OVERVIEW:
'Streptococcus' is a genus of coccus (spherical) gram-positive bacteria belonging to the phylum Firmicutes and the order Lactobacillales (lactic acid bacteria). Cell division in this genus occurs along a single axis in these bacteria, and thus they grow in chains or pairs, hence the name—from Greek στρεπτÃÅ’ς streptos, meaning easily bent or twisted, like a chain (twisted chain). (Contrast this with staphylococci, which divide along multiple axes and generate grape-like clusters of cells.) Most are oxidase-negative and catalase-negative, and many are facultative anaerobes. In 1984, many bacteria formerly considered Streptococcus were separated out into the genera Enterococcus and Lactococcus. Currently, over 50 species are recognised in this genus. Identified as constituent of skin microbiome. [PMC2746716]
This genus contains microbial species that can reside in the human gastrointestinal tract. [PMC 4262072]
