Efficiency of the lytic activity of the phage vB_PaeS_VL1 against three different clinical isolates of MDR P. aeruginosa. (a) The P. aeruginosa strains MDR PA897, (b) MDR PA269 or (c) MDR PA294 were cocultured with the phage vB_PaeS_VL1 at different MOIs (i.e., MOI of 1, 10 and 100) and incubated at 37 °C. Every 1 h for 6 h, bacterial growth was measured by optical density measurement. Bacterial culture without phages was included as a control. Data are presented as mean ± SD of three independent experiments. The asterisks indicate significant differences (*P < 0.05, one-way ANOVA followed by Dunnett's post hoc test) between the experimental and control groups.
