Phage–antibiotic combinational therapy in vitro. (A) Combination therapy on solid agar, P. aeruginosa PA16 plated (A₁) with antibiotic (30 μg/ml GMN), (A₂) with PIAS (∼2 × 10⁸ pfu), and (A₃) with PIAS (∼2 × 10⁸pfu) and antibiotic (30 μg/ml GMN). (B–E) The graphs show the single and combined effects of phages and antibiotics on cell growth as compared to the non-treated cells. The PIAS (∼2 × 10⁸pfu) and the following antibiotics: (A) FSF 50 μg/ml, (B) GMN 30 μg/ml, (C) TET 30 μg/ml, and (D) CAZ 30 μg/ml were used for the combinational therapy.
