Enterococcus is a large genus of lactic acid bacteria of the phylum Bacillota.Enterococci are Gram-positive cocci that often occur in pairs or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [2]
The Enterococcaceae are a family of Gram-positive bacteria placed in the order Lactobacillales. [1] Representative genera include Enterococcus, Melissococcus, Pilibacter, Tetragenococcus, and Vagococcus. In this family are some important lactic acid bacteria which produce lactic acid as the major metabolic end product. [1]

Prior to 1984, enterococci were members of the genus Streptococcus; thus, E. faecalis was known as Streptococcus faecalis. [29] In 2013, a combination of cold denaturation and NMR spectroscopy was used to show detailed insights into the unfolding of the E. faecalis homodimeric repressor protein CylR2. [30]

Similar to other members of the genus, E. casseliflavus is able to hydrolyze esculin. This organism reacts with Lancefield group D antisera. E. casseliflavus shares many phenotypic traits with the more frequently encountered E. faecium. However, additional biochemical tests can be used to separate the two organisms.
Enterococcus solitarius is a species of the genus Enterococcus. It is gram-positive, catalase-negative, and facultatively anaerobic. It was discovered in 1989 alongside Enterococcus raffinosus and Enterococcus pseudoavium [2] Transfer to Tetragenococcus has been proposed. [3]
Enterococcus faecium has been a leading cause of multi-drug resistant enterococcal infections over Enterococcus faecalis in the United States. Approximately 40% of medical intensive care units reportedly found that the majority, respectively 80% and 90.4%, of device-associated infections (namely, infections due to central lines, urinary drainage catheters, and ventilators) were due to ...
