Average and standard deviation of results for 10 mice per treatment are represented. ^∗Significantly different compared to the control; ^asignificantly different compared to L. rhamnosus DPC 6111 and L. gasseri ATCC 33323; non-parametric Mann–Whitney test was used to estimate the relationship between the groups; statistical significance was accepted at p < 0.05.
