Enterococcus faecalis colony appearance and morphology on blood agar. Convex, nonhemolytic colonies without pigmentation. Cultivated 24 hours, 37°C.

Enterococcus faecalis (Andrewes and Horder, 1906) Schleifer and Kilpper-Bälz, 1984 Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans and other mammals.

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). FIG. 1. Colony morphologies of E. faecalis wild-type and SCV phe-notypes on CASO blood agar after 24 h of incubation. FIG. 2. PFGE of E. faecalis wild-type and SCV clinical isolates after SmaI restriction. Lanes 1 and 5, 48.5- to 970-kb molecular weight marker (lambda c1857Sam7; Bio-Rad, Germany); lane 2, wild-type Cocci were identified as Enterococcus faecalis by biochemical and molecular methods.
