Gram-negative, rod-shaped cells. Bipolar staining is not common. Non-motile.
Colonies are non-hemolytic and non-pigmented. A few isolates require NAD (V-factor)
for growth. Growth on MacConkey is variable. On blood agar colonies are 1.6-2.0 mm
in diameter after 48 hours, smooth, grayish translucent, with a characteristic odor.
The type strain cannot grow with KCN.

Bacteria is present in the nasopharynx of rats, mice, hamsters; it occurs in the mouth and throat of healthy dogs and cats.
Low experimental pathogenicity.
Causes enzootic disease of mice, rabbits and other laboratory rodents (respiratory infections and abscesses).
Wound infections (dog or cat bites), meningitis, endocarditis, pneumonia, arthritis, osteomyelitis, bacteremia and peritonitis in humans.
