vaginosis. As with bacterial vaginosis, vulvovaginal candidiasis appears to follow a disruption of normal flora. As the name indicates, the infection often involves not only the vagina, but the woman's vulva, or external genitalia, as well.

Drosophila melanogaster A Fruitful Model

The most prominent pathogen studied in D. melanogaster is P. aeruginosa. For this pathogen it could be shown that the virulence factors required for full infec-tivity in Drosophila are the same as for mammals 53 . Moreover, the verification of the activation of the type III secretion system upon entry of the bacteria into the animal opens up the prospect of Drosophila as a real in vivo model for infection with this pathogen 54 . Further pathogens currently under investigation are Ser-ratica marcescens, Listeria monocytogenes, and Mycobacterium marinum. Infections with fungi can also be monitored. In one study the authors infected immune-deficient flies with different Candida albicans mutants. They found that virulence patterns against Drosophila in these strains reproduced those in a murine model.

Primary Immunodeficiency Diseases

Individuals with defects in cellular immunity are prone to fungal, protozoal, and viral infections, such as Candida albicans, cytomegalovirus, and Pneumocystis carinii, since cell-mediated immune responses are the primary defenses against these types of infection. Because of the role of cell-mediated immunity in tumor surveillance, these individuals will also demonstrate an increased incidence of malignancy if they survive long enough.

Approaches To Biocontrol In Postharvest Situations

The purpose of antagonists is to colonize rapidly possible infection sites and protect them from infections. Usually, populations of effective antagonists increase rapidly initially and stabilize thereafter. Such a colonization pattern can be seen in fruit wounds treated with yeasts such as Candida oleophila 3,4 , Cryptococcus albidus 5 , C. laurentii 6 , and Pichia membranefaciens 7 and bacteria such as Pseudomonas syringae 2 . However, wounds can have a narrow window for optimal colonization as they dry out 8 . This requires that application takes place as soon as possible after harvest and handling, as antagonists usually have little curative activity 2 . Also, wounds on oil glands of citrus fruit were found to be more difficult to colonize by C. oleophila, resulting in poor decay control 4 . culture media with low water activity to help Candida sake adapt to water stress 15 . Such physiologically modified yeasts were better adapted to So far, the induction of disease resistance in...

Clonality and Adaptation to the Niche

An extensive study using multilocus microsatellite typing and 169 isolates representing a number of geographically distinct regions lead to the conclusion that P. marneffei is one of the most clonal species of fungus characterized (Fisher et al., 2005). Ecological studies performed in a number of opportunistic pathogens have revealed an apparent link between asexuality and pathogenicity. Fungi such as C. neoformans, Candida albicans, and Aspergillus fumigatus, together with P. marneffei show extensive levels of clonality in the environment with very low levels of recombination (Fisher et al., 2005 Heitman, 2006). The hypothesis is that clonality is a hallmark of organisms that are highly adapted to their environments. Despite this, all of these pathogens possess the genes which are required for mating and mating has been clearly demonstrated for C. neoformans and recently for C. albicans (Hull & Johnson, 1999 Lengeler et al., 2002 Paoletti et al., 2005). A recent report documented the...

Disadvantages of Biocontrol Agents

Some biocontrol agents do not produce spores and consist only of bacterial cells or fungal mycelia, and as a result the shelf life of a biocontrol product may not match that of a chemical product. Maintaining a high degree of viability and efficacy in formulated biocontrol agents can be a challenging task. As with most pesticides, biofungicides are commonly dehydrated into powder or concentrated into liquid formulations. Such processes can have a negative impact on disease control efficacy. As most information on the formulation of biopesticides is proprietary, there is limited literature on the subject. For example, freeze-drying of Candida sake caused cell mortality and greatly affected control of blue mold of apple, compared to that obtained with fresh cells 43 . Protective agents and additives, such as skimmed milk, peptone, or lactose, at the time of freeze-drying and rehydration can somewhat help reduce cell mortality of C. sake 43 . As mentioned above, growing...

Assessment of Allergenicity

Naturally occurring atopic allergens have few physiochemical characteristics to distinguish them from other antigens. All are proteins or glycoproteins, although high molecular weight polysaccharides that react with IgE have been obtained from Candida albicans. Most protein allergens that have been identified are acidic, with molecular weights ranging from 5,000 to 60,000 daltons. It has been postulated that larger molecules cannot readily penetrate the mucous membranes. Highly reactive allergens of lower molecular weight are described in conjunction with ragweed and grass pollens. The antigenic determinants that react with IgE antibody molecules have not been clearly identified for most allergens, although it is postulated that there must be at least two such groups on each allergen molecule to trigger the allergic response. The sequence of amino acids in some determinant groups, with less regard for conformation of the protein molecule, is most important for the major codfish...

D Other Biological Activities

Another interesting biological activity of Monascus is associated with its antibiotic activities against Bacillus subtilis and Candida pseudotropicalis. The active compounds have been reported as rubropunctatin and monascorubrin. Immunosup-pressive activity on mouse T-splenocytes has been most pronounced with compounds monascin and ankaflavin. The immunosuppressive effect of monascin is more pronounced than that of rubropunctatin and monascorubrin. Conversely, rubropunctatin and monascorubrin show substantially higher antibiotic effects. Monascus preparations have also shown favorable dietetic effects, involving reduction of serum cholesterol and triglycerides in mice.125

Imidazoles and triazoles

Miconazole, ketoconazole, fluconazole, and itraconazole are active against most fungi except Aspergillus species. They act by inhibiting the production of the fungal cell membrane. Miconazole is not reliable in systemic infections, and ketoconazole is not effective against deep candidiasis. Fluconazole is well absorbed orally and can be given intravenously. Its long half-life allows once-daily dosing. It penetrates most tissues and is excreted renally, largely unchanged. Dosage must be reduced in renal failure. Adverse effects are rare. It is highly effective in mucosal candidiasis, but efficacy in other systemic infections is less well established.

