Study Details

Brief summary:

The study involves characterizing the microbiota of patients with IBS, functional diarrhea, IBD, severe motility disorders and celiac disease.

This will be complemented by a translational phase of human-mouse hybrid experiments in which germ-free mice will be colonized with feces from these patients with different GI disease and non-disease controls and we will compare symptoms, microbiota composition and histological changes in the gut and in the brain of the mice.
