Fig. 3. Postnatal assembly of the humanized gut microbiota.
(A) Rarefaction curves measuring bacterial diversity in the fecal communities (species-level phylotypes defined by ≥97% identity). The curves are based on V2 16S rRNA gene sequences obtained from mice prior to weaning (P14) and after weaning (P28). Values are mean±95% CI. (B) Taxonomic distribution [RDP level 3 (27)] of the gut microbiota sampled from mice from postnatal days P14 to P85. Values represent the average relative abundance across all samples within a given group.
