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 positive, and can grow in 6.5% NaCl. While there are over 15 species of the Enterococcus genus, 80-90% of clinical isolates are E. faecalis (8). Enterococci typically form short chains or are arranged in pairs. However, under certain growth conditions, they elongate and appear cocobacillary. In general, Enterococci are alpha-hemolytic.

appear as smooth, cream or white colonies with entire edges. E. faecalis are non-hemolytic on sheep blood agars but are beta-hemolytic on media containing rabbit, horse and human blood. Enterococcus gallolyticus (previously known as Streptococcus bovis) can cause bacteremia and is associated with colon cancer.

Cultivation 24 hours, 37°C in an aerobic atmosphere. The optimum time for identification of different colony morphotypes was 72 h. Variations in enterococcal colony morphology on HBA plates at 24 (A), 48 (B), and 72 (C) h of incubation in air at 37 ° Enterococcus faecalis was grown under anaerobic conditions in chemostat cultures on energy sources with different degress of reduction (i.e. mannitol, glucose, pyruvate) at various culture pH values.

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.
