Lateral Gene Transfer Between Protozoa-Related Giant Viruses of Family Mimiviridae and Chlamydiae [PDF]

Evolutionary Bioinformatics, 2018
Obligate intracellular chlamydiae diverged into pathogenic and environmental chlamydiae 0.7-1.4 billion years ago. While pathogenic chlamydiae have adapted to a wide range of vertebrates, environmental chlamydiae inhabit unicellular amoebae, the free ...

Mimiviridae: clusters of orthologous genes, reconstruction of gene repertoire evolution and proposed expansion of the giant virus family

Virology Journal, 2013
The family Mimiviridae belongs to the large monophyletic group of Nucleo-Cytoplasmic Large DNA Viruses (NCLDV; proposed order Megavirales) and encompasses giant viruses infecting amoeba and probably other unicellular eukaryotes.

Mimiviridae: A Rising Family of Highly Diverse Large Aquatic dsDNA Viruses Infecting a Wide Variety of Eukaryotes [PDF]

, 2018
Since 1998, when Jim van Etten’s team initiated its characterization, Paramecium bursaria Chlorella virus 1 (PBCV-1) had been the largest known DNA virus, both in terms particle size and genome complexity.

Metagenomic detection of Mimiviridae reads in upper respiratory tract samples of SARS-CoV-2 patients

medRxiv
The upper respiratory tract (URT) virome is crucial in respiratory health and response to pathogens. While common respiratory viruses are well-studied, the presence and potential impact of giant DNA viruses, such as Mimiviridae, in the human URT remain ...

Presence of Protozoan Viruses in Vaginal Samples from Pregnant Women and Their Association with Trichomoniasis. [PDF]

Pathogens
This study was conducted in Armenia and included 32 pregnant women with TV infection and 30 healthy controls. The vaginal virome includes viruses that infect human cells and unicellular eukaryotes such as Trichomonas vaginalis (TV).

Viral Diversity of Coastal Restinga Soils From Southern Brazil. [PDF]

Environ Microbiol Rep
Coastal ecotones are highly dynamic environments for viral studies due to their extreme abiotic conditions, transitional nature between marine and terrestrial domains and high biodiversity. In Brazil, the Restinga is a coastal ecotone along the shoreline,

“Tupanvirus”, a new genus in the family Mimiviridae [PDF]

Archives of Virology, 2018
The genus "Tupanvirus" is a new proposed taxon to be included in the family Mimiviridae. The two known tupanvirus isolates were isolated from soda lake and oceanic sediments samples collected in Brazil and were named "tupanvirus soda lake" and "tupanvirus deep ocean", respectively. These viruses exhibit similarities to amoeba-infecting mimiviruses, but

Transition metals and oxidation reactions trigger stargate opening during the initial stages of the replicative cycle of the giant Tupanvirus

mBio
Tupanviruses, members of the family Mimiviridae, infect phagocytic cells. Particle uncoating begins inside the phagosome, with capsid opening via the stargate. The mechanism through which this opening takes place is unknown.
