Origin of giant viruses from smaller DNA viruses not from a fourth domain of cellular life. [PDF]
Virology, 2014 The numerous and diverse eukaryotic viruses with large double-stranded DNA genomes that at least partially reproduce in the cytoplasm of infected cells apparently evolved from a single virus ancestor.

Marseilleviruses: An Update in 2021
Frontiers in Microbiology, 2021 The family Marseilleviridae was the second family of giant viruses that was described in 2013, after the family Mimiviridae. Marseillevirus marseillevirus, isolated in 2007 by coculture on Acanthamoeba polyphaga, is the prototype member of this family ...

Transboundary and Emerging Diseases, Volume 69, Issue 5, Page 2987-2995, September 2022., 2022 Abstract The emergence of high consequence animal diseases usually requires managing significant mortality. A desirable aspect of any carcass management method is the ability to contain and inactivate the target pathogen. The above‐ground burial (AGB) technique was recently developed and proposed as an alternative carcass management method.

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 ...

Frontiers in Microbiology, 2021 The family Asfarviridae is a group of nucleo-cytoplasmic large DNA viruses (NCLDVs) of which African swine fever virus (ASFV) is well-characterized. Recently the discovery of several Asfarviridae members other than ASFV has suggested that this family ...

Reclassification of Giant Viruses Composing a Fourth Domain of Life in the New Order <b><i>Megavirales</i></b> [PDF]
Intervirology, 2012 Interest in giant viruses has risen sharply since 2003, following the discovery of the Mimivirus and four other protist-infecting giant viruses that are linked to the nucleocytoplasmic large DNA viruses (NCLDVs). Despite considerable heterogeneity in hosts and genome sizes, the NCLDVs have been shown to be monophyletic based on analyses of their ...

Mimivirus Circulation among Wild and Domestic Mammals, Amazon Region, Brazil
Emerging Infectious Diseases, 2014 To investigate circulation of mimiviruses in the Amazon Region of Brazil, we surveyed 513 serum samples from domestic and wild mammals. Neutralizing antibodies were detected in 15 sample pools, and mimivirus DNA was detected in 9 pools of serum from ...

The Common Ancestor of Archaea and Eukarya Was Not an Archaeon
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.

Smaller Fleas: Viruses of Microorganisms
Scientifica, Volume 2012, Issue 1, 2012., 2012 Life forms can be roughly differentiated into those that are microscopic versus those that are not as well as those that are multicellular and those that, instead, are unicellular. Cellular organisms seem generally able to host viruses, and this propensity carries over to those that are both microscopic and less than truly multicellular.
