Objective:To estimate the prevalence and distribution of bluetongue vims 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 1034 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).Kesults:The seropositivitv 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 vims.High correlation between abortion history and seroposivity emphasize the economical importance of bluetongue virus in the sheep herds of the region.
