The relative expression levels of cytokines in the liver, spleen, kidney, intestine, gill, and skin mucus on the 15th day after secondary immunization. (A) the relative expression of IL-1β; (B) the relative expression of IL-4; (C) the relative expression of IL-6; (D) the relative expression of IRF1; (E) the relative expression of IRF3; (F) the relative expression of IRF7; (G) the relative expression of IFN; (H) the relative expression of MX1; (I) the relative expression of TNF-α. Data are presented as mean ± SD and P values were calculated using one-way ANOVA and LSD post hoc tests. * represents p<0.05, ** represents p<0.01.
