Chapter 11 Streptococci, staphylococci and micrococci

Streptococci comprise a diverse group of Gram-positive cocci, which continuously undergo taxonomic revision. They are distributed widely in humans and animals, mostly forming part of their normal flora. A few species cause significant human morbidity. The oral streptococci, which include the cariogenic mutans group, are important members of the genus. Another common group of cocci, the staphylococci, live on the skin but are infrequently isolated from the oral cavity and are significant agents of many pyogenic (pus-producing) human infections.
