Across 1,027 fecal metagenomes from seven cohorts, 8,278 coverage-defined structural variations across 51 gut bacterial species distinguish colorectal cancer from healthy individuals via strain-level SV heterogeneity.
- Why it matters: Most colorectal cancer microbiome work emphasizes species abundance, missing genetic structural variation within strains that may better reflect disease-linked biology.
- What they did: The study profiled microbial genome structural variations in metagenomes, clustered individuals by SV patterns, and combined taxonomic-SV markers for early CRC detection using MicroSVsProfiler.
- The result: SV-based clusters differed significantly between healthy and CRC, SVs showed regional heterogeneity, and SV regions linked to glycoside hydrolases associated with disordered carbohydrate metabolism in CRC.
