Abstract: 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.

Abstract: The present invention provides antibodies that immunospecifically bind to a polypeptide of a mammalian metapneumovirus, compositions comprising said antibodies, and methods for producing such antibodies. In particular, the invention provides monoclonal antibodies that immunospecifically bind to the F protein of human metapneumovirus and that neutralize human metapneumovirus. The invention also provides antibodies that cross-react with both the F protein of a mammalian metapneumovirus and the F protein of a mammalian respiratory syncytial virus and that neutralize both viruses. Further, the invention provides recombinant antibodies, such as humanized antibodies, against mammalian metapneumovirus, and methods for producing such recombinant antibodies. The invention further provides methods for treating, managing, ameliorating symptoms of and/or preventing infections with mammalian metapneumovirus, such as human metapneumovirus.
