摘要: 根据GenBank发表的山羊痘病毒(goatpox virus,GPV)和羊口疮病毒(orf virus,ORFV)基因序列,分别合成针对GPV ITR和ORFV H2L基因片段的2对引物,以GPV和ORFV的核酸混合物作为模板,经优化反应条件,成功建立了快速鉴别检测GPV、ORFV的双重PCR方法。特异性试验结果显示,该方法对GPV与ORFV核酸的扩增能获得289和507 bp的特异性目的片段,而对FMDV、FPV、BTV、健康山羊皮肤的核酸扩增均为阴性;敏感性试验结果显示,该方法对GPV核酸的最小检出量为4 pg,对ORFV核酸为0.4 pg;对临床采集的12份病料进行双重PCR扩增,GPV检出率为25%(3/12),ORFV的检出率为75%(9/12)。结果表明,建立的双重PCR方法具有特异性强、敏感性高、快速简便等特点,可用于GPV或/和ORFV临床感染病例的联合检测与鉴别诊断。

Abstract: Two pairs of primers were designed according to the sequences of ITR gene of Goatpox virus (GPV) and H2L gene orf virus(ORFV) available in GenBank,respectively.Nucleic acids of GPV and ORFV were mixed as template, a duplex PCR assay was developed based on optimization of reaction conditions. Using the duplex PCR assay,the specific fragments 289 bp and 507 bp were amplified respectively from DNA samples of GPV and ORFV,but not amplified from foot-mouth disease virus,fowl pox virus,bluetongue virus and skin from normal healthy goat. The sensitivity of the duplex PCR reached 4 pg for GPV DNA and 0.4 pg for ORFV DNA,respectively. 12 clinical material were amplified by the duplex PCR assay,detection rate of GPV was 25%(3/12),detection rate of ORFV was 75%(9/12).The results showed that this duplex PCR assay was rapid,sensitive and specific for simultaneous diagnosis or differentiation of GPV and/or from ORFV infections.
