This study evaluates a novel assay for detecting rifampin resistance in clinical Mycobacterium ulcerans isolates. Although highly susceptible for PCR inhibitors in 50% of the samples tested, the assay was 100% M. ulcerans specific and yielded >98% analyzable sequences with a lower limit of detection of 100 to 200 copies of the target sequence.
本研究评估了一种用于检测临床溃疡分枝杆菌分离株中利福平耐药性的新检测方法。尽管在50%的测试样本中对PCR抑制剂高度敏感,但该检测方法对溃疡分枝杆菌具有100%的特异性,可产生>98%的可分析序列,检测下限为目标序列的100至200个拷贝。
