Mice were infected as described above and were euthanised 24-h post infection. The bladders were collected and homogenised in the presence of a protease inhibitor cocktail (Roche). The samples were spun at 12,000 x g for 20 min at 4 °C, and supernatants were stored at −80 °C. Cytokine measurements were performed on 4–9 samples per group using the Bio-Plex Pro Mouse Cytokine 23–Plex Group 1 kit as per manufacturer’s instructions (Bio-Rad).
