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 stain. 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, and may be transmitted by cat bite.



There are several forms of the infection:

Other locations are possible, like septic arthritis, meningitis and acute endocarditis but are very rare.

Pasteurellosis in animals

P. multocida causes numerous pathological conditions in domestic animals. It often acts together with other infectious agents, like Chlamydiae, Mycoplasmae, viruses. The environmental conditions also play a role like transportation, housing deficiency, and bad weather.

The following diseases are considered caused by P. multocida, alone or associated to other pathogens :


Diagnosis is made with isolation of Pasteurella multocida in a normally sterile site ( blood, pus or CSF).


Pasteurellosis is usually treated with high dose penicillin. Tetracycline and chloramphenicol provides an alternative in beta-lactam intolerant patients.
