Paneth (a) and goblet (b) cells in intestine of rats from different experimental groups. Rats were pretreated by oral gavage with Bacillus subtilis BSB3 (BSB3) or with PBS and were either exposed forced running or remained sedentary (n = 6 rats per condition). BEx, pretreated with BSB3, undergoing forced running; BCont, pretreated with BSB3 remaining sedentary; PEx, pretreated with PBS, undergoing forced running; PCont, pretreated with PBS remaining sedentary. Data with different superscript letters signify groups are significantly different (P < 0·05).
