The developed countries have made a series of measures in preventing the disease and made a great purpose. This paper summarizes those methods in order to make a reference for the control of the disease in China.展开更多
【目的】了解新疆地区BVDV毒株的生物型和基因型。【方法】采集新疆石河子和伊犁地区疑似感染病毒性腹泻-黏膜病病毒牛的新鲜粪便174份,应用RT-PCR方法对其进行检测,将检测结果为阳性的样品接种于MDBK细胞上培养,电镜观察,测定毒价,使用...【目的】了解新疆地区BVDV毒株的生物型和基因型。【方法】采集新疆石河子和伊犁地区疑似感染病毒性腹泻-黏膜病病毒牛的新鲜粪便174份,应用RT-PCR方法对其进行检测,将检测结果为阳性的样品接种于MDBK细胞上培养,电镜观察,测定毒价,使用RT-PCR方法对细胞培养物进行鉴定,并提取质粒进行测序,对结果分析。【结果】该毒株可使MDBK细胞发生病变,扩增出一条286 bp目的片段,经同源性和遗传进化分析,确定为BVDV-1型毒株。【结论】分离到一株BVDV-1型新疆毒株,可使MDBK细胞发生病变,病毒粒子直径约为20~40 nm,毒株TCID5010-4.5/0.1 m L。展开更多
