Estimated Maximum Likelihood phylogenetic analysis of KPC-Kp (N=87) isolated from three hospitals in Northern Italy and reference genomes (N=16). The Maximum Likelihood tree was inferred from a core-SNP alignment of 25,322 bp. The phylogeny was estimated with IqTree using the best-fit model of nucleotide substitution GTR+F+G4 with 1,000 replicates and fast bootstrapping. The numbers on the leaves represent the sample IDs. Reference genomes are displayed in grey. Bootstrap values higher than 90 are displayed on branches. Information regarding samples is annotated: hospital of origin, isolation date, isolation site, sequence type (ST), capsular locus (K locus), lipooligosaccharide locus (O locus), and the presence (solid figures) or absence of antimicrobial resistance genes, virulence factors and transposons, number of plasmids and bacteriophages, colonization, or infection status
