Animal Bites

Dog bites account for approximately 80% of all animal bites requiring medical attention, in which 85% are provoked attacks. Most dog bites occur on the distal extremities, but children tend to sustain facial bites. Patients who present for medical attention are often concerned about the care of disfiguring wounds or the need for appropriate vaccination (i.e., tetanus, rabies). However, up to 30% of medically treated wounds may become infected. These wounds are often contaminated with multiple strains of aerobic and anaerobic bacteria. Local signs of infection with erythema, edema, pain, and purulent drainage are common with animal bite wounds.

Although the most frequently isolated pathogen related to dog and cat bite wounds is Pasteurella multocida, the array of potential organisms is much greater. Anaerobes such as Bacteroides tectum, Prevotella spp., fusobacteria, and pepto-streptococci can be isolated from animal bite wounds 75% of the time, mostly from wounds with abscess formation. Capnocytophaga canimorsus has also been associated with fatal infection from fulminant sepsis in asplenic patients. Wounds inflicted by cats are often scratches or tiny punctures located on the extremity and are likely to become infected and lead to abscess formation.

In the United States, venomous snakes bite approximately 8000 people yearly. Envenomation in such snakebites account for the majority of morbidity and mortality associated with such bites. However, infection of soft tissue structures may also occur as a result of oral flora from the snake, which tends to be fecal in nature because live prey usually defecate in the snake's mouth with their ingestion.
