Gut microbiota analyses of inflammatory bowel diseases from a representative Saudi population.

Background: Crohn's diseases and ulcerative colitis, both of which are chronic immune-mediated disorders of the gastrointestinal tract are major contributors to the overarching Inflammatory bowel diseases. It has become increasingly evident that the pathological processes of IBDs results from interactions between genetic and environmental factors, which can skew immune responses against normal intestinal flora.

Methods: The aim of this study is to assess and analyze the taxa diversity and relative abundances in CD and UC in the Saudi population.