Major Antigenic Molecules of P brasiliensis

Gp43 gene was cloned, sequenced, and expressed in Escherichia coli as a recombinant fusion protein (Cisalpino et al., 1996). It encodes a polypeptide of 416 amino acids with a leader sequence of 35 residues and is present in one copy per genome as shown by Southern blotting and chromosomal mega-restriction analysis. The open-reading frame has two exons and one intron. As mentioned, the mature protein has a single N-glycosylation site. Sequences containing B cell epitopes are still under study chiefly by examining the reactivity of anti-gp43 mAbs. The T cell epitope responsible for delayed-type hypersensitivity reactions, and CD4+ T cell proliferation, has been mapped to a 15-mer peptide called P10 with the sequence QTLIAIHTLAIRYAN (Taborda et al., 1998). The hexapeptide HTLAIR with varying flanking regions is essential for the immune cellular response. Both gp43 and P10 protect mice against the i.t. challenge with virulent P. brasiliensis. Gp43 has 54-60 homology and 50 identity with...

Host biology Aspects unique to pediatric patients

Anatomical considerations are important throughout infancy, but particularly in preterm neonates. Due to the reduced thickness of the skin, the use of medical devices and the moist environment, preterm neonates have a particular susceptibility to developing primary cutaneous aspergillosis and zygomycosis 1, 2 . Similarly, the extremely tenuous gastrointestinal wall structures lead to a unique propensity to primary invasive gastrointestinal mold infections with precipitous perforation, a pattern that is relatively uncommon in other settings 3, 4 . The comparably small diameter of blood vessels provides a nidus for catheter-associated Candida thrombophlebitis, -thrombosis, and endocarditis 5-8 life-threatening Candida laryngitis and epiglottitis may occur in immunocompromised infants and young children for similar anatomical reasons 9-12 . In neonates, physiological differences such as the larger fractional water content, the smaller plasma protein fraction, relatively larger organ...

Pediatric pharmacology of established antifungal agents

Uncomplicated candidemia or invasive candidiasis Acute dissem. candidiasis with hemodynamic instability With the advent of new antifungal agents and following the completion of pivotal clinical Phase III trials, a few indications are left for antifun-gal treatment of opportunistic mycoses with conventional deoxycholate amphotericin B (Tabs 2-4). These include candidemia and acute disseminated candidiasis, particular in neonates, and induction therapy for crypto-coccal meningitis. The recommended daily dosage in these settings ranges from 0.7 to 1.0 mg kg day administered over 2-4 h as tolerated. Treatment promised patients. The overall response rates in these trials ranged from 53 to 84 in patients with invasive candidiasis and 34 to 59 , respectively, in patients with presumed or documented invasive aspergillosis 201, 214 . A few randomized, controlled trials have been completed in which one of the new formulations has been compared to DAMB 199, 205, 215 . These studies have...

In vivoex vivo Studies

G-CSF is produced by macrophages, fibroblasts, and endothelial cells in virtually all organs in the body. It exerts its biological actions on precursors as well as on mature PMNs. In particular, G-CSF increases the number of circulating neutrophils, by stimulating the proliferation and differentiation of myeloid progenitor cells, and moreover enhances their phagocytic activity (Antachopoulos and Roilides, 2005). Administration of G-CSF in neutropenic animal models of invasive candidiasis, aspergillosis, or trichosporonosis was associated with faster recovery from neutro-penia and improved survival (Hamood et al., 1994 Muranaka et al., 1997 Graybill et al., 1998). Consequently, theoretically, the administration of G-CSF would be beneficial in resolving scedosporiosis. No animal model studies have reported on the effects of G-CSF on the outcome of experiment fusariosis up to date. Ortoneda et al., in an immunosuppressed murine model of invasive infection by S. prolificans, demonstrated...

Selected management issues of invasive fungal infections

Treatment and prevention of neonatal invasive candidiasis As outlined earlier, preterm infants of very low birth weight are at considerable risk to develop invasive Candida infections. In the U.S., Candida spp. currently represent 9-13 of blood culture isolates obtained from NICUs. More recent case series indicate infection rates of s 5 in infants of 1500 g birth weight infection rates in infants 1000 g, however, are between 8 and 28 . In contrast, the epidemiology of invasive Candida infections in European countries has been less well investigated however, infection rates appear to be considerably lower than those in the U.S. Invasive Candida infections in preterm infants are caused predominantly by C. albicans and C. parapsilosis. They are associated with intravas-cular catheters, intracranial shunt systems, use of broad-spectrum antibacterial agents and corticosteroids, mucocutaneous colonization and parenteral hyperalimentation. While most cases present with candidemia,...

Differential diagnosis

Antigen injection (Candida, mumps) Immunotherapies hasten immune recognition of HPV by the body. Imiquimod 5 cream is an immune response modifier approved in the United States for the treatment of genital warts. When applied to the skin, Imiquimod induces production of interferon-a, TNF-a, IL-1, IL-6, and IL-8. Many small case series or single case reports have anecdotally reported a variety of successful regimens of Imiquimod application for common warts in children. The most effective regimen reported has been a twice-daily application. Usage under a diaper is inadvisable, as severe ulceration may result 70-76 . Other topical immunotherapies used in children include diphencyclopropenone (DCP) and squaric acid (SADBE) 77-79 . SADBE has been described for office or home usage, while DCP is generally used in-office 80-82 . Clearance rates in published studies have varied from 58-90 with eczematous side effects being common and rare urticaria 79 . Oral cimetidine in standard pediatric...

