Microbial profile along the maternal-infant axis: Early characterization and relationships in breastfeeding women and their newborns in a Colombian population

This study offers the first comprehensive characterization of the maternal-infant microbial axis in a specific Colombian population, highlighting distinct microbial profiles in healthy lactating mothers, human milk, and their infants, and indicating potential microbial interactions that could be important for early-life colonization.These findings should be considered in clinical and nutritional care strategies for lactating women, as they may provide an opportunity to promote health in the mother-infant dyad. Future studies will need to investigate factors, including nutritional factors, which may influence the microbiota along the maternal-infant axis.
