Haemorrhagic septic Pasteurella infection

Pasleurella is a small Gram-negative bacterium, which widely exists in the respiratory tract and intestines of domestic and wild animals. It can come on when the resistance of the host decreases. Under normal circumstances, the bacterium does not exist in the human body. Most patients get sick after being scratched and bitten by cats, dogs and other animals, causing diseases mainly involving the skin. The skin lesions are related to the scope and depth of the bite. Initially, the wound is red and swollen, rapidly expands and breaks, and gray yellow bloody pus is discharged from one or more sinuses. In some cases, the edge of the wound is obviously tender. If the wound is deep, it can cause periostitis and synovitis. According to the medical history, the slow growing and gram-negative bacilli isolated in the laboratory can be diagnosed. Sensitive to penicillin, ampicillin (ampicillin) and tetracycline.
