Summary:
- Researchers have discovered that the human gut microbiome can be transmitted between individuals through social interaction, challenging the long-held belief that our internal microbial communities are primarily shaped by genetics and early childhood development.
- The study utilized genomic analysis to track the movement of bacterial strains across social networks, suggesting that the "social microbiome" plays a significant role in human health, immune function, and the potential spread of both beneficial and pathogenic microbes.
