Evolutionary history and microbial cross-feeding shape lifestyle-stratified dominance of Bifidobacterium longum subspecies in infants
A global genomic atlas of >7,000 MAGs/genomes from infants, domesticated animals, non-human primates, and ancient humans helps explain subspecies differentiation in the gut microbiota of Western and non-Western infants and provides a framework for community-mediated interventions in early life.
