摘要: 目的 建立多引物检测鼠疫耶尔森菌(鼠疫菌)的PCR(M-PCR)方法。方法 合成4对引物,分别来源于质粒和染色体DNA上F1、plaHmsInv基因,对164株鼠疫菌进行扩增。结果 在164株鼠疫菌中,有152株菌4种基因扩增均阳性,仅云南省12株Hms基因扩增为阴性。结论 采用M-PCR方法检测鼠疫菌DNA具有较好的敏感性、特异性和稳定性,其可作为检测与鉴别鼠疫菌和疫情监测方面快速诊断的方法。

Abstract: Objective To develop a polymerase chain reaction(PCR) method to detect Yersina pestis by multiplex primers(M-PCR).Methods Four pairs of primers,originated from the genes F1(specific capsular antigen fraction 1),pla(palsminogen activator),Hms andInv encoded on the two kinds of 65×106 plasmids and two chromosomal DNA,were designed and 164 strains ofc Y.pestis were amplified with multiplex primers.Results One hundred and fifty-two of 164 strains of(Y.pestis) showed positive in M-PCR.Only 12 strains of them isolated from Yunnan were negative with amplification of the Hms gene.Conclusion M-PCR method showed satisfactory sensitivity,specificity and stability for detecting and identifying Y.pestis DNA and could be used in surveillance and rapid diagnosis for plague.
