Study Finds Household Cohabitation, Not Genetics, Drives Transmission of Diabetes- and Cancer-Linked Microbes
By
Neuroscience News
Summary
Researchers mapped the environmental and physical dynamics of human microbiome transmission, proving that household cohabitation is the primary vector for strain-level bacterial colonization. The study analyzed oral and gastrointestinal metagenomic data from 430 individuals across 207 households in Italy and Fiji, finding that cohabiting individuals share significantly more microbial strains than previously assumed under genetic inheritance models. The research identified highly transmissible bacterial strains linked to Type 2 diabetes and cancer, challenging traditional assumptions about disease transmission and genetic predisposition.