The Molecular Endocrinology Of Diabetes Mellitus

The most characteristic features of this syndrome are chronic mucocutaneous candidiasis, hypoparathyroidism, Addison's disease, and T1ADM other features include other autoimmune endocrinopathies (such as hypothyroidism or hypogonadism), malabsorption syndromes, pernicious anemia, and alopecia. The gene for this disorder is the autoimmune regulator or AIRE (OMIM 607358), which appears to be a transcription factor. The exact mechanism by which it causes the syndrome is not known (131,132). 7.4. TYPE 2 DIABETES A POLYGENIC FORM OF DIABETES Type 2 diabetes mellitus (T2DM) arises out of a combination of insulin resistance and insulin secretory defects. This interaction is, in turn, influenced by environmental factors such as diet, obesity, and physical activity. T2DM is known to have an even stronger genetic predisposition than T1DM, with a high concordance rate among identical twins (approx 80 as opposed to dizygotic twins, for whom the risk is approx 10 ) and an...

Epidemiology and presentation of invasive fungal infections in pediatric patients

Epidemiology Fungi

Candida spp. colonize the vaginal tract of approximately 30 of pregnant women very rarely, they can become the cause of chorioamnionitis and intrauterine infection 29, 30 . Candida rapidly colonizes the mucocutaneous surfaces 31, 32 in healthy infants, this colonization may result in thrush and diaper dermatitis 31 . In hospitalized, ill neonates, however, Candida has evolved as important cause of life-threatening invasive infections, particularly in very low birth weight infants. Candida spp. now account for 9-13 of all bloodstream isolates in neonatal intensive care units (NICUs) 33, 34 . In the U.S., Candida spp. currently are the third most common cause of late onset sepsis, and second only to polyresistant Enterobacter spp. in mortality 35, 36 . Case series indicate that invasive candidiasis occurs in up to 5 of infants with a birth weight of 1500 g and in 8-28 of infants with a birth weight of 1000 g the crude mortality associated with these infections ranges from 15 to 30 with...

Vaginitis or Vulvitis

Can also cause vaginitis but typically causes intense pruritus. Labia may be pale or erythematous with satellite lesions. Vaginal discharge, if present, is usually thick and adherent, with white curds. 3. Other causes. In sexually active adolescents, the most common causes include bacterial vaginosis ( fishy, foul-smelling discharge), candidal vulvovaginitis (white, cottage-cheese'-appearing discharge), and trichomoniasis (malodorous yellow, frothy discharge). D. Contact or Candidal Dermatitis. Frequently seen in infants wearing diapers because the diaper area is warm, often moist, and frequently contaminated by feces laden with organisms. Failure to change diapers frequently is a major predisposing factor. Harsh soaps, irritating chemicals, and detergents contribute to the process. 2. Candidal dermatitis. Appears as a bright red eruption, with sharp borders and pinpoint satellite papules and pustules tends to involve the intertriginous areas.

Miscellaneous Topical Antifungal Agents

A 55-year-old obese woman with adult-onset diabetes mellitus has been receiving amoxicillin for treatment of an acute exacerbation of chronic bronchitis. After a week of therapy, the patient develops dysuria and increased urinary frequency. Urinalysis shows 10 to 50 white blood cells per high-power field, and Gram stain of urine shows many budding yeasts. Which antifungal agent would be best in treating this patient for Candida cystitis

Fungal Wound Infections


Fungal infections of wounds are unusual in economically developed countries, except that the yeast Candida albicans can be troublesome in severe burns and in those with wounds and underlying diseases such as diabetes and cancer. This yeast, commonly present among the normal flora and kept in check by it, becomes pathogenic when the competing microorganisms are eliminated, as in individuals receiving antibacterial therapy. Other fungal wound infections are much more common in impoverished people around the world. For example, Madura foot, a condition caused by various species of fungi, occurs in areas of the world where foot injuries are common, resulting from lack of shoes. Named after the city in India where it was first described, Madura foot is characterized by swellings and draining passageways that spit out yellow or black granules of fungal material. Only a minority of those with foot injuries contract the disease despite exposure to the same fungi, suggesting that other factors...

Origanum onites oil was used in this pharmacological test. The test revealed antihistaminic activity of the oil

Skin Diseases Caused by Fungi

Skin Disease

Diseases caused by fungi are called mycoses. Earlier in this chapter, we mentioned the role of normal flora yeast of the genus Malassezia in causing mild skin diseases, such as tinea versicolor. Other fungi are responsible for more serious infections of the skin, although even in these cases the condition of the host's defenses against infection is often crucial. The yeast Candida albicans (figure 22.26) may live harmlessly among the normal flora of the skin, but in some people it invades the deep layers of the skin and subcutaneous tissues. In many people with candidal skin infections, no precise cause for the invasion can be determined. Certain molds Figure 22.26 Candida albicans (a) Causing a diaper rash (b) Gram stain of pus showing C. albicans yeast forms and filamentous forms called pseudohyphae.

Resistant or recurrent cases

Cultures are helpful in determining whether a non-candidal and difficult-to-treat species is present. Patients with recalcitrant disease should be evaluated for diabetes and HIV. A. One-third of patients with vaginal symptoms will not have laboratory evidence of bacterial vaginosis, Candida, or Trichomonas.

