Members of the Paramyxoviridae family are enveloped negative-sense RNA viruses, further classified into either the Pneumovirinae
or Paramyxovirinae subfamily (1).
The virus is a member of the family Paramyxoviridae and the subfamily Pneumovirinae
Avian metapneumovirus (aMPV), in the subfamily Pneumovirinae
of the family Paramyxoviridae, is associated with acute respiratory tract infection as well as reductions in egg production in turkeys, chickens, and ducks (1).
To elucidate sequence information from 1 of the 13 isolates, we used a consensus-degenerate hybrid oligonucleotide primer algorithm to design degenerate PCR primers based on highly conserved amino acid sequences within multiple sequence alignments of all viruses in the subfamily Pneumovirinae (3).
MPV is 1 of only 3 virus species classified in the family Paramyxoviridae, subfamily Pneumovirinae, genus Pneumovirus.
Human metapneumovirus (HMPV) is the newest member of the family Paramyxoviridae, in the subfamily Pneumovirinae
, shared with respiratory syncytial virus (RSV) (1).
Human metapneumovirus (hMPV) is a negative-sense, single-stranded, nonsegmented RNA virus of the genus Metapneumovirus of subfamily Pneumovirinae
of the family Paramyxoviridae, a large family of viruses that affect humans and animals (1).
Genetically, its closest relative is the avian pneumovirus type C (1,13,14); however, clinically, it resembles the respiratory syncytial virus (RSV) (15), a common respiratory pathogen classified in the family Paramyxoviridae, subfamily Pneumovirinae
Human metapneumovirus (HMPV) is a member of the subfamily Pneumovirinae
within the family Paramyxoviridae.
Human metapneumovirus (HMPV) is a recently discovered respiratory pathogen of the family Paramyxoviridae belonging to the same subfamily, Pneumovirinae
, as respiratory syncytial virus (RSV) (1,2).
subfamily is classified into Pneumovirus, containing HRSV, and Metapneumovirus genera.
