Crohn's Disease (CD)
Conditions
Brief summary
The characteristics of the intestinal microbiota in Crohn's disease and their relationship with disease pathogenesis have not yet been fully elucidated. Therefore, this study aims to analyze the microbial community characteristics in the intestinal mucosal tissue of Crohn's disease patients and fill this knowledge gap. Additionally, this research holds significant importance for understanding the etiology of Crohn's disease and predicting treatment outcomes.
