Figure 2

Viral load in animals of the different treatment groups. Sera were analysed for PCV2 DNA by quantitative PCR specific for ORF1. Line charts represent levels of virus titres in serum samples of individual animals within the four study groups (CO = control, VA = vaccinated, IN = infected, VI = vaccinated & infected) at all investigated time points before and after PCV2 infection. The detection level of the qPCR was 25 virus copies/mL serum. Samples below this level were regarded as negative. The arrows indicate PCV2 vaccination on study day 0 (SD0) and experimental PCV2 infection on day 24 post vaccination, respectively.
