Additionally, the volume incorporates and discusses aspects of pneumococcal, entrococcal, and oral streptococcal disease. The recent resurgence of rheumatic fever, concomitant outbreaks of severe. Streptococci originally designated as S. mutans were isolated from dental caries and from bacterial endocarditis. In contrast to the initially perceived phenotypic homogeneity, subsequent serological, genetic, and biochemical studies showed considerable heterogeneity (Table 1). 16S rRNA data place Streptococcus criceti, Streptococcus dentapri, Streptococcus dentirousetti, Streptococcus. Streptococcus is a diverse genus of Gram-positive bacteria commonly found in multiple locations of their human and animal hosts e.g. the oral cavity and the upper respiratory tract. Many streptococci are commensals thus play a role in colonization resistance of the host. Others, however, are pathogenic and are responsible for a range of invasive and noninvasive diseases with high morbidity and.

Classification and nomenclature. Streptococci are Gram-positive coccus-shaped bacteria that occur in pairs or chains. These species are catalase negative (distinguishing them from Staphylococcus species) and most require enriched media such as blood agar. Traditionally, microbiologists sub-classified these bacteria by examining their appearance on blood agar; three distinctive patterns emerge.

In , species in the genus Streptococcus were divided into three separate genera: Streptococcus, Lactococcus, and Enterococcus (Facklam and Collins, ).). “Fecal streptococci” or “Lancefield’s group D streptococci” associated with the gastrointestinal tract of humans. Streptococcus is a genus of gram-positive coccus (plural cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Firmicutes. Cell division in streptococci occurs along a single axis, so as they grow, they tend to form pairs or chains that may appear bent or twisted.. This differs from staphylococci, which.
