Microbial composition of faecal samples from control mice. Faecal pellets were collected control mice from each of the vitamin D dietary groups (D++, D+ and D−). (A) Comparison of day 7 and day 35 species richness for samples from control mice (measured by chao1). (B) Day 7 Shannon’s diversity (H′). (C) Day 7, Relative abundance (%) of OTUs that correlated with serum vitamin D levels among controls using distance based linear modeling (DistLM) analysis. P-values calculated by PERMANOVA on Euclidean distance resemblance matrices generated from square root transformed relative abundance from each OTUs. n = 5/group for day 7 analyses, n = 4/group at day 35. *P < 0.05.
