Fig. 7

Abundance of strains within each sample for breast milk (BM), cervix (CV), and blood spots (BS), and the maximum-likelihood phylogenetic tree for strain clusters (genotypes) of each family. Each color in the left panel is associated with the genotypes’ color on the right side. For all families, we use the same set of colors to represent different genotypes. However, for different families, the same colors are not directly related and do not represent the same genotype. The value shown in the tree represents the bootstrap value. The visualization of phylogenetic tree is generated with iTOL [56]
