Abstract: The purpose of this study was to investigate the prevalence of HoBi-like viruses in Japan and evaluate the immune response induced by bovine viral diarrhea virus (BVDV) vaccines available in Japan. No HoBi-like viruses were detected by RT-PCR and virus isolation in cattle sera collected in Japan between 2012 and 2017. Nevertheless, neutralizing antibody titers against HoBi-like viruses ranged from < 2 to 4,096, demonstrating cross-reactivity to HoBi-like viruses in cattle infected (naturally or vaccinated) with BVDV-1 and BVDV-2. These results suggest that continuous vaccination with both BVDV-1 and BVDV-2 contributes to the control of HoBi-like viruses in Japan.
