Abstract
Mycobacterium chimaera is an environmental non-tuberculous mycobacterium belonging to Mycobacterium avium complex (MAC). It has been widely known to be associated with disseminated infection after cardiac surgery, related to heater-cooler units used during these procedures. Although M. chimaera seems to be a less virulent species compared to M. avium and M. intracellulare among MAC, several cases of M. chimaera lung infections have been reported in settings of chronic obstructive pulmonary disease (COPD), cystic fibrosis, bronchiectasis, malignancy, or immunosuppression. Here, we present an Italian case report in association with newly diagnosed COPD.
奇异分枝杆菌（Mycobacterium chimaera）是一种环境非结核分枝杆菌，属于分枝杆菌复合体（MAC）。众所周知，它与心脏手术后的播散性感染有关，与这些手术中使用的加热器-冷却器装置有关。尽管在 MAC 中，M. Chimaera 与 M. avium 和 M. intracellulare 相比似乎是毒性较弱的一种分枝杆菌，但在慢性阻塞性肺病（COPD）、囊性纤维化、支气管扩张、恶性肿瘤或免疫抑制的情况下，也有多例 M. Chimaera 肺部感染的报道。在此，我们报告了一个意大利病例，该病例与新诊断的慢性阻塞性肺病有关。
