Disclosed herein are recombinant polypeptides derived from FBP1 and FBP2. Also disclosed herein are recombinant expression vectors and recombinant host cells for producing the aforesaid recombinant polypeptides. The recombinant polypeptides are proven to be useful and effective in producing a picornavirus with a type I internal ribosome entry site (IRES), so as to facilitate the preparation of a viral vaccine.

Compositions for prevention of Foot and Mouth Disease (FM D) are provided, comprising an antigen component in the amount equivalent to 0.5-20 ?g FM D virus and an adjuvant component comprising oil, an immunostimulatory oligonucleotide, and a polycationic carrier. Methods of using the composition, as well as the methods of reducing FM D persistence are also provided.

The present invention encompasses FCV vaccines or compositions. The vaccine or composition may be a vaccine or composition containing FCV antigens. The invention also encompasses recombinant vectors encoding and expressing FCV antigens, epitopes or immunogens which can be used to protect animals against FCV infection.

The disclosure provides immunogenic compositions comprising human picornavirus peptides derived from structural proteins of the virus, constructs comprising the peptides, the peptides themselves and their use in the prevention of picornavirus infection and disease. Particular peptides from VP4 and VP1 are disclosed.

The present invention relates to methods and compositions for use in inducing tumor-specific antibody mediated complement-dependent cytotoxic response in an animal having a tumor comprising administering to said animal a composition comprising a replication competent oncolytic virus wherein administration of the composition induces in the animal production of antibodies that mediate a CDC response specific to said tumor.

A method of treating cancer in a subject in need thereof includes administering in situ to the cancer a therapeutically effective amount of a virus or virus-like particle.

Porcine circovirus (PCV2) vaccine compositions comprising a peptide antigen derived from a PCV2 capsid protein are described. In various embodiments, the peptide antigen contains amino acids of the capsid protein from about amino acid 47 to about amino acid 202. In some embodiments, the peptide antigen is optionally linked to an artificial T helper epitope and/or mixed with T helper epitopes derived from the ORF1 and ORF3 proteins of PCV2. Methods of using PCV2 vaccine compositions are also described. In various embodiments, a vaccine composition is used in animals for the prevention of PCV2 infection. In other embodiments, a PCV2 vaccine composition is used as an antigen for diagnosing PCV2 infection.

The present invention relates to methods and compositions for use in inducing tumor-specific antibody mediated complement-dependent cytotoxic response in an animal having a tumor comprising administering to said animal a composition comprising a replication competent oncolytic virus wherein administration of the composition induces in the animal production of antibodies that mediate a CDC response specific to said tumor.

Novel compositions useful as human rhino virus immunogens are provided. The compositions enable a host response to sites normally not recognized by a host.

A Senecavirus A polypeptide generally includes at least a portion of 151-434 of SEQ ID NO:1, amino acids 435-673 of SEQ ID NO:1, or amino acids 674-937 of SEQ ID NO:1. The Senecavirus A polypeptide may be used as a capture antigen in a method or device for detecting antibody that specifically binds to the Senecavirus A polypeptide. The Senecavirus A polypeptide may be used as a immunogen to vaccinate a subject having or at risk of having a Senecavirus A infection.
