MICs are for the UPEC isolates before exposure to biocide (P0), after 12 passages in the presence of each biocide (P12), and after 12 passages in a biocide-free environment (C12). Data represent the mean MICs taken from two separate experiments each with four technical replicates. Data in parentheses represent SDs.
