- ❗ Enterococcus flavescens is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Enterococcus.

🧍 The data of Descheemaeker et al. 1997 and the data of several authors suggest that Enterococcus flavescens Pompei et al. 1992 should be considered an Enterococcus casseliflavus [(ex Vaughn et al. 1979) Collins et al. 1984] biovar rather than a separate species.
