  • Patent number: 11858962
    Abstract: The present invention relates to recombinantly constructed proteins useful for analytical assays, in particular for determining in a biological sample obtained from an individual the presence of antibodies specific for a rhabdovirus. More particular, the present invention relates to a polypeptide comprising an ectodomain of a rhabdovirus glycoprotein and a heterologous multimerization domain linked to said ectodomain. In one example, a fusion protein of the formula x-y-z is provided, wherein x consists of or comprises such an ectodomain being optionally free of a furin cleavage site, y is a linker moiety, and z is a heterologous multimerization domain optionally selected from the group consisting of immunoglobulin sequence, coiled coil sequence, streptavidin sequence, fibritin sequence, and avidin sequence.

  • Patent number: 10624963
    Abstract: An improved method for recovering the protein expressed by open reading frame 2 from porcine circovirus type 2 is provided. Also provided is recombinant PCV2 ORF2 protein, and immunogenic compositions comprising PCV2 ORF2 protein. Moreover, multivalent combination vaccines are provided which include an immunological agent effective for reducing the incidence of or lessening the severity of PCV2 infection, preferably PCV2 ORF2 protein, or an immunogenic composition comprising PCV2 ORF2 protein, and at least one immunogenic active component of another disease-causing organism in swine.

  • Patent number: 10568955
    Abstract: The present invention relates to the use of an immunogenic composition that comprises a porcine circovirus type 2 (PCV2) antigen for treatment of several clinical manifestations (diseases). Preferably, the clinical manifestations are associated with a PCV2 infection. Preferably, they include lymphadenopathy, lymphoid depletion and/or multinucleated/giant histiocytes. Moreover, the clinical symptoms include lymphadenopathy in combination with one or a multiple of the following symptoms in pigs: (1) interstitial pneumonia with interlobular edema, (2) cutaneous pallor or icterus, (3) mottled atrophic livers, (4) gastric ulcers, (5) nephritis and (6) reproductive disorders, e.g. abortion, stillbirths, mummies, etc. Furthermore the clinical symptoms include Pia like lesions, normally known to be associated with Lawsonia intracellularis infections.
