  1. Notes:
  2. “+” PCR-positive sample,
  3. “-“ PCR-negative sample.
  4. “n.a.” sample not-available.
  5. * serum titres at the beginning of the experimental study.
  6. ** Days post artificial insemination/s of sampling when viraemia was recorded.
  7. *** out of the 16 uterine tract samples, each corresponding to a foetus, 8 were PCV2 positive by PCR, but only in 7 cases there was concordance of the positive PCR result in both foetus and corresponding endometrium.
  8. § a foetus and its placenta were IHC positive, as well.
  9. §§ both of them are PCV2a, strain not-used for the infection.
