Fig. 2From: High-resolution genomic surveillance elucidates a multilayered hierarchical transfer of resistance between WWTP- and human/animal-associated bacteriaPhylogeny of a total of 388 Klebsiella pneumoniae (HKÂ WWTPs: 27; Public: 361) based on core genome SNPs. The inner colored ring indicates the isolation sources, and the outer colored ring indicates the geographical location of isolates. Our WWTP isolates are shown in red, with MLST information included. Green stars adjacent to the STs names indicate global isolates with the same STs as the WWTP isolates. The closely related isolates (defined as differing by < 30 core genome SNPs) between WWTPs and humans (red asterisks) are highlighted, with the adjacent number showing core genome SNPsBack to article page
