Recovery of FZ-DOC synergy in complemented ΔtolC and ΔacrA mutants. Isobolograms of FZ-DOC interactions in growth inhibition of: a ΔtolC mutant (ΔtolC) and a derived strain containing a plasmid expressing tolC gene (ΔtolC + tolC); b ΔacrA mutant (ΔacrA) and a derived strain containing a plasmid expressing acrA gene and (ΔacrA + acrA). Each data point corresponds to the FIC (ratios of the 90% growth inhibition concentrations in combination vs. alone) for FZ (y axis) and DOC (x axis)
