Fig. 5From: Determining effects of nitrate, arginine, and ferrous on antibiotic recalcitrance of clinical strains of Pseudomonas aeruginosa in biofilm-inspired alginate encapsulatesRelative fold changes determined by Real-time PCR analysis of mexY gene. Relative fold changes show expression level of mexY gene in treated groups (only amikacin and amikacin + 0.5 mM FeSO4) relative to the untreated (control) group for each strain. Data represent the mean value of three biological replicates and error bars indicate standard deviation. T test: **P < 0.01Back to article page
