Abstract  

Objective:Evaluate the immunogenicity of an recombinant fowl-pox virus rFPV-3C-P1-2A-IL-18. Methods:Mice were inoculated with the recombinant FPV(rFPV) rFPV-3C-P1-2A-IL-18 、rFPV-P1-2A-3C vaccine, 282E4 FPV and PBS was set as the control groups.The FMDV specific antibody、number of T subtype 、cytotoxicity of special CTL were detected. Results:Compared with other control groups, the mice inoculated with rFPV-3C- P1-2A-IL-18、rFPV-P1-2A-3C vaccines were induced higher anti-FMDV antibody titer, alarger number of T subtype, and higher cytotoxicity of special CTL. Compared with rFPV-P1-2A-3C vaccine,rFPV-3C-P1-2A-IL-18 can induce larger number of T subtype and higher cytotoxicity of special CTL. Conclusion:It is evident that the recombinant fowl-pox virus rFPV-3C- P1-2A-IL-18 show excellent immunogenicity in mice , thus provide valuable support for further development of FMDV genetic engineering vaccines.
