H3-T6SS and TepB are involved in oxidative, acid and osmotic stress resistance. a, b and c The viability of mid-exponential phase P. aeruginosa PA14 strains was determined after challenge with 1 mM H₂O₂ (a), pH 4.0 (b) or 2 M NaCl (c) for 30 min. Statistical analyses for the rest of the assays were performed using unpaired two-tailed Student’s t-test. Data represent the mean ± SEM of three biological replicates, each of which was performed with three technical replicates. ***P < 0.001
