Lm infection significantly increases CD8⁺ BT_RM populations at d29 p.i. Male C57BL/6J mice were infected with 2.0 × 10⁵ CFU Lm EGD and treated with antibiotics. Control mice were uninfected, but treated with antibiotics. Mice were euthanized 29d p.i. and brains were harvested. a Cell populations were measured by FACS. b Each symbol represents an individual mouse, p value calculated by Mann-Whitney U test. c–h Histograms from representative mice show distributions of isotype-stained cells (no fill) and gated CD8⁺ T_RM (gray fill). Mean (± SD, n 4–9) percent marker positive cells are given