C albicans Cell Surface

Proteomic analysis of immunogenic proteins in a mouse model of systemic candidiasis identified more than 31 immunoreactive proteins including glycolytic enzymes, such as fructose bisphosphate aldolase, triose phosphate isomerase (Tpilp), glyceraldehyde-3-phosphate dehydrogenase, phosphoglycerate kinase, triose phosphate isomerase, enolase, and pyruvate kinase (Pitarch et al., 2001). Metabolic enzymes, such as methionine synthase, Imh3p, alcohol dehydrogenase and aconitase, and heat-shock proteins from the Hsp70 family were also identified as immunogenic. Different antibody profiles were identified for strains of mice with differing susceptibility to systemic C. albicans infection. Eno1p was the dominant immunogenic protein in BALB c mice (most resistant), with the more susceptible mice having a stronger reaction to methionine synthase, Hsp70 proteins, and phosphoglycerate kinase (Pitarch et al., 2001). In surviving and non-surviving patients with candidiasis differing antibody...

Upper gastrointestinal hemorrhage above the lower ileum

Upper Gastrointestinal Hemorrhage

Reflux esophagitis is another common cause of esophageal bleeding. This diagnosis is suspected when guaiac-positive stools or small amounts of melena are discovered in a patient experiencing frequent bouts of heartburn, particularly when in a recumbent position. The disorder results from repeated reflux and retention of acid-peptic gastric contents in the esophagus as a result of both reduced resting pressure at the level of the inferior esophageal sphincter and delayed esophageal emptying. While the inflammatory process is usually mild and bleeding is slight, actual mucosal dysplasia (Barrett epithelium) leading to ulcers and strictures may occur in severe chronic cases. In immunocompromised patients in particular, several types of mycoses (especially candidiasis) or viral infections may cause extensive esophagitis and dysphagia, usually with minor bleeding. These disorders are generally responsive to specific chemotherapeutic drugs. Cancer of the esophagus is unlikely to cause major...

Epidemiology and transmission

Cytomegalovirus Epidemiology

Significant differences in CD4 lymphocyte numbers were observed among 12 AIDS-defining illnesses, oral candidiasis, and asymptomatic infection, allowing them to be grouped into five general catgories based on mean CD4 count (a) asymptomatic infection (ASX) - CD4 greater than 500 mm3 (b) oral candidiasis (O-C) and tuberculosis (TB) - range 250-500 mm3 (c) Kaposi's sarcoma (KS), lymphoma (LYM), and cryptosporidiosis (CRS) - range 150-200 mm3 (d) PCP, disseminated Mycobacterium avium complex (MAC), herpes simplex ulceration (HSV), toxoplasmosis (TOX), cryptococcosis (CRC), oesophageal candidiasis (E-C) - range 75-125 mm3 (e) cytomegalovirus retinitis - less than 50 mm3 (Crowe et al. 1991). This correlation depicted in Graph 12.1, can explain the relative difference in occurrence of TB and PCP in Africa as compared with Europe.

Pityriasis Versicolor

In tinea versicolor, fungus does not grow in standard fungal culture media (eg, Sabouraud's dextrose), but KOH examination shows the abundant spaghetti and meatballs pattern of short hyphae and round spores. Pityrosporon ovale is part of the normal flora of skin in amounts that are not detectable on KOH examination. It is a yeast infection, and it is not a dermatophyte infection.

Novel Therapies Antifungal Monoclonal Antibodies

MAbs raised against a number of intracellular or expressed fungal cell components have also been developed and tested in animal models. Anti-gp70, a MAb raised against the 70 kDa intracellular secreted glycoprotein component of P. brasiliensis, abolished lung granuloma formation in infected mice (De Mattos Grosso et al., 2003). C. albicans strains susceptible to the yeast killer toxin (KT) activity take cover by Abs generated in the host against KT (competing Abs) or its receptor (KTR) on C. albican surface (blocking Abs). Anti-idiotypic MAbs that neutralize anti-KT or anti-KTR Ab activity thus allowing KT activity against the fungus to ensue can circumvent the evasiveness of pathogenic C. albicans. An IgM anti-idiotypic MAb generated in mice immunized with the anti-KT MAb (KT4) was reported to have a potent killing activity against KT-sensitive C. albicans strains (Polonelli et al., 1997). A decapeptide containing the first three amino acids of the light chain CDR1 of a KT...

Antifungal Drugs antimycotic drugs

Fungi, such as Candida spp. (yeast), are normal flora of mouth, skin, intestine, and vagina. Candidiasis might be an opportunistic infection when the defense mechanisms are impaired. Antibiotics, oral contraceptives, and immunosuppressives may alter the body's defense mechanisms. Infections can be mild (vaginal yeast infection) or severe (systemic fungal infection). There are four groups of anti-fungal medications. They are Polyenes such as amphotericin B are the drug of choice for treating severe systemic infections. It is effective against numerous diseases including histo-plasmosis, cryptococcosis, coccidioidomycosis, aspergillosis, blastomycosis, and candidiasis (system infection), however, it is very toxic. It is not absorbed from the GI tract so it cannot be given by mouth. Nystatin (Mycostatin) can be given orally or topically to treat candidal infection. It is available in suspensions, cream, ointment, and vaginal tablets. It is poorly absorbed via the GI tract but the oral...

Trichomonas vaginalis

Trichomonas vaginalis is a common sexually transmitted pathogen causing vaginitis, exocervicitis, and ureteritis in women (Fauts and Kraus 1980). Trichomonas vaginalis infections has been suggested to play a role in the pathogenesis of pre-term birth, pre-term rupture of membranes and delivery of low-birth-weight infants (Cotch et al. 1991 Read and Klebanoff 1993). Recently T. vaginalis infections has been implicated as a cofactor in the transmission of HIV (Laga et al. 1993). Trichomonas vaginalis infection are frequently asymptomatic, and early, accurate diagnosis are required for specific treatment. Routine diagnosis of T. vaginalis usually depends on direct microscopic identification of the parasite in wet mount preparations. However, wet mount examinations detects only 60 and the direct immunofluorescense using monoclonal antibodies detect 86 of culture positive cases in women. Although culture is considered the most reliable diagnostic method, with a sensitivity of 90 for...

