Metapneumovirus strains and their use in vaccine formulations and sequences
Provided is an isolated mammalian negative strand RNA virus, metapneumovirus (MPV). Described are isolated mammalian negative strand RNA viruses identifiable as phylogenetically corresponding or relating to the genus Metapneumovirus and components thereof. Also described is mammalian MPV, subgroups and variants thereof, and genomic nucleotide sequences of different isolates of mammalian metapneumoviruses, in particular human metapneumoviruses. The use of the sequence information of different isolates of mammalian metapneumoviruses for diagnostic and therapeutic methods is provided. Nucleotide sequences encoding the genome of a metapneumovirus or a portion thereof, including both mammalian and avian metapneumovirus are described. Also provided are chimeric or recombinant viruses encoded by said nucleotide sequences and chimeric and recombinant mammalian MPV that comprise one or more non-native or heterologous sequences.
1. An isolated antibody, wherein the antibody binds specifically to a protein consisting of the amino acid sequence of SEQ ID NO:366.
2. A method of detecting a mammalian metapneumovirus in a sample, wherein the method comprises contacting the sample with the antibody of claim 1 .
3. The antibody of claim 1 , wherein the antibody is a polyclonal antibody, a monoclonal antibody, a multispecific antibody, a human antibody, a humanized antibody, a chimeric antibody, a single chain antibody, a Fab fragment, a F(ab′) fragment, a fragment produced by a Fab expression library, an anti-idiotypic (anti-Id) antibody, or an epitope-binding fragment.
4. The antibody of claim 1 , wherein the antibody is a human antibody or a humanized antibody.
5. A kit for the detection of MPV, comprising in one or more containers an antibody of claim 1 , 3 or 4 .
6. The kit of claim 5 , further comprising means to detect the antibody.
