Answer

Infectious complications occur in approximately 15-20% of dog-related bites and more than 50% of cat-related ones. Following a bite, a rapidly progressive cellulitis may develop; deeper structures, including tendons, joints, and bones, can become affected, especially in cat-related injuries. Dissemination can occur.

Degenerative joint disease, rheumatoid arthritis, and prosthetic joints have been associated with the development of P multocida septic arthritis. [21]

Chronic obstructive pulmonary disease is a risk factor for P multocida respiratory tract infection, [22] which carries a mortality rate of approximately 30%. Diabetes mellitus [23] and liver dysfunction [24] are predisposing conditions associated with pasteurellosis and associated bacteremia.

P multocida infections during pregnancy and in utero transmission have also been reported. [25, 26, 27]
