Rapidly growing non-tuberculous mycobacteria (RGM) are usually detected in blood cultures after 4-5 days of incubation, so it is important to differentiate RGM from contamination of commensal organisms on human skin. We report an unusual case of Mycobacterium mageritense bacteremia and infection of an implantable cardioverter defibrillator originally misidentified as Corynebacterium spp. or Nocardia spp. in gram-stained smears. 16S rRNA gene sequencing had utility in the definitive identification of isolates. We should be aware that RGM infection may exist in repeated implantable device infections.
快速生长的非结核分枝杆菌（RGM）通常在培养4-5天后在血培养中被检测到，因此将RGM与人类皮肤上共生生物的污染区分开来很重要。我们报告了一例不寻常的马格里滕斯分枝杆菌菌血症病例，以及一例最初在革兰氏染色涂片中被误鉴定为棒状杆菌属或诺卡氏菌属的植入式心脏复律除颤器感染病例。16S rRNA基因测序在分离株的最终鉴定中具有实用价值。我们应该意识到，RGM感染可能存在于反复的植入式设备感染中。
