What is the antibiotic of choice for an infection from a dog or cat bite?

The antibiotic of choice for an infection resulting from a dog or cat bite is Augmentin. This is due to its broad spectrum of activity, which includes coverage for both aerobic and anaerobic bacteria typically found in human and animal bites. Specifically, Augmentin combines amoxicillin, a penicillin antibiotic, with clavulanate, which helps inhibit beta-lactamase enzymes produced by some bacteria. This combination enhances its effectiveness against resistant organisms that might be present in bite wounds.

In the context of bites, the primary pathogens of concern include Pasteurella multocida, which is commonly found in the mouths of cats and dogs, and other anaerobes. Augmentin effectively addresses these pathogens, making it the recommended first-line treatment.

While other antibiotics listed may have certain uses, they do not offer the same level of protection against the specific bacteria involved in animal bites. For example, clindamycin is useful for specific types of infections but does not provide adequate coverage for all potential organisms in bite wounds. Similarly, ceftriaxone and doxycycline, while effective against certain bacteria, do not have the same comprehensive coverage needed for animal bites where mixed flora is a concern. Hence, Augmentin remains the preferred agent for
