What bacteria are typically associated with cat bites?

The bacteria typically associated with cat bites include Pasteurella multocida and several anaerobes. Pasteurella multocida is a Gram-negative bacterium that is found in the oral cavity of cats and can lead to infections following bites or scratches. The organism is known for causing cellulitis and more serious infections, particularly in individuals with compromised immune systems.

Anaerobic bacteria are also prominent in cat bite infections due to the nature of the human mouth flora, which includes various anaerobic species. These bacteria can contribute to the polymicrobial nature of the infections that arise from animal bites. The combined presence of Pasteurella multocida and anaerobes helps explain the typical infectious complications seen in patients who suffer from cat bites, including abscess formation and more severe systemic infections if not treated promptly and appropriately.

Capnocytophaga canimorsus is more commonly associated with dog bites rather than cat bites, while Eikenella corrodens is typically linked to human bites. Staphylococcus epidermidis, a common skin commensal, is less likely to be the primary pathogen involved in cat bites. Therefore, focusing on Pasteurella multocida and anaerobes provides a correct understanding of the bacterial profile associated with cat
