Concatenated phylogenetic tree showing the molecular evolutionary relationships of the seven genes analysed (acsA, aroE, guaA, mutL, nuoD, ppsA and trpE) between the studied clinical Pseudomonas aeruginosa isolates. The antibiotic profile is indicated in the figure: the MDR isolates are labelled in bold and the XDR isolates are indicated in bold and underlined. Clinical strains PaC7 and PaC16 are not included in the phylogenetic tree. Asterisk mark (*) indicates the new sequence types described in this study.
