In the case of PCV3, a higher number of PPV6 infections was observed in PCV3-positive gilts compared to PCV3-negative gilts (p < 0.01), but there was a higher number of PPV1 (p < 0.01) and PPV4 (p < 0.05) infections in PCV3-negative gilts compared to PCV3-positive gilts (Figure 4B). This evidence concerns the gene TIMM13 and infection.
