Figure 1: Biofilm formation and planktonic growth of S. aureus IPLA 1 in the presence of different MOIs of bacteriophage phiIPLA-RODI.

(A) Planktonic growth measured as OD600. (B) Viable cell numbers per well present in the planktonic phase. (C) Adhered biomass determined as absorbance at 595 nm (A595) following crystal violet staining. (D) Viable cell numbers per well in the adhered phase (biofilm). All values represent the average and standard deviation of three independent biological repeats. Data obtained in the presence of different phage concentrations were compared to the control samples taken at the same time point. P-values < 0.05 were considered significant (*). Bars missing correspond to bacterial counts below the detection limit (10 CFU/well).
