Figure 3. Peruvian peri-urban slum (PST) human fecal and sewage microbiota and resistomes.

Figure 3

a,c,e, Phylogenetic composition (n = 45/16/14/13 for human/street-access/influent/effluent). b,d,f, Resistome (n = 44/14/13/7 for human/street-access/influent/effluent). a, PCoA of weighted UniFrac distances between microbiota. Adonis R2=58.0%, p<0.001. b, PCoA of Bray-Curtis distances between resistomes with abundance-weighted coordinates of the top five most discriminative AR categories enriched in human or sewage habitats (squares, size proportional to overall abundance). Adonis R2=32.3%, p<0.001. c-d, *p<0.05, non-parametric Student’s t-tests, Bonferroni correction. c, Faith’s phylogenetic diversity. d, Observed AR proteins. e-f, Percentage of sewage e, microbiota and f, resistomes attributable to human feces at each sewage treatment stage, as determined by SourceTracker. *p<0.05, pairwise Wilcox tests, Bonferroni correction. Error bars = s.d., center bars = median.
