H&E staining for evaluating pathological injury of the jejunum. Histopathological sections of the jejunum were collected from mice on Days 1, 3, 7, and 15 post-infection. A H&E staining of the jejunum. Magnification, × 200. B Villus length of the jejunum. Villus length and crypt depth of the jejunum were measured using Image-Pro Plus software. C The ratio of villus length/crypt depth. D The intestinal pathology scores. The data were expressed as the mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001 compared with the 0 dpi group; +P < 0.05, ++P < 0.01, +++P < 0.001 compared with the 1 dpi group; &P < 0.05, &&P < 0.01, &&&P < 0.001 compared with the 3 dpi group; #P < 0.05, ##P < 0.01, ###P < 0.001 compared with the 7 dpi group.
