FIG. 3.

Lesion scores for bladder tissues obtained from U. parvum-inoculated rats: F344 (n = 15), SD (n = 12), LEW (n = 10), and WIS (n = 10). Horizontal bars represent the median value for each rat strain. Parameters for lesion scoring were as follows: density of inflammation (A), total area of the bladder affected (B), and degree of epithelial change (C). Samples were collected from four separate experiments. Lesion scores were analyzed with the Kruskall-Wallis test, and P values are presented within the corresponding graph.
