  • Publication number: 20080292653
    Abstract: Classical swine fever virus is a world-wide distributed highly-contagious disease affecting swine. The two main strategies for diseases control are prophylactic vaccination and non-vaccination stamping out policies. Marker vaccines are a promising strategy. Here we report the rational development of a doubly antigenic marker CSFV experimental live attenuated candidate strain vaccine (Flag/T4 virus). Flag/T virus (Flag/T4v) is based in the combination of two Brescia derived recombinant attenuated viruses: RB-C22 and T4. RB-C22v contains a 19mer insertion in the structural glycoprotein E1, while T4v posses mutated CSFV amino acid residues 830 to 834 in the structural glycoprotein E2, deleting the highly conserved epitope recognized by monoclonal antibody (mAb) WH303. Flag/T4 virus contains a positive foreign antigenic marker, due to the insertion of the highly antigenic epitope Flag in the 19mer insertion of E1, as well as a negative antigenic marker, the lack of reactivity with mAb WH303.

  • Patent number: 6808916
    Abstract: The present invention is directed to a method of extracting virus, particularly reovirus, from a culture of cells. Infectious virus can be extracted from the culture with a detergent at a convenient temperature such as 25° C. or 37° C. to produce high virus titers. Both ionic and non-ionic detergents can be used in the present invention.

  • Patent number: 6803041
    Abstract: A vaccine for protecting a horse against diseases associated with EHV-1 and/or EHV-4 is provided. The vaccine commonly includes inactivated EHV-1 (e.g., chemically inactivated EHV-1 KyA virus) and an adjuvant. The adjuvant can include a cross-linked olefinically unsaturated carboxylic acid polymer which may have bioadhesive properties. The vaccine may also include antigens against other equine pathogens such as inactivated EHV-4 and inactivated A1 and/or A2 strains of equine influenza virus. Methods for protecting horses against diseases associated with EHV-1 and/or EHV-4 and methods of producing the equine herpesvirus vaccine are also provided.

  • Patent number: 6800432
    Abstract: A method and apparatus for inactivating viruses in a body fluid. A mixture including a therapeutically effective amount of methylene blue and an amount of a body fluid is formed in a container under sterile conditions and then the container is irradiated with a light field of a suitable intensity and wavelength for activating the methylene blue for a time sufficient to inactivate viruses in the mixture. The mixture is maintained in a substantially static state within the container.

  • Patent number: 6720136
    Abstract: Methods of inactivating contaminants of a biological matrix are disclosed. The methods include the steps of: (a) contacting a biological matrix with an inactivating agent including an aziridino moiety, where a portion of the agent reacts with and inactivates the contaminant, and a portion of the agent remains unreacted; (b) contacting the product of step (a) with a solid support including at least 1 quenching moiety attached to the solid support through covalent bonds, under conditions and for a time sufficient to allow the unreacted agent to bond covalently to the quenching moiety; and (c) separating the solid support and the unreacted agent from the biological matrix, where the unreacted agent is attached to the solid support through covalent bonds.

  • Patent number: 6705556
    Abstract: The White Spot Syndrome Virus (WSSV) is a virus affecting shrimps as well as other crustaceans, and the WSSV epidemic poses a serious threat to the shrimp farming industry. The present invention relates to compositions and methods for inducing tolerance and/or immunity to White Spot Syndrome Virus infections. In one embodiment, the invention provides for a tolerine composition based on inactivated viral particles. In another embodiment, the invention provides for a method for inducing tolerance/immunity in shrimps by exposing larval shrimps to the tolerine composition. In yet another embodiment, the invention provides for tolerine composition with improved purity.

  • Patent number: 6660272
    Abstract: The invention relates to new porcine circovirus strains isolated from pulmonary or ganglionic samples obtained from farms affected by the post-weaning multisystemic wasting syndrome (PMWS). It relates to purified preparations of these strains, conventional attenuated or inactivated vaccines, recombinant live vaccines, plasmid vaccines and subunit vaccines, as well as reagents and diagnostic methods. It also relates to the DNA fragments which can be used for the production of subunits in an in vitro expression vector or as sequences to be integrated into a virus or plasmid type in vivo expression vector.

  • Patent number: RE39494
    Abstract: The invention relates to a method for making an inactivated vaccine of Mycoplasma hyopneumoniae by inactivating the bacteria with Thimerosal. The resulting bacterin is mixed with an adjuvant of aluminum hydroxide and DEAE dextran and injected into pigs. The resulting bacterin and adjuvant mixture can also be mixed with other bacteria such as Bordetella and Pasteurella, for further adjuvant effect. Protective immunity against mycoplasmal pneumonia is elicited in swine using these vaccines.
