BACKGROUND: Brucella endocarditis (BE) is a lethal complication of human brucellosis, which is rarely seen and hardly described. METHODS: In the present report, six successfully treated cases of BE involving three native aortic valves, two native mitral-aortic valves, and a mitral bioprosthesis are described. The diagnosis of BE was based on clinical features, high brucella serologic titers, and positive blood cultures. Although the blood cultures were positive in all patients, all the resected valve materials and tissue cultures were negative. The patients received rifampicin, streptomycin, and doxycycline (in 3 patients), rifampicin, tetracycline, and cotrimoxazole (in 2 patients), and rifampicin, doxycycline, and cotrimoxazole (in 1 patient). Infected native valves and bioprosthesis were replaced by mechanical valves. RESULTS: There was no early or late mortality. No recurrent infection developed after management with a combination of antibiotherapy lasting 6 months postoperatively during a mean follow-up of 47 months (range 20 to 84 months). CONCLUSIONS: This report suggests that the combination of valve replacement and antibiotic therapy produces successful results in the treatment of BE.
