Culture-negative endocarditis: contribution of bartonella infections.
نویسندگان
چکیده
Two cases of bartonella endocarditis are described: one in a 55 year old homeless alcoholic man, caused by Bartonella quintana; the other in a 41 year old male with a history of exposure to cat fleas, caused by B henselae. Serological testing and polymerase chain reaction of the excised valves were used to identify the organisms. False positive serology for chlamydia was detected in one case.

Both cases were accompanied by glomerulonephritis, in one case proven by a kidney biopsy. A nephrotic syndrome may be the first presentation of an endocarditis caused by Bartonella species.
