Core Tip
Core Tip: Further study is required on gut microbiota alterations in patients with ulcerative colitis (UC). This study aimed to analyze the relationship between clinical features and the intestinal microbiota, including bacteria and fungi, in Chinese patients with UC. Gene amplicon sequencing of 16S rRNA gene and fungal internal transcribed spacer gene was applied. A total of 89 UC patients and 33 controls were enrolled. Results showed that the intestinal bacteria flora of patients with UC differed significantly in terms of various sample types and disease activities. The intermicrobial correlations changed in patients with UC compared with controls.
