A three-year surveillance of non-tuberculous mycobacteria (NTM) in a hospital water distribution system was conducted at a facility located in southern Alberta. NTM was not present in any intake water samples, but was found in 106/183 (58%) of endpoint samples across 15 sites over the study period. Two different species of NTM were identified, Mycobacterium gordonae (88/183) and Mycobacterium avium (34/183); with only one strain of each M. gordonae and M. avium found. Given the sensitive nature of a healthcare facility, attention should be paid to minimize potential impact of NTM from potable water sources on patient health.
在艾伯塔省南部的一家医院设施中，对医院供水系统中的非结核分枝杆菌（NTM）进行了为期三年的监测。在研究期间的 15 个地点的 183 个终点样本中，有 106 个样本（58%）发现了 NTM，但饮用水样本中并未发现 NTM。在研究期间的 15 个地点的 183 个终点样本中，发现了 106 个样本（58%）存在 NTM。鉴定出两种不同的 NTM 物种，戈登分枝杆菌（88/183）和鸟分枝杆菌（34/183）；每种 M. gordonae 和 M. avium 只发现了一个菌株。鉴于医疗机构的敏感性，应注意尽量减少饮用水源中 NTM 对患者健康的潜在影响。
