Figure 1. Determining bactericidal concentrations of each tested antibacterial agent.

Figure 1

(a) Killing curves showing bactericidal activity of five different tested antibiotics against clinical MRSA isolate. Concentrations of each antibiotic were selected from 0 to 2048 µg/ml. Symbols; Oxacillin (red diamond), Gentamicin (green square), Rifampicin (yellow triangle), Ciprofloxacin (pink square) and Tetracycline (orange circle). (b) Bactericidal activity of α-MSH (2–160 µg/ml) against clinical MRSA isolate. The killing assay was done in triplicate and repeated on three different occasions. *p value ≤0.001, **p value ≤0.01, ***p value ≤0.05.
