Fig. 5From: Cu2+ regulated sulfonamides resistance gene (sul) via reactive oxygen species induced ArcA in a pathogenic Vibrio splendidusFluorescence value of ROS in the presence of Cu2+, NAC or both Cu2+ and NAC. The fluorescence value in cells treated with Cu2+, NAC or both Cu2+ and NAC was compared to that in the control cells at each time point. Data are the means for three independent experiments and are presented as the means ± SD. **, P < 0.01Back to article page
