The immunogenicity of PRV ΔgE/TK/UL49.5 in mice. (A) Neutralizing antibody titer in serum of immunized mice. (B) The expression levels of cytokines IFN-γ in peripheral serum of immunized mice were detected by ELISA 21 days after booster immunization. (C) The expression levels of cytokines IL-4 in peripheral serum of immunized mice were detected by ELISA 21 days after booster immunization. Data was presented as mean ± SD.* p < 0.05, ** p < 0.01
