摘要: 本研究针对猪伪狂犬病病毒的gE基因序列进行分析比较,设计了一条TaqMan-MGB探针,建立了区别野毒株及基因缺失疫苗株的荧光定量PCR检测方法。结果表明,该方法检测猪伪狂犬病病毒特异性强,能很好的区分猪伪狂犬病病毒与其它病毒。用该方法对83份疑似样本进行检测,与常规PCR检测法符合率达到100%,表明该方法用于检测猪伪狂犬病病毒具有良好的实用性。

Abstract: A pair of specific primers and one TaqMan-MGB probe were designed based on gE gene through comparison and analysis, the FQ-PCR method was successfully constructed which could distinguish wild strain and gene-deleted vaccine strain. This method had the characteristic of high specificity to differentiate PRV form other virus. A comparison between FQ-PCR assay and conventional PCR assay were performed with 83 tissue samples, results showed that two methods match well. It indicates that TaqMan-MGB FQ-PCR assay provides a good method to detect PRV.

Key words: pseudorabies virus(PRV); fluorescence quantitative PCR(FQ-PCR); detect
