如何早期发现非结核分枝杆菌感染？
大家都知道，早诊断，早治疗可以缩短非结核分枝杆菌的病程，但是如何能早期发现非结核分枝杆菌感染呢？？？对于早发现，我们院感人能做些什么呢？

Abstract
AIMS: To accelerate the identification and differentiation of clinically relevant nontuberculous mycobacteria (NTM) with two sets of multiplex PCR (mPCR) targeting the 16S-23S rRNA internal transcribed spacer (ITS) region for timely patient management.
METHODS AND RESULTS: Two mPCR assays were developed: Slow-Growers (SG) mPCR was used for the detection of slow-growing mycobacteria, which included Mycobacterium avium complex, Mycobacterium kansasii, Mycobacterium gordonae and Mycobacterium xenopi whilst the other mPCR assay labelled as Fast-Growers (FG) mPCR was used for the detection of Mycobacterium fortuitum complex, Mycobacterium abscessus and Mycobacterium chelonae. In these assays, a common forward primer based on a conserved section of the 16S rRNA region was used in conjunction with species-specific reverse primers. The mPCRs were tested against 247 clinical mycobacterial isolates and demonstrated 100% specificity and sensitivity. Identification of the mycobacterial species was also validated by DNA sequencing of the 16S-23S ITS region and when further confirmation was needed, hsp65 sequencing was performed.
CONCLUSIONS: The mPCR assays could be a potentially useful diagnostic tool for the rapid and accurate identification of clinically relevant NTM.
SIGNIFICANCE AND IMPACT OF THE STUDY: In this study, we looked at the frequency of hospital isolated NTM over the last 5 years (2005-2010), and an mPCR targeting the ITS region was developed for NTM species that appeared to be more prevalent in the context of Singapore.
我们应该认识他，了解他，知道如何预防和控制他的传播。
致病的机制是什么？临床表现是什么？当出现暴发的时候能够做什么？如何避免交叉感染？分布是什么，时间，地区，人群？危险因素？高危人群？
我想这些问题是值得关注的。

我是对这种菌出现时我们该做什么，泛指！
我们应该如何识别及返防，希望老师给更好的建议
鉴定应该不是问题，只是很多时候症状不典型，像区分并不容易吧。
不过这几年大家对NTM 的重视程度明显提高了
