BACKGROUND Streptococcus thoraltensis is a rare cause of human disease. This report describes a patient with infective endocarditis caused by S. thoraltensis and complicated by ischemic stroke. CASE REPORT A 68-year-old man was admitted for a 12-day duration of fever. He had a history of severe aortic valve stenosis, for which he underwent prosthetic valve replacement, and type 2 diabetes mellitus. Echocardiography revealed vegetation attached to the right coronary cusp of the prosthetic aortic valve and rupture of the sinus of Valsalva into the right ventricle. Blood cultures were positive for S. thoraltensis. He experienced an ischemic stroke involving the vegetation of the aortic valve and died of acute heart failure. CONCLUSIONS S. thoraltensis may be considered an emerging pathogen in patients with infective endocarditis.
背景
海洋链球菌是一种罕见的人类疾病病原体。本报告描述了一例由海洋链球菌引起的感染性心内膜炎患者，并发缺血性脑卒中。
病例报告
一名 68 岁男性因发热 12 天入院。他患有严重的主动脉瓣狭窄，曾接受过人工瓣膜置换术和 2 型糖尿病治疗。超声心动图显示，人工主动脉瓣的右冠状动脉瓣上附有赘生物，瓦氏窦破裂并与右心室相通。血培养阳性提示为海洋链球菌。患者发生了累及主动脉瓣赘生物的缺血性脑卒中，并死于急性心力衰竭。
结论
海洋链球菌可被视为感染性心内膜炎患者的一种新兴病原体。
