Effects of LR1 on the expression of NODs and TLRs in the intestine of weaned pigs. (A) Relative mRNA expression levels of nucleotide binding oligomerization domain 1 (NOD1) and NOD2 in the mucosa of the jejunum and ileum. (B) Relative mRNA expression levels of toll-like receptor 2 (TLR2) and TLR4 in the mucosa of the jejunum and ileum. All data are expressed as the mean ± SEM (n = 8). Differences were determined by one-way ANOVA followed by Tukey’s test. *P < 0.05 compared with CON, ^#P < 0.05 LR1 compared with OA. CON, a basal diet; OA, a basal diet supplemented with 100 mg/kg olaquindox + 75 mg/kg aureomycin; LR1, a basal diet supplemented with 5 × 10¹⁰ cfu/kg L. reuteri LR1.
