Abstract: Border disease has always been considered as a sheep viral disease with relatively high prevalence all over the world, involving in abortion syndromes and creating of weak and abnormal lambs in countries where sheep husbandry industry is of high importance. Border Disease Virus (BDV) belongs to the genus Pestivirus within the family Flaviviridae and leads to abortion or birth of abnormal lambs in pregnant ewes. Such lambs often perish and constantly excrete virus, if continue their life time. Persistently infected ewes keep the virus for time and excrete it through saliva, faeces and urine. Considering that Sarab is regarded as an important bestial pole in northwest of Iran, it is necessary to study diseases damaging industry of animal husbandry in order to offer solutions required to control and prevent the diseases through identifying its causes. In present study, blood samples were collected from 100 ewes of different farms found in the region, sera were separated and stored at -30°C until conducting the experiments. Infection rate of the samples and antibody titer were distinicted through use of Serum Neutralization (SN) test on sera in laboratory. Finally it was found that 16% of the understudy samples were infected by the virus and had a distinictive antibodytiter.
