^aEach strain used was grown in MRS broth for 24 h at 37°C. 

^bViable cells of each strain at an inoculum (L. casei Shirota, 1.8 × 10⁸ CFU; L. fermentum, 1.0 × 10⁸ CFU; L. jensenii, 1.0 × 10⁸ CFU; L. plantarum, 2.2 × 10⁸ CFU; L. reuteri, 1.9 × 10⁸ CFU) were instilled intravesically on day −1, and the mice were infected with E. coli strain HU-1 (2 × 10⁶ CFU) intravesically on day 0. Mice were dissected 24 h after the infection. The antimicrobial activity of each Lactobacillus strain is expressed as the log₁₀ difference in the bacterial count, calculated as the log ₁₀ number of E. coli bacteria in the bladders of mice pretreated with saline minus the log₁₀ number of E. coli bacteria in the bladders of mice pretreated with Lactobacillus strains. Six mice per group were used. ∗, P < 0.05. 

^cDetermined as described in Materials and Methods.
