By use of site mutation strategy and PCR technology, we obtained the gene P12X3C that includes full length P1, 2A, 3C and a part of 2B and 3B and the gene P12X3C3D that includes full length P1, 2A, 3C, 3D and a part of 2B and 3B. After being digested by restriction enzyme respectively, the gene P12X3C and the gene P12X3C3D were cloned into the pcDNA3. 1 and pTARGET expression vector that were digested by the same enzyme. Recombinant plasmids were checked by restriction enzyme analysis and nucleic acid sequencing. Further more, recombinant plasmids were transfected into BHK-21 cells by using lipoid. The proteins of foot-and-mouth disease virus , which were expressed in BHK-21 cells, were confirmed by sandwich-ELISA and fluoroscopy, and the capsid of FMDV was tested by electron microscope. In order to evaluate enhanced immune response of guinea pigs against FMDV, DNA vaccines which were designed to produce viral capsids lacking infectious viral nucleic acid and contained the gene P12X3C and the gene P12X3C3D were injected respectively with FMDV 3D protein which was expressed in Pichia Pastoris Secreted expression System and purified or with pcDNA3. 1/IFN which includes the gene IFN-α of cattle. Subsequently, Recombinant plasmids were injected to cattles with or without pcDNA3. 1/IFN. Anti-FMDV antibodies were detected by ELISA, and the T lymphocyte proliferation response was tested by MTT assay, neutralization antibodies titers were analyzed by micro-neutralization assay.

The fusion DNA fragments of ag85b-mpb64 and ag85b-mpb64-esat-6 were obtained by PCR andSOE technique. Various DNA vaccines were constructed with the pcDNA3.1: fusion of two genes, and of three genes, bivalent combinations and trivalent combinations(pCA+pCM+pCE6). BALB/c mice were vaccinated with this DNA vaccines.The mice injected withBCG were positive control and the mice injected with pCDNA3.1 and PBS were negative control.The mice were immunized 3 times with 2-wk intervals. The animals in group BCG were only inoculatedsubcutaneously with 1×10~6 CFU BCG at initial vaccination. The serum IgG titers and IgG isotype weredetermined using iELISA coated with M. bovis PPD and rMAE protein expressed and depurated inprokaryotic expression system every week.

Together with the cited sequences of other species (cattle, zebu cattle and buffalo), the molecular phylogenetic tree was therefore built to probe phylogenetic relationship between Bovine subfamilies, Total 5 variation sites were examined and two types of mutation, transition and transversion, were observed, with the overage percentage of nucleotide variation of 1.66%. It demonstrated the poverty of polymorphism at exon 5 of GH gene of three bovine species. There was only one missense mutation out of 5 mutation sites which led to the shift between leu and val amino.
结果表明,在雷琼牛、巴州牦牛和巴州蒙古牛中共检测到5个变异位点,核苷酸取代方式仅有转换和颠换,核苷酸平均突变率仅为1.66%,说明这3个牛种GH基因外显子5多态性较为贫乏;5个变异位点中仅有1个为错义突变,导致亮氨酸和缬氨酸的转换,但该突变在牛种中分布有差异。
