A 24-year-old man presents with cellulitis two days after he is bitten by his cat. What is the most likely dominant organism involved in the infection?
Pasteurella multocida is a dominant organism in the cat's mouth. Choice A, Baonella, is the causative agent of cat scratch fever and is less common in bites. Choice B, Calymmatobacterium, causes a sexually transmitted infection, and Toxoplasma (choice D) is associated with cats but transmitted by their faeces, not bites.
