Abstract
AIM
To detect the distribution of intestinal flora between ulcerative colitis (UC) patients and normal controls by high-throughput sequencing to discover the genus structures related to the formation and development of UC.
METHODS
Chromosomal DNA was extracted from each sample, and the length of DNA fragment was detected and quantified. Gene amplification and sequencing of the V3 region of 16S rRNA were then performed.
RESULTS
The structure of intestinal flora in UC patients exhibited a significant decrease in the numbers of Bacteroidetes, Proteobacteria, and Firmicute, compared with that of healthy controls. There were significant differences (P < 0.05) in the mean abundance of 11 metabolic pathways between the two groups.
CONCLUSION
There is a strong correlation between the abnormal changes of the intestinal flora structure and the occurrence and development of UC. Multiple metabolic pathways are involved in the formation and development of UC. It is helpful to understand the molecular pathological basis of UC by analyzing the key structures of bacterial flora, which will provide a theoretical basis for the reasonable design of new drugs.
