Rochalimaea quintana and Rochalimaea henselae are closely related, fastidious, gram-negative rickettsiae. Thus far, the spectrum of human Rochalimaea sp. infections has not included endocarditis. We describe a 50-year-old human immunodeficiency virus-positive man who developed endocarditis caused by R. quintana. DNA relatedness studies, which compared our patient's blood culture isolate with known Rochalimaea species, identified the organism as R. quintana. Our report expands the spectrum of Rochalimaea sp. infections and identifies a new infectious cause of endocarditis.
五日罗卡利马氏体和汉氏罗卡利马氏体是密切相关、苛求、革兰氏阴性立克次氏体。迄今为止,人类罗卡利马氏体属感染谱尚未包括心内膜炎。我们描述了一名50岁的人类免疫缺陷病毒阳性男性,他患上了由五日罗卡利马氏体引起的心内膜炎。通过将我们患者血培养分离菌与已知罗卡利马氏体菌种进行比较的DNA相关性研究,确定该病原体为五日罗卡利马氏体。我们的报告扩展了罗卡利马氏体属感染谱,并确定了一种心内膜炎的新感染病因。
