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

Epigenetics and 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.

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,

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

Continuous year-round isolation of giant viruses from brackish shoreline soils [PDF]

Frontiers in Microbiology
Giant viruses, categorized under Nucleocytoviricota, are believed to exist ubiquitously in natural environments. However, comprehensive reports on isolated giant viruses remain scarce, with limited information available on unrecoverable strains, viral ...

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".

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

A Decade of Improvements in Mimiviridae and Marseilleviridae Isolation from Amoeba [PDF]

Intervirology, 2013
Since the isolation of the first giant virus, the Mimivirus, by T.J. Rowbotham in a cooling tower in Bradford, UK, and after its characterisation by our group in 2003, we have continued to develop novel strategies to isolate additional strains. By first focusing on cooling towers using our original time-consuming procedure, we were able to isolate a ...

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 ...

The genomic and phylogenetic analysis of <i>Marseillevirus cajuinensis</i> raises questions about the evolution of Marseilleviridae lineages and their taxonomical organization. [PDF]

J Virol
ABSTRACT Marseilleviruses (MsV) are a group of viruses that compose the Marseilleviridae family within the Nucleocytoviricota phylum. They have been found in different samples, mainly in freshwater. MsV are classically organized into five phylogenetic lineages (A/B/C/D/E), but the current taxonomy does
