2. Fig. 1
Box-plot of the production levels of quorum-sensing-related virulence factors in culture supernatants from 56 non-clonal clinically pathogenic isolates of Pseudomonas aeruginosa and comparison with laboratory reference strains PAO1 and PA103. Logarithmic scales are used. Dotted lines show the relative levels of production of reference strains PAO1 and PA103. (a) Elastase production as assessed by elastin Congo red assay, expressed as OD495/OD600. (b) Pyocyanin production as assessed by absorbance in an acidic solution expressed as OD520/OD600.

3. Fig. 2
Production of autoinducers (a) N-3-oxododecanoyl-L-homoserine lactone (C12-HSL) and (b) N-butanoyl-L-homoserine lactone (C4-HSL) in culture supernatants from 56 non-clonal clinically pathogenic isolates of Pseudomonas aeruginosa and comparison with laboratory reference strains PAO1 and PA103. Results are expressed in μmol/L on logarithmic scales.
