Abstract: Disclosed herein are embodiments of an immunogenic composition for porcine epidemic diarrhea virus, and a method for making the immunogenic composition. Also disclosed is a method for administrating the immunogenic composition to a subject in need thereof. The immunogenic composition comprises PEDV proteins and/or antigens from one or more strains of PEDV, and may additionally comprise proteins and/or antigens from one or more additional porcine pathogens, such as PRRSV. Additionally disclosed in a combination comprising a PEDV immunogenic composition as disclosed herein, and an immunogenic composition or other therapeutic composition directed toward an additional porcine pathogen.

Abstract: Disclosed herein are embodiments of a method for collecting, extracting or eluting proteins and antigens from cells infected with coronavirus. The coronavirus may be a porcine coronavirus, such as porcine epidemic diarrhea virus (PEDV) or porcine delta coronavirus (PDCoV). Also disclosed are embodiments of a composition comprising the coronavirus proteins and antigens, and embodiments of a method of using such a composition. Applications for the composition include, but are not limited to, use in the preparation of antibodies against the proteins and antigens, use as reference markers for coronavirus proteins, and/or use in an immunogenic composition, such as in a vaccine composition.

Abstract: The disclosure includes compositions and methods for the production of an immune response against porcine reproductive and respiratory syndrome (PRRS) virus, or PRRSV. The disclosure is based in part on the use of two or more peptide domains, each with a different sequence, from the PRRSV GP5 protein ectodomain. Compositions and methods comprising polypeptides containing the two or more domains, or nucleic acids encoding them, are described.

Abstract: The invention provides methods, devices, and kits for the detection of a class of porcine reproductive and respiratory syndrome (PRRS) virus, or PRRSV, in a biological fluid. The invention is based in part on an agent which binds the nucleocapsid (N) protein of PRRSV. The agent may be an antibody that binds the N protein with specificity. Compositions and devices comprising the binding agent, as well as methods of using it are also provided. Also provided are methods of preparing devices and kits for the practice of the methods.

Abstract: This invention provides kits, devices, and methods for the detection of antibodies that recognize one or more proteins and/or antigens from porcine reproductive and respiratory syndrome virus (PRRSV). The antibodies may be in a biological fluid of a PRRSV infected or at risk subject. The invention may be advantageously applied to both the diagnosis and prevention of PRRSV infection.
