Fecal microbial dysbiosis in Chinese patients with inflammatory bowel disease

AIM: To analyze the alterations of fecal microbiota in Chinese patients with inflammatory bowel disease (IBD). METHODS: Fecal samples from 15 patients with Crohn's disease (CD) (11 active CD, 4 inactive CD), 14 patients with active ulcerative colitis (UC) and 13 healthy individuals were collected and subjected to 16S ribosomal DNA (rDNA) gene sequencing. The V4 hypervariable regions of 16S rDNA gene were amplified from all samples and sequenced by the Illumina MiSeq platform. Quality control and operational taxonomic units classification of reads were calculated with QIIME software. Alpha diversity and beta diversity were displayed with R software. RESULTS: showed a negative correlation with the CD activity index scores. CONCLUSION: may have a negative impact on inflammatory development.
