Classification

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

ICTVdB Virus Code: 02.066.0.02.001. Virus accession number: 66002001. Obsolete virus code: 66.0.2.0.001; superceded accession number: 66020001.

Name, Synonyms and Lineage

Virus is the type species of the genus "T1-like viruses"; family 02.066. Siphoviridae; order 02. Caudovirales.

Virion Properties

Morphology

Phages consist of a head and a tail and are not enveloped. Phage has a head with icosahedral symmetry and a tail with helical (tail) and icosahedral (head) symmetry. The head is isometric and has a diameter of 60 nm. Capsids appear hexagonal in outline. The capsid consists of 72 capsomers. The tail is non-contractile; is filamentous; is cross-banded with a length of 150 nm; width of 8 nm. Tail has fibers; fibers are short; fibers are terminal and subterminal.

Nucleic Acid

The Mr of the genome constitutes 54% of the virion by weight. The genome is not segmented and contains a single molecule of linear double-stranded DNA. The complete genome is 48836 nucleotides long. The DNA is fully sequenced, complete sequence is 48836 nucleotides long. Sequence has the accession number [AY216660], and the NCBI reference genome has the accession number
[NC_005833]. The genome has a guanine + cytosine content of 52 %. Double stranded DNA is non-permuted; the genome sequence has termini with cohesive ends.

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Bacterial Virus Subcommittee at the meeting in Jerusalem, August 1996, to create a new taxon. The proposal has been approved at the meeting of the Executive Committee in Strasburg, 1997, the taxon has been designated as Species (in the genus "T1-like viruses").

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.
