Gram-negative coccobacilli. Nonmotile. Nonsporulated.
Colonies on TSA after 24 h incubation at 30 ºC are approximately 0.3-0.7 mm in
diameter, circular, convex, smooth and slightly opaque with entire margins. Growth
occurs at 35 ºC but not at 41 ºC. Growth at 37 ºC usually occurs but may be reduced.
