MPO and colitis: Moreover, compared with the DSS group, the DAI (Figure 1C) was significantly decreased in the DSS + Sj40 group, the MPO (Figure 2B) activity levels were notably declined in the DSS + Sj20 and DSS + Sj40 groups, and the NAG (Figure 2C) activity levels were remarkably decreased in the DSS + Sj20 group, which suggested that mSjc infection could attenuate DSS-induced colitis activity in experimental mice.