The pGKL1 Encoded Zymocin a Biogenesis

The zymocin encoding killer plasmids pGKL1 and pGKL2 have been transferred to other yeast species, such as Kluyveromyces marxianus (synonyms K. fragilis and Candida pseudotropicalis) and S. cerevisiae (Gunge and Sak-aguchi 1981 Gunge et al. 1982 Sugisaki et al. 1985). Irrespective of their host they confer the ability to secrete zymocin, suggesting toxin biogenesis to be similar. Indeed, S. cerevisiae cells harboring pGKL1 and pGKL2 were shown to secrete zymocin consisting of correctly processed subunits. Moreover, mutations in the KEX2 gene, which is homologous to K. lactis KEX1, prevent secretion of both holotoxin and the aP-precursor (Stark et al. 1990 Tokunaga et al. 1990).

Recent advances in early diagnosis and preemptive therapy

Early diagnosis and rapid initiation of effective antifungal chemotherapy is paramount to the successful management of invasive mycoses. The microbiological diagnosis should be attempted if feasible in all cases of suspected invasive fungal infection, and the organism identified at the species level. Because of the lack of its predictive value in other settings, the performance of in vitro susceptibility testing is currently reserved to Candida species vs. fluconazole and flucytosine, respectively. Additional in vitro testing of other organism drug combinations may be indicated in refractory infections and within surveillance programs 170 . Improved blood culture detection techniques, such as the lysis-cen-trifugation and the BacTec Alert system, are able to detect candidemia earlier and more frequently than conventional systems 171 . However, it must be emphasized that candidemia is only one manifestation of invasive candidiasis, and that single organ or early disseminated...

Category Ed50 Munoz Et Al

Decreasing toxicity and increasing target specificity (Abuhammour and Habte-Gaber, 2004 Ng et al., 2003). Incorporating AMB into phospholipid vesicles (Liposomes) or cholesterol esters permit delivery of larger amounts of the drug with minimal nephrotoxicity. AMB lipid complex (AMBLC) was the first lipid-formulated AMB product to be approved by the FDA for clinical. The lipid-formulated AMB colloidal dispersion (AMBCD), which consists of disc-like structures of cholesteryl sulfate complexed with AMB in a 1 1 molar ratio received FDA approval in 1996. Addition of cholesterol to the phospholipid bilayer enhances liposome stability, decrease rate of clearance, and prolong halflife. The clinical response of patients with invasive aspergillosis (IA) was slightly better when treated by a lipid formulation compared with conventional AMBD (Bowden et al., 2002 Reichenberger et al., 2002 Wingard et al., 2000). Lipid formulations used empirically in neutropenic cancer patients resulted in...

Superficial Mucosal Infections

Superficial mucosal lesions occur in the oral and vaginal cavities and are commonly called 'thrush'. These infections can occur in both immunocompetent and immuno-compromised persons. Oral thrush, or oral candidiasis, is a common problem seen in infants, the elderly, and in cancer patients, particularly those with haematological malignancies, receiving chemotherapy, or receiving head and neck radiotherapy. It is characterised by white growth on mucous membranes of the oral cavity, which have underlying red areas when the fungal growth is scraped off. The majority of isolates associated with oral candidiasis were identified as C. albicans (63-84 ) (Sanchez-Vargas et al., 2005a, b Davies et al., 2006). Risk factors associated with oral candidiasis include xerostomia (dry mouth) and denture wearing (Davies et al., 2006), as well as poorly controlled diabetes mellitus (Guggenheimer et al., 2000) and immunosuppression. The frequency of oral candidiasis, but not oral carriage of Candida...

Adverse Effects and Contraindications

Inhaled corticosteroids are generally well tolerated. In contrast to systemically administered corticosteroids, inhaled agents are either poorly absorbed or rapidly metabolized and inactivated and thus have greatly diminished systemic effects relative to oral agents. The most frequent side effects are local they include oral candidiasis, dysphonia, sore throat and throat irritation, and coughing. Special delivery systems (e.g., devices with spacers) can minimize these side effects. Some studies have associated slowing of growth in children with the use of high-dose inhaled corticosteroids, although the results are controversial. Regardless, the purported effect is small and is likely outweighed by the benefit of control of the symptoms of asthma.

Using Microorganisms to Nourish the World

Yeasts are considered the most promising large-scale source of single-cell protein. They multiply rapidly, are larger than bacteria, and are more readily acceptable as a potential food. The most suitable type ofyeast depends on the growth medium employed. The various genera of yeasts utilize differing carbohydrate sources and conditions for growth. For example Kluyveromyces marxianus can be grown on whey, a by-product ofcheese-making Saccharomyces cere-visiae can grow on molasses, a by-product of the sugar industry and Candida utilis can multiply on cellulose-containing by-products ofthe pulp and paper industry. Most ofthese wastes must be supplemented with a nitrogen source, as well as various vitamins and minerals, in order to support the growth of yeasts or other microorganisms.

