Intracellular concentration of Hoechst 33,342 in the presence of conessine (20 mg/L) and phenylalanine-arginine β-naphthylamide (PAβN) (25 mg/L) in Pseudomonas aeruginosa K767 (PAO1) (a), P. aeruginosa K1455 (PAO1-nalB) (b), and P. aeruginosa K1523 (PAO1-∆mexB) (c). Data were shown as average of two independent experiments. Error bars displayed ±SEM and * indicated significant (P value ≤0.05)
