Survival fitness and virulence of ΔbamB and ΔfabY mutants in vivo. (A) Bacterial counts recovered from the left lung lobes. The infection dose was 5.0 × 10⁶ cells per mouse (black arrow on the y-axis). Mice were infected with the indicated bacterial strains for 16 h. ^*P < 0.05 vs. CFU of PAO1 cells. (B) Survival curves of the C. elegans N2 strain fed with PAO1 (blue), ΔbamB (green), and ΔfabY (black). ^*P < 0.05 vs. the survival rate of the PAO1-fed worms. In each group, 20 worms were used. Statistical significance was determined by log-rank analysis.
