Fig. 1From: Evaluation of the interaction between polymyxin B and Pseudomonas aeruginosa biofilm and planktonic cells: reactive oxygen species induction and zeta potentialPolymyxin B time-kill curves against Pseudomonas aeruginosa strains. Time-kill curve generated using planktonic and biofilm cells from P1C (a and b) and P9C (c and d) at different polymyxin B concentrations. Results are expressed as log10 (CFU/mL)Back to article page
