BACKGROUND AND OBJECTIVES: Endocarditis is a rare and serious complication of human brucellosis. The diagnosis is suspected in cases of endocarditis without response to conservative antibiotic treatment and it is confirmed with enzyme-linked immunosorbent assay (ELISA) test, titers being higher than 1:160. The treatment is usually a surgery, followed with antibiotics for long period of time. Some cases can be cured with antibiotic treatment only, with antibiotics such as doxiciclin, rifampicin, ciprofloxacin, gentamicin and tetracycline. We present a case report of a patient with brucellose endocarditis. CASE REPORT: Fifty one year old male patient, a farmer, was admitted with clinical history of fever and weight loss. Echocardiography showed thickening and vegetation on the aortic valve and blood culture was positive for Staphylococcus epidermidis. The treatment with crystal penicillin and garamycin was initiated with no improval during three weeks. Endocarditis caused by human brucellosis was suspected and a new treatment with rifampicin and ciprofloxacin, associated with vancomycin because of the first blood culture, was initiated. Agglutination sorology was positive for brucellosis, with titers of 1:360. The patient got better with new treatment and was dismissed from the intensive care unit clinically stable, taking ciprofloxacin and gentamicin. CONCLUSIONS: Endocarditis caused by human brucellosis is rare; however it should always be considered when conservative antibiotic treatment fails, especially in patients that have contact with animals and dairy products.
