Description

Recombinant foot and mouth disease viruses using the O-Manisa strain of foot-and-mouth disease viruses (O-Manisa strain for protection of ME-SA topotype of O serotyp)

The present invention relates to a recombinant foot-and-mouth disease vaccine virus using O Manisa. More specifically, the present invention relates to a recombinant foot-and-mouth disease vaccine virus O Manisa obtained by cloning a whole gene of FM virus O Manisa and deletion of some genes .

Foot and mouth disease (FMD) is a virus-borne disease that infects animals with split hoofs and is characterized by rapid replication and rapid spreading. Due to its economic importance, this disease is classified as an important animal disease by the World Animal Health Organization (OIE), and it is the most important factor in the trade of livestock products between countries.

The foot-and-mouth disease pathogen is a single-stranded bipolar RNA virus that belongs to the genus Piconaviridae and Aphthovirus and has seven different serotypes (A, O, C, Asia1, SAT1, SAT2 , SAT3 type).

Foot and mouth disease viruses are mostly pathogenic. However, it is internationally forbidden to be used as an attenuated vaccine, which has so far been reduced in pathogenicity to foot-and-mouth disease virus, since the pathogenicity is maintained even in the attempts of various researchers such as multiple passages. The use of attenuated virus against foot-and-mouth disease has a problem of restoration of pathogenicity. Also, it is difficult to distinguish it from outbreaks of foot-and-mouth disease virus using live monsoon vaccine.

The inventors of the present invention have been studying to solve the above problems. The inventors of the present invention have already cloned O manisa foot-and-mouth disease virus genome entirely known as a vaccine capable of widely immunizing against various outdoor viruses of O type foot- It is possible to obtain a novel virus vaccine having no pathogenicity by deleting one or more sites selected from the 3A region and the 3B region of the foot-and-mouth disease virus gene. Thus, the present invention has been completed.

Foot-and-mouth disease virus O manisa is the world's most widely used type of vaccine. However, this vaccine is pathogenic to animals, so it is difficult to use it in vaccine cleansing countries when used as a vaccine. Therefore, it is urgent to develop a vaccine that can be safely used in a clean country. Therefore, the whole gene for O Manisa virus is cloned and the virus is genetically manipulated to remove some genes (at least one gene region selected from 3A region and 3B region) And a foot-and-mouth disease vaccine virus in a lactic acid which is a kind of rumen, and can prepare a safe foot-and-mouth vaccine based on this vaccine virus in the future.

As a prior art related to the present invention, Korean Patent Publication No. 2011-0135532, in which the inventor of the present invention has participated as an inventor, describes a virus vector expressing three different siRNA (small interference RNA) for foot-and-mouth disease defense and a foot-and- The present invention relates to a vaccine, and more particularly, to a viral vector prepared by selecting three siRNA nucleotide sequences proven to be effective in 2B and 3C regions, which are the most stable regions of foot-and-mouth disease genes, Which is a foot-and-mouth disease virus vaccine.

However, the present invention and the prior art are different from each other in technical characteristics of the invention, and both inventions are inventions having different compositions.

The development of one type of foot-and-mouth disease vaccine can be accomplished through years of research, even if it is a Sadoc vaccine, because it must go through several processes, including appropriate conditions and virus selection. Even if a vaccine is developed, the virulence of the virus is maintained and caution should be exercised to prevent virus outbreaks in very rigid facilities when large quantities of virus are cultured. These procedures make it difficult to produce foot-and mouth disease vaccines on time and it may be difficult to supply them to animals at the time they are needed.

The present invention provides a viral vaccine that can replace the expressed antigen site by using as a basic vector for the preparation of a vaccine for preventing foot-and-mouth disease, even if it is a foot-and-mouth disease virus.

