Pathological anatomy of enteritis model mice.

The red dashed lines connect the junction of the ileum and cecum in each group. In the SL1344 group, the liver presented with multiple pale lesions, a friable texture, and rounded edges. While hepatomegaly was also observed in the two poSTM experimental groups, the liver’s appearance in terms of color was similar to that of the Mock group, indicating minimal changes. The gallbladder and spleen in the SAL4365 and SAL4386 groups showed pathological enlargement, with sizes intermediate between those of the SL1344 and Mock groups. The colon of the SL1344 group mice was notably shorter than that of the poSTM experimental groups and exhibited numerous varicella-like nodules, with both the SL1344 and SAL4365 groups presenting with petechial hemorrhages.
