Biogeographical analysis reveals strain-level metabolic adaptations of Bifidobacterium infantis across infant populations, suggesting a need for geographically matched precision probiotics.
as distinct species with divergent evolutionary histories but also uncovered profound biogeographic stratification and diet-driven metabolic adaptations at the strain level. These findings challenge the suitability of current probiotic strains and establish a robust scientific blueprint for developing next-generation, geographically matched therapeutics tailored to diverse infant populations.
