Experimental Inoculation in Rats and Mice by the Giant Marseillevirus Leads to Long-Term Detection of Virus [PDF]

Frontiers in Microbiology, 2018
The presence of the giant virus of amoeba Marseillevirus has been identified at many different sites on the human body, including in the bloodstream of asymptomatic subjects, in the lymph nodes of a child with adenitis, in one adult with Hodgkin's ...

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
International audienceABSTRACT 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.

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

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 ...

Megaviruses contain various genes encoding for eukaryotic vesicle trafficking factors

Traffic, Volume 23, Issue 8, Page 414-425, August 2022., 2022
Giant viruses enter their eukaryotic host cells by phagocytosis. For reproduction, they hijack the host cell's membranes by an unknown mechanism. Here, we found that giant viruses express several core factors of the eukaryotic vesicle fusion machinery, including SNARE, Rab, SM proteins, and the disassembly protein NSF.

First Isolation of a Marseillevirus in the Diptera Syrphidae Eristalis tenax [PDF]

Intervirology, 2013
<b><i>Objective:</i></b> Giant viruses and amoebae are common in freshwater, where they can coexist with various insects. We screened insect larvae to detect giant viruses using a high-throughput method. <b><i>Methods:</i></b> We analyzed 86 <i>Eristalis tenax</i> larvae obtained from stagnant

Diversity of Amoeba-Associated Giant Viruses Isolated in Algeria

Diversity, 2020
The discovery of several giant amoeba viruses has opened up a novel area in the field of virology. Despite this, knowledge about ecology of these viruses remains patchy. In this study, we aimed to characterize the diversity of giant viruses in Algeria by

Marseillevirus G648 ORFs

, 2022
A giant virus genome is densely packaged by stable nucleosomes within virions.The two doublet histones of Marseillevirus are distantly related to the four eukaryotic core histones and wrap 121 basepairs of DNA to form remarkably similar nucleosomes.
