Non-motile, Gram-negative, coccoid to pleomorphic rods , singly or grouped in short chains or filamentous forms
Colony morphology resembles that of P. multocida biotype 1, usually reach a
diameter of 1 mm.
Nonhemolytic, V-factor independent, optimum temperature is 36 ºC. Do not grow on
MacConkey agar.

Biotype 1 is recovered mainly from the oral cavities of dogs and from dog-bite wounds in humans; biotype 2 have been isolated from
pneumonia from calves

Have been isolated from the lungs of calves with pneumonia (biotype 2) and from dog-bite wounds in humans (biotype 1).
