Pasteurella hemorrhagic infection

Pasleurella is a small, Gram-negative bacillus that is widely found in the respiratory and intestinal tracts of domestic and wild animals. It can develop when the host's resistance decreases. Under normal circumstances, there is no such bacteria in the human body. Most patients develop disease after being scratched or bitten by cats, dogs, and other animals, causing diseases mainly involving the skin. Skin lesions are related to the scope and depth of the bite. The swelling around the initial wound is red and swelling, and the ulcer rapidly expands. The gray-yellow bloody pus is discharged from one or more sinuses. Periostitis and synovitis. Based on medical history, the laboratory isolated a slow-growing, Gram-negative bacilli that can be confirmed. Sensitive to penicillin, ampicillin (ampicillin) and tetracycline.
