Fig 4. Antibacterial activity of antibiotics and cationic polymers (Qn-prAP) against A. baumannii.
(A) Actively growing and (B) stationary phase cells. ~106 CFU mL-1 of bacteria in BM2 media were treated with compounds for 2 h at a concentration of 10 μg mL-1. Stars represent no survival detected (limit of detection < 50 CFU/mL).
