Minimum inhibitory concentrations (MIC) changes in bacterial strains E. coli XDR CI 1057 (A) and E. coli ML-35p (B) exposed to selection by individual goat cathelicidins ChMAP-28 (MIC value at transfer “1” = 0.125 μM) or mini-ChBac7.5Nα (MIC value at transfer “1” = 8 μM), the synergistic combination of ChMAP-28 + mini-ChBac7.5Nα (MIC value at transfer “1” = 0.03 + 2 μM, respectively), and the reference antibiotic polymyxin B (MIC value at transfer “1” = 0.125 μM). The experiment was performed in the Mueller-Hinton broth supplemented with 0.9% NaCl at 37°C. 26 repeated passages (transfer N) in the presence of antimicrobial agents were made for each bacterial strain during the experiment.
