From: Real-time monitoring of Pseudomonas aeruginosa biofilm formation on endotracheal tubes in vitro
Real-time evaluation of biofilm formation on ETT pieces and CFU counts. Box plots of RLU (a) and of CFU/ml (c) of BLI-Pseudomonas biofilm on ETT pieces, untreated (white box plots) or treated (grey box plots) with gentamicin after 12, 24 or 48 h of incubation. Mean +/− SEM of RLU (b) or CFU/ml (d) analysis from 12 different ETT pieces. Circles or squares indicate the ETT pieces untreated or treated with gentamicin, respectively. Each ETT piece in panel b has a different colour: this allows us to follow the development of biofilm over time. Values of p < 0.05 (*), p < 0.01 (**), p < 0.001 (***) and p < 0.0001 (****) were considered significant
