Sensitivity of Edwardsiella piscicida to oxidative stress, iron deficiency, and acid stress. TX01, TX01∆trxH, and TX01∆trxHC were cultured in LB medium and LB agar plates with pH = 7 (normal A), with pH = 5 (B), with 80 μM 2,2′dipyridyl (Dp, C), or with 1 mM H2O2 (D) at 28 °C for 24–48 h. The populations of cultivated bacteria were counted by diluted plate. E TX01 and TX01∆trxH were cultured to early logarithmic phase in normal LB medium, then 5 mM H2O2 were added to the medium, and cell density was measured at different time points by determining absorbance at OD600. Data are the means of three independent experiments and presented as mean ± SEM (N = 3). N, the number of times the experiment was performed. *P < 0.05, **P < 0.01.
