Background: Inflammatory bowel disease (IBD) is a chronic inflammatory disease associated with complicated interaction between immune, gut microbiota, and environmental factors in a genetically vulnerable host. Dysbiosis is often seen in patients with IBD. We aimed to investigate the fecal microbiota in patients with IBD and compared them with a control group in Taiwan. Methods: In this cross-sectional study, we investigated fecal microbiota in 20 patients with IBD and 48 healthy controls. Fecal samples from both IBD patients and controls were analyzed by the next-generation sequencing method and relevant software. Results: The IBD group showed lower bacterial richness and diversity compared with the control group. The principal coordinate analysis also revealed the significant structural differences between the IBD group and the control group. These findings were consistent whether the analysis was based on an operational taxonomic unit or amplicon sequence variant. However, no significant difference was found when comparing the composition of fecal microbiota between ulcerative colitis (UC) and Crohn's disease (CD). Further analysis showed that Lactobacillus, Enterococcus, and Bifidobacterium were dominant in the IBD group, whereas Faecalibacterium and Subdoligranulum were dominant in the control group at the genus level. When comparing UC, CD, and control group, Lactobacillus, Bifidobacterium, and Enterococcus were identified as dominant genera in the UC group. Fusobacterium and Escherichia_Shigella were dominant in the CD group. Conclusion: Compared with the healthy control, the IBD group showed dysbiosis with a significant decrease in both richness and diversity of gut microbiota.
