Schmallenberg virus (SBV) is an emerging single-stranded RNA virus being classified under Simbu serogroup of Bunyaviridae family. This study aimed to detect antibodies against SBV in cattle for the first time in three eastern provinces of Iran. Blood samples were randomly collected from jugular veins of ۲۷۰ cattle, from ۱۹ farms in Razavi Khorasan, South Khorasan and Sistan and Baluchistan provinces. Separated sera were analyzed to find SBV antibody using ID vet® SBV indirect multi-species enzyme-linked immunosorbent assay test kit. From a total of ۲۷۳ serum samples analyzed for SBV presence, ۱۲.۴۵% (n = ۳۴) were positive for SBV antibody. Risk factors including breed, age and geographic area showed a statistically significant relationship with the virus prevalence. In conclusion, the seroprevalence of SBV is not high; but it is considerable in the studied parts of Iran. This is the first study regarding SBV seroprevalence in cattle population of eastern Iran and further studies about the virus epidemiology are recommended.
