Table of Contents

Classification

This is a description of an invertebrate virus at the family level.

ICTVdB Virus Code: 03.104. Virus accession number: 03104FAM.
NCBI Taxon Identifier NCBI Taxonomy ID: 199704.

Name, Synonyms and Lineage

The taxon is a novel virus not yet listed in the current ICTV Report.

Virus is of the order 03. Nidovirales.

Virion Properties

Morphology

Virions consist of an envelope, spikes, and a nucleocapsid. Virus capsid is surrounded by a single layer envelope. Virions are bacilliform. Virions measure 40-60 nm in diameter; 150-200 nm in length. The envelope has surface projections. Surface projections are distinctive peplomers forming a prominent fringe. The nucleocapsid is elongated coiled tubular with helical symmetry and a width of 13-18 nm. Nucleocapsids are coiled tubular structures arranged perpendicular to the ventral axis.

Physicochemical and Physical Properties

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

Nucleic Acid

The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA. The complete genome is 26235 nucleotides long. The RNA is is about 26235 nucleotides long and encodes cystein protease, RNA-dependent RNA polymerase, helicase and metal ion binding domains, nucleoprotein, S glycoproteins.

DELTA - DEscription Language for TAxonomy developed by Dr Mike Dallwitz, Toni Paine and Eric Zurcher, CSIRO Entomology, Canberra, Australia. ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses by Dr Cornelia Büchen-Osmond is written in DELTA. The virus descriptions in ICTVdB are coded by, or using data from experts in the field of virology or members ICTV. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations are automatically generated and formatted for display on the Web from the descriptions in DELTA-format. The description has been generated automatically from DELTA files.
