Serological research of Bovine Viral Diarrhea Virus (BVDV) infection in cattle farms in Antalya province

The aim of the study was to research seroprevalence of Bovine Viral Diarrhea Virus (BVDV) infection in cattle farms in Antalya province. In the study, blood samples taken among 470 cattle aged between 6 months and 15 years from 94 farms were used. Blood samples of the animals were collected from V. Jugularis in 10 ml sterile vacuum tubes. Tubes were centrifuged 10 min. at 2000 rpm. The serums were stored in a deep freezer at -25 °C until testing. BVDV (Ab)-ELISA and BVDV (Ag)- ELISA test kits were used to determine the presence of antibody (Ab) and antigen (Ag) respectively in the serums. Of these samples, 322 (68.51%) were seropositive, 148 (31.48%) were seronegative and 13 (2.76%) were persistent infected. Seropositivity rate was found to be statistically significant among age groups (p <0.05). Also it is found that seronegatifity decreased as age increased. The study has the feature of being the first study to determine the seroprevalence of BVDV infection in Antalya province. As a result; When seropositivity and PI ratio of BVDV infection are considered, it is seen that the infection is widespread in Antalya province. For this reason, taking necessary control and protection measures against disease is important for the economy of the region and the country.
