Fig. 2From: Genome plasticity favours double chromosomal Tn4401b-blaKPC-2 transposon insertion in the Pseudomonas aeruginosa ST235 cloneMaximum likehood phylogenetic tree based on core (a) and accessory (b) genome of the 45 ST235 isolates. The isolates are named as follow: strain name, acronym of the origin country in bold (see Additional file 1: Table S1) and date of identification. The strains that start as AZPAE1 were simplified in the figure as A1. The branches into the tree were established when the sum of all internal nodes were ≤ 2, every branch is show in different colours. The bar scale (1.0 and 0.001) indicate the SNP numberBack to article page
