Rationale:
- Infected bite wounds require appropriate antibiotic treatment, which can be guided by culture results.
- Most mammalian bite infections are polymicrobial and are caused by a combination of aerobic and anaerobic bacteria.
- Failure to treat bite wounds appropriately increases the risk of hospitalization.
|
|
Evidence:
- A prospective study of animal bites revealed that a mixture of aerobes and anaerobes caused 63% and 48% of cat and dog bites,
respectively (19).
- The median number of bacteria isolated from an infected human bite is 5, of which 3 are anaerobic (4).
- A study of 14 consecutive admissions for Pasteurella multicoda infections from dog and cat bites revealed that the most common etiologic factor was inappropriate antibiotic treatment (26).
