Description is based on a single isolate.
Gram-positive straight to slightly curved rods, some of which exhibit branching.
Non-motile.
Colonies are tiny, irregular, convex, white and adherent to medium. It was cultured on
Columbia agar (Difco) supplemented with 5% horse blood at 37 ºC  in air plus 5%
CO
2. Facultative anaerobic.
Isolated in mixed culture with Corynebacterium genitalium from the vagina of a cocker spaniel dog. Habitat is not known.
Undetermined.
