Jawetz, 1950. Species "Incertae Sedis“.
Rod-shaped cells. Bipolar staining is not common.
Colonies are nonhemolytic and V-factor independent. 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.
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 & peritonitis in humans.
