Abstract;Bovine viral diarrhea virus (BVDV) has been segregated into two genotypes, typs 1 and type 2. To determine the efficacy of the commercially available bovine viral diarrhea type 1 vaccine used in Japan against BVDV type 2, cavles were infected with BVDV type 2 strain 890 4 weeks after asministration of the vaccine. The vaccinated calves did not develop any clinical sings and hematological changes such as observed in unvaccinated calves after the challenge. Furthermore, the challenge virus was not recovered from the vaccinated calves throughout the duration of the experiment, whereas it was recovered from all unvaccinated calves. The bovine viral diarrhea vaccine used in Japan is efficacious against infection with BVDV type 2 strain 890. (author abst.)
