Mimivirus and its Virophage

Annual Review of Genetics, 2009
Mimivirus, a virus infecting amoebae of the acanthamoeba genus, is the prototype member of the Mimiviridae, the latest addition to the family of the nucleocytoplasmic large DNA viruses, already including the Poxviridae, the Iridoviridae, the Asfarviridae, and the Phycodnaviridae.

Virophages or satellite viruses?

Nature Reviews Microbiology, 2011
It has been argued that the smaller viruses associated with giant DNA viruses are a new biological entity. However, Mart Krupovic and Virginija Cvirkaite-Krupovic argue here that these smaller viruses should be classified with the satellite viruses.

The dual lifestyle of genome‐integrating virophages in protists

Annals of the New York Academy of Sciences, 2019
AbstractDNA viruses with efficient host genome integration capability were unknown in eukaryotes until recently. The discovery of virophages, satellite‐like DNA viruses that depend on lytic giant viruses that infect protists, revealed a genetically diverse group of viruses with high genome mobility.

Sputnik, a Virophage Infecting the Viral Domain of Life

2012
This chapter discusses the astonishing discovery of the Sputnik virophage, a new virus infecting giant viruses of the genera Mimivirus and Mamavirus. While other virophages have also since been described, this chapter focuses mainly on Sputnik, which is the best described.

Virophage replication mode determines ecological and evolutionary changes in a host-virus-virophage system

AbstractGiant viruses can control their eukaryotic host populations, shaping the ecology and evolution of aquatic microbial communities. Understanding the impact of the viruses’ own parasites, the virophages, on their control of microbial communities remains a challenge. Most virophages have two modes of host infection and replication.

[Prediction of Promoter Motifs in Virophages].

Bing du xue bao = Chinese journal of virology, 2015
Virophages have crucial roles in ecosystems and are the transport vectors of genetic materials. To shed light on regulation and control mechanisms in virophage--host systems as well as evolution between virophages and their hosts, the promoter motifs of virophages were predicted on the upstream regions of start codons using an analytical tool for ...

Biggest Known Virus Yields First-Ever Virophage

Microbe Magazine, 2008
A newly discovered mammoth mimivirus is itself unexpectedly infected with a tiny icosahedral virus, according to Bernard La Scola and Didier Raoult of the Universite of Mediterranee in Marseille, France, and their collaborators in France and the United States.
