Fig. 2.

Example images documenting coating activation during the course of one experiment. Columns show example images taken from models infected with distinct bacterial species or devoid of bacteria: No infection – Un-inoculated controls devoid of bacteria. P. mirabilis – Models infected with a P. mirabilis clinical isolate. E. coli – Models infected with an E. coli clinical isolate (non-urease producing species). Rows show example images of bladder models at key time points related to observed coating activation: Model start – Images taken at the start of experiments. For Initial and Strong colour change figures in parentheses provide the average time after model start at which colour change was observed, and the standard error of the mean.
