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

Figure 2

Viable counts of E. coli strain NU149 containing different fim-lux fusions in infected murine bladders and kidneys after 8, 24, 72, and 120 hours after inoculation (hpi). Murine tissues included bladders (black square) or kidneys (white circle) from the ftsZ (a), fimA (b), fimB (c), and fimE (d) fusion cultures. 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.
