SCREENING FOR PERSISTENTLY INFECTED CATTLE WITH BOVINE VIRAL DIARRHEA VIRUS IN SMALL-HOLDER CATTLE FARMS LOCATED IN SAMSUN PROVINCE, NORTHERN TURKEY - H. Tutuncu; Z. Yazici (Journal of Animal and Plant Sciences, 2016)
Blood samples were collected from 651 cattle of 119 small scale family farms from four different regions in Samsun Province, Northern Turkey. Bovine Viral Diarrhea Virus (BVDV) antigens and antibodies in samples were investigated with Antigen Capture ELISA (ACE) and Serum Neutralization Test (SNT), respectively. Two out of 651 (0.03%) animals were found positive for BVDV antigens by ACE and antibody negative by SNT in the fırst sampling. The blood samples from antigen positive animals were re-taken after 28 days from the first sampling. These two positive animals were found antigen negative and antibody positive. 211 of the 651 (32.41%) animals were found seropositive by SNT. Antibody titers were calculated between 1:8 and 1:512.
