Comparative microbial genomics had its beginning with the evaluation of differences and similarities in distantly related species, including an analysis of the minimal gene set essential to sustaining a functional microbe in accord with its environmental niche [1]. However, with the completion of many new genomes, inter- and intraspecies comparisons of genomes became possible. Such is the case with the streptococci, including the genome sequences of 11 different species, with multiple strains of several species.

This chapter will provide an overview of the present state of genome biology of each of the species, with a following section on bacteriophages unique to the streptococci. These organisms were serologically differentiated from each other on the basis of the major carbohydrate found in the cell wall by Rebecca Lance-field [2], and hence the organisms were designated into serological groups. More recently, Kawamura et al. [3] divided the genus Streptococcus into six major groups based on their 16S rRNA sequences: i.e., the pyogenic, mitis, bovis, salivarius, anginosus, and mutans groups. Excellent recent reviews of the biology, genetics, and host response to all the streptococcal species can be found in Fischetti et al.'s Gram-Positive Pathogens [4].
