Streptococcus is a genus of gram-positive coccus (pl.: cocci) or spherical bacteria that belongs to the family Streptococcaceae, within the order Lactobacillales (lactic acid bacteria), in the phylum Bacillota.[2] 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 divide along multiple axes, thereby generating irregular, grape-like clusters of cells. Most streptococci are oxidase-negative and catalase-negative, and many are facultative anaerobes (capable of growth both aerobically and anaerobically).

The term was coined in 1877 by Viennese surgeon Albert Theodor Billroth (1829–1894),[3] by combining the prefix "strepto-" (from Ancient Greek: στρεπτός, romanized: streptós, lit. 'easily twisted, pliant'[4]), together with the suffix "-coccus" (from Modern Latin: coccus, from Ancient Greek: κόκκος, romanized: kókkos, lit.'grain, seed, berry'.[5]) In 1984, many bacteria formerly grouped in the genus Streptococcus were separated out into the genera Enterococcus and Lactococcus.[6] Currently, over 50 species are recognised in this genus. This genus has been found to be part of the salivary microbiome.[7]
