RESUMEN
Animal bite wounds and their subsequent infection are relatively common. Incidence rates for dog bites are significantly higher among children aged 0-9 years, especially among boys. Although bite wounds may initially look innocuous, they frequently lead to serious infection with a potential for life-threatening complications. The microbiology of dog bite wounds is usually polymicrobial, typically including anaerobes, Staphylococcus aureus and Pasteurella species. A case is described of a 22-month-old boy who, subsequent to a dog bite over the left maxilla, suffered infection of the dental follicle of the primary maxillary canine with Pasteurella multocida. The infection proved difficult to treat, requiring several attempts at incision and drainage of the abscess together with systemic antibiotics, and resulted in the eventual loss of the tooth.
