Serum-virus titers after 08 V194 challenge for group CON2 (Mock-vaccinated control), 08 V194i (BEI-inactivated 08 V194), LVi2 (BEI-inactivated LV), 07 V063i2 (BEI-inactivated 07 V063) and PORatt2 (Porcilis® PRRS). Virus titers in serum (log10 TCID50/mL) were determined by virus titration on PAM, followed by immunoperoxidase staining for the PRRSV nucleocapsid protein. ↑ = challenge. Symbols represent individual animals and solid lines represent mean virus titers calculated on all animals present in each group. The dashed line indicates the mean titers for all animals in group CON2. The dotted line marks the detection limit for virus titration. Mentioned in the table: # = the number of viremic animals in the different groups at different time points. M = mean virus titer of all viremic animals in the group at different time points.
