Open-access Investigation of bovine viral diarrhea virus in young bovines

AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    In this research we analyzed the presence of Bovine viral diarrhea virus in young bovines. We performed a serological study and viral isolament in 220 bovines from different counties. The serum-neutralization assay detected 123 (56%) positive bovines to BVDV and showed that 82% of the samples had SNT up to 512 and 18 %, more than 512. It was collected the buffy coats from these bovines to performed the viral isolament in culture cells and the presence of the virus was confirmed in four healthy bovines and one calves with respiratory symptoms. The five viral isolaments are non-citophatic strains.
