Gram-positive diptheroidal rods, arranged in clusters or V or Y forms; coccoid elements
may occur.
may occur.
Grown in Todd-Hewitt broth (Oxoid) supplemented with 5% horse serum at 37 ºC.
Facultative anaerobic. Colonies are flat with outrunning edges, especially after
anaerobic incubation on horse blood agar. Non-haemolytic.
