摘要: Salmonella Typhimurium strain expressing the Actinobacillus pleuropneumoniae antigens, ApxIA, ApxIIA, ApxIIIA and OmpA, was previously constructed as a vaccine candidate for porcine pleuropneumonia. This live attenuated (∆lon∆cpxR∆asd)Salmonella delivery host contained vector containing asd. An immunological study of lymphocyte proliferation, T-lymphocyte subsets cytokines in splenocytes mouse model carried out after stimulation with by intranasal inoculation. The splenic proliferation levels IL-4, IL-6 IL-12 inoculated mice were significantly increased, T- B-cell populations also elevated. Collectively, may efficiently induce Th1- Th2-type immune responses.
