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.
