Old synonym:
Pasteurella species B Mutters et al. 1985.
Cells are coccobacillary to rod shaped. Nonmotile.
Colonies on blood agar, after aerobic incubation for 24 h at 37 ºC, are  circular, slightly
raised and regular with an entire margin 1.5 mm in diameter. The surface is smooth,
shiny and opaque with a greyish tinge.
Do not adhere to the agar. Nonhemolytic.
CAMP-negative. V-factor independent. No growth on MacConkey agar.
Strains were isolated from different animal hosts (dogs, cats, a bat and a ferret), and from human dog-bite wounds or cat scratches.
Later isolates were reported from African hedgehogs (
Atelerix albiventris), banded mongoose (Mungos mungo), Moholi bushbaby
(
Galago moholi) and Varanus albigularis.
Unknown. Possible wound contaminant.
