title: Treatment of bacterial endocarditis in a horse.
abstract: Using echocardiography, mitral valve bacterial endocarditis was diagnosed in a yearling Thoroughbred filly with a history of periodic fever and intermittent hind limb lameness. Streptococcus sp were isolated from blood, and the filly was treated with penicillin, resulting in a bacteriologic cure. Severe mitral regurgitation developed secondary to scarring of the valve, which resulted in the filly's death. A poor prognosis usually is indicated in horses with bacterial endocarditis, as bacteriologic cures are infrequent and severe valvular insufficiency often develops.
