OBJECTIVE
To estimate the prevalence and distribution of bluetongue virus antibody in sheep and goats in 25 townships of Khorasan Razavi. Bluetongue is an infectious, non-contagious, arthropod born viral disease of ruminants and has been reported from most of the tropical and subtropical regions of the world.
METHODS
A total number of 1 034 serum samples from sheep and goats were collected and transmitted to Serological Laboratory of Veterinary Council of Khorasan Razavi. Serums were screened for the presence of group-specific bluetongue virus antibody using competitive Enzyme Linked Immuno Sorbent Assay (c-ELISA).
RESULTS
The seropositivity of sheep and goats for bluetongue was found to be 89.2%. The highest prevalence rate was seen in Taybad, Khalil-abad and Torbat-jam (100%) and the least prevalence rate was seen in Jovein (55%).
CONCLUSIONS
The results showed that the majority of animals in the north-east of Iran are infected with bluetongue virus. High correlation between abortion history and seroposivity emphasize the economical importance of bluetongue virus in the sheep herds of the region.
目的
评估呼罗珊拉扎维省25个乡镇绵羊和山羊蓝舌病毒抗体的流行情况及分布。蓝舌病是一种由节肢动物传播的反刍动物传染性非接触性病毒病，已在世界上大多数热带和亚热带地区被报道。
方法
共采集1034份绵羊和山羊的血清样本，并将其送至呼罗珊拉扎维省兽医委员会血清学实验室。采用竞争酶联免疫吸附试验（c-ELISA）检测血清中蓝舌病毒群特异性抗体的存在情况。
结果
绵羊和山羊蓝舌病血清阳性率为89.2%。泰巴德、哈利勒阿巴德和托尔巴特贾姆的患病率最高（100%），乔温的患病率最低（55%）。
结论
结果表明，伊朗东北部的大多数动物感染了蓝舌病毒。流产史与血清阳性率之间的高度相关性强调了蓝舌病毒在该地区绵羊群中的经济重要性。
