A Brazilian Marseillevirus Is the Founding Member of a Lineage in Family Marseilleviridae [PDF]

Viruses, 2016
In 2003, Acanthamoeba polyphaga mimivirus (APMV) was discovered as parasitizing Acanthamoeba. It was revealed to exhibit remarkable features, especially odd genomic characteristics, and founded viral family Mimiviridae.

Mimiviridae, Marseilleviridae, and virophages as emerging human pathogens causing healthcare-associated infections

GMS Hygiene and Infection Control, 2014
[english] Aim: During the last decade it became obvious that viruses belonging to and families (order Megavirales), may be potential causative agents of pneumonia. Thus, we have performed a review of the association of , , and virophages with pneumonia,

Virome characterization and identification of a putative parvovirus and poxvirus in bat ectoparasites of Yunnan Province, China [PDF]

One Health, 2023
Ectoparasites found on bats are known to contain important microbes. However, the viruses hosted by these obligate parasites are understudied. This has led to the near oversight of the potential role of these ectoparasites in virus maintenance and ...

Viral ecogenomics across the Porifera [PDF]

Microbiome, 2020
BackgroundViruses directly affect the most important biological processes in the ocean via their regulation of prokaryotic and eukaryotic populations. Marine sponges form stable symbiotic partnerships with a wide diversity of microorganisms and this high

Phylogenetic analysis of the core histone doublet and DNA topo II genes of Marseilleviridae: evidence of proto-eukaryotic provenance [PDF]

Epigenetics & Chromatin, 2017
Background While the genomes of eukaryotes and Archaea both encode the histone-fold domain, only eukaryotes encode the core histone paralogs H2A, H2B, H3, and H4.

Marseilleviridae Lineage B Diversity and Bunch Formation Inhibited by Galactose. [PDF]

Microbes Environ, 2021
Marseilleviridae is a family of large double-stranded DNA viruses that is currently divided into five subgroups, lineages A-E. Hokutovirus and kashiwazakivirus, both of which belong to lineage B, have been reported to induce host acanthamoeba cells to form aggregations called "bunches".

Presence of CRISPR CAS-Like Sequences as a Proposed Mechanism for Horizontal Genetic Exchanges between Trichomonas vaginalis and Its Associated Virus: A Comparative Genomic Analysis with the First Report of a Putative CRISPR CAS Structures in Eukaryotic Cells. [PDF]

Biomed Res Int, 2023
Introduction. Trichomonas vaginalis genome is among the largest genome size and coding capacities. Combinations of gene duplications, transposon, repeated sequences, and lateral gene transfers (LGTs) have contributed to the unexpected large genomic size and diversity. This study is aimed at investigating genomic exchange and seeking for presence of the

Comparative glycomic analysis of Mimiviridae and Marseilleviridae uncovers host-related and lineage-specific glycosylation. [PDF]

J Biochem
Abstract Giant viruses encode unusual glycosylation machinery distinct from their amoebal hosts, raising fundamental questions about how their glycans are synthesized and diversified. Here we present a comparative glycomic analysis of mimivirus, tokyovirus, and hokutovirus, together with their common host Acanthamoeba castellanii. The

“Marseilleviridae”, a new family of giant viruses infecting amoebae [PDF]

Archives of Virology, 2012
The family "Marseilleviridae" is a new proposed taxon for giant viruses that infect amoebae. Its first member, Acanthamoeba polyphaga marseillevirus (APMaV), was isolated in 2007 by culturing on amoebae a water sample collected from a cooling tower in Paris, France. APMaV has an icosahedral shape with a diameter of ≈250 nm.

A rapid genome‐wide analysis of isolated giant viruses using MinION sequencing

Environmental Microbiology, Volume 25, Issue 11, Page 2621-2635, November 2023., 2023
We evaluated performance of MinION sequencing for giant virus genomics. Re‐sequencing of a prototype marseillevirus by MinION alone provided high‐quality genomes. As a proof of concept, we sequenced genomes of newly isolated giant viruses. Collectively, we concluded that MinION sequencing is an effective approach to rapidly perform a genome‐wide ...
