Enterococcus

''Enterococcus'' is a large genus of lactic acid bacteria of the phylum Firmicutes. Enterococci are Gram-positive cocci that often occur in pairs (diplococci) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. Two species are common commensal organisms in the intestines of humans: ''E. faecalis'' (90-95%) and ''E. faecium'' (5-10%). Rare clusters of infections occur with other species, including ''E. casseliflavus'', ''E. gallinarum'', and ''E. raffinosus''.〔
== Physiology and classification ==
Enterococci are facultative anaerobic organisms, ''i.e.'', they are capable of cellular respiration in both oxygen-rich and oxygen-poor environments. Though they are not capable of forming spores, enterococci are tolerant of a wide range of environmental conditions: extreme temperature (10-45°C), pH (4.5-10.0) and high sodium chloride concentrations.
Enterococci typically exhibit gamma-hemolysis on sheep's blood agar.
