Pouch Inflammation Is Associated With a Decrease in Specific Bacterial Taxa

Reductions in protective bacteria and increases in inflammatory bacteria are associated with pouch inflammation in patients with UC who underwent pouch surgery. The finding that antibiotics exacerbate dysbiosis indicates that these drugs might not provide long-term benefit for patients with pouchitis. Additional studies of this form of dysbiosis could provide information about the pathogenesis of Crohn's disease.
