Effects of BS-Z15 secondary metabolites on cellular immunity (A) (B), and humoral immunity (C) (D)in mice. (A) Effect of BS-Z15 secondary metabolites on T-lymphocyte proliferative in mice (n = 4). (B) Effects of BS-Z15 secondary metabolites on delayed-type hypersensitivity in mice (n = 8–9). (C) Effect of BS-Z15 secondary metabolites on the activity of mouse antibody-producing cells (n = 10). (D) Effects of BS-Z15 secondary metabolites on serum hemolysin levels in mouse cells (n = 10). Bar graphs are expressed as mean ± SEM. P-values of less than 0.05 were considered statistically significant, different letters were considered significant differences, and the same letters were not significantly different
