The risk of transmission from sheep experimentally infected with BVDV-1c during the acute phase to BVDV naïve sheep

Five wethers, experimentally infected with BVDV-1c, were co-mingled with five pestivirus naïve wethers for a period of seven weeks. Weekly blood samples were collected and tested for the presence of BVDV-specific antibodies and BVDV antigen. Acute infection was successful in the experimentally inoculated animals, with antibodies detected in all five wethers by Day 35 post inoculation. Transmission of BVDV-1c was not shown to occur between these acutely BVDV-1c infected wethers and the naïve wethers co-mingled with them.
