Impetigo Cure Diet
A skin infection characterized by pus production is called pyoderma. Pyodermas can result from infection of an insect bite, burn, scrape, or other wound. Sometimes, the injury is so slight that it is not apparent. Impetigo is the most common type of pyoderma (figure 22.5). Impetigo is a superficial skin infection, involving patches of epidermis just beneath the dead, scaly outer layer. Thin-walled Figure 22.5 Impetigo This type of pyoderma is often caused by Streptococcus pyogenes and may result in glomerulonephritis. Figure 22.5 Impetigo This type of pyoderma is often caused by Streptococcus pyogenes and may result in glomerulonephritis. Although Staphylococcus aureus often causes impetigo, many cases, even epidemics, are due to Streptococcus pyogenes. These Gram-positive, chain-forming cocci are -hemolytic (figure 22.6) and are frequently referred to as -hemolytic group A streptococci because their cell walls contain a polysaccharide called group A carbohydrate.

Parents brought their 3-year-old boy to the outpatient clinic because of a facial rash. Today the patient was one of several children sent home from day care because of similar rashes. Physical examination revealed a normal, healthy boy with discrete erythe-matous papular eruptions on his cheeks. There were no vesicles or bullae.

Topical antibiotics are helpful in acne vulgaris and acne rosacea and probably in reducing the frequency of infections related to intravenous catheters. One drug, mupirocin (Bactroban), is effective in treating impetigo contagiosa. Mupirocin binds to bacterial isoleucyl-transfer RNA synthetase and prevents the incorporation of isoleucine into protein sequences. Mupirocin is most effective against gram-positive bacteria. Toxicity is uncommon.
