摘要:
为开发一种快速、准确检测猪流行性腹泻病毒(Porcine epidemic diarrhea virus, PEDV)的实时荧光定量PCR方法,根据引物设计原则在病毒基因组序列保守区设计了一对PEDV特异性引物,通过系统优化建立了EvaGreen实时荧光定量PCR方法,对其特异性、灵敏度和重复性进行了分析,并将该方法应用于90份临床样品检测。结果表明:该实时荧光定量PCR可以特异性地检测PEDV,对其他非靶标病毒无交叉反应,最低检测限为5 copies/μL;使用3个不同浓度的标准品进行批内和批间重复,Ct值的变异系数在2-8%以下,表明该方法重复性好;临床样品中PEDV的阳性率为48-9%。建立的实时荧光定量PCR是一种快速、准确、高度灵敏且特异的检测方法,可用于PEDV流行病学调查和临床诊断。
