Temporal Regulation of fim Genes in Uropathogenic Escherichia coli during Infection of the Murine Urinary Tract

Figure 3

Expression of ftsZ (a), fimA (b), fimB (c), and fimE (d) in murine tissues after infection with E. coli strain NU149 as determined with fim::luxABCDE transcriptional fusions after 8, 24, 72, and 120 hours after inoculation (hpi). Murine tissues included bladder (black square) or kidney (white circle). RLU/CFU were measured with a luminometer, background fluorescence subtracted, and then divided by viable counts; median values are indicated. Five to twelve animals per time point were examined where each symbol represents one mouse. The black horizontal bars represent the median values for each time point and tissue.
