Macro genome and 16s ribosome Deoxyribo Nucleic Acid(rDNA) high-throughput sequencing were performed on the stool flora of the enrolled patients and controls,and the differences in the intestinal flora were analyzed using the LEfSe bioinformatics software.Results Compared with the control samples, all the tested patient samples showed statistically significantdifferences in the number of colonies of 5 bacterial phyla, 5 orders, 8 families, 11 genera, and 14 species(P < 0.05).Conclusion Compared with healthy people, patients with primary liver cancer have significant differencesin the intestinal flora composition. The alteration of the intestinal flora may be correlated with the occurrenceof primary liver cancer, and the intestinal flora may become a novel target for the prevention and treatmentof primary liver cancer.展开更多
