DNA extraction and sequencing of environmental and hospital isolates of P. aeruginosa was performed at the International Center for Microbial Genomics of Universidad del Bosque based on Illumina technology. The preparation of Nextera XT genomic libraries was carried out from the DNA extracted using the Qiagen DNeasy Blood & Tissue kit according to the manufacturer's instructions. The quality, purity and concentration of the DNA obtained by Nanodrop and Qbic from Thermo Fisher were verified. Whole-genome sequencing was performed using the MiSeq system, and paired sequences were obtained for each isolate with a read length of 2149 bp.
