The end of the reign of a “master regulator’’? A defect in function of the LasR quorum sensing regulator is a common feature of Pseudomonas aeruginosa isolates

5 Feb 2024

Abstract excerpt

ABSTRACT Pseudomonas aeruginosa , a bacterium causing infections in immunocompromised individuals, regulates several of its virulence functions using three interlinked quorum sensing (QS) systems ( las , rhl , and pqs ). Despite its presumed importance in regulating virulence, dysfunction of the las system regulator LasR occurs frequently in strains isolated from various environments, including clinical...
