Gram-negative coccobacilli. Non-motile. Non-sporulated.
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.
Non-haemolytic on sheep blood agar.
Isolated from human and animal clinical specimens.
Undetermined. Isolated from human clinical specimens (skin, blood, ear pus, vaginal swab) and dog ear.
