Bluetongue is a viral disease of ruminants transmitted by Culicoides biting midges spreading rapidly over large distances. The virus occurs worldwide between latitudes ~35◦S and 50◦N. We describe demographics, distribution and seroprevalence of Bluetongue virus (BTV) infection In Iran from sera of 262 sheep by c-ELISA during the 4 seasons. Two hundred three (77.48%) were positive to viral antibodies. We found much higher incidence (P < 0.001) in females (79.39%) and older > 3 year sheep (64.5%) but found no significant differences between seasons or abortions. We report high prevalence of bluetongue in sheep in Kohgiluyeh and Boyer-Ahmad provinces, Iran.
Key word: Bluetongue, sheep, c-ELISA, Iran.
