Figure 3. — Genomic characterization of 140 carbapenem-resistant Klebsiella pneumoniae isolates. Upper panel: Maximum-likelihood recombination-free phylogenomic tree rooted to the midpoint of the genomic distances. The inner colored ring shows the ST; the external colored ring represents the year of isolation. The external red circles indicate the presence of the carbapenemase-encoding genes bla_KPC, and bla_NDM. Lower panel. Frequency ST by year of isolation. Abbreviations: bla_KPC, Klebsiella pneumoniae carbapenemase; bla_NDM, New Delhi metallo-β-lactamase; ST, sequence type.
