Acidification of methyl-alpha-D-glucopyranoside: a useful test to differentiate Enterococcus casseliflavus and Enterococcus gallinarum from Enterococcus faecium species group and from Enterococcus faecalis.
Enterococcus gallinarum and E. casseliflavus are difficult to differentiate from other enterococci, particularly E.faecium. The former two species were found to produce acid from methyl-alpha-D-glucopyranoside in phenol red broth, while E.faecalis strains and strains of the E.faecium species group, including E.faecium, E.durans, E. hirae, and E.mundtii, failed to produce acid from this substrate.
