摘要:
The present invention provides bivalent oral vaccines against infectious pancreatic necrosis virus (IPNV) and infectious salmon anemia virus (ISAV). Yeast cells comprise an expression vector comprising (i) a polynucleotide sequence encoding a VP2 capsid protein of IPNV and (ii) a polynucleotide sequence encoding one or more antigenic epitopes of hemaglutinin of ISAV. The yeast cells express sub-viral particles (SVP) comprising a VP2 capsid protein of IPNV and one or more antigenic epitopes of hemaglutinin of ISAV. The yeast cells and SVP may be administered in an effective amount to increase the amount of antibodies against IPNV and ISAV in the fish, preferably Salmonidae. The yeast cells and SVP may be in the form of fish food for administering to the fish orally.

摘要:
Compositions that include Toll-like Receptor 5 agonists and at least a portion of at least one papillomavirus protein, such as a papillomavirus suppressor binding protein, papillomavirus transforming protein and papillomavirus capsid protein, can be employed in methods that stimulate an immune response in a subject, in particular, a protective immune response in a subject. The Toll-like Receptor 5 agonist and papillomavirus protein can be components of a fusion protein, can be associated with at least one particle in a molar ratio no greater than about 1 and can be administered to subjects in relatively low doses.
摘要:
Compositions that include Toll-like Receptor 5 agonists and at least a portion of at least one influenza antigen can be employed in methods that stimulate an immune response in a subject, in particular, a protective immune response in a subject. Compositions can be associated with particles and employed in the methods in relatively low doses to provide protective immunity to viral infection.
摘要:
The invention relates to a polypeptide of a protective antigenic determinant (PAD polypeptide) of porcine reproductive and respiratory syndrome virus (PRRSV) and nucleic acids encoding a PAD polypeptide. The PAD polypeptide and nucleic acids encoding a PAD polypeptide are useful in the development of antibodies directed to PAD, vaccines effective in providing protection against PRRSV infection, and diagnostic assays detecting the presence of PAD antibodies generated by a PAD-specific vaccine. The invention also discloses methods of generating antibodies to PAD, for vaccinating a pig to provide protection from PRRSV infections, a method of preparing the vaccine, a method of treating PRRSV infections in a pig, and a method of detecting antibodies to PAD of PRRSV.
