Summary

Story summary

A rat study shows gut microbiomes are influenced by the genes of close companions.
Researchers identified three genetic regions linked to gut bacteria, including St6galnac1, which affects mucus.
The study finds genetic influences can spread through social contact, impacting cage-mate microbiomes.
The findings suggest humans might have similar genetic effects on microbiome-related disease risks.
The study was published in Nature Communications.
