Table of Contents

Classification

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

ICTVdB Virus Code: 00.061.2.07.007. Virus accession number: 61207007. Former virus code: 00.061.0.07.007.; accession number: 61007007.

Name, Synonyms and Lineage

Synonym(s): Chimpanzee foamy virus, human isolate. ICTV approved acronym: SFV-3. Virus is assigned to the genus 00.061.2.07. Spumavirus ; subfamily 00.061.2. Spumaretrovirinae ; family 00.061. Retroviridae .

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Vertebrate Virus Subcommittee Study Group for Retroviridae at the meeting in Washington, DC, April 2001 and Paris, July 2002, to reclassify the position of Type Species. The proposal has been approved at the meeting of the Executive Committee in Paris, 2002, and the taxon has been designated as Type Species .

Virion Properties

Morphology

Virions have a complex construction and consist of an envelope, a nucleocapsid, a nucleoid, and a matrix protein. Virions are enveloped, spherical to pleomorphic in shape and measure 80-100 nm in diameter. The surface projections are distinctive spikes that are densely dispersed evenly covering the surface. The core is spherical. The nucleoid is concentric. Only one type of virus particle is recovered in preparations.

Nucleic Acid

The Mr of the genome constitutes 2% of the virion by weight. The genome is dimeric; not segmented and consists of a single molecule of linear, positive-sense, single-stranded RNA. The complete genome is of one monomer 11000 nucleotides long and has been fully sequenced with the accession number [M74895]. The genome has terminally redundant sequences. The terminally redundant sequences have long terminal repeats (LTR) of about 1500 nt. The 5'-end of the genome has a methylated nucleotide cap with a type 1 sequence of m7G5ppp5'GmpNp. The 3'-terminus has of each monomer a poly (A) tract and a tRNA-like structure that accepts lysin. Each virion contains two copies of the genome in a dimeric configuration.

Proteins

Proteins constitute about 60% of the particle weight. The viral genome encodes structural proteins and non-structural proteins.

Non-Structural Proteins: The virus codes for an RNA-dependent DNA polymerase.

Lipids

Lipids are present and located in the envelope. Virions are composed of 35% lipids by weight. The composition of viral lipids and host cell membranes are similar. The lipids are of host origin derived from plasma membranes.

Carbohydrates

Three percent of the particle weight are attributed to carbohydrates.

Genome Organization and Replication

By itself, genomic nucleic acid is not infectious.

Translation: Replication involves a reverse transcription step.

Biological Properties

Natural Host Range

Virus infects during its life cycle a single type of vertebrate host. Viral hosts belong to the Domain Eucarya.

Domain Eucarya Kingdom Animalia.

Kingdom Animalia Phylum Chordata.

Phylum Chordata Subphylum Vertebrata.

Class Mammalia.

Class Mammalia Order Primates;
Family Hominidae.
