Abstract
It was demonstrated that pre-existing BVDV-1 antibodies do not impact on the efficacy of live attenuated vaccines against CSF. Both C-strain “Riems” and marker vaccine “CP7_E2alf” were able to confer full protection against highly virulent challenge seven days after vaccination. However, slight interference was seen with serological DIVA diagnostics accompanying the vaccination with CP7_E2alf. Amended sample preparation and combination of test systems was able to resolve most cases of false positive reactions. However, in such a co-infection scenario, optimization and embedding in a well-defined surveillance strategy is clearly needed.
