(A) Relative abundance of B. infantis, (B) insulin sensitivity test, (C) area under curve of glucose post insulin injection, (D) serum alkaline phosphatase (ALP), and (E) serum alanine transferase (ALT) levels of WD-fed wild type (WT) mice as well as WD-fed FXR KO mice supplemented with and without B. infantis, MO, and B. infantis plus MO for 2 months. Data expressed as mean±SD. n ≥ 6 per group. *p<0.05, ***p<0.001, WT mice compared with FXR KO mice, and untreated FXR KO mice compared with treated FXR KO mice.
