Contaminant-aware blood bacterial signatures at a decontam score of 0.175. A Top 25 genera and their respective taxonomic classification. The bandwidth is proportional to the amount of ASVs within each phylum, genera are ordered from bottom to top within each family according to alphabetical order, and taxonomy was generated with all available baseline samples (n = 64) and follow-up samples at 3 months (n = 48) and 1 year (n = 48). B Relative abundance of phyla within samples with follow-up sequencing at all timepoints: baseline (n = 48), 3 months (n = 48), and 1 year (n = 48) after bariatric surgery. Phyla with an abundance within the whole dataset of less than 10% are flagged under the category “< 10% Abundance.” Taxonomy is shown for matched subjects with and without T2D (n for each group = 24) at each timepoint separately. C Relative abundance of core genera belonging to the phyla with an abundance of > 10% within samples with follow-up sequencing at all timepoints: baseline (n = 48), 3 months (n = 48), and 1 year (n = 48) after bariatric surgery. Taxonomy is shown for matched subjects with and without T2D (n for each group = 24) at each timepoint separately
