Cutibacterium acnes is a skin commensal which is most often regarded as a contaminant when detected on blood cultures. In rare instances, it may be the causative pathogen in severe systemic illnesses. Subacute endocarditis, especially of prosthetic valves and devices, is an important grave pathology caused by Cutibacterium acnes. Herein we report two cases of prosthetic valve endocarditis with varied presentations as valve dehiscence with a "rocking" prosthetic valve apparatus in one encounter and as a septic embolic stroke in the second encounter. Although a rare cause of endocarditis, it becomes an especially important entity in patients with prosthetic devices and should be high in the list of differentials.
痤疮丙酸杆菌是一种皮肤共生菌，在血培养中检测到时通常被视为污染物。在极少数情况下，它可能是严重全身性疾病的致病病原体。亚急性心内膜炎，尤其是人工瓣膜和器械相关的心内膜炎，是由痤疮丙酸杆菌引起的一种重要的严重病理学情况。在此我们报告两例人工瓣膜心内膜炎病例，表现各异，一例表现为人工瓣膜装置“摇摆”导致瓣膜裂开，另一例表现为脓毒性栓塞性中风。尽管它是心内膜炎的罕见病因，但在有植入器械的患者中它成为一个特别重要的疾病，在鉴别诊断清单中应列为重点考虑对象。
