Fig. 4From: The structure and diversity of human, animal and environmental resistomesPrincipal component analysis of resistance genes and bacterial genera. The upper row shows the variation of a antibiotic resistance genes, b biocide/metal resistance genes and c bacterial taxa (genus level) among samples from all investigated environments, including human body sites and animals. The plots in the second row show the variation of d antibiotic resistance genes, e biocide/metal resistance genes and f bacterial genera among samples from the human microbiota onlyBack to article page
