Phylogenetic tree of NDM-1 and NDM-1/OXA-48-producing Klebsiella pneumoniae isolates, Germany, January–September 2022 (n = 200)

We determined pairwise allelic differences between isolates and calculated a neighbour-joining tree using SeqSphere+. Metadata were annotated using Interactive Tree OF Life [20]. Sequence types (ST) are colour-coded. Coloured circles: detected carbapenemases; reddish band: Kleborate-derived virulence score [8]; 3-letter country code: presence abroad before diagnosis, as documented for isolates at the NRC (black) or matched notifications (blue).
