非结核分枝杆菌感染流行病学与医院感染防控

Epidemiology and prevention of non-tuberculous mycobacteria infection

非结核分枝杆菌（Non—tuberculous mycobacteria，NTM）广泛存在于环境中，长期被视为污染菌或定植菌。近年来，越来越多的资料显示NTM可导致人类疾病，并可引起医院感染与暴发。该文对NTM的流行病学及医院感染防控作个阐述。

Non-tuberculous myeobacteria （NTM） are organisms ubiquitously existing in the environment, which have been considered as contamination or colonization bacteria. In recent years, more and more evidences suggest that NTM can cause human diseases, resulting in nosocomial infection, even outbreaks. The aim of this article intends to introduce the epidemiology and prevention of NTM infection.
