S. aureus and P. aeruginosa develop more biofilm mass in the BAL from smokers compared to non-smokers. a S. aureus biofilm formation at 48 h assessed by a microtiter dish biofilm formation assay (*p < 0.0001, by unpaired t-test). b P. aeruginosa biofilm formation at 48 h assessed by fluorescence intensity of Texas-red conjugated to concanavalin-A (Con A-Texas Red) in relative fluorescent units (RFU) (*p < 0.0001, by unpaired t-test). c Representative surface intensity plot of PAO1 biofilm formation from non-smokers BAL. d Representative surface intensity plot of PAO1 biofilm formation from smokers BAL
