Pasteurellosis

Pasteurella multocida is widespread in the respiratory and intestinal tracts of many domestic and wild animals. Most human infections are caused by bites from cats, dogs or other animals. Its epidemic situation is unclear. The pathogenesis is uncertain. Skin lesions are common in the hands, forearms, and lower limbs. The earliest wounds appeared red and swollen, quickly spread and ulcerated, and discharged yellow bloody pus from the multiple sinus tract. The pain was locally associated with severe pain. When the bite is deep, it can also cause periostitis and osteomyelitis . Diagnosis is based on medical history and isolation of slow-growing Gram-negative microbacilli from pus or sputum. Penicillin and tetracycline have a good effect on this disease.
