Relative mRNA expression of CLDN1, MUC2, OCDN, and ZO-1 in jejunal mucosa and relative mRNA expression of PTGS2, IL1B, IL6, and TNF in ileal mucosa of enterotoxigenic E. coli F18 challenged pigs fed diets supplemented with probiotics on d 21 post inoculation. ^a,bMeans without a common superscript are different (P < 0.05). Each least squares mean represents 8–10 observations. PRO1 = Bacillus subtilis DSM 32540; PRO2 = Bacillus pumilus DSM 32539
