Biofilm eradication activity of the phage vB_PaeS_VL1 against clinical isolates of MDR P. aeruginosa. The viable bacterial cell counts in 48 h-old biofilms of P. aeruginosa strains (a) MDR PA897, (b) MDR PA269 or (c) MDR PA294 after treatment with phage VL1 for 6, 12 and 24 h were measured using the standard plate count. The total biofilm mass of 48 h-old biofilms of P. aeruginosa strains (d) MDR PA897, (e) MDR PA269 or (f) MDR PA294 after treatment with phage VL1 for 6, 12 and 24 h. The absorbance of each well was measured at 595 nm after a crystal violet stain. Data are presented as mean ± SD of three independent experiments. ****P < 0.0001, ***P < 0.001, **P < 0.01 or *P < 0.05, Students t test, indicates statistically significant differences between experimental and control groups.
