Due to antigenic differences between BVDV1 and BVDV2 strains, both pestivirus species are included in U.S. vaccines. The efficacy of these vaccines in preventing acute infections is evaluated based on reduction of clinical disease. While high virulence BVDV2 strains are used in U.S. vaccine efficacy studies, the BVDV1 strain used (NY-1) produces very little in the way of clinical disease. In order to identify a BVDV1 strain that generates a more pronounced clinical presentation, three field strains were compared to NY-1. Infection with two of the field strains resulted in significantly more pronounced clinical disease compared to NY-1. Decreasing the inoculation of a field strain by two logs did not significantly change clinical presentation.
