Classification

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

ICTVdB Virus Code: 00.110.0.01.001. Virus accession number: 11001001. NCBI Taxonomy ID: 212035.

Name, Synonyms and Lineage

Misnomer Bradfordcoccus in use until identified as virus. Virus is assigned to the genus 00.110.0.01. Mimivirus; presently not assigned to a family.

Virion Properties

Introduction

Size and shape of virus has been determined by electron microscopy.

Morphology

Virions consist of a capsid and fibrils. Virus capsid is not enveloped. Virions resemble small Gram-positive cocci when Gram stained. Capsid is spherical and exhibits icosahedral symmetry. The isometric capsid has a diameter of 300–400 nm. The capsid shells of virions are composed of multiple layers. Capsids appear hexagonal in outline. Evenly dispersed surface projections are distinct fibrils. The length of fibers is 80 nm.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of about 1.36 g cm^–3.

Nucleic Acid

The genome is not segmented and contains a single molecule of circular double-stranded DNA. Complete sequence is 1181404 nucleotides long, has the accession number [AY653733] and encodes 1262 genes. NCBI reference genome accession number is [NC_006450].

GenBank records for nucleotide sequence(s); complete genome sequences.

Lipids

Lipids are absent.

Carbohydrates

Carbohydrates are not found in virions.

Antigenicity

Antigenic determinants may be found on virion surfaces that correspond to 35 KDa polypeptide. Antigenic specificity of the virion can be determined by immunoblotting test.

Biological Properties

Natural Host Range

Viral hosts belong to the Domain Eucarya.

Domain Eucarya Kingdom Protoctistae.

Kingdom Protoctista Division Amoebozoa.

Host Classification VVirus infects Family Amboebidae; Acanthamoeba polyphaga.

The description has been generated automatically from DELTA files.

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses (ICTV) by Dr Cornelia Büchen-Osmond, is written in DELTA. The virus descriptions in ICTVdB are coded by ICTV members and experts, or by the ICTVdB Management using data provided by the experts, the literature or the latest ICTV Report. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations from the encoded descriptions are automatically generated and formatted for display on the Web.
