FIG 5.
AMR gene analysis of 416 clinical P. aeruginosa strains collected in 10 tertiary hospitals in Guangdong, China, from 2017 to 2020. Heatmaps were obtained by aligning the draft genome sequence of each strain to the AMR gene database. P. aeruginosa strains are clustered using a maximum-likelihood tree. Red and cyan blue depict the presence and absence, respectively, of AMR genes in the test strains. The right side denotes the category of AMR genes. Almost all strains contained intrinsic AMR genes, including fosA, armA, aph, blaOXA-50, and rsmA. Only 17.8% (74/416) of the strains had acquired exogenous AMR genes. Strain names are depicted at the bottom of the chart.
