  • Patent number: 5650153
    Abstract: There is provided a recombinant Marek's disease virus comprising the genomic DNA of an attenuated Marek's disease virus and a foreign gene from another source. The present recombinant virus can advantageously be used as an active ingredient for a multifunctional live vaccine, exhibiting not only the antigenicity and immunogenicity of the Marek's disease virus but also the properties ascribed to the foreign gene. Since the suitable host cell for the recombinant virus of the present invention is an avian cell which is available in a large quantity and not expensive, the recombinant virus of the present invention can be produced efficiently at low cost on a commercial scale.

  • Patent number: 5486473
    Abstract: There is disclosed a DNA which codes for an antigen comprising at least part of an amino acid sequence of the antigen of a flavivirus, which part contains at least one epitope of the flavivirus antigen. The present DNA can be used for producing the antigen easily and safely at low cost by means of recombinant DNA technique. The antigen produced using the present DNA can be used as an effective vaccine and diagnostic for Japanese encephalitis.
