Gram-negative rods. Non-motile.
Colonies grown on BA are circular, grey, translucent to opaque, convex, entire,
smooth and pinpoint to 1 mm in diameter after 24 h of incubation at 37 ºC. A
very slight green discoloration of the agar may appear when incubated for more than
48 h. Growth occurs in the presence of 10 % CO2, under anaerobic conditions and at
20 ºC, 30 ºC and 42 ºC. No growth occurs on MacConkey agar. X and V factors are not
required.
