Abstract:

This article reports a case of infective endocarditis caused by Corynebacterium striatum and reviews relevant literature. The patient was a 52-year-old male diagnosed with infective endocarditis, from whom Corynebacterium striatum was isolated multiple times from peripheral blood cultures. Following a detailed clinical and laboratory evaluation, a definitive diagnosis of infective endocarditis due to Corynebacterium striatum was made. During treatment, the patient received a combined antibiotic regimen of meropenem and vancomycin, resulting in a favorable outcome. This article emphasizes that Corynebacterium striatum, as an opportunistic pathogen, is increasingly associated with infections in immunocompromised individuals (those with prolonged use of antibiotics, long-term hemodialysis, organ transplantation, interventional procedures such as catheterization, diabetes, and malignancies), and this should alert clinicians to its rising incidence.

摘要：

本文报道1例纹带棒状杆菌引起的感染性心内膜炎病例并进行相关文献复习。患者52岁，男性，诊断为感染性心内膜炎，多套外周血培养均分离出纹带棒状杆菌。经过详细的临床和实验室评估，最终确诊为纹带棒状杆菌引起感染性心内膜炎。患者接受美罗培南联合万古霉素抗感染治疗，取得了较好的疗效。本文着重强调，纹带棒状杆菌作为条件致病菌，在免疫力低下人群（长期使用抗菌药物、长期血液透析、器官移植、置管等介入性操作、糖尿病、恶性肿瘤）中感染率越来越高，应该引起临床的足够重视。
