Figure 2From: Variation in endogenous oxidative stress in Escherichia coli natural isolates during growth in urineGrowth of twenty-one E. coli belonging to different pathovars and phylogenetic groups. Growth in LB broth (dashed line) and in pooled human urine (complete line). The plotted values are means of 3 independent experiments. OD600, optical density at 600 nm. Strains with exponential phase in urine significantly different are specifically labeled.Back to article page
