Metagenomic Analysis of Gut Microbiome in Korean Patients With Ulcerative Colitis

November 9, 2009 updated by: Seoul National University Hospital
The researchers will investigate gut microbiome in Korean patients with ulcerative colitis and normal control subjects using metagenomic analysis to elucidate the significant difference between two groups This study will help to understand the association between gut microbiome and inflammatory bowel disease.
