Figure 7

Effects of priA inactivation on sensitivity to oxidative injury. (A-B) B1940, B1940ΩpriA and B1940ΩpriA/priA+ were grown to middle logarithmic phase (0.5 OD600 nm corresponding to about 1 × 109 CFU for both strains) and then exposed for the indicated times to hydrogen peroxide (A) or nitric oxide generator sodium nitroprusside (B) in GC liquid medium with shaking and then viability was determined by recovery of viable bacteria. Data are shown as mean ± standard deviation from three independent experiments, each with triplicate samples. Statistically significant differences between values from B1940 and B1940ΩpriA (asterisks) are declared at a p value < 0.05.
