 This is probably Pasteurella multocida, a small gram negative rod, which
stains poorly with the counterstain and may show bipolar staining. It grows
aerobically on various rich media such as tryptone soya agar or blood agar.
Colonies are convex, grey in colour with a strong smell of indole. The
colonies look very much like E. coli but are positive in an oxidase test (E.
coli is negative). It won't grow on media containing bile salts such as
MacConkey agar.

Pasteurella is the most common cause of wound infection  caused by animal
bites. The organism is normally susceptible to many antibiotics including
penicillin/ ampicillin.
