Which Pasteurella species is associated with human infections following cat bites?

• A. P. avium
• B. P. canis
• C. P. multocida
• D. P. stomatis

Answer: (C)

Infections from cat bites are classically linked to Pasteurella multocida, a small Gram-negative bacterium that is a common part of the oral flora of cats (and also present in dogs). When a cat bites, this organism is inoculated into tissue and can cause rapid cellulitis and sometimes deeper infections or abscesses. Among Pasteurella species, multocida is the one most frequently implicated in human cat-bite infections. The other species listed are associated with different hosts or contexts and are not the typical cause of cat-bite infections.
