Prevotella bivia Infection of a Horse Bite Wound.

ABSTRACT

Horse bites are common non-fatal injuries in the United States. Infections of horse bite wounds in humans are usually due to bacteria that correspond to the oropharyngeal bacterial flora of horses. We report the novel case of a 25-year-old woman who sustained a horse bite wound that was infected with Prevotella bivia, a Gram-negative, non-pigmented anaerobe. We discuss the epidemiology, bacteriology, and clinical management of horse bites.
