With increasing demands for early diagnosis and treatment, gut microbiome research has become a forefront area. While numerous studies have shown that gut bacteria are closely related to the development of colorectal adenomas and cancer, research on viruses, archaea, and fungi is limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>From January 2019 to January 2024, this study collected 296 fecal samples from multiple centers and performed metagenomic analysis using shotgun sequencing. Principal coordinate analysis (PCoA) was conducted based on Bray-Curtis distance at the species level, \u03b1-diversity was calculated, and LEfSe analysis identified differential microorganisms. A random forest model was developed to distinguish adenoma patients from healthy individuals, with performance evaluated through internal validation using Bootstrap sampling and external validation with an independent cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>\n                      Significant differences in the relative abundance of certain bacteria (e.g.,\n                      <jats:italic>Phocaeicola_vulgatus<\/jats:italic>\n                      and\n                      <jats:italic>Prevotella_copri<\/jats:italic>\n                      ), fungi (\n                      <jats:italic>Candida_albicans<\/jats:italic>\n                      ), archaea (\n                      <jats:italic>Methanobrevibacter_oralis<\/jats:italic>\n                      ), and viruses (\n                      <jats:italic>Streptococcus satellite phage Javan301<\/jats:italic>\n                      ) were observed in adenoma patients.
