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.  
Nonhemolytic 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.
