Mammalian Bites: Mammalian Bites - pathophysiology
(The 5-Minute Pediatric Consult)

Animal bites:

• Crush-and-tear injuries can result from dog maulings, sometimes involving bone.
• Cat bites are generally puncture-type wounds, penetrating deeper and carrying a higher risk of infection.
• Human bites generally only violate skin, although penetration into joint and tendon sheath spaces can occur (especially bites overlying the metacarpal-phalangeal areas).
• Reports of rates of infectious complications have yielded varying results. Early studies report that infection occurs in 3–18% of dog bites, 28–80% of cat bites, and 15–20% of human bites. Studies that are more recent have suggested an incidence of infection after dog and cat bites to be closer to 2–3%.
• Bacteriologic analysis of infected animal and human wounds demonstrate polymicrobial cause, most commonly mixed aerobic and anaerobic species. Pasteurella species are the most frequent isolates from both dog bites (Pasteurella canis) and cat bites (Pasteurella multocida and Pasteurella septica).
• Common anaerobes include Fusobacterium, bacterioids, Porphyromonas, and Prevotella.
• For infected human bites, bacterial isolates include Streptococcus anginosus, Staphylococcus aureus, Eikenella corrodens, and Fusobacterium and Prevotella species.