Pediatric populations at risk for invasive infections

The pediatric populations at risk can be defined by specific predisposing defects in host defenses and several additional, non-immunological factors. In general, deficiencies in the number or function of phagocytic cells are associated with invasive infections by opportunistic fungi, such as Candida spp., Aspergillus spp., zygomyces spp. and a large variety of other, less frequently encountered yeasts and molds. In contrast, deficiencies or imbalances of T lymphocyte function are linked to mucocutaneous candidiasis and invasive infections by Cryptococcus neoformans and the dimorphic moulds (Fig. 1). Non-immunological factors include the necessary exposure to the organism, preexisting tissue damage, and, limited to Candida spp., the presence of indwelling vascular catheters, colonization of mucous membranes, the use of broad-spectrum antibiotics, parenteral nutrition, and complicated intra-abdominal surgery 28 .

Comparison of Gene Expression Profiles of Macrophages and Dendritic Cells In Vitro Upon Infection with Different

Several studies 1-3 compared the responses of macrophages or dendritic cells upon infection with different pathogens. Huang et al. 1 determined the gene expression profiles of human monocyte-derived dendritic cells in response to Escherichia coli SD54, Candida albicans, and influenzavirus as well as to their molecular components by using oligonucleotide arrays representing 6800 genes. While 166 genes were found to be regulated in common by all these pathogens, 118 genes were specifically regulated by E.coli, 58 specifically by influenzavirus whereas C. albicans only modulated the expression of a subset of E. coli-regulated genes. The 166 common regulated genes may represent a core response of dendritic cells against microbes, while other genes specifically reflect the interaction with a certain type of pathogen. Interestingly, rapidly after cell contact with any of the pathogens, a decline in the transcripts of genes associated with phagocytosis and pathogen recognition was observed,...

Genetic Variation in Sleep Under Normal Conditions and during Inflammatory Disease

A growing body of literature indicates that variation in the inflammatory response may influence sleep, and perhaps that variation in sleep may impact recuperation and prognosis. Numerous studies have shown that marked but varied alterations in sleep develop during infectious diseases and inflammatory processes. For example, in mice, influenza infection leads to increased somnolence in some strains, but impaired sleep in others (Toth and Verhulst 2003). Inbred strains of mice also vary in their sensitivity and responses to numerous infectious challenges. Strain-related differences in the cytokine milieu and other factors produced over the course of an infection could contribute to quantitative and qualitative variation in sleep during infectious diseases. For example, the sleep responses to some viral challenges, but not others, are influenced by the gene If-1, which regulates production of the cytokine IFN-y in response to viral challenge (De Maeyer and De Maeyer-Guignard 1970)....

C albicans and the Host Immune System

An elegant study by Romani et al. (2004) demonstrated that different macrophage surface receptors were involved in phagocytosis of unopsonised yeast and hyphal cells (Romani et al., 2004). Blocking the mannose receptor had the greatest effect on phagocytosis of yeast cells with CR3 and dectin-1 also having significant effects. However, the mannose receptor had no effect on phagocytosis of hyphae, which was mediated mostly by CR3, dectin-1, and the FcyRII III receptors. Binding of the mannose receptor was associated with a Type I cytokine responses, whereas entry via the FcyR receptors produced a Type II response (Romani et al., 2004). The mannose receptor, however, does not appear to be essential for host defence or phagocytosis in an intraperitoneal (i.p.) infection model of candidiasis (Lee et al., 2003). in anti-candidal defence (Blasi et al., 2005). TRL2-deficient mice were also shown to be more susceptible to C. albicans infections (Villamon et al., 2004c), with macrophages...

Other somatoform conditions

A number of specific somatic syndromes have been described over the last several decades. These specific syndromes are sometimes defined by the particular somatic symptoms experienced (e.g. fibromyalgia, irritable bowel syndrome, chronic fatigue syndrome) and sometimes by particular beliefs about aetiology (e.g. multiple chemical sensitivity, systemic candidiasis, electrical allergy). In every case, controversy persists about whether the somatic symptoms should be considered 'medically unexplained' (that is to say a somatoform disorder). Community surveys suggest that non-specific symptoms (such as fatigue or diffuse musculoskeletal pain) are common, but that the prevalence of strictly defined syndromes (such as fibromyalgia or chronic fatigue syndrome) varies considerably with the criteria applied 4 d546 aDd 47 Most of these syndromes appear more often in women than in men.(4 ,49) Both community(4 l95.0) and primary care surveys 1.) have found several of these syndromes to be...

Clinical Presentation

Gests that valacyclovir is an effective alternative in this population. Patients in any group, except D-R-, receiving OKT3 or anti-lymphocyte antibodies are considered candidates for GCV prophylaxis since their risk of CMV disease is substantially increased. Prophylaxis is continued for the first three months after transplantation. One exception to this approach is lung and heart-lung recipients that fall into the D+R- group since they are at the highest risk, intravenous full dose GCV for two weeks and followed by maintenance doses to complete three months of prophylaxis after transplantation seem warranted to prevent severe disease. Mucocutaneous involvement presents as painful vesicular and ulcerative lesions the appearance may be different than that observed in immunocompetent individuals. Pneumonitis is rare and usually seen in conjunction with other pulmonary infections. Ulcerative esophagitis manifests as dysphagia and odynophagia and can resemble or occur concomitantly with...

The Adaptive Immunity Th1 Th2 and Th17 Cells

Antifungal Immunity

Generation of a dominant Th1 response driven by IL-12 is essentially required for the expression of protective immunity to fungi. Through the production of the signature cytokine IFN-y and help for opsonizing antibodies, the activation of Th1 cells is instrumental in the optimal activation of phagocytes at sites of infection. Therefore, the failure to deliver activating signals to effector phagocytes may predispose patients to overwhelming infections, limit the therapeutic efficacy of antifungals and antibodies, and favor persistency and or commensalism. Immunological studies in patients with polar forms of paracoccidioidomycosis demonstrate an association between Th1-biased reactivity and the asymptomatic and mild forms of the infection, as opposed to the positive correlation of Th2 responses with the severity of the disease. Not surprisingly, therefore, patients with disseminated infection show defective production of IFN-y and DTH anergy, associated with elevated levels of type 2...

