Pasteurella multocida

Wikipedia Abstract

Pasteurella multocida is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus belonging to the Pasteurellaceae family. Strains belonging to the species are currently classified into five serogroups (A, B, D, E, F) based on capsular composition and 16 somatic serovars (1-16). P. multocida is the cause of a range of diseases in mammals and birds, including fowl cholera in poultry, atrophic rhinitis in pigs, and bovine hemorrhagic septicemia in cattle and buffalo. It can also cause a zoonotic infection in humans, which typically is a result of bites or scratches from domestic pets. Many mammals (including domestic cats and dogs) and birds harbor it as part of their normal respiratory microbiota.

Invasive Species

The species Pasteurella multocida includes a heterogeneous group of Gram-negative bacteria that are inhabitants of the upper respiratory tract of many vertebrate hosts, including birds, cattle, swine, cats, dogs and rodents. Members of this species are responsible for a number of infections that normally are secondary to colonisation of the upper respiratory tract, including avian cholera (in waterfowl, chickens and turkeys), respiratory disease and hemorrhagic septicemia in ruminants (cattle, sheep, goats and bufallo), atrophic rhinitis in pigs and snuffles/septicemia in rodents (mice & rabbits). These infections are primarily transmitted by the respiratory route and are associated with crowding and other stressors. P. multocida is also a rare cause of infection in humans that is normally associated with dog or cat bites or scratches. Colonisation and disease causation in a particular host tends to be associated with specific subgroups, suggesting that they may represent lineages adapted to growth and survival in related host species.
