The results showed that the protein concentration of inflammatory cytokines in both types of mice was significantly increased after BMA8 strain infection, and the expression of cytokines was higher in BALB/c mice, including IL-2, IL-4, IL-6, IL-10, IL-12p70, KC/GRO, IFN-γ and TNF-α (Fig. 2D). Here, IL10 is linked to infection.
