Effect of M_PI transfaunation on intestine length, villus height, and crypt depth in ileum. A: total small intestine length was measured in GF, M_PI-L, M_PI-H, and SPF groups (n = 3–6 mice). B: mean ileal villus height was measured in GF, M_PI-L, M_PI-H, and SPF mice (n = 3–6 mice). C: mean crypt depth was measured in GF, M_PI-L, M_PI-H, and SPF mice (n = 3–6 mice). Results are presented as means ± SD. One-way ANOVA with post hoc Tukey's HSD test was used to compare the groups. *P < 0.05, **P < 0.01.
