Panel a reports a circular cladogram generated through a hierarchical clustering (HCL) analysis based on selected publicly available shotgun metagenomes related to fecal samples of healthy infants aged from a few days to three years. The outer circle around the cladogram divides samples according to the identified sIGCSTs, while the inner circles provide a subdivision of fecal samples based on the defined sub-sIGCSTs. Panel b shows the three- and two-dimensional Principal Coordinate Analysis (PCoA) based on the same samples used for the HCL by coloring samples according to the ssIGCST they belong to. Color legend for panel a and b reports the cluster name and the number of infant fecal samples per each identified ssIGCST. Panel c displays the average abundance and prevalence of bacteria specifying each identified ssIGCSTs. Panel d depicts the distribution of samples for each ssIGCST divided by age groups.
