Microscopic Characterization of the Brazilian Giant Samba Virus

Viruses, 2017
Prior to the discovery of the mimivirus in 2003, viruses were thought to be physically small and genetically simple. Mimivirus, with its ~750-nm particle size and its ~1.2-Mbp genome, shattered these notions and changed what it meant to be a virus. Since

Virus viability in spiked swine bone marrow tissue during above‐ground burial method and under in vitro conditions

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.

Comparative Genomics and Environmental Distribution of Large dsDNA Viruses in the Family Asfarviridae

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 ...

The analysis of translation-related gene set boosts debates around origin and evolution of mimiviruses. [PDF]

PLoS Genetics, 2017
The giant mimiviruses challenged the well-established concept of viruses, blurring the roots of the tree of life, mainly due to their genetic content.

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.

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 ...

Acanthamoeba polyphaga mimivirus stability in environmental and clinical substrates: implications for virus detection and isolation. [PDF]

PLoS ONE, 2014
Viruses are extremely diverse and abundant and are present in countless environments. Giant viruses of the Megavirales order have emerged as a fascinating research topic for virologists around the world.
