Problems solved by technology

However, in order to prevent the occurrence of sheeppox, sheep in this area must be immunized with live sheeppox vaccine at least once a year, and with the immunization of other diseases, sheep epidemic prevention will take more time and cost more

Abstract

The invention provides an expression vector used for expressing foreign protein in the recombination of goat pox virus. A foreign gene is inserted in the down stream of a VVI1L promoter or a VVP11 promoter in the expression vector, by the homologous recombination with the parent plant of the goat pox virus, 12 recombined sheep pox viruses for expressing the foreign protein are obtained, a flanking sequence in the vector, which can make the homologous recombination with the parent plant of the goat pox virus, is a sheep pox virus G14-STV-44-55 vaccine strain which contains TK gene, IFNR-gamma gene or RR small subunit gene, by utilizing the expression vectors, the recombined goat pox viruses expressing different foreign proteins can be constructed by different methods, and the recombined goat pox viruses can be used as recombined live vector vaccines to prevent and treat diseases and study relations of expression, processing, structure and function of different biological active proteins.

Description

Technical field: [0001] The invention provides an expression vector used for expressing foreign protein in recombinant goat pox virus, which belongs to the field of biotechnology. Background technique: [0002] The development of modern molecular biology has enabled people to manipulate the genes of various organisms, mastered the technology of cloning and recombining DNA in bacterial plasmids, thus greatly expanding the methods for people to make vaccines, and developed a variety of genetic vaccines to prevent and control animals. blight, viral vector live vaccines are one of them. [0003] The ability of poxviruses to provide strong immune protection was deeply understood long ago during the fight against smallpox. Learn that poxviruses are the largest of animal viruses and can be seen under a light microscope. Under an electron microscope, the virus has a brick-shaped appearance. The viral genome is composed of single-molecule double-stranded DNA, with a G+C content of...
