Correlation between in vitro and in vivo immunomodulatory properties of lactic acid bacteria

Figure 3 Protective effect of LAB strains against TNBS-induced colitis in BALB/c mice. Results are expressed as a % reduction of the mean macroscopic inflammation of mice treated with LAB as compared to the mean score of non-treated mice. Colitis index was assessed 48 h after TNBS administration. Each bar represents an independent experiment and corresponds to the ratio of control and LAB-treated mice groups (n = 10). ^aP < 0.05, ^bP < 0.01 vs TNBS-control group. The horizontal dashed lines indicate the 30% threshold of the uncertain statistical significance.
