Last, perform a catalase test (if the organism is not growing on MAC or EMB), or a commercial identification kit system (if the organism is growing on MAC or EMB).
After incubation, the organism is identified as an enterococcus on the basis of morphology of cultures and a negative catalase test and if esculin hydrolysis and PYR reaction (pyrrolidonyl-[beta]-naphthylamide hydrolysis) are positive.
