Gram-positive straight to slightly curved rods, 0.5-2.6 µm, often occurring in angular or
palisade arrangements; metachromatic granules; numerous pili are present.
Nonmotile.
palisade arrangements; metachromatic granules; numerous pili are present.
Nonmotile.
White, semitranslucent colonies on nutrient agar and on serum agar, small, not
readily visible after 24 h at 37 ºC.
In broth, there was slight turbidity, but no pellicle.
Hemolysis is not produced. CAMP reaction is positive. Aerobic, facultative anaerobic.
Can grow at pH 9.0, or at 41.5 ºC. No growth in pH 5.4.

Isolated from cows that showed signs of cystitis and pyelonephritis.
Cells cannot resist 30 min at 56 ºC. Susceptible to kanamycin, erythromycin, neomycin, bacitracin, and terramycin.
