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

A Large Open Pangenome and a Small Core Genome for Giant Pandoraviruses [PDF]
Frontiers in Microbiology, 2018 Giant viruses of amoebae are distinct from classical viruses by the giant size of their virions and genomes. Pandoraviruses are the record holders in size of genomes and number of predicted genes. Three strains, P. salinus, P. dulcis, and P.

Polintons: a hotbed of eukaryotic virus, transposon and plasmid evolution. [PDF]
Nat Rev Microbiol, 2015 International audiencePolintons (also known as Mavericks) are large DNA transposons that are widespread in the genomes of eukaryotes. We have recently shown that Polintons encode virus capsid proteins, which suggests that these transposons might form ...

The Double-Stranded DNA Virosphere as a Modular Hierarchical Network of Gene Sharing [PDF]
mBio, 2016 Virus genomes are prone to extensive gene loss, gain, and exchange and share no universal genes. Therefore, in a broad-scale study of virus evolution, gene and genome network analyses can complement traditional phylogenetics.

New Brazilian giant viruses isolation from environmental samples using a panel of protozoa.
Frontiers in Microbiology, 2015 The Megavirales are a newly described order capable of infecting different types of eukaryotic hosts. For the most part, the natural host is unknown.

The Common Ancestor of Archaea and Eukarya Was Not an Archaeon [PDF]
Archaea, Volume 2013, Issue 1, 2013., 2013 It is often assumed that eukarya originated from archaea. This view has been recently supported by phylogenetic analyses in which eukarya are nested within archaea. Here, I argue that these analyses are not reliable, and I critically discuss archaeal ancestor scenarios, as well as fusion scenarios for the origin of eukaryotes.

Genomic comparison of closely related Giant Viruses supports an accordion-like model of evolution.
Frontiers in Microbiology, 2015 Genome gigantism occurs so far in Phycodnaviridae and Mimiviridae (order Megavirales). Origin and evolution of these Giant Viruses (GVs) remain open questions.

A Rapid Strategy for the Isolation of New Faustoviruses from Environmental Samples Using Vermamoeba vermiformis. [PDF]
J Vis Exp, 2016 International audienceThe isolation of giant viruses is of great interest in this new era of virology, especially since these giant viruses are related to protists. Giant viruses may be potentially pathogenic for many species of protists.
