摘要 为建立一种快速诊断牛病毒性腹泻疾病的方法,利用本研究室分离鉴定的牛冠状病毒(BCV)和牛轮状病毒(BRV)毒株,根据GenBank中登录的BCV、BRV核苷酸序列分别设计并合成了两对能特异性扩增BCV、BRV的引物,经过条件优化,建立了检测BCV、BRV的双重PCR方法,扩增两种病毒的片段分别为244bp和382bp。该方法检测BCV和BRV的敏感度分别为1个和100个TCID50/100μL。应用这一方法能从病料中检测出这2种病毒。结果表明该双重RT-PCR方法具有很好的特异性和敏感性,可用于这2种病毒性疾病的快速诊断。 A double PCR was developed based on two pairs of primers designed according to the published sequences of bovine coronavirus (BCV) and bovine rotavirus (BRV). The assay was shown to amplify a 244 bp specific segment from BCV virus and a 382 bp segment fxom the BRV virus, with a sensitivity of TCID50/100 μL for BCV 1 and 100 TCID50/100 μL for BRV. This assay could also be successfully applied to detect BCV and BRV in the feces. These results indicated that the double PCR is a sensitive and specific assay for the clinical diagnosis.
