Fig. 6From: Fecal microbiota transfer between young and aged mice reverses hallmarks of the aging gut, eye, and brainDonor-derived species define the fecal microbiota composition of FMT recipients. A PCoA showing clustering of fecal microbiota samples from young and aged mice Pre–Abx (green) and post-FMT (orange), and overlaid with species driving the clustering. B Differential abundance analysis (results displayed as the mean difference in centered log ratio, CLR, and SE) of enriched species post-heterochronic transfer (Post-FMT) vs. pre-transfer (Pre–Abx) in young and aged mice. Family abundance, young mice receiving coeval transfer, and antibiotic-only groups shown in Fig. S3Back to article page
