| Research Abstract |
The aim of this project is the development of a component vaccine which have adjuvanting potential in itself. The strategy for adding adjuvanting property antigens is the use of recombinant protein translated from artificially joined construct of genes. We focused the adhesive property of the heavy chain of Botulinum toxin. Although the adhesion ability indicated to be located on the C-terminal half of the heavy chain, whole sized heavy chain was tested for adhesion ability. Antigen for component vaccine was selected from avian influenza, Newcastle disease virus, Turkey rhinotrachitis and Marek's disease virus. Additionally, we determined MDV gB as the first triat for adjuvanting ability. To obtain recombinant fusion protein (Btx-gB), we construced the gene fragment and ligated with E.coli-expression vector pET32. Antibody production was induced by injections of recombinant proteins into experimental chickens. While, the concentration of anti-gB antibody after injection of recombinant gB was not lower than that of anti-gB andtibody after injection of recombinant-fusion protein Btx-gB.This data indiceated that the Btx-gB fusion protein did not have enough adjuvanting property. Anothr construction should be tested.
