Changes in the Levels of Short-Chain Acids and Tryptophan Metabolites in Mouse Intestine during Experimental Colitis

The optimal balance of the intestinal microbiota is considered to be an essential part of the human body that affects many metabolic processes. However, the exact role of the gut microbiota in metabolism is still not fully understood. To investigate the metabolic role of gut microbiota, the content of short-chain fatty acids and tryptophan metabolites was studied in mice with sodium dextran sulfate-induced colitis. It was found that the production of short-chain fatty acids increased on experimental day 14, but by experimental day 60, they completely disappeared. At the same time, indoles of bacterial origin increased on experimental day 60.
