A method for expressing antigens of foot-and-mouth disease virus in insect in vivo by using re-combinant baculovirus is disclosed, which comprises: cloning different genes combination of foot-and-mouth disease virus into baculovirus carrying vector to construct transfer vector, transfecting baculovirus with the transfer vector to proceed DNA recombination, and thus to get recombinant baculovirus, infecting insect host with the recombinant baculovirus, culturing the infected insect host to express the antigens of foot-and-mouth disease virus, and then collecting and purifying the expressed antigens. The preferred genes, baculovirus carrying vector, baculovirus and insect host are selected from P1-2A3C, ORF and VP1 genes of foot-and-mouth disease virus as shown in SEQ ID NO 1., 3 or 5, pVL1393, Bombyx mori Bm-NPV-ZJ8 and larvae or pupa of Bombyx mori, respectively. |
