Technical Abstract: Severe acute BVD caused major losses to the cattle industry in Ontario during 1993 to 1995, with death of animals of all ages with pneumonia, diarrhea, or abortions. The outbreak was attributed to Type 2 BVDV using cross-neutralization assays and PCR typing technology. Disease due to Type 2 BVDV was readily diagnosed using standard reagents for BVDV Type 1. It is apparent that both Type 1 and Type 2 BVDV have been present in Ontario since at least 1991, yet severe disease has only been recognized in Ontario since 1993. This indicates that BVDV Type 2 designation does not, in itself, imply enhanced viral virulence. As yet, there are no laboratory markers for BVDV virulence.
