a Stacked bar plots showing the most abundant genera (top 5 from each dataset) among human stool samples from the Human Microbiome Project, wastewater from Milwaukee residential sewers, influent from a 5-year time series of two Milwaukee WWTPs, and WWTPs from across the US. Bar height indicates the proportion of that genus among the abundant genera visualized. Bar colors denotes the genus. b Proportion of abundant genera from Fig. 2a in all WWTP influent samples. c Proportion of all human-associated ASVs in the three wastewater datasets. d Proportion of ASVs from human microbiome body site sources among all wastewater samples. For bd, circles indicate sample value and lines indicate dataset mean
