An Investigation of Bovine Viral Diarrhoea Virus (BVDV) and Bovine Parainfluenza Type 3 Virus (BPI3V) Infections in Small-Scale Cattle Herds in Afyonkarahisar Province

Özet

Respiratory and reproductive system disorders are the most important problems of ruminant breeding and cause great economic loss. Bovine viral diarrhea and bovine parainfluenza 3 infections are among the leading respiratory pathogens and are very common in our country. The aim of this study is to serologically investigate the status in family-type small-scale enterprises of these two virus infections throughout Afyonkarahisar province. For this purpose, 1.279 adult cattle blood samples were collected from all the districts, which were not vaccinated recently for these infections. Sera samples were controlled using standard virus neutralization test and seropositive samples were re-tested to determine antibody titers. Pestivirus-specific antibody presence was detected in 978 (74.9%) cattle, and the rates varied between 50.7% (İhsaniye) and 92.8% (Çay) according to the districts. For BPI3V, the least positivity was found in Sinanşa (58.8%) while the highest rate was detected in Emirdag with 97.5%. In total, 82.7% (1.058 / 1.279) seropositivity was determined.
