Abstract: Polynucleotide constructs that express an engineered foot-and-mouth disease (FMDV) P1 precursor protein and a non-FMDV TEV protease and methods for safe and efficient recombinant production of FMDV antigens and immunogens. Recombinant production of FMDV antigens avoids the need to culture highly-infectious FMDV, while conventional culture methods for producing FMDV antigens rely on the native FMDV 3C protease which exerts toxic effects on host cells. The inventors have developed a new system that efficiently and safely processes FMDV P1 precursor without the FMDV 3C protease, thus avoiding the toxic effects associated with use of the 3C protease. The invention is also directed to the FMDV antigens and virus-like particles produced by this system as well as to FMDV vaccines, diagnostics and other biologics.

Abstract: The majority of the mortality observed in young pigs occurs between three and five weeks post-weaning for S. suis infections and between four and six weeks post-weaning for H. parasuis and Actinobacillus suis infections. Clinical disease control associated with S. suis, A. suis and H. parasuis has been attempted using antibiotic treatment, by controlled exposure with live organisms, and by vaccination, using either inactivated commercial or autogenous bacterins administered parenterally. A similar lack of protection in very young pigs is observed with various viruses including swine influenza virus, porcine reproductive and respiratory syndrome virus, porcine epidemic diarrhea virus and rotavirus. Disclosed herein is an immunogenic composition comprising inactivated antigens and a mucosal adjuvant.
