Persistant bovine viral diarrhoea virus (BVDV) is an important cultivate disease in cattle breeding. Persistent infected (PI) animals are the main virus carrier within and between flocks at virus transmission. Consequently the presence of persistent ınfected (PI) animals should be determined and removed from the herd. In this study, a total of 105 blood samples collected from the cattle were brought to the Bingol University Faculty of Veterinary Medicine around Bingol for different purposes. The presence of BVDV antigen and antibodies in these blood samples was investigated by enzyme immunoassay (ELISA) test. The presence of BVDV antigens in12/105 ( 11.42% ) and antibodies in 40/105 (38.09%) were detected of the samples. On the other hand In the tree cattle BVDV antibody was not detected but only the antigen was detected. This states that 3/105 (2.85%) animals had persistent BVDV infection. These animals are constantly sick and they spread out the virus. In this article, the presence and the incidence of persistent BVDV in the region was demonstrated 3/105 (2.85%) by this study. It has emphasized the need to control of the disease in the region for rational cattle breeding in the province. Eradication offers the supplementary advantage of developed herd health; however, it also composes a favorable cattle population that needs to be screened by strict biosecurity.
