“…This bacterial species is constituted by five phylogroups [ 7 ], four of which have a high degree of genomic conservation (clades 1, 2, 4 and 5), while the genetically diverse group 3 (PA7 group) has been defined as an outlier clade due to its high genetic sequence variability [ 7–9 ]. This group has recently been proposed to constitute a separate bacterial species [ 10 ]. However, strains belonging to any of the five P. aeruginosa phylogroups are potentially pathogenic even if isolated from environmental samples and show high conservation of strategies and traits involved in establishing pathogenic interactions [ 7, 9, 11 ].…”
