Toothbrush-associated microbiota are derived from a mix of prominent human and environmental taxa. a Distributions of putative origins of the toothbrush microbiota (genus-level) predicted by SourceTracker [23]. b PCoA displaying genus-level beta-diversity across toothbrush microbiota; color intensity indicates the cumulative fraction of taxa putatively derived from the human microbiome per sample. c Average relative abundances of highly abundant genera (i.e., > 2% average relative abundance) in all toothbrush metagenomes and those with putatively less than or greater than 50% microbiota derived from the human microbiome (i.e., primarily human-derived vs. non-niche-specific, respectively)
