Challenge of mice with UPEC 35218. Two weeks after the last immunization, the bladders of mice (n=5) infected with 1×10⁸ CFU of UPEC isolate. The levels of bladder colonization were determined 48 hours after challenge by plating tissue homogenates. Solid lines show median of colonization levels. Significant differences between groups were determined by Kruskal-Wallis analysis (Dunn's multiple comparison test) and are shown by brackets with asterisk. PBS, phosphate buffered saline. ^*p<0.05 was considered as significant.
