Gut Microbiome Signatures Tied to Dyslipidemia in 1,384-Person Study

Overview

• Shotgun metagenomic profiling showed distinct gut community structures separating people with abnormal lipid levels from those with healthy profiles.
• Bacteroides caccae was enriched in affected participants, whereas short-chain–fatty-acid producers such as Coprococcus eutactus and Coprococcus catus were more common in those without the condition, with Blautia obeum also higher in healthy individuals.
• Pathway analyses indicated enrichment of dTDP-beta-D-fucofuranose biosynthesis in cases and reductions in glycogen and peptidoglycan biosynthesis, with predicted lower pseudouridine.
• Resistome comparisons revealed no statistically significant group differences overall, including a marginal tetQ signal that lost significance after adjustment.
• The observational study from Seoul, published in Microbiology Spectrum, analyzed fecal and blood samples from 1,384 people—895 with the condition—adjusted for key host factors, and urges trials targeting ecosystem-level microbiome function.
