Core Tip
Core tip: Intestinal microbiota plays an important role in the pathogenesis of inflammatory bowel disease. However, there are few data on global alteration of microbiota in Chinese patients. In this study, fecal samples were subjected to 16S ribosomal DNA sequencing. Community richness and microbial structure in inflammatory bowel disease were significantly different from those in normal controls. The relative abundance of Bacteroidetes in the active Crohn’s disease group was significantly lower than that in the inactive Crohn’s disease group, and it showed a negative correlation with Crohn’s disease activity index, which indicates that Bacteroidetes may have a negative impact on inflammatory development.
