Distribution of phylum-level bacterial taxa present in the fecal samples of mice from 12 different litters reared from parturition (Day 1) for 6 weeks on the antibiotic vancomycin (AB; left side of figure) or on tap water (dH2O; right side of figure). The figure is based on operational taxonomic unit abundances aggregated into phyla. Other in the figure legend represents unclassified phyla and Acidobacteria. Litters of mice from 6 different mothers reared on antibiotics (A1-6-x) and from 6 mothers reared on regular water (C1-6-x) until weaning. Mice were housed with their mothers until weaning at Day 22 and subsequently housed with their littermates while continuing to receive either vancomycin or regular water until Day 43. Analyzed samples were taken from cages containing a single mother and all of her pups on Days 21 (A/CX-6), 28 (A/CX-7), 35 (A/CX-8) and 42 (A/CX-9)
