Description:
Streptococcus (term coined by Viennese surgeon Albert Theodor Billroth (1829-1894) from strepto- "twisted" + Modern Latin coccus "spherical bacterium," from Greek kokkos meaning "berry" ) 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, thus they grow in chains or pairs, hence the name 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.)
