Fig 5. Th17 responses in SrtA/SCPA immunized mice were resolved promptly following bacterial clearance.

Mice were immunized and challenged as described in Fig 1A and sacrificed on the indicated days after challenge. (A) CFUs in NALT were determined on blood agar plate. Data are means ± SEM (n = 4). (B) Frequencies of IL-17⁺ cells in CD4⁺ NALT cells were determined by flow cytometry. Data are presented as the means ± SEM (n = 6) from two independent experiments. * P ≤ 0.05, ** P ≤ 0.01, *** P ≤ 0.001, Unpaired t-test (A) and Kruskal-Wallis test (B).
