摘　　要：牛病毒性腹泻病毒(Bovine viral diarrhea virus,BVDV)在全球流行率较高的基因亚型是BVDV-1b,其次是1a和2a;基因亚型1t和1n的全球流行率较低,1v亚型是近年新流行的基因亚型。BVDV新基因亚型的逐年出现说明其在不断地发生遗传变异,致其防控愈发困难。欧洲国家流行的BVDV基因亚型种类最多,说明BVDV在欧洲具有更高的遗传多样性。在亚洲发现的BVDV毒株数量则明显多于其他洲,1b是亚洲流行率最高的基因亚型。BVDV-3型在欧洲被报道次数最多,在亚洲也被报道过。本文对世界范围内BVDV的流行情况进行综述,可以丰富BVDV分子流行病学数据,也可为BVDV防控提供一定的理论基础。The most frequently-reported Bovine viral diarrhea virus(BVDV)subgenotype was 1b,followed by 1a and 2a.1t and 1n were the less reported subgenotypes,and 1v was a new popular subgenotype in recent years.Recently,the emergence of many new BVDV subgenotypes showed that continuous genetic variation made its prevention and control more and more difficult.The large number of various BVDV subgenotypes had been documented in European countries,indicating greater genetic diversity of BVDV in this continent.The number of BVDV strains found in Asia was significantly higher than those in other continents,and 1b was the most prevalent subgenotype in Asia.BVDV-3 had been reported most frequently in Europe and had also been reported in Asia.This study reviewed the worldwide prevalence of BVDV,enriched the molecular epidemiological data of BVDV,and provided a theoretical basis for the prevention and control of BVDV.
