How such guild-level structure supports the gut microbiota to stably provide essential health-relevant functions to the host remains elusive. With high quality metagenome-assembled genomes as network nodes, here we identified a core microbiome signature made up of two robust competing guilds that together correlate with a wide range of host health conditions. Genomes in these two guilds kept their ecological relationship unchanged despite experiencing profound abundance changes during a 3-month high fiber intervention and 1-year follow-up in patients with type 2 diabetes. The genomes of one guild harbored more genes for plant polysaccharide degradation and butyrate production, while the other guild had more genes for virulence or antibiotic resistance. A Random Forest regression model showed that the abundance distributions of these genomes were associated with 41 out of 43 bio-clinical parameters in the study cohort. With these genomes as reference, Random Forest modeling successfully classified case and control of 8 chronic diseases in 12 independent metagenomic datasets from 1,816 participants across ethnicity and geography. This core microbiome signature may facilitate ecological management of chronic diseases.Competing Interest StatementLiping Zhao is a co-founder of Notitia Biotechnologies Company.
