Mycobacterium tuberculosis Beijing genotype strains are rapidly disseminating, frequently hypervirulent, and multidrug resistant. Here, we describe a method for their rapid detection by real-time PCR that targets the specific IS6110 insertion in the dnaA-dnaN genome region. The method was evaluated with a geographically and genetically diverse collection representing areas in East Asia and the former Soviet Union in which the Beijing genotype is endemic and epidemic (i.e., major foci of its global propagation) and with clinical specimens.
结核分枝杆菌北京基因型菌株正在迅速传播,通常具有高毒力且耐多药。在此,我们描述了一种通过实时PCR快速检测它们的方法,该方法靶向dnaA-dnaN基因组区域中的特定IS6110插入序列。我们使用了一个在地理和遗传上具有多样性的样本集对该方法进行评估,该样本集代表了东亚和前苏联地区,这些地区是北京基因型地方性流行和流行性的区域(即其全球传播的主要疫源地),同时还使用了临床标本进行评估。
