ARS has led the PRRS Host Genetics Consortium (PHGC) project the goal of which is to identify genetic determinants of resistance/susceptibility of commercial swine to porcine respiratory and the reproductive syndrome virus (PRRSV) infection and associated growth effects. ARS will apply for NPB funds to perform the proposed research on PRRS viral persistence. The objectives for this work are 1) Determine levels of PRRS viral RNA in porcine tonsils of PHGC pigs to assess PRRS persistence; 2) Assess tonsil tissue RNA for immune correlates of PRRSV persistence; and 3) Expand the capacity of the PHGC database and improve public/private interface. ARS will provide funds to the ISU COOPERATOR for their efforts for objective 3) to update the PHGC database and website.
