Answer

As in animals, the human mouth is contaminated with multiple organisms; therefore, any human-bite wound necessitates early recognition and management to avoid complications and infection. Common culprits include aerobic organisms (eg, streptococci, S aureus, Eikenella corrodens), as well as anaerobic organisms (eg, Fusobacterium, Peptostreptococcus, Prevotella, Porphyromonas). [2]

The IDSA recommends parenteral ampicillin-sulbactam or cefoxitin therapy in patients with human-bite wounds, because E corrodens is resistant to first-generation cephalosporins, macrolides, clindamycin, and aminoglycosides. [2]
