Bovine viral diarrhea virus (BVDV) has major impacts on beef cattle production worldwide, but the understanding of host animal genetic influence on illness is limited. This study evaluated rectal temperature, weight change and feed intake in Bos indicus crossbred steers (n = 366) that were challenged with BVDV Type 1b, and where family lines were stratified across three vaccine treatments of mo...

The onset of protection after the administration of a modified-live bovine viral diarrhea virus (BVDV) vaccine was determined. Protection was determined following experimental infection with a virulent type-2 BVDV (strain 1373) in cattle vaccinated 3, 5, or 7 days before BVDV infection. Protection, as measured by reduced virus shedding, lack of leukopenia, reduction in viremia, and reduced mort...

To gain further insight into the genomic features of bovine viral diarrhea virus 1 (BVDV-1) subgenotypes, we sequenced the complete genome of BVDV-1n Shitara/02/06 and BVDV-1o IS26NCP/01. The complete genome of Shitara/02/06 and IS26NCP/01 shared 77.7 to 79.3% and 78.0 to 85.7% sequence identities with other BVDV-1 subgenotype strains, respectively.

Bovine viral diarrhea virus (BVDV) is a globally-distributed agent responsible for numerous clinical syndromes that lead to major economic losses. Two species, BVDV-1 and BVDV-2, discriminated on the basis of genetic and antigenic differences, are classified in the genus Pestivirus within the Flaviviridae family and distributed on all of the continents. BVDV-1 can be segregated into at least tw...