Haemocytes and their Role in the Immune Response


Haemocytes are the immune cells of the insect and are found attached to internal organs of the insect, such as the fat body, trachea, or the digestive system, and circulating freely within the haemolymph. The density of haemocytes circulating in the haemolymph is indicative of infection, with low haemocyte densities being associated with infection and high haemocyte densities associated with healthy insects. This has been explicitly demonstrated by Bergin et al. (2003), where infection of G. mellonella larvae with the yeast Candida albicans resulted in greatly decreased numbers of circulating haemocytes, in contrast to larvae inoculated with the non-pathogenic yeast Saccharomyces cerevisiae, whose haemocyte decreased only slightly in number.

Offensive Virulence Factors

Phospholipases are a heterogeneous group of enzymes which hydrolyze one or more ester bonds in phosphoglycerides. They have an important role in the virulence of bacteria and several pathogenic fungi including Candida species and Cryptococcus neoformans (Ghannoum, 2000). Spectrometric analysis of A. fumigatus filtrates indicated phospholipase A, B, C, and D activities (Birch et al., 1996). The A. fumigatus genome contains six predicted secreted phospholipases (Table 8.1). Of these, two phospholipase B (PLB) genes, AfPLBl and AfPLB3, were cloned and studied. These proteins contain a signal peptide sequence and are secreted enzymes (Shen et al., 2004). None of the A. fumigatus phospholipases were deleted to date and their contribution to virulence remains unknown.

Detailed Immunologic Laboratory Evaluation

Obviously, antigen responses can only be expected if it is documented that the patient has been exposed to the antigen in question. Thus, antigen stimulation tests are usually not useful in early infancy. However, if an older child is known to have received his or her scheduled immunizations, or if candidal infection has been obvious, the response to soluble candidal preparations and vaccine antigens such as tetanus toxoid may be useful. Thus, patients with normal responses to mitogens who fail to respond to candidal preparations may be considered to have chronic mucocutaneous candidiasis rather than a more pervasive T-cell defect, as might be seen in DiGeorge syndrome or HIV infection. In patients with opportunistic infections suggestive of AIDS or positive screening tests for HIV, confirmatory tests, such as Western blot, and quantitation of p24 antigen or viral load should be performed, and absolute CD4 number as well as T-cell function should be assessed as part of the detailed...

Tuning the Adaptive Immune Responses The Instructive Role of DC

Into each others confers unexpected plasticity to the DC system. DC are uniquely adept at decoding the fungus-associated information and translating it in qualitatively different adaptive T-cell immune responses (Romani & Puccetti, 2006a). PRR (such as CR, FcR, C-type lectins (such as DC-SIGN and dectin-1), MR, and TLR determine the functional plasticity of DC in response to fungi and contribute to the discriminative recognition of the different fungal morphotypes. DC (both human and murine) are now known to recognize and internalize a number of fungi, including A. fumigatus, C. albicans, C. neoformans, H. capsulatum, Malassezia furfur, and Saccharomyces cerevisiae and fungi and fungal products may affect DC functioning as well (Romani & Puccetti, 2006a Buentke & Scheynius, 2003). DC are also known to cross-present exogenous fungal antigens through uptake of apoptotic macrophage-associated fungal antigens (Lin et al., 2005). Profiling gene expression on DC by microarray technologies...

The Innate Immunity The Art of Microbe Sensing and Shaping of Specific Immunity

The innate immune system distinguishes self from nonself and activates adaptive immune mechanisms by provision of specific signals. The constitutive mechanisms of defense are present at sites of continuous interaction with fungi and include the barrier function of body surfaces and the mucosal epithelial surfaces of the respiratory, gastrointestinal, and genitourinary tracts. Microbial antagonism (lactobacilli and bifidobacteria have shown efficacy in the biotherapy of candidiasis, The bulwark of the mammalian innate antifungal defense system is built upon effector mechanisms mediated by cells, cellular receptors, and a number of humoral factors (Romani, 2004a Mansour & Levitz, 2002). The professional phagocytes, consisting of polymorphonuclear leukocytes (neutrophils), mononuclear leukocytes (monocytes and macrophages) and DC play an essential role. The antifungal effector functions of phagocytes include fungicidal and growth-inhibiting mechanisms, as well as processes to resist...

Microbial translocation across the bloodCNS barrier

Other pathogens believed to breach the BBB by transcellular passage are L. monocytogenes 120 , Mycobacterium tuberculosis 121 , and fungal pathogens such as Candida albicans 122 and Cryptococcus neoformans 123 . Figure 5 illustrates possible strategies of microbial penetration of blood-CNS barriers 9 .

Absorption Distribution Metabolism and Excretion

Reductions in renal and hepatic function do not alter plasma drug concentrations, and ketoconazole is not removed by hemodialysis or peritoneal dialysis. Penetration into cerebrospinal fluid is negligible, so that ketoconazole is ineffective in the treatment of fungal meningitis. Since only small amounts of active drug appear in the urine, ketoconazole is not effective in the treatment of Candida cystitis.

