摘要 本试验的目的在于建立可同时检测猪伪狂犬病病毒(PRV)、猪轮状病毒(RV)、猪传染性胃肠炎病毒(TGEV)和猪流行性腹泻病毒(PEDV)的多重PCR检测方法。试验设计并合成了4对特异性引物,对样品中的PRV,RV,TGEV和PEDV进行了多重PCR扩增。结果显示,该方法可同时扩增出PRV(497 bp),RV(1356 bp),TGEV(238 bp)和PEDV(610 bp)的特异性目的片段,而对PPV,PCV,PRRSV和HCV的PCR扩增结果均为阴性。利用建立的多重PCR检测方法和单项PCR对60份临床病料进行检测。结果显示,两者的总符合率为95.0%。表明建立的多重PCR检测方法具有特异、快速、准确的特点,可用于上述4种病毒的早期鉴别诊断及大规模的流行病学调查。
