摘要:
The present invention provides novel viral vectors. In one embodiment, the present invention provides mutant and recombinant bovine adenoviruses having a deletion and/or insertion of DNA in the early gene region 4 (E4). In another embodiment, the present invention provides mutant and recombinant bovine adenovirus 1 viruses having a deletion and/or insertion of DNA in the early gene region 3 (E3). The present invention also contemplates the use of the viral vectors for vaccination, gene therapy or other applications as suitable.

摘要:
The present invention relates to a non-naturally occurring, recombinant equine herpesvirus. The invention also relates to a recombinant equine herpesvirus capable of replication which comprises viral DNA from a species of equine herpesvirus and foreign DNA, the foreign DNA being inserted into the equine herpesviral DNA at a site which is not essential for replication of the equine herpesvirus. The invention also relates to DNA encoding the US2 protein of an equine herpesvirus. The invention relates to homology vectors for producing recombinant equine herpesviruses which produce recombinant equine herpesviruses by inserting foreign DNA into equine herpesviral DNA. The invention further relates to a method of producing a fetal-safe, live recombinant equine herpesvirus.

The present invention provides a recombinant fusion protein comprising an antigenic amino acid sequence fused to at least a portion of the gpX glycoprotein from pseudorabies virus. Such a protein may be formulated into a vaccine and delivered to an animal using a live herpesvirus vector adapted to express the fusion protein.

The present invention provides a recombinant, attenuated infectious laryngotracheitis virus comprising the infectious laryngotracheitis viral genome which contains a deletion in the glycoprotein gG gene. This attenuated virus is useful as a vaccine against infectious laryngotracheitis virus.The present invention also provides a recombinant, attenuated infectious laryngotracheitis virus comprising the infectious laryngotracheitis viral genome which contains a deletion in the US2 gene, UL47-like gene, ORF4 gene or glycoprotein g60 gene.The present invention also provides a method for distinguishing chickens or other poultry vaccinated with a recombinant infectious laryngotracheitis virus which produces no glycoprotein gG from those infected with a naturally-occurring infectious laryngotracheitis virus.
摘要:
The present invention discloses attenuated Clostridium perfringens organisms that express a substantially nontoxic alpha-toxin. The expressed alpha-toxin is a deletion mutein that relative to the alpha-toxin of the mature alpha-toxin of Clostridium perfringens strain 13, is missing at least nine consecutive amino acid residues including His68. The present invention also discloses attenuated organisms that encode the muteins, as well as the use of such attenuated organisms as vaccines.
摘要:
The present invention provides isolated and purified DNA encoding feline CD80 (B7-1) ligand, feline CD86 (B7-2) ligand, feline CD28 receptor, or feline CTLA-4 (CD152) receptor, as well as vectors comprising nucleic acid encoding feline CD80, feline CD86, feline CD28, or feline CTLA-4. The present invention provides a host cells transformed with CD80-encoding vectors, CD86-encoding vectors, CD28-encoding vectors, or CTLA-4-encoding vectors. The invention provides polypeptides encoded by the nucleic acid of feline CD80, feline CD86, feline CD28, or feline CTLA-4. The present invention provides a vaccine comprising an effective amount of polypeptides encoded by the nucleic acid of feline CD80, feline CD86, feline CD28, or feline CTLA-4. The present invention also provides vaccines which further comprise immunogens derived from pathogens. The invention provides for vaccines capable of enhancing an immune response. The invention also provides for vaccines capable of suppressing and immune response.
