近几十年来,由非结核分枝杆菌(NTM)引起的感染一直是一个公共卫生问题,并在全球范围内造成了重大的临床和经济负担。感染的诊断是困难和耗时的,此外,由于交叉反应和不完全特异性探针,传统的诊断测试在物种鉴定方面没有足够的辨别能力。然而,随着技术的进步,全基因组测序(WGS)方法已被证明是临床分枝杆菌学实验室常规诊断的重要组成部分。该技术的使用有助于鉴定分枝杆菌新种,以及鉴定编码抗性和毒力因子的基因突变。测序数据还允许追踪由脓肿分枝杆菌复合体和嵌合体引起的全球院内NTM感染暴发。为了突出WGS的实用性,我们总结了近年来关于WGS作为一种适用于临床ntm诱导感染管理工具的科学研究。
Infections caused by non-tuberculous mycobacteria (NTM) have been a public health problem in recent decades and contribute significantly to the clinical and economic burden globally. The diagnosis of infections is difficult and time-consuming and, in addition, the conventional diagnostics tests do not have sufficient discrimination power in species identification due to cross-reactions and not fully specific probes. However, technological advances have been made and the whole genome sequencing (WGS) method has been shown to be an essential part of routine diagnostics in clinical mycobacteriology laboratories. The use of this technology has contributed to the characterization of new species of mycobacteria, as well as the identification of gene mutations encoding resistance and virulence factors. Sequencing data also allowed to track global outbreaks of nosocomial NTM infections caused by M. abscessus complex and M. chimaera. To highlight the utility of WGS, we summarize recent scientific studies on WGS as a tool suitable for the management of NTM-induced infections in clinical practice.
