Genome-based phylogenetic analysis of the 22 3rd generation cephalosporin-resistant K. pneumoniae isolates. A Maximum Likelihood Tree based on the concatenated MLST gene sequences (gapA, infB, mdh, pgi, phoE, rpoB, and tonB); B UPGMA dendrogram based on ANIb pairwise values comparisons among the genomes, and C UPGMA dendrogram representing the degree of similarity of the genomes based on the amino acid sequences presence or absence. Red, green and blue symbols in the dendrogram refer to isolates obtained from patients, wastewater and clinical environment, respectively
