摘要
本研究以纯化的原核表达的猪轮状病毒VP7抗原表位区域为抗原,建立了检测猪轮状病毒抗体的间接ELISA诊断方法。特异性试验表明,该抗原与其他7种常见猪病病毒(TGEV、PEDV、CSFV、PCV2、PRRSV、PPV、PrV)的阳性血清不发生交叉反应,批内和批间重复性试验的变异系数均小于10%;对来自不同猪场的血清的检测结果表明,该ELISA方法与中和试验检测结果符合率达94.8%。本试验建立的ELISA诊断方法具有良好的重复性、敏感性和特异性,为PRV的快速诊断、免疫猪群抗体监测和轮状病毒流行病学调查提供了一种快速、简便的血清学诊断方法。
An indirect ELISA was developed to detect antibody to PRV using the recombinant protein derived from the epitopes region of VP7 protein. The recombinant VP7 protein antigen showed no cross-reaction with the positive sera of other seven swine diseases (TGE, PED, CSF, PCV, PRRS, PPV, PR). The assay showed 94.8 % concordance with neutranization test. It was specific and sensitive, and could be used as a simple and rapid approach for monitoring of anti-PRV antibody and epidemiologic survey of PRV.
