1. Microbial composition of mother and infant samples and shared bacteria within mother-infant pairs.
Microbial composition of mother and infant samples and shared bacteria within mother-infant pairs. (A) Quantitative microbial taxonomic composition of the metagenomic samples from milk and fecal samples of mothers and infants as estimated by MetaPhlAn2 analysis (77) (only the 20 most abundant species are indicated). Milk samples present low microbial richness compared to fecal samples. (B) Ordination plot of microbiome composition showing clustering of the three different sample types: mother feces, infant feces, and breast milk samples. The two infant samples close to the cluster of mother feces and in between the clusters of mothers and infants are from later time points, denoting the convergence of the infant microbiome toward an adult-like one. (C) The abundances of the 10 microbial species detected (>0.1% abundance) in at least one infant and the respective mother (shared species have been identified on the basis of samples from time point 1 [T1] only).
