Bartonella henselae infection is typically associated with cat scratch disease. This microorganism can also lead to culture-negative infective endocarditis in immunocompromised patients. We present a rare case of a previously healthy 65-year-old man with B. henselae-associated endocarditis of a prosthetic aortic root. All blood cultures, as well as cultures of the resected aortic valve vegetations, remained negative. Polymerase chain reaction with specific bacterial primers with DNA sequencing was used to identify B. henselae as the etiologic agent. This was successfully managed by an aortic root re-replacement using a mechanical conduit, reimplantation of coronaries ostia, and antibiotic therapy.
汉赛巴尔通体感染通常与猫抓病相关。这种微生物也可导致免疫功能低下患者发生培养阴性的感染性心内膜炎。我们报告 1 例罕见病例，为先前健康的 65 岁男性，患有假体主动脉根部的汉赛巴尔通体相关性心内膜炎。所有血培养物以及切除的主动脉瓣赘生物培养物均为阴性。采用特定细菌引物聚合酶链反应结合 DNA 测序鉴定汉赛巴尔通体为病原体。通过再次使用机械移植物置换主动脉根部、重新植入冠状动脉开口和抗生素治疗，成功地对此进行了治疗。
