摘要:
Recombinant multivalent non-pathogenic Marek's Disease virus constructs that encode and express both Infectious Laryngotracheitis Virus and Newcastle Disease virus protein antigens, and methods of their use in poultry vaccines.
摘要:
The invention provides a method for producing a continuous cell line capable of supporting the growth of a Marek's disease virus strain comprising infecting or transfecting a cell with a vector comprising a nucleic acid or fragment thereof of a Marek's disease virus strain and culturing said infected or transfected cell or progeny thereof under conditions suitable for the expression of said nucleic acid and propagation of said cell or progeny thereof. Preferably said nucleic acid or fragment thereof comprises a Marek's disease virus glycoprotein gE gene or functional fragment thereof. The invention further provides a method to generate and/or isolate and/or maintain a hypervirulent and/or very virulent, and/or very virulent plus, and/or virulent and/or avirulent Marek's disease virus strain comprising infecting a cell according to the invention with a hypervirulent, and/or very virulent, and/or very virulent plus, and/or virulent and/or avirulent Marek's disease virus strain and culturing said cell under conditions suitable for the propagation of said cell and the generation, maintenance and isolation of said hypervirulent, and/or very virulent, and/or very virulent plus, and/or virulent and/or avirulent Marek's disease virus strain. The invention further provides a method to prepare a vaccine capable of inducing protection against disease, preferably a Marek's disease virus associated disease in an avian comprising culturing a continuous cell according to the invention and harvesting cell culture components therefrom.
摘要:
The present invention relates to a recombinant avian herpes virus, which comprises at least two recombinant nucleotide sequences, each recombinant nucleotide sequence encoding a distinct antigenic peptide, wherein said at least two recombinant nucleotide sequences are inserted into distinct non-coding region of the viral genome chosen among the region located between UL44 and UL45, the region located between UL45 and UL46, the region located between US10 and SORF3, the region located between SORF3 and US2.
摘要:
The present invention relates recombinant viruses and the uses thereof. More particularly, the invention relates to novel recombinant Marek's disease viruses encoding polypeptide(s) of interest, and their use to express or deliver such polypeptides to animals, particularly poultry. The invention is particularly suited to vaccinate poultry against avian pathogens.

The present invention relates to recombinant MDV1 viruses and the uses thereof. The invention is particularly suited to vaccinate poultry against avian pathogens.
摘要:
The present invention provides an avian recombinant herpesvirus modified by the presence of the cDNA encoding the VP2 of the Delaware Variant E strain of IBDV, a subtype of IBDV serotype I strains. The present invention further provides an avian recombinant herpesvirus comprised of the VP2 gene, of which the backbone virus is a Marek's disease vaccine strain, such as herpesvirus of turkeys. A poultry vaccine including the avian herpes recombinant virus described in the present invention can induce in chickens protective immunity against a variety of different subtypes of IBDV.

摘要:
Integrated viral complexes, methods of producing them, and their use as a vaccine against is described. Integrated viral complexes are optionally dried and may be stored at refrigeration tememperatures. Integrated viral complexes include viable virions in intact cell membranes. The host cells are non-viable. The invention is advantageously employed in the context of Herpes virus including Marek's disease virus.
