Figure 1

PCV2 viremia upon PCV2 natural infection. PCV2 genome copies (log10)/mL of serum in PCV2-vaccinated (PCV2-vac) and unvaccinated (C) pigs in the post-exposure (PE) period to PCV2 natural infection (15-26 weeks of age) quantified by qPCR. PCV2-vac pigs were vaccinated at 3 weeks of age using a PCV2a Cap protein-based subunit vaccine. (*): statistically significant difference between groups (p < 0.05). The cut-off value of 4 log10 (104) PCV2 genome copies/mL is assumed as the lowest limit for a productive infection.
