Gram-negative, cocoid to rod cells, bipolar staining, nonmotile.
On blood containing solid media small colonies of about 1 mm in diameter with
graish or semitranslucent appearance are formed. Non-hemolytic, facultatively
aerobic, V-factor independent.
Growth on MacConkey is negative.
Optimum temperature is 36 ºC.
Occurs in the oral cavity or respiratory tract of dogs and cats .
Isolated from wound infections in humans resulting from dog and cat bites.
