Serology and viremia results in female pigs. Mean (± standard deviation) blocking percentage (bELISA; lines) and percentage of viremic animals (PCR; columns) to PPV1 in groups 1-NC and 4-NC (red) and groups 2-Vac and 5-Vac (green) in phase I (a) and phase II (b). Challenge was performed on SD 202 on phase I and on SD 385 in phase II. Discontinuous lines represent the seropositivity threshold. No data of PPV1 detection by PCR in vaccinated groups is shown, as no viremia was detected throughout the study. Nevertheless, statistical differences are represented. *Statistical differences (p < 0.05) in mean blocking percentages between groups. ☐Statistical differences (p < 0.05) in percentages of viremic gilts between groups
