Figure 8. Comparison of taxonomic and k-mer-based approaches on a small dataset of infant and maternal fecal metagenomes. (A) Average composition of the samples grouped by sample origin at the Family level, taxonomic families with a prevalence below 10% and a relative abundance below 5% were grouped as “Other”; (B) PcoA of the samples on the taxonomic profiles at the species level using a Bray-Curtis distance; (C) PcoA of the samples on the taxonomic profiles at the species level using a presence/absence Jaccard distance; (D) PcoA of the samples on the k-mer spectra using a Bray-Curtis distance (E) PcoA of the samples on k-mer spectra profiles using a presence/absence Jaccard distance. VD infants: Vaginally delivered infants.
