FIG. 6.

Bacterial numbers (log CFU/g) present in the urine, bladder, and kidneys of mice coinfected with wild-type strain UCB34 (♦) and isogenic iha mutant QT686 (▴). Data points represent bacterial adjusted counts (normalized with the input ratio) from tissues and urine isolated from different mice. Horizontal bars represent the means. Numbers near the log 0 limit indicate samples in which no bacteria where detected. n indicates the number of tissue or urine samples harvested from the 15 mice (urine samples were available for only 10 mice). Statistical analysis was done using the Wilcoxon matched-pairs test. P values represent statistical significance between the wild type and the mutant in each sample.
