Figure 2From: Modification of PCV-2 virulence by substitution of the genogroup motif of the capsid proteinGenomic viral load of PCV-2 in sera of the four groups respectively inoculated with PCV-2a (2A), PCV-2b (2B), PCV-2a/motif2b (2C) and PCV-2b/motif 2a (2D). Results were expressed in log10 of viral genome copies per mL of serum, each point representing the genomic load in the serum of one piglet. The number indicated at each time represented the mean of genomic viral loads.Back to article page
