Gut microbiota and inflammatory bowel disease

2015 
Inflammatory bowel disease is a chronic inflammation of the intestinal tract, which comprises two primary forms of Crohn's disease(CD) and ulcerative colitis(UC). Decades of studies have revealed that environmental factors, susceptibility genes, and gut microbiota are considered as the major determinants for the induction of IBD. The combination of factors has made IBD as an appropriate and a high-priority platform for studying host-microbiome interactions. More recently, profiling studies of the intestinal microbe have associated pathogenesis of IBD with characteristic alterations in the composition of the intestinal microbiota,reinforcing the viewpoint that IBD results from the altered interplays between the host and intestinal microbe. the studies of the gut flora in IBD were reviewed andthe multiple effects of intestinal microbiota-dysfunction on the IBD were described.The progress of intestinal microbiota alterations with different therapeutic methods in animal models and clinic trials were provided.
