Two nested PCRs for the detection of Mycobacterium ulcerans were compared by using a collection of 65 clinical specimens. The first method amplifies the gene coding for 16S rRNA, and the second method amplifies a repetitive DNA sequence. The sensitivities of bacterioscopy, culture, 16S rRNA gene PCR, and repetitive-sequence PCR were 29, 34, 80, and 85%, respectively. Compared to the 16S rRNA gene PCR, the repetitive-sequence PCR was faster, easier to perform, and less expensive.
通过使用65份临床标本的集合，对两种用于检测溃疡分枝杆菌的巢式PCR进行了比较。第一种方法扩增编码16S rRNA的基因，第二种方法扩增重复DNA序列。细菌学检查、培养、16S rRNA基因PCR和重复序列PCR的敏感性分别为29%、34%、80%和85%。与16S rRNA基因PCR相比，重复序列PCR更快、更易于操作且成本更低。
