Pasteurellosis is an infection with a species of the bacteria genus Pasteurella[1] , which is found in humans and animals.
Pasteurella multocida (P. septica) is carried in mouth and respiratory tract of several animals, notably cats. It is a small gram negative bacillus with bipolar staining by Wayson coloration. In animals it can originate fulminant septicaemia ( chicken cholera), but is also a common commensal.
Pasteurellosis in humans is associated with a close animal contact, namely a catbite.

[edit] Types
There are several forms of the infection:
- Cutaneous / subcutaneous disease : this is a septic phlegmon that develops classically in the hand and forearm after cat bite. Inflammatory signs are very rapid to develop, in 1 or 2 hours edema , severe pain and serosanguineous exudate appears. Fever , moderate or very high can be seen alongside with vomiting, headache and diarrhea. Lymphangitis is usual. Complications are possible, in the form of septic arthritis, osteitis or evolution to chronicity.
- Septicaemia : is very rare, but can be as fulminant as septicaemic plague , with high fever, rigors and vomiting followed by shock and coagulopathy.
- Pneumonic disease : is also rare and appears in patients with some chronic pulmonary pathology. it usually presents as billateral consolidating pneumonia , sometimes very severe.
Other locations are possible, like septic arthritis, meningitis and acute endocarditis but are very rare
[edit] Diagnosis
Diagnosis is made with isolation of Pasteurella multocida in a normally sterile site ( blood, pus or CSF).
[edit] Treatment
Pasteurellosis is usually treated with high dose penicillin. Tetracycline and chloramphenicol provides an alternative in beta-lactam intolerant patients.
