​Infection Diseases and Microbiology - Cat Bite Fever ( Pasteurella multocida) 
Pasteurella multocida causing  cat bite fever
Gram-negative coccobacilli that are nonmotile and have a bipolar look on stained smears that are stained. Infection caused by P multocida is the most frequent type of infection that can be contracted by a scratch or bite from a dog or cat. The oral flora of animals contains this organism, and the most common way for humans to become infected with it is through direct inoculation.
It is also possible for people to contract respiratory diseases from animals.

After a scratch or bite, the most common finding is cellulitis, which often manifests itself within twenty-four hours after the incident.
 It is not uncommon for patients to experience local problems such as tenosynovitis, osteomyelitis, and septic arthritis. Septicemia, meningitis, and infections of the respiratory tract are examples of consequences that occur far less frequently.

 Some of the virulence factors that are present in P multocida include a capsule, hyaluronidase, and cell wall endotoxin. The inflammation of host cells is the major mechanism that manifests the harmful effect.
 A wide range of antibiotics, such as penicillin, ampicillin, tetracycline, and amoxicillin-clavulanate, are generally successful in treating bacterial infections. It may be necessary to perform debridement or drainage of the wound. To prevent the spread of animal bites, it is necessary to avoid them and properly clean them.
