1Statistical comparisons were among CTRL (n = 6), INOC with mucohaemorrhagic diarrhea (n = 9) and INOC without mucohaemorrhagic diarrhea (n = 3) in trial 1. In trial 2, comparisons were among CTRL (n = 6), INOC with mucohaemorrhagic diarrhea (n = 8) and INOC without mucohaemorrhagic diarrhea (n = 4) in trial 2.† ‡ #*Within column, animals with similar superscripts are statistically different (P≤0.05).
