Gram-negative rods. Non-motile.
Colonies grown on Blood Agar are circular, grey, opaque, raised, entire, smooth, and
pinpoint to 0.5 mm in diameter after 24 h of incubation at 37 ºC. A very slight green
discoloration of the agar is often apparent, particularly around colonies incubated for
48 h or more. Growth occurs in the presence of 10% (v/v) CO2, under anaerobic
conditions and at 20 ºC, 30 ºC and 42 ºC. Neither X nor V factors are required for
growth.
