We determined the in vitro and in vivo translational efficiency mediated by the internal ribosomal entry site (IRES) from eight BVDV2 field isolates varying in virulence using a bicistronic reporter vector in rabbit reticulocyte lysates (RRL), and in primate and bovine cell lines. Using a T7-promoter system, the high virulence isolates had greater translational efficiencies in bovine lymphocytes (BL-3 cells), than did the low virulence isolates. The low virulence isolates translated with greater efficiencies than the high virulence isolates in RRL, African green monkey kidney (CV-1) and bovine turbinate (BT) cells. Our results demonstrate that despite a high degree of …
