Pasteurella is a genus of Gram-negative, facultatively anaerobic bacteria.[1][2] Pasteurella species are non-motile and pleomorphic. Most species are catalase-positive and oxidase-positive.[3] Most relevant species include P. multocida , the most frequent human pathogen, P haemolytica non pathogenic for humans, but important in pneumonia in sheep and cattle and in sepsis for lambs. Isolated reports of human infections caused by P. pneumotropica (sepsis, upper respiratory tract infections, animal bite infections) are present in the literature.[4]

Pathogenesis[edit]

See: Pasteurellosis

Many Pasteurella species are zoonotic pathogens, and humans can acquire an infection from domestic pet bites.[5][6] P. multocida is the most frequent causative agent in human Pasteurella infection.[7] Common symptoms of pasteurellosis in humans include swelling, cellulitis, and bloody drainage at the site of the wound. Infections may progress to nearby joints where it can cause swelling and arthritis.

Pasteurella spp. are generally susceptible to the penicillins, tetracycline, chloramphenicol, but resistant to macrolides (erythromycin). Fluoroquinolones are generally active and might be a good alternative in penicillin allergic patients.

Pasteurella occurs in many cats' mouths, a large percentage of dog mouths, and frequently in rabbits. This is in perfectly normal and otherwise healthy animals. The common occurrence of the bacteria is a reason to be medically proactive and defensive (antibacterial treatments are often necessary) if a bite occurs.[8]

In rabbits[edit]

P. multocida is also known to cause morbidity and mortality in rabbits. The predominant syndrome is upper respiratory disease. P. multocida can be endemic among rabbit colonies and is often transmitted through nasal secretions. P. multocida can survive several days in water or moist areas.[9]
