Effects of bacterial colonization on colonic mucin glycosylation. (A) Proportion of neutral and acidic oligosaccharides (carrying sulfate, N-acetyl neuraminic acid or N-glycolyl acid residues) in germfree (GF) rats (n = 3), Bt-2d (n = 2), Bt-30d (n = 3) and Bt + Fp 30d (n = 3) rats. (B) Ratio of sialylated to sulfated O-glycan chain in each group of rats.
