Gram-negative coccobacilli. Non-motile. Non-spore-forming.
Colonies on bovine agar are non-haemolytic, regular and circular, slightly raised and
greyish with entire margins. Pigment is not formed. The colonies are 0.5-1.5mm in
diameter after 24h of aerobic incubation at 37 ºC. The colonies have a buttery
consistency and are easily removed from the agar surface. No pigment production.
No growth on KCN. V- and X-factors are not required for growth. No growth on
MacConkey agar.
