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

Lineage B

Lineage C

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]
