Serological profile of some viral infections in unvaccinated cattle in Turkey

Abstract

In this study, 936 unvaccinated cattle sera were analyzed against five viruses: bovine viral diarrhea virus (BVDV), parainfluenzavirus type 3 (PIV-3), bovine adenovirus type 1 (BAdV-1), bovine adenovirus type 2 (BAdV-2) and bovine adenovirus type 3 (BAdV-3), which were caused by respiratory system diseases in cattle. The study used the serum neutralization (SN) test - a conventional method. The seropositive rates for each virus were found to be 20.19%, 41.02%, 23.82%, 21.90% and 8.1%, respectively. Evaluation of the data revealed that 25.64% of the sampled population was seronegative against the investigated viruses, 74.36% were seropositive for one or more of them and 42% of animals were found to be seropositive against any of the investigated viruses. 25.42% of the animals were seropositive against two viral infections whereas 5.23% of the animals were found to be seropositive against three viral infections and 0.1% of the animals were detected to be seropositive for four viruses.
