Seroprevalence of bovine viral diarrhea/mucosal disease in southern Chile

The seroprevalence of bovine viral diarrhea/mucosal disease (BVD/MD) was estimated using the serum neutralization technique on 948 cow serum samples collected from 40 large herds of the IXth and Xth Regions in southern Chile. In addition, 116 bulls were tested. The seroprevalence was found to be hig...

Summary:The seroprevalence of bovine viral diarrhea/mucosal disease (BVD/MD) was estimated using the serum neutralization technique on 948 cow serum samples collected from 40 large herds of the IXth and Xth Regions in southern Chile. In addition, 116 bulls were tested. The seroprevalence was found to be high, with 700 of the 948 cows testing positive (73.8%) at a titer of ⩾1:5. The herd seroprevalence was 100%, with all the herds studied containing at least one positive animal. The seroprevalence in bulls was 81.0%. The survey indicated a high seroprevalence throughout the study area, with a maximum of 87.4% in the province of Cautin, IXth Region. Furthermore, the prevalence of reactors was high in animals managed in extensive production systems and there were no differences in prevalence observed between beef, dairy and mixed farming. The results indicate that BVD/MD is widely distributed in the adult bovine population of large herds in southern Chile.
