Figure 2. Effect of QS dysregulation caused by qteE mutation on P. aeruginosa virulence-related phenotypes.

Levels of (A) 3OC₁₂-HSL, (B) elastase, (C) proteases produced along growth by P. aeruginosa wild type (black lines), qteE (red lines) and rsaL strains (green line) carrying the pBBR1MCS-5 empty vector, or by the qteE strain carrying the pQteE plasmid (pBBR1MCS-5-derived) for the expression of qteE (dashed red line). Values are the means (± standard deviations) of at least three independent experiments.
