Spec. Char.: E. faecalis can grow in the presence of bile salts.
Special Media:
Enterococcus faecalis  Enterococcus faecalis  
E. faecalis can be cultivated on purple agar and ferments lactose under acid production (see Fig. 124:3). Slanetz and Bartley medium is used for enumeration of bacteria within the genus Enterococcus (see Fig. 124:4).
Disease:Opportunistic infections
Hosts: Different animal species

Taxonomy/phylogeny:
 
About 50 species have been described within the genus Streptococcus. Many species within the genus Enterococcus have earlier been classified as streptococci and, thus, they are closely related.E. faecalis and E. faecium as well as E. avium are rather closely related.
Comment:E. faecalis is type species of the genus. Colonize the intestine and can transfer antibiotic resistance to more pathogenic species. Some strains are used as probioticum.
