Abstract：
A 74-year-old woman with a history of mitral valve prolapse with mitral regurgitation was transferred to our hospital due to infective endocarditis. Blood culture revealed Abiotrophia defectiva which is known as a nutritional variant streptococcus. Transesophageal echocardiography revealed posterior leaflet (P2) prolapse due to rupture of tendon chordae with severe mitral regurgitation and vegetation on posterior leaflet. Magnetic resonance imaging (MRI) revealed multiple infarction lesions in left temporal lobe and parietal lobe and mycotic aneurysm formation of right middle cerebral artery. Because A. defectiva cannot be cultured on non-supplemented media, their prevalence may be underreported.
UNASSIGNED: A number of causative microorganisms of infective endocarditis have been identified. Streptococci and staphylococci account for 80 % of cases of infective endocarditis. Abiotrophia defectiva does not grow in ordinary growth media and its prevalence may be underreported. It is important to know A. defectiva causes infective endocarditis with mycotic aneurysm formation.

摘要：
一名有二尖瓣脱垂伴二尖瓣反流病史的74岁女性因感染性心内膜炎被转移到我院。血液培养显示出无营养缺陷，被称为营养变异链球菌。经食管超声心动图显示后叶（P2）脱垂，原因是肌腱腱索断裂，二尖瓣严重反流和后叶植被。磁共振成像（MRI）显示左颞叶和顶叶多发梗死灶以及右大脑中动脉的霉菌性动脉瘤形成。因为不能在非补充培养基上培养。他们的患病率可能被低估。
■已鉴定出许多感染性心内膜炎的致病微生物。链球菌和葡萄球菌占感染性心内膜炎病例的80％。在普通的生长培养基中，营养不良性缺陷不会生长，其患病率可能被低估。重要的是要知道A.futectiva引起感染性心内膜炎并形成霉菌性动脉瘤。
