The positive rates of CD4⁺IFN-γ⁺ and CD4⁺IL-4⁺ T lymphocyte subsets analyzed by flow cytometry. At 21 dpi and 35 dpi, blood samples were collected from mice (n = 3). a The positive rates of CD4⁺IFN-γ⁺ T lymphocyte subset. b The positive rates of CD4⁺IL-4⁺ T lymphocyte subset. Bars represent the mean (± standard deviation) of three replicates per treatment in one experiment. Statistical significance was indicated by *P < 0.05 (significant) compared with control group