The present invention relates to a method for producing a novel pathogenicity-free and distinguishable marker virus, which comprises manipulating a gene part of foot-and-mouth disease virus O Manisa, preferably at least one gene region selected from the 3A region and the 3B region among O- 3B, which is known to be a pathogenic part of the animal, is partly deleted but does not affect the proliferation and 3B, which acts as a protein primer required for the replication of foot-and-mouth disease virus, is normally composed of 3 repeats. And to provide recombinant foot-and mouth disease vaccine virus using O Manisa, a disease caused by weakened virulence.

The recombinant foot-and-mouth disease vaccine virus using the foot-and-mouth disease virus O Manisa provided by the present invention is not pathogenic by manipulating a part of the foot-and-mouth disease virus O Manisa, and is more safe than pathogenic virus in disinfectant experiments or anti- . The vaccine virus can also be used to contribute to the production of foot-and-mouth disease vaccines which can be used for the treatment and / or prevention of O-type (ME-SA type) foot-and-mouth disease.

Claims (18)

Recombinant foot-and mouth disease virus vaccine virus O Manisa, which contains a plasmid obtained by deletion or substitution of some gene sites in a plasmid in which whole gene of human foot-and-mouth type O vaccine strain Manisa is inserted. The method according to claim 1,
(PO-manisa-3Ad) obtained by deletion of part of the 3A region in the entire gene region of the foot-and-mouth disease type O vaccine strain Manisa. 3. The method of claim 2,
Wherein the deletion site in the gene 3A region is a 277 to 306 bp region. The method according to claim 1,
(PO-manisa-3B2d) obtained by replacing part of the 3B1 part in the 3B part consisting of the 3B1 part, 3B2 part and 3B3 part and deletion of part of the 3B part in the entire genetic part of foot-and-mouth disease type O vaccine Manisa Foot-and-mouth disease vaccine virus. 5. The method of claim 4,
Wherein the substitution site in the 3B1 region of the gene is 22 to 36 bp, and the deletion site in the 3B2 region of the gene is 37 to 105 bp. The method according to claim 1,
(PO-manisa-3AB2d) obtained by deletion of part of the 3A region and deletion of part of the 3B1 region or deletion of part of the 3B2 region from the 3B region composed of the 3B1 region, 3B2 region and 3B3 region in the whole gene region of foot-and-mouth disease type O vaccine strain Manisa Foot-and-mouth disease virus. The method according to claim 6,
Wherein the deleted region of the gene 3A region is 277 to 306 bp, the substitution region of the gene 3B1 region is 22 to 36 bp, and the deletion region of the 3B2 region is 37 to 105 bp. (1) inserting a whole gene of foot-and-mouth disease type O vaccine strain Manisa into a plasmid;
(2) deletion or substitution of some genes in the whole genes of the foot-and-mouth disease type O vaccine strain Manisa of the plasmid;
(3) a step of infecting the cells with a plasmid in which some of the genes obtained in the step (2) are deleted or substituted for propagation; and a step of propagating the recombinant foot-pupil vaccine virus using O Manisa. 9. The method of claim 8,
A method for producing recombinant foot-and mouth disease vaccine virus characterized by deletion of the 3A region in the entire genes of the foot-and-mouth disease type O vaccine strain Manisa of the plasmid. 10. The method of claim 9,
Wherein the deleted region of the gene 3A region is 277 to 306 bp. 10. The method of claim 9,
Wherein the deletion of the gene 3A region is carried out by PCR using a forward primer of SEQ ID NO: 2 and a reverse primer of SEQ ID NO: 3. 9. The method of claim 8,
Wherein part of the 3B1 part of the 3B part consisting of the 3B1 part, 3B2 part and 3B3 part is substituted or part of the 3B2 part is deleted in the whole genes of the foot-and-mouth disease type O vaccine strain Manisa of the plasmid. 13. The method of claim 12,
Wherein the substitution site in the 3B1 region of the gene is 22 to 36 bp, and the deletion site in the 3B2 region is 37 to 105 bp. 13. The method of claim 12,
