Partial nucleotide sequence of the capsid polypeptide coding gene 1D (VP1) was determined for 68 serotype O foot-and-mouth disease viruses isolated between 1983 and 1995 from outbreaks occurring in Saudi Arabia. The sequences were compared with previously published sequences: 14 viruses of Middle Eastern origin (isolated between 1987 and 1991); and with four vaccine virus strain sequences, three originating from the Middle East (O1/Turkey/Manisa/69, O1/Sharquia/Egypt/72 and O1/Israel/2/85) and one from Europe (O1/BFS 1860/UK/67). The virus isolates from Saudi Arabia and the Middle East vaccine virus strains formed a related genetic group distinct from the European O1 virus. Within this large group 12 distinct genetic sublineages were observed.
测定了1983年至1995年间从沙特阿拉伯疫情中分离出的68株O型口蹄疫病毒衣壳多肽编码基因1D(VP1)的部分核苷酸序列。将这些序列与先前发表的序列进行了比较:14株中东起源的病毒(1987年至1991年间分离);以及4株疫苗病毒株序列,其中3株起源于中东(O1/土耳其/马尼萨/69、O1/沙基亚/埃及/72和O1/以色列/2/85),1株来自欧洲(O1/BFS 1860/英国/67)。来自沙特阿拉伯的病毒分离株和中东疫苗病毒株形成了一个与欧洲O1病毒不同的相关遗传群体。在这个大群体中观察到12个不同的遗传亚系。
