title: Diagnosis of natural exposure to bovine viral diarrhea in a vaccinated herd by measuring extended antibody titers against bovine viral diarrhea virus.
abstract: Two abortions occurred in a 150-head commercial cow-calf herd. Bovine viral diarrhea was suspected and confirmed by measuring extended titers against bovine viral diarrhea virus (BVDV) in a sample of 15 breeding females. Fifteen were sero-positive and 11 had significantly high titers (1:972-1:8748), likely due to natural exposure to cattle persistently infected with BVDV.
