Pasteurellosis or Pasteurella infection[1] is an infection with a species of the bacterial genus Pasteurella,[2] which is found in humans and other animals.As the infection is usually transmitted into humans through animal bites, antibiotics usually are effective against the infection.[3]


The several forms of the infection are as follows:skin disease, pneumonia disease and sepsis; other locations are possible, such as meningitis, and acute endocarditis, but are very rare.[4][5][3]


The symptoms of Pasteurellosis can manifest as: swelling, erythema, tenderness, and purulent drainage.[3] Among the possible complications are: abscesses, and osteomyelitis.[3]


Pasteurella multocida is a Gram-negative, nonmotile, penicillin-sensitive coccobacillus of the family Pasteurellaceae, and the etiology of Pasteurellosis.[3]


Diagnosis can be made with the isolation of Pasteurella multocida in a normally sterile site from (blood, pus, or cerebrospinal fluid).[6]

Differential diagnosis

The differential diagnosis of Pasteurellosis is as follows:Staphylococcus aureus, Rabies lyssavirus and Bartonella henselae.[3]


Pasteurellosis is usually treated with high-dose penicillin if severe. Either tetracycline or chloramphenicol provides an alternative in beta-lactam-intolerant patients, however, it is most important to treat the wound.[6][3]


In Australia, the incidence of Pasteurella spp. infections rose from 1 (point) 5 per 100 thousand population in 2000 to 11 (point) 4 per 100 thousand population in 2021.[7]


Pasteurella multocida was first found in 1878 in cholera-infected birds. However, it was not isolated until 1880, by Louis Pasteur, in whose honor Pasteurella is named.[8]
