Short description: Family of viruses


Marseilleviridae
Virus classification e
(unranked): Virus
Realm: Varidnaviria
Kingdom: Bamfordvirae
Phylum: Nucleocytoviricota
Class: Megaviricetes
Order: Pimascovirales
Family: Marseilleviridae
Genera
The typical form of the virions of the Marseilleviridae is, in principle, similar to that of the Mimiviridae.

Marseilleviridae is a family of viruses first named in 2012.[1] The genomes of these viruses are double-stranded DNA. Amoeba are often hosts, but there is evidence that they are found in humans as well.[2][3][4][5] The family contains one genus and four species, two of which are unassigned to a genus.[6][7] It is a member of the nucleocytoplasmic large DNA viruses clade.

Taxonomy

The genus contains the following genera and species:[7]

  • Marseillevirus
    • Marseillevirus marseillevirus
    • Senegalvirus marseillevirus
  • Species unassigned to a genus:
    • Lausannevirus
    • Tunisvirus

Additional species have since been recognized.[1] The first member of this family recognized has been named Acanthamoeba polyphaga marseillevirus. A second member is Acanthamoeba castellanii lausannevirus. Two additional viruses have been isolated but have yet to be named. Another member of this family has been isolated from blood donors.[4] An isolate from insects—Insectomime virus—has also been reported.[8]

The viruses appear to fall into at least 3 lineages: (1) Marseillevirus and Cannes8virus (2) Insectomime and Tunisvirus and (3) Lausannevirus. A sixth potential member of this family—Melbournevirus—appears to be related to the Marseillevirus/Cannes8virus clade.[9]

A seventh virus—Brazilian Marseillevirus—has been reported.[10] This virus appears to belong to a fourth lineage of virus in this family.

Another virus—Tokyovirus—has also been reported.[11]

Another member of this family is Kurlavirus.[12]

In 2017, it was proposed that the family contained the following five lineages:[13]

Lineage A

  • Cannes 8 virus
  • Marseillevirus marseillevirus
  • Marseillevirus shanghai
  • Melbournvirus
  • Senegalvirus
  • Tokyovirus

Lineage B

  • Kurlavirus
  • Lausannevirus
  • Noumeavirus
  • Port-miou virus

Lineage C

  • Insectomime virus
  • Tunisvirus

Lineage D

  • Brazilian marseillevirus

Lineage E

  • Golden marseillevirus

Another putative member of this family is Marseillevirus shanghai. If this virus is confirmed, it would belong to the A lineage.

Structure

Viruses in Marseilleviridae have icosahedral geometries. The diameter is around 250 nm. Genomes are circular, around 372kb in length. The genome has 457 open reading frames.[6]

Genus Structure Symmetry Capsid Genomic arrangement Genomic segmentation
Unassigned Head-Tail T=16 Non-enveloped Linear Monopartite
Marseillevirus Icosahedral Circular

Life cycle

DNA-templated transcription is the method of transcription. Amoeba serve as the natural host.[6]

Genus Host details Tissue tropism Entry details Release details Replication site Assembly site Transmission
Marseillevirus Amoeba None Fusion Lysis Cytoplasm Cytoplasm Diffusion in Water

Genomics

A promoter sequence—AAATATTT—has been found associated with 55% of the identified genes in this virus.[14] Most of these sequences occur in multiple copies.[citation needed]

History

One of the first members of this family was described in 2009.[15] Other members described around then (2007) and since then have been documented.[16]
