Abstract
The invention relates to construction and an application of a recombinant herpesvirus of turkey (HVT) for expressing a GB gene of a serum I type Marek's disease virus. The constructed recombinant chimeric herpesvirus of turkey rHVT-GB strain is a recombinant virus obtained by recombining a serum I type MDV GB (glycoprotein B, MDV1-GB) gene expression cassette to HVT; the recombinant virus can be used as a production virus seed for preparation of a Marek's disease vaccine; compared with the HVT, the recombinant virus plays better immune protection role and greatly enhances the immune protective ability to MD; the rHVT-GB recombinant virus strain can be used as a carrier for constructing viruses capable of expressing other avian pathogenic protective antigen genes (such as a newcastle disease virus F gene, an infectious laryngotracheitis GB gene and an infectious bursa of Fabricius VP2 gene) and used for preparation of live vector vaccines for preventing other corresponding poultry diseases.
Description
Technical field
The present invention relates to a kind of structure of the recombinant herpesvirus of turkeys for expressing the type marek's disease virus GB genes of serum I
And its application.Animal biological product field,
Background technology
Chicken Marek's disease (Marek ' s disease, MD), is by chicken Marek's disease virus (Marek ' s disease
Virus, MDV) a kind of chicken Marek's disease (Marek`s Disease, MD) for causing is cause chicken by chicken herpetoviruses one
Most common lymphoproliferative diseases is planted, it is thin with the lymph sample of peripheral nerve, iris, skin, muscle and each internal organs
Born of the same parents' infiltration, hyperplasia and tumour are formed and are characterized.
This disease was found first early in 1907 by Hungarian veterinary pathologist horse Garrick, and was named as horse in 1961
Vertical creutzfeldt jakob disease.There is prevalence each main poultry countries and regions in the present world, are also most important fowl on economic implications in China
One of disease, serious threat and huge economic loss is caused to China's poultry production.
Marek's disease virus (Marek ' s disease virus, MDV) belongs to cell-associated herpesviral B groups.Disease
Poison has two kinds of existence forms, i.e. nude particle (nucleocapsid) and has the complete virus particle of cyst membrane.The former virus nucleocapsid is in six
Angular, a diameter of 85~100nm has strict cell-associated, leaves cytopathic and is remarkably decreased and loses, in the external world
Survival activity is very low in environment, is mainly seen in renal tubule, the bursa of farbricius, nerve fiber and tumor tissues.Most of naked virals
Particle is present in nucleus, occasionally in cytoplasm or extracellular fluid.The latter is primarily present in nuclear membrane nearby or core
In vacuole, 130~170nm of diameter is mainly seen in feather capsule cuticular layer, and majority is the complete virus particle for having cyst membrane, non-thin
Born of the same parents' associativity, can depart from cell and exist, and environmental resistance is strong to external world, is played an important role in terms of the propagation of this disease.
Bulow and Biggs in 1975 is neutralized using indirect immunofluorescence assay, agar gel immune precipitation and virus
MDV and correlated virus (HVT), are divided into three kinds of serotypes by experiment, and subsequent this sorting technique is special by the MDV types that Lee is set up
Specific monoclonal antibodies are confirmed.
Three kinds of serotypes according to MDV, current commercialization MDV vaccines are divided into I weak type CVI988/Rispens plants, nothing of cause
II pathogenic type SB1 plants and FC126 plants of III type herpes turkey virus (Herpesvirus of turkey, HVT).Cause weak I
Type CVI988/Rispens plants good to MD protecting effects, but it is used as strict cell mating type virus, it is necessary to which Liquid nitrogen storage is transported
It is defeated, significantly increase vaccine cost.HVT can freeze preservation, save vaccine cost, but its protection to MD is weaker,
Therefore the immune efficacy for improving HVT is very necessary.The GB genes of the type MDV of serum I are inserted into Ross the TK bases of HVT genomes
Cause, but the recombinant virus multiplication capacity in vivo for building dies down.(Ross LJ,Binns MM,Tyers P,Pastorek J,

Marek's disease.Avian Pathol2004,33(1):59-68.).Therefore, normal proliferative is built and with guarantor higher
The HVT for protecting power is highly desirable to.
Vaccine is one of important means of anti-livestock and poultry processed, and big more important fowl infection all can use corresponding at present
Vaccine makees effective prevention.In order to further reduce production cost, improve product quality, the research of fowl new generation vaccine is compeled in eyebrow
Eyelash.With becoming better and approaching perfection day by day for Protocols in Molecular Biology, to transform viral nucleic acid structure as the vaccine of means, such as gene-deleted strain epidemic disease
Seedling, insertion mutation strain, virus live vector vaccine etc. have obtained great development, and wherein virus live vector vaccine is with production and application side
Just, it is cheap, and security, stability and the aspect advantage, the focus as research such as immunity is stronger.Relative to other diseases
Poisonous carrier (such as fowlpox virus, aviadenovirus, NDV), chicken Marek's disease virus (Marek ' s disease
Virus, MDV) used as most potential vaccine carrier, its advantage for protruding is embodied in:MDV is strict cell mating type disease
Poison, the carrier bacterin of structure is not disturbed by maternal antibody, overcomes the defect of numerous live vector vaccines;MDV molecules are big
The small insertion for being 180kb or so, larger fragment gene being accommodated, the stability without influenceing recombinant virus;MDV vaccines are adapted to
Early immune, the research and development to most virus particularly immunosuppressive virus vaccines bring dawn.Virus is built based on HVT living
