摘要: 根据GenBank中登录的牛病毒性腹泻病毒(BVDV)基因序列,设计合成了1对特异性引物,建立了检测BVDV的RT-PCR方法。通过对该方法的特异性、敏感性和重复性进行试验,结果显示,该方法可从BVDV标准毒株Oregon C24V中扩增出471 bp的特异性片段,而对猪瘟病毒、牛传染性鼻气管炎病毒、牛呼吸道合胞体病毒、牛副流感病毒、MDBK正常细胞的扩增结果均为阴性。经对标准毒株的细胞毒进行检测,其敏感度达10-1 TCID50/mL。应用该方法对临床腹泻病牛各脏器样品进行检测,结果比病毒分离方法更为敏感,操作简便。表明建立的RT-PCR方法具有特异、灵敏、高效、快速的特点,可用于BVDV的临床检测及流行病学监测。

Abstract: A reverse transcription PCR (RT-PCR) assay for detection of bovine viral diarrhea virus (BVDV)was established using a pair of specific primers of BVDV. This method could specifically amplify a 471 bp fragment from BVDV Oregon C24V strain,but not from classical swine fever virus (CSFV),infectious bovine rhinotracheitis virus (IBRV),bovine respiratory syncytial virus (BRSV),parainfluenza virus-3 (PI3) and normal MDBK cells. The organs were detected by RT-PCR and virus isolated that collected from a sick calf with bovine viral diarrhea (BVD) like syndrome.These results indicated that the established RT-PCR assay was specific,sensitive,efficient and rapid for detection,monitoring and epidemiological investigation of BVDV infection.
