  1. *The mean IgM, IgG and IgA mucosal antibody titers ± SD in the control group and the mean IgA mucosal titers ± SD in the infection group were 0 ± 0.00 for all time points. Antibody titers were defined as the reciprocal of the highest dilution that gave an absorbance reading at 405 nm above the cut-off value (mean absorbance of seronegative pig serum + twice the standard deviation).
  2. aP < 0.05 for a comparison of the control group and the infection group.
  3. bP < 0.05 for a comparison of the control group and the re-infection group.
  4. cP < 0.05 for a comparison of the infection group and the re-infection group.
