  • Patent number: 5762938
    Abstract: What is described is a modified vector, such as a recombinant poxvirus, particularly recombinant vaccinia virus, having enhanced safety. The modified recombinant virus has nonessential virus-encoded genetic functions inactivated therein so that virus has attenuated virulence. In one embodiment, the genetic functions are inactivated by deleting an open reading frame encoding a virulence factor. In another embodiment, the genetic functions are inactivated by insertional inactivation of an open reading frame encoding a virulence factor. What is also described is a vaccine containing the modified recombinant virus having nonessential virus-encoded genetic functions inactivated therein so that the vaccine has an increased level of safety compared to known recombinant virus vaccines.

  • Patent number: 5688920
    Abstract: Disclosed and claimed are nucleotides for genes encoding the canine herpesvirus (CHV) gB, gC and gD homologues. These genes encode polypeptides of 879, 459 and 345 amino acids, respectively, which are also disclosed and claimed. The genes are useful as DNA probes or, for preparing PCR primers. The polypeptides are useful in antigenic, immunological or vaccine compositions. The nucleotides can be expressed in any suitable vector system, allowing for production of the polypeptides. Additionally, the vector system containing any or any combination of the nucleotides can be employed in an antigenic, immunological or vaccine composition, such as a poxvirus vector system, e.g., a CHV-vaccinia or avipox virus recombinant, as can the products from expression, i.e., the gB, gC and gD glycoproteins. Antibodies elicited by the glycoproteins or from expression of the vector containing the nucleotide(s) are also useful. Methods for making and using the composition are also disclosed and claimed.

  • Patent number: 5505941
    Abstract: The present invention provides a method for inducing an immunological response in a mammal or avian host to a pathogen by inoculating the mammal or avian host with a synthetic recombinant avipox virus modified by the presence, in a non-essential region of the avipox genome, of DNA from any source which codes for and expresses an antigen of the pathogen. The present invention further provides a synthetic recombinant avipox virus modified by the insertion therein of DNA from any source, and particularly from a non-avipox source, into a non-essential region of the avipox genome.

  • Patent number: 5453364
    Abstract: What is described is a modified recombinant virus for expressing a gene product in a host. The modified recombinant virus has host range genes deleted therefrom so that the virus has restricted replication in the host. The modified recombinant virus also contains DNA which codes for and expresses the gene product in the host even with restricted replication of the virus in the host. The modified recombinant virus is used in a method for expressing a gene product in a host or in a cell cultured in vitro, and in a vaccine for inducing an immunological response in a host inoculated with the vaccine. What is also described is a selection system for the cloning and expression of open reading frames in poxviruses, particularly vaccinia virus. The selection system is based on a conditional lethal mutant (host range) of poxviruses.
