Pasteurellosis

Pasteurellosis is an infection with a species of the bacterial genus Pasteurella, which is found in humans and other animals.

Pasteurella multocida (subspecies P. m. septica and P. m. multocida) is carried in the mouth and respiratory tract of various animals, including pigs. 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.
