CA 2477235

The present invention relates to recombinant bovine parainfluenza virus (bPIV) cDNA or RNA which may be used to express heterologous gene products in appropriate host cell systems and/or to rescue negative strand RNA recombinant viruses that express, package, and/or present the heterologous gene product. In particular, the heterologous gene products include gene product of another species of PIV or from another negative strand RNA virus, including but not limited to, influenza virus, respiratory syncytial virus, human metapneumovirus and avian pneumovirus. The chimeric viruses and expression products may advantageously be used in vaccine formulations including vaccines against a broad range of pathogens and antigens.

L'invention concerne un ADNc ou un ARN de virus parainfluenza bovin recombinant (bPIV) pouvant être utilisé afin d'exprimer des produits géniques hétérologues dans des systèmes appropriés de cellules hôtes et/ou afin de sauvegarder des virus recombinant à ARN de polarité négative exprimant, englobant et/ou présentant les produits géniques hétérologues. Ces produits géniques hétérologues comprennent, en particulier, des produits géniques d'une autre espèce de virus parainfluenza ou d'un autre virus à ARN de polarité négative, comprenant sans exclusion, le virus influenza, le virus respiratoire syncytial, le métapneumovirus humain et le pneumovirus aviaire. Les virus chimères et les produits d'expression peuvent être avantageusement utilisés dans des formulations de vaccins, y compris dans des vaccins dirigés contre une large gamme de pathogènes et d'antigènes.
