Pasteurella species are members of the normal flora of the upper respiratory tract and gastrointestinal system of wild and domestic animals. They most frequently lead to cellulitis and subcutaneous abscess, however, they may also cause serious clinical conditions such as osteomyelitis, pneumonia, endocarditis, sepsis and meningitis. Here, a case of acute osteomyelitis due to Pasteurella multocida in a 70 year- old diabetic man who had a history of cat bite on his left hand, was presented in the light of the literature.
