Abstract :
Bovine viral diarrhea disease is one of the viral diseases in cattle that were reported 10-90 percent in many countries. The causative RNA virus is a member of the family Flaviviridae and the genus pestivirus which is antigenically closely related with the virus of BD in sheep. Cattle are the most sensitive species to virus and are considered the principal reservoir of BVD viruses. A large proportion of BVD infections are subclinical and majority seropositive cattle. The purpose of this survey is to determine the prevalence of BVD disease in sanandaj city & to covprative with similar studies. In this study 410 serum samples were tested in serum neutralization test (SN) by using the NADL strain of BVD virus. The cows’ sera were collected from Sanandaj city of Iran. By SN test the rate of infection in all samples was 27.7%. This result done with similar study was approximately like that one carried out on 1357 serum samples from other provinces in Iran. Being on the border and consequently animals entering the country explains the high rate infection in Kurdistan province.
