Table of Contents

Classification

This is a description of a vertebrate virus at the subfamily level.

ICTVdB Virus Code: 01.048.2. Virus accession number: 0482SFAM. Obsolete virus code: 48.2.; superceded accession number: 48200000.
NCBI Taxon Identifier NCBI Taxonomy ID: 11244.

Name, Synonyms and Lineage

Virus is of the family 01.048. Paramyxoviridae; order 01. Mononegavirales.

Virion Properties

Morphology

Virions consist of an envelope and a nucleocapsid. Virus capsid is enveloped. Virions are spherical to pleomorphic; filamentous and other forms are common. Virions measure (60-)150-250(-300) nm in diameter; 1000-10000 nm in length. Surface projections are distinctive spikes of haemagglutinin (H) and fusion (F) glycoproteins covering evenly the surface. Surface projections are 11-20 nm long; spaced 6-10 nm apart. Capsid/nucleocapsid is elongated with helical symmetry. The nucleocapsid is filamentous with a length of 600-800(-1000) nm and a width of 18 nm. Pitch of helix is 7 nm.





















3D structure of Pneumovirus, can be found at the University of Warwick, Pneumovirus Laboratory, UK.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.18-1.2 g cm-3.

Nucleic Acid

The Mr of the genome constitutes 0.5% of the virion by weight. The genome is not segmented and contains a single molecule of linear negative-sense, single-stranded RNA. Virions may also contain occasionally a positive sense single-stranded copy of the genome (thus, partial self-annealing of extracted RNA may occur). The complete genome is 15300 nucleotides long.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are present and located in the envelope. Virions are composed of 20-25% lipids by weight. The composition of viral lipids and host cell membranes are similar. The lipids are of host origin and are derived from plasma membranes.

Biological Properties

Natural Host

Virus infects during its life cycle a single type of vertebrate host.
