Zamilon, a novel virophage with Mimiviridae host specificity. [PDF]

open access: yesPLoS ONE, 2014
Virophages, which are potentially important ecological regulators, have been discovered in association with members of the order Megavirales. Sputnik virophages target the Mimiviridae, Mavirus was identified with the Cafeteria roenbergensis virus, and ...

Analysis of virus genomes from glacial environments reveals novel virus groups with unusual host interactions [PDF]

open access: yesFrontiers in Microbiology, 2015
Microbial communities in glacial ecosystems are diverse, active, and subjected to strong viral pressures and infection rates. In this study we analyse putative virus genomes assembled from three dsDNA viromes from cryoconite hole ecosystems of Svalbard ...

Viral dynamics in a high-rate algal pond reveals a burst of Phycodnaviridae diversity correlated with episodic algal mortality [PDF]

open access: yesmBio
This study explores virus-host dynamics in a unique environment: an industrial high-rate algal pond (HRAP). A wealth of novel DNA algal viruses are revealed, including members of Nucleocytoviricota “giant viruses” and the enigmatic Preplasmiviricota (e.g.

Evolutionary Dynamics of Giant Viruses and their Virophages [PDF]

open access: yesEcology and Evolution, 2013
Giant viruses contain large genomes, encode many proteins atypical for viruses, replicate in large viral factories, and tend to infect protists. The giant virus replication factories can in turn be infected by so called virophages, which are smaller ...

Virophages of Giant Viruses: An Update at Eleven [PDF]

open access: yesViruses, 2019
The last decade has been marked by two eminent discoveries that have changed our perception of the virology field: The discovery of giant viruses and a distinct new class of viral agents that parasitize their viral factories, the virophages.

A systematic approach to cancer: evolution beyond selection. [PDF]

open access: yesClinical and Translational Medicine, Volume 6, Issue 1, December 2017., 2017
Cancer is typically scrutinized as a pathological process characterized by chromosomal aberrations and clonal expansion subject to stochastic Darwinian selection within adaptive cellular ecosystems.

Complex transcriptional regulations of a hyperparasitic quadripartite system in giant viruses infecting protists [PDF]

open access: yesNature Communications
Hyperparasitism is a common pattern in nature that is not limited to cellular organisms. Giant viruses infecting protists can be hyperparasitized by smaller ones named virophages.

Genome diversity of marine phages recovered from Mediterranean metagenomes: Size matters. [PDF]

open access: yesPLoS Genetics, 2017
Marine viruses play a critical role not only in the global geochemical cycles but also in the biology and evolution of their hosts. Despite their importance, viral diversity remains underexplored mostly due to sampling and cultivation challenges.

Large-scale invasion of unicellular eukaryotic genomes by integrating DNA viruses. [PDF]

open access: yesProc Natl Acad Sci U S A, 2023
Eukaryotic genomes contain a variety of endogenous viral elements (EVEs), which are mostly derived from RNA and ssDNA viruses that are no longer functional and are considered to be “genomic fossils.” Genomic surveys of EVEs, however, are strongly biased ...

Acanthamoeba polyphaga mimivirus Virophage Seroconversion in Travelers Returning from Laos

open access: yesEmerging Infectious Diseases, 2012
During January 2010, a husband and wife returned from Laos to France with probable parasitic disease. Increased antibodies against an Acanthamoeba polyphaga mimivirus virophage indicated seroconversion. While in Laos, they had eaten raw fish, a potential
