PtxR modulates the expression of QS-controlled virulence factors in the Pseudomonas aeruginosa strain PAO1.

Molecular microbiology - 1 Aug 2006

Abstract excerpt

The production of several virulence factors by Pseudomonas aeruginosa is regulated through the hierarchical cell-density dependent quorum sensing (QS) systems las and rhl. A third component of the QS hierarchy, the Pseudomonas quinolone signal PQS, also controls the expression of several genes. We previously described P. aeruginosa PtxR as a transcriptional activator of the exotoxin A gene toxA. Here, we provide...
