A rather large irregularly staining bacillus, 0.7-3.0 µm. Metachromatic granules are
present. Fimbriae are present. Nonmotile.
Dry, granular, cream to pale yellow colonies on nutrient or blood agar; growth not
improved by blood, but yellow pigment may be more marked. Hemolysis is not
produced. CAMP reaction is positive. Aerobic, facultative anaerobic.
Isolated from cases of cystitis and pyelonephritis in cattle.
Pathogenic, causes pyelitis and cystitis in experimental animals and cattle.
