A total of 250 Corynebacterium diphtheriae isolates from clinical cases and carriers in Russia were assayed by PCR directed at the A subunit of the diphtheria toxin gene to distinguish toxigenic from nontoxigenic strains; 170 strains were positive as indicated by the presence of the 248-bp amplicon. The results of this PCR assay were in complete concordance with those of the standard immunoprecipitation assay (Elek), and the PCR assay is a useful tool for rapid identification in clinical laboratories.
运用针对白喉毒素基因A亚基的聚合酶链反应(PCR),对来自俄罗斯临床病例和带菌者的总共250株白喉棒状杆菌分离株进行检测,以区分产毒菌株和非产毒菌株;170株菌株因存在248碱基对的扩增子而呈阳性。该PCR检测结果与标准免疫沉淀检测(Elek)结果完全一致,且PCR检测是临床实验室快速鉴定的有用工具。
