Intestinal microbiota, fecal microbiota transplantation, and inflammatory bowel disease

Abstract

Inflammatory bowel disease (IBD) is a complex set of diseases that lead to chronic inflammation in the gastrointestinal tract. Although the etiology of IBD is not fully understood, it is well-known that the intestinal microbiota is associated with the development and maintenance of IBD. Manipulation of the gut microbiota, therefore, may represent a target for IBD therapy. Fecal microbiota transplantation (FMT), where fecal microbiota from a healthy donor is transplanted into a patient's GI tract, is already a successful therapy for Clostridium difficile infection. FMT is currently being explored as a potential therapy for IBD as well. In this review, the associations between the gut microbiota and IBD and the emerging data on FMT for IBD will be discussed.
