Most cases suspected to be caused by within-ward transmissions. Mapping trees against reference genomes for A K. pneumoniae subsp. pneumoniae excluding STs represented with only a single isolate in the dataset, B K. quasipneumoniae and C K. variicola. D and E show ST-specific mapping of the relevant isolates against references for ST35 (D), ST39 (E), and ST14/ST15 (F). The coloured tips indicate isolates with < 5 SNPs distance to their nearest neighbour based on a root-to-tip approach to identify related clusters of isolates [40]. The colour ring in A shows the main STs, the columns in D–F show the year of isolate (left column) and major ward (right column)
