FIG 3.

Strain prevalences worldwide based on the HumGut database. Global prevalences of four Bacteroidaceae strains based on data from the creation of the HumGut database (13). The heat maps depict the relative abundances and prevalences of these strains in both the adult population (A) and the infant population (B). The data set used to generate these results includes 2,933 fecal samples from healthy adults and 598 fecal samples from healthy infants. “Infant population” refers to children at and below 1 year, while “adult population” refers to those above 1 year of age.
