Question

Quizplus · Accepted Answer

Pasteurella multocida is commonly found in the oral flora of dogs and cats, and can cause severe soft tissue infections such as abscesses when introduced into humans through a bite or scratch. Salmonella typhimurium, Yersinia enterocolitica, Brucella suis, and Francisella tularensis are all pathogens associated with animal exposures, but they are not commonly associated with abscesses from dog and cat bites or scratches.
