>Enterococcus faecalis is a gram positive cocci occuring normally in chains.
>It is catalase negative.
>It hydrolyzes arginine, is positive for acid formation in mannitol and
>sorbitol broths and negative for acid formation in sorbose broth.
>These reactions will differentiate E.faecalis from the Staph (which are
>catase positive) and
>from most other Strep species.
>Of the other organisms that may share these reactions, E.faecium is
>probably most common
>and may be differentiated by being arabinose positive and pyruvate negative
>(E.faecalis is reversed).
>Other Group II Enterococcus may be differentiated with more elaborate
>biochemical workups
>(refer to the Manual of Clinical Microbiology, ASM, 1995).
>note that "Strep. faecalis" is the previous nomenclature for Enterococcus
>faecalis and that
>your terminology "Strep f" may lead to confusion; i.e. Strep Lancefield
>Group F are very
>different bugs (usually referred to as "S. milleri" group).
