Numbers of Wa HRV-specific ASC per 5×105 MNC obtained from systemic lymphoid tissues (blood and spleen) and MLN draining the small and large intestine at 21 PID.

When comparing ASC numbers of the same isotype among treatment groups, different letters indicate a significant difference (Kruskal-Wallis rank sum test, p<0.05). n = number of piglets in each group. The IgM ASC response was not included as no IgM ASC were detected in most of the groups of pigs.
