Fig. 3

Piglets immunized with IgM-adjuvanted inactivated PRRSV vaccine demonstrated improved viral shedding after heterologous HP-PRRSV challenge. A. Nasal swab samples were collected at the indicated time points and harvested using TRIzol reagent for PRRSV RNA detection using IDEXX RealPCR PRRSV-2 RNA Mix. The Ct value of each sample is presented for comparison and was based on the manufacturer cut-off Ct value of 38. B. Serum samples were collected from each piglet at the indicated time points and processed using TRIzol reagent for PRRSV RNA detection.
