Infants share over a third of gut microbiome with mothers, University of Colorado study finds
A new study reveals that infants aged 2 to 4 months share on average just over a third of their gut microbiome with their mother's gut or vaginal microbiome, with notably higher microbial sharing occurring after vaginal births compared to C-section deliveries. The research provides new insights into how maternal microbiomes seed and shape infant gut ecosystems that influence future health.
