| Abstract: | Two recombinant plasmids, pUTA2P1 and pUTAL3CP1, were constructed by inserting structural pro-tein precursor P1-2A and proteinase 3C of foot-and-mouth disease virus (FMDV) into fowl-pox virus (FPV) recombi-nant vectors pUTA-2 and pUTA-16-LacZ respectively, and two recombinant FPVs (vUTA2P1 and vUTAL3CP1) screened by the RT-PCR, IFA assay and Western blotting assay were obtained successfully. Mice injected respectively with rFPVs were induced high level specific anti-FMDV an-tibodies, increasing of T subtypes, and higher cytotoxicities of splenocytes than those of control groups. These results indicated that a new method was used to construct a poten-tial candidate vaccine of FMDV. |
