Postinflammatory DSS mice exhibit elevated stool short-chain fatty acids. (A) Stool short-chain fatty acid content in postinflammatory DSS mice and controls. In antibiotic-treated animals (Abx), short-chain fatty acid concentration was below the limit of detection for butyrate and propionate. N = 6/group. (B) Stool short-chain fatty acid content after 2 weeks of antibiotic washout. CT and CT + Abx: n = 7, DSS and DSS + Abx: n = 6. One-way analysis of variance: ∗P < .05; ∗∗P < .01. Abx, antibiotics; CT, control; DSS, dextran sulfate sodium.
