Abstract excerpt

Pseudomonas aeruginosa is a ubiquitous environmental bacterium and an opportunistic pathogen that represents an important health hazard. The quorum-sensing response regulates the expression of several virulence factors and involves three regulons: Las, Rhl, and Pqs. The P. aeruginosa ATCC 9027 strain, which belongs to the genetically diverse PA7 clade, contains a frame-shift mutation in the pqsR gene that encodes...
