Pacemaker infection with Mycobacterium chelonae has not been reported previously. We report the first case of pacemaker lead endocarditis due to M. chelonae, which was successfully treated with multidrug regimen. M. chelonae is regarded as an environmental bacterium and its pathogenicity has been recognised recently. The present case illustrates its ability as a primary invader should not be underestimated, especially in an immunocompetent patient with indwelling devices. Epidemiology and management of this rare cause of culture-negative endocarditis is discussed.
此前尚未有过起搏器感染龟分枝杆菌的报道。我们报告了首例由龟分枝杆菌引起的起搏器导线心内膜炎病例,该病例通过多药联合方案成功治愈。龟分枝杆菌被视为一种环境细菌,其致病性最近才得到认识。本病例表明,不应低估其作为原发性入侵者的能力,尤其是在有植入装置的免疫功能正常的患者中。本文讨论了这种罕见的培养阴性心内膜炎病因的流行病学及治疗方法。
