Schematic of the treatment protocols. Animals in groups 3 and 4 were treated with 4% DSS (dissolved in drinking water) from day 0 to day 7. For transplanting the Pg, animals in groups 2 and 4 were administrated Pg (1 × 10⁸ CFU in 100 μL) by the intrarectal injection method. Pg was preadministrated three days before day 0 (initiation of 4% DSS treatment) and followed every two days until the end of the examination. Animals were sacrificed (euthanasia) on day 4 for DAI score assessment and day 7 for colon length determination and histological analysis.
