Survival in the presence of hydrogen peroxide. Y. pseudotuberculosis wild-type, Δhfq, and Δhfq+phfq strains were incubated for 10 or 30 min with 100 mM H₂O₂. Bars represent mean percent survival compared to untreated controls, and error bars represent standard errors of percent survival from 3 replicates. Statistical analysis was performed with Student's unpaired t test. Data are representative of 3 independent experiments.
