Maturation of the infant microbiome community structure and function across multiple body sites and in relation to mode of delivery

Chu et al, Nature Medicine

Abstract

Human microbial communities are characterized by their taxonomic, metagenomic and metabolic diversity, which varies by distinct body sites and influences human physiology.

However, when and how microbial communities within each body niche acquire unique taxonomical and functional signatures in early life remains underexplored.

We conclude that within the first 6 weeks of life, the infant microbiota undergoes substantial reorganization, which is primarily driven by body site and not by mode of delivery.
