摘要:
The invention provides methods and mass-labeled peptides for use in said methods for quantifying the presence of a one or more viral proteins in a sample of a preparation containing agents which bind to said viral protein, using mass-spectroscopic analyses of the sample and standards containing known amounts of labeled and unlabeled signature peptides, in particular wherein said viral proteins are antigens in a vaccine for porcine circovirus.

摘要:
The present invention relates to novel hemagglutinin H5 proteins, nucleic acids and vectors encoding for those as well as vaccines comprising any of such H5 proteins, nucleic acids or vectors encoding for those H5 proteins. Moreover, the present invention also relates to the medicinal use of any of such compositions in humans and animals, in particular for the treatment and prevention of influenza infections with H5N1 of North African origin.
摘要:
The present invention provides a composition and an improved single dose vaccine against E. rhusiopathiae and an improved single dose vaccine against E. rhusiopathiae and H. parasuis which provides one or more of the following: 1) confers effective immunity against E. rhusiopathiae and/or H. parasuis ; 2) decreases the risk of developing clinical signs of E. rhusiopathiae and/or H. parasuis infection; 3) induces an immune response against E. rhusiopathiae and/or H. parasuis ; and 4) has a DOI against E. rhusiopathiae and/or H. parasuis of at least four months. The composition or E. rhusiopathiae vaccine as well as the combined E. rhusiopathiae-H. parasuis composition or vaccine each includes a bacterial component of inactivated E. rhusiopathiae bacteria and a suitable adjuvant. The combined E. rhusiopathiae-H. parasuis composition or vaccine further includes an amount of H. parasuis antigen. The vaccines can be administered to animals in any conventional manner. The amount of the dose for intramuscular administration is preferably less than 5 ml. The amount of E. rhusiopathiae and/or H. parasuis antigen in each dose should be enough to induce an immune response in the animal receiving the vaccine or composition and will preferably confer effective immunity against and decrease the risk of developing clinical signs resulting from E. rhusiopathiae and/or H. parasuis infection for a suitable duration of immunity.
摘要:
The present invention relates to Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) mutant strains having increased stability; compositions containing the strains or antigens derived therefrom; vaccines containing the strains, including killed, attenuated or subunit vaccines; nucleic acids encoding PRRSV polypeptides, polypeptides encoded by the nucleic acids, including antigenic fragments thereof; antibodies which specifically bind to said polypeptides, and methods making and using thereof.
摘要:
Vaccination methods to control PCV2 infection with different PCV2 subtypes are disclosed. Specifically, a PCV2 subtype a (PCV2a) ORF2 proteins or immunogenic compositions comprising a PCV2a ORF2 protein are used in a method for the treatment or prevention of an infection with PCV2 of a different subtype, the reduction, prevention or treatment of clinical signs caused by an infection with PCV2 of a different subtype, or the prevention or treatment of a disease caused by an infection with PCV2 of a different subtype.

摘要:
The present invention relates to a method for prevention of the transmission of a pathogen of an animal of a first species to an animal of a second species characterized in that antigen of the pathogen of the animal of the first species is used for the immunization of the animal of the second species against the pathogen of the animal of the first species, wherein the administration of said antigen results in the reduction or the absence of the reproduction of pathogen of the animal of the first species in the animal of the second species.
摘要:
The present invention provides novel nucleotides sequences, protein sequences, immunogenic compositions, vaccines, and methods that relate to making and using new porcine parvovirus 5A (PPV5A) that infects, inter alia , domestic swine. The compositions and methods provide for the detection of infections by said new virus, monitoring genetic changes in the viral sequences in wild and domestic animals and herds, and making and using novel vaccines for protecting animals from infection by the virus.
