TOPLINEPeople with close family ties who lived together shared more oral and gut microbes with each other than with other people in their communities.METHODOLOGYResearchers analyzed 1644 paired oral and fecal metagenomes from 808 individuals in 207 households in Italy and Fiji to map microbiome strain transmission patterns across household and body sites.They used strain-level phylogenetic analysis to identify shared microbial strains between individuals with close family ties who were living together and compared strain-sharing rates across different household relationship types (eg, siblings or partners).Additional analyses examined the transmissibility of individual microbial species and their associations with cardiometabolic and cancer biomarkers.TAKEAWAYCohabitants shared…
