2019-11-01 · Enterococcus faecalis is a ubiquitous intestinal symbiont and common early colonizer of the neonatal gut. Although colonization with E. faecalis has been previously associated with decreased pathology of necrotizing enterocolitis (NEC), these bacteria have been also implicated as opportunistic pathogens. Here we characterized 21 strains of E. faecalis, naturally occurring in 4-day-old rats

They appear as Gram-positive cocci in pairs and short chains on Gram stain. Colony morphology is small, gray, and γ-hemolytic. E. faecalis and E. faecium are bile esculin Colonies of Enterococcus faecalis cultivated on Columbia agar with 5% defibrinated sheep blood, 24 hours in an aerobic atmosphere, 37°C. E.faecalis typically exhibits gamma-hemolysis on sheep's blood agar, but some strains are alfa-hemolytic or even beta-hemolytic (a plasmid-encoded hemolysin, called the cytolysin).

E. faecalis is a close relative of E. faecium and its genome has been sequenced and analyzed. The sequencing of a vacomycin resistant E. faecalis strain, Enterococcus facalis V583, revealed 1 circular chromosome and 3 plasmids. The chromosome consists of 3218031 base pairs and each plasmid, pTEF1, pTEF2, pTEF3, consists of 66320, 57660, and Formerly known as Streptococcus faecalis and Streptococcus faecium (1).