Oregano Contains Antimicrobial Substances

Antimicrobial activity of oregano has been found at least against such organisms as Bacillus cereus, Acinetobacter baumanii, Aeromonas veronii, bg sobria, Candida albicans, Candida lipolytica, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella enterica subsp., Enterica typhimurium, Salmonella enteritidis, Serratia marcescens, Staphylococcus aureus, Aspergillus ochraceus, A. flavus, A. paraciticus, Clostridium perfringens, Erwinia carotovora, Listeria monocytogenes, Lactobacillus plantarum, Leuconostoc mesenteroides, Debaryomyces hansenii, Hansenula anomala, Kloeckera apiculata, Lodderomyces elongiporus, Rhodotorula rubra, Saccharomyces cerevisiae, Torulopsis glabrata.

Development Of Haustorial System

Mistletoe embryos germinate whilst still in the fruit, but are unable to break through the tough exocarp without help. In nature, birds such as blackcap (Sylvia atricapilla) and mistletoe thrush (Turdus viscivorus) remove the seed from the fruit, more or less effectively getting it in contact with the branch of a host (Grazi, 1986). Apart from mucous polysaccharides which in time are washed out, the mesocarp attached to the endocarp contains glutinous substances which firmly attach the seed to the host bark as they dry. After a period of winter rest induced by cold temperatures, the embryos begin to grow in April by elongating the hypocotyl. Mainly negatively phototropic and if necessary also negatively geotropic growth (Tubeuf, 1923) directs the tip of the hypocotyl towards the host bark. The epidermal cells of the hypocotyl's tip secrete a viscous fluid which enables close contact with the bark and helps to affix the embryo directly to the host (Loffler, 1923).

Pathophysiology of local complications of severe acute pancreatitis

Pancreatic abscess consists of a collection of pus, enclosed by inflammatory walls, resulting from liquefaction of necrotic areas inside or outside the pancreas that have become secondarily infected. Over 50 per cent are polymicrobial with a predominance of enteric bacteria. Candida albicans is often cultured in those previously treated with broad-spectrum antibiotics. In contrast with infected pancreatic necrosis, pancreatic abscess occurs when the active phase of pancreatitis is over and it tends to present with a more indolent process. Remote complications are less frequent, mortality is lower, and sometimes a state of relative well being interplays between the toxemic phase and the clinical emergence of abdominal sepsis.

Immunologic Screening Tests

More rare deficiencies involving other arms of the immune system can also be identified and characterized at this level of testing. In patients suspected of defects in T-cell-mediated immunity, the overall functional activity of T cells is best assessed by determining the patient's ability to mount cutaneous delayed hypersensitivity reactions to recall antigens such as candida, mumps, or tetanus toxoid (3.7.,5.C). Obviously, delayed hypersensitivity skin tests have little meaning in children younger than 2 years of age, who may not be adequately immunized with the antigens in question. Patients who have infections suggestive of defects in T-cell-mediated immunity should also undergo HIV screening.

Linear Plasmids in Yeasts

Yeast linear plasmids, originally detected in K. lactis (Gunge et al. 1981), are known to occur in a panoply of ascomycetous species belonging to different genera (such as Pichia, Candida, Debaryomyces, Saccharomycopsis, Schwanniomyces, Botryoascus) and also in the basidiomycetous representative Trichosporon (see Table 2 Kitada and Hishinuma 1987 Ligon et al. 1989 Worsham and Bolen 1990 Hayman and Bolen 1991 Bolen et al. 1992 Cong et al. 1994 Fukuhara 1995 Chen et al. 2000). A systematic screening among isolates deposited in the CBS-type culture collection revealed linear plasmids in 1.8 of the strains analyzed (Fukuhara 1995). At first sight compared to filamentous fungi few specimens seemed to harbor such genetic elements however, plasmid occurrence in isolates of the same species is remarkably frequent, e.g., 16 for the pGKL system in K. lactis and 54 for pTP1 in Trichosporon pullulans (see also Table 2). The latter is so far the only basid-iomycetous yeast species known to harbor...

Physical examination

Candidal vaginitis most often causes a nonmalodorous, thick, adherent, white vaginal discharge that appears cottage cheese-like. E. The normal pH level is not usually altered with candidal vaginitis. Microscopic examination of vaginal discharge diluted with saline (wet-mount) and 10 KOH preparations will reveal hyphal forms or budding yeast cells. Some yeast infections are not detected by microscopy because there are relatively few numbers of organisms. F. Confirmation of candidal vaginitis by culture is not recommended. Candida on Pap smear is not a sensitive finding because the yeast is a constituent of the normal vaginal flora.

Longterm control medications 1 Corticosteroids

Glucocorticoids provide anti-inflammatory effects and reduce bronchial hyperactivity. Inhaled corticosteroids are first-line agents in patients who require daily asthma therapy. No specific inhaled corticosteroid preparation is superior to another. Primary adverse effects of these medications are cough, oral thrush and hoarseness. In high doses, a potential exists for significant systemic absorption. Patients with severe persistent asthma may require daily systemic steroid therapy when other medications have failed.

The appearance of the skin and mucous membranes may identify anaemia, jaundice, cyanosis, or carbon monoxide poisoning. Bruising over the scalp or mastoids, or the presence of blood in the external auditory meatus or nostrils, raises the possibility of basal skull fracture, and bruising elsewhere in the body raises the question of trauma. An exanthem may indicate the presence of a viral infection causing meningoencephalitis or of meningococcal septicaemia, or raise the question of haemorrhagic disease. Hyperpigmentation raises the possibility of Addison's disease. Bullous skin lesions are frequently seen in barbiturate intoxication. Kaposi's sarcoma, anogenital herpetic lesions, or oral candidiasis would raise the question of the acquired immune deficiency syndrome (AIDS) with a consequent plethora of possible central nervous system disease.
