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

Figure 1

Effects of pH on fimA (black column), fimB (white column), and fimE (gray column) expression as determined with luxABCDE transcriptional fusions in strain NU149. RLU/CFU were measured with a luminometer and then divided by viable counts; means ± standard deviations are indicated from at least three separate runs.
