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]
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 ...
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 raffinosus is a bacterial species of the Gram-positive genus Enterococcus, named for its facultative anaerobic metabolism, including the ability to ferment the trisaccharide raffinose. [1] This mesophilic microaerophile has optimal growth at 37°C in Columbia Blood Medium (agar mixture of trypticase soy and brain heart infusion). [2]
Enterococcus gallinarum is a species of Enterococcus. [3] E. gallinarum demonstrates an inherent, low-level resistance to vancomycin.Resistance is due to a chromosomal gene, vanC, which encodes for a terminal D-alanine-D-serine instead of the usual D-alanine-D-alanine in cell wall peptidoglycan precursor proteins. [4]
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]
