pairs. Non-motile.

Colonies on bovine-blood agar are are non-haemolytic, greyish, non-transparent ,
smooth and shiny, circular, slightly raised with entire margin and 1-2 mm in diameter
after 24 h at 37 ºC. Adherence to the agar is absent and the consistency of the
colonies is unguent-like. Facultative anaerobic or microaerophilic. Pigment is not
formed. No V-factor requirement. Growth on MacConkey is positive.
