Aerobactin and salmochelin locus variants found in Klebsiella pnuemoniae. a A single aerobactin (iuc) locus structure was found in K. pneumoniae. b Four different structures of the salmochelin (iro) locus were found in K. pneumoniae (i–iv). Note two of these are typical of structures found in other species (iii in Enterobacter cloacae, iv in Escherichia coli). c Maximum likelihood phylogenetic trees inferred from iuc and iro sequence types (AbSTs and SmSTs) identified in K. pneumoniae genomes. Phylogenetic lineages discussed in the text are labelled and their mobility indicated; nucleotide divergence within and between lineages is given in Additional files 8 and 9. Iro locus structures associated with each lineage are labelled i–iv, as defined in panel b
