  • Publication number: 20100008947
    Abstract: The present invention relates to the characterization of the porcine adenovirus E1 and E4 regions. The complete nucleotide sequence of the genome of porcine adenovirus type 3 (PAV-3), providing the characterization of the PAV3 E1 region, is described herein. 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.
