Plate counts of (a) S. Typhi 733 and (b) S. Typhi Ty2 in distilled water at pH 7.0, 30°C stored in a copper vessel and enumerated under aerobic conditions (open circles) and ROS-n conditions (closed circles); (a) S. Typhi 733 and (b) S. Typhi Ty2 in distilled water at pH 7.0, 30°C stored in a glass vessel and enumerated under aerobic conditions (open squares) and ROS-n conditions (closed squares) Error bars represent 95% confidence limits (n = 3). No counts were obtained at 24 h under any conditions. No counts were obtained after 8 h for bacteria kept in water in the copper vessel.
