pseudotuberculosis

Irregularly  staining slender rods, often clubbed  and metachromatic granules are
present.
Small, thin, yellowish or grayish white serrate colonies on nutrient agar. Broth is turbid
with sediment, no pellicle is produced. No hemolysis. CAMP reaction (with a beta-
hemolysin-producing strain of
Staphylococcus aureus) is negative. Aerobically
growing (best) and facultatively anaerobic.
It's a frequent commensal in mice, rats and voles, which may develop extensive pseudotuberculous lesions if they are
immunocompromised.
Voles (rodents) may develop extensive pseudotuberculous lesions if they are immunocompromised.
