A phylogenetic tree showing the relationship between all 45 carbapenemase-producing Enterobacteriaceae (CPE) genomes studied. The panel on the right shows the number of properties of the genomes—namely (from left to right), the presence (coloured symbol) and absence (no symbol) of the selected antimicrobial resistance genes (beta-lactamase genes: blaNDM-1, blaOXA-232; colistin-resistant mutations present in: mgrB, pmrB, YcaR), plasmid replicons (circles), bacterial species, sequence type based on MLST profiles, patient’s status at enrolment and patient number (Pstat&No). The phylogenetic tree was based on 123,598 core SNPs of 45 CPE isolates using a reference genome (K. pneumoniae QS17–0029; NCBI no.: GCA_003073235.1). Scale bar indicates the number of nucleotide substitutions per site
