Relative gene expression of Adh genes in wild-type and mutant strains after treatment with H₂O₂ for 20 min. Comparison of relative gene expression for A. baumannii ATCC 19606 (A) wild-type; (B) Δ3 single mutant; (C) Δ4 single mutant; (D) Δ6 single mutant; (E) Δ34 double mutant; (F) Δ36 double mutant; (G) Δ46 double mutant; and (H) Δ346 triple mutant strains cultured in M9 medium before (gray bar) and after 5 mM H₂O₂ treatment for 20 min (black bar). Two-way ANOVA tests were conducted to assess statistical significance. **** p < 0.0001.
