Distribution of this virus falls under quarantine restrictions. It is recommended to handle this virus at the biocontainment level BSL-3.

Classification

This is a description of an invertebrate or vertebrate virus at the species level with data limited to classification details. If you have primary data on this virus, please submit them to ICTVdB using the online data entry systems or contact the ICTVdB management.

ICTVdB Virus Code: 00.073.0.01.033. Virus accession number: 73001033.
NCBI Taxon Identifier NCBI Taxonomy ID: 60877.

Name, Synonyms and Lineage

ICTV approved acronym: (TONV). Virus is assigned to the genus 00.073.0.01. Alphavirus; family 00.073. Togaviridae; not assigned to an order.

Virion Properties

Morphology

Virions consist of an envelope and a nucleocapsid. During their life cycle, virions have not been observed outside a cellular environment and have a cell-associated cycle. Virus capsid is enveloped (with a tight fitting membrane). Virions are spherical and measure about 70 nm in diameter. Surface projections are distinctive glycoprotein spikes composed of two virus proteins forming heterodimers that cover the surface. Capsid/nucleocapsid is round and exhibits icosahedral symmetry (T=4). The nucleocapsid is isometric and has a diameter of about 40 nm. Capsids appear round.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA. The complete genome is 11530 nucleotides long. The RNA is fully sequenced and partially sequenced, complete sequence is 11530 nucleotides long. Sequenced regions are 184 and 381 nucleotides long. Sequenced genome has the accession number(s)
[AF075254]; [AF023296]; [U94614]. The 5'-end of the genome has a methylated nucleotide cap. The 3'-terminus has a poly (A) tract.

Reference to nucleotide sequence in PubMed: nucleotide sequences; complete genome sequences.

Proteins

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

Biological Properties

Natural Host

Virus infects during its life cycle arthropod and vertebrate hosts. Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Animalia.

Kingdom Animalia
Phylum Arthropoda and Chordata.

Phylum Arthropoda
Subphylum Hexapoda; Class Insecta.

Phylum Vertebrata
Subphylum Vertebrata; Class Mammalia.

Class Mammalia Order Primates, Perissodactyla, and Rodentia.

Transmission and Vector Relationships

Virus is transmitted by a vector.

Vector Transmission:
Virus is transmitted by arthropods, insects.

Geographical Distribution

Geographical distribution of the virus is probably restricted. The virus spreads in North America and South and Central Americas. The virus is known to occur in temperate regions, or subtropical regions, or tropical regions; viral host lives in the atmosphere. The viral host is found in a pristine environment with no signs of human interference, or a undisturbed environment yet with signs of human disturbance; an agricultural environment, or an aquatic environment.
