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.

同样，利用PCR和SOE技术，获得牛分枝杆菌mpb64-ag85b和mpb64-ag85b-esat-6融合基因，以pCDNA3.1为载体构建了牛分枝杆菌多价组合和多基因融合DNA疫苗：二基因融合(pCDNA3.1-MPB64-Ag85B，简称pCMA)和三基因融合(pCDNA3.1-MPB64-Ag85B-ESAT-6，简称pCMAE)DNA疫苗；二价组合和三价组合(pCA+pCM+pCE6)DNA疫苗，免疫BALB／c小鼠，以牛分枝杆菌BCG免疫组为阳性对照，以pCDNA3.1及PBS免疫组为阴性对照，共免疫3次，每次间隔2周，BCG组仅初免时皮下免疫1次。1免后每周，以原核表达纯化的重组MPB64-Ag85B-ESAT-6蛋白和牛分枝杆菌PPD为包被抗原，以间接ELISA方法检测血清IgG水平及lgG亚类。

Subtilis chromosomal DNA. To the best of our Knowledge, this report is the first time to clone and express promotors from BCG in B.subtilis, and proved that the signal of transcription from BCG can be recognized by B.
