Effect of LcS on microbial diversity and composition in MACB of rWAS-exposed <i>Tcra</i>^-/- mice.

<p>(A) Shannon diversity index. Each point represents an individual animal; horizontal bar with errors represents mean ± SE, n = 7 ~ 8 per group. (B) Group distance. Data are presented as box plots, n = 7 ~ 8 per group. (C) Pcoa plot. Each point represents an individual animal, n = 7 ~ 8 per group. (D) Composition of MACB at the genus level. Data are presented as staked bar chart, n = 7 ~ 8 per group. control: <i>Tcra</i>^−/− mice not exposed to repeated water avoidance stress (rWAS), rWAS: <i>Tcra</i>^−/− mice exposed to rWAS. Mice are given placebo or LcS-fermented milk, which were denoted as the ‘placebo’ or ‘LcS’ group. * p < 0.05, *** p < 0.001 (control + placebo vs. rWAS + placebo), ^# p < 0.05, ^### p < 0.001 (rWAS + placebo vs. rWAS + LcS).
