Study Finds Household Cohabitation Is Primary Driver of Microbiome Transmission, Including Diabetes-Linked Bacteria
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. Analyzing oral and gastrointestinal metagenomic data from 430 individuals across 207 households in Italy and Fiji, the study found that people living together share significantly more microbial strains than previously assumed under genetic inheritance models. Notably, cohabitation drives transmission of bacterial strains linked to Type 2 diabetes and cancer, suggesting household environments play a critical role in disease-associated microbiome transfer.
