FIG. 3.

Bladder inflammation scores for inbred mouse strains during the course of E. coli UTIs. Mice were inoculated intravesically with 10⁸ E. coli CFU on day 0 and sacrificed at day 1, 3, 7, or 14. The degree of inflammation over the total area of each section was graded according to the criteria in Table 1. Each point represents the mean inflammation score of 5 or 6 mice. Symbols are as defined for Fig. 1.
