Reduced Abundance of Butyrate-Producing Bacteria Species in the Fecal Microbial Community in Crohn's Disease

<b><i>Background:</i></b> The global alteration of the gut microbial community (dysbiosis) plays an important role in the pathogenesis of inflammatory bowel diseases (IBDs). However, bacterial species that characterize dysbiosis in IBD remain unclear. In this study, we assessed the alteration of the fecal microbiota profile in patients with Crohn's disease (CD) using 16S rRNA sequencing. <b><i>Summary:</i></b> Fecal samples from 10 inactive CD patients and 10 healthy individuals were subjected to 16S rRNA sequencing. The V3-V4 hypervariable regions of 16S rRNA were sequenced by the Illumina MiSeq™II system. The average of 62,201 reads per CD sample was…
