摘要:
The present invention relates novel live bovine adenovirus (BAV) expression vector systems in which part or all of one or both of the early region 1 (E1) and early region 3 (E3) genes are deleted and replaced by a foreign gene or fragment thereof and novel recombinant mammalian cell lines stably transformed with BAV E1 sequences, and therefore, express E1 gene products capable of allowing replication therein of a bovine adenovirus having an E1 deletion replaced by a heterologous nucleotide sequence encoding a foreign gene or fragment thereof and their use in production of (antigenic) polypeptides or fragments thereof for the purpose of live recombinant virus or subunit vaccine or for other therapies.

摘要:
The present invention provides novel recombinant mammalian cell lines expressing bovine adenovirus functions. In one embodiment, mammalian cell lines stably transformed with bovine adenovirus E1 sequences express bovine adenovirus E1 gene products and are useful for the replication of bovine adenovirus vectors having deletions and/or insertions in the E1 region. Such vector/cell line combinations are useful for synthesis of recombinant polypeptides, preparation of subunit vaccines, and in gene therapy.

摘要:
The cloning of a novel PCVII viral genome is described as is expression of proteins derived from the PCVII genome. These proteins can be used in vaccine compositions for the prevention and treatment of PCVII infections, as well as in diagnostic methods for determining the presence of PCVII infections in a vertebrate subject. Polynucleotides derived from the viral genome can be used as diagnostic primers and probes.

The complete nucleotide sequence of the genome of porcine adenovirus type 3 (PAV-3) is provided. Methods for construction of infectious PAV genomes by homologous recombination in procaryotic cells are provided. Recombinant PAV viruses are obtained by transfection of mammalian cells with recombinant PAV genomes. The PAV-3 genome can be used as a vector for the expression of heterologous nucleotide sequences, for example, for the preparation and administration of subunit vaccines to swine or other mammals. In addition, PAV-3 vectors can be used for gene therapy and expression of heterologous polypeptides. PAV-3 genome sequences can also be used for diagnostic purposes, to detect the presence of PAV-3 DNA in a subject or biological sample.
