Analysis of a Marseillevirus Transcriptome Reveals Temporal Gene Expression Profile and Host Transcriptional Shift

Frontiers in Microbiology, 2020
Marseilleviruses comprise a family of large double-stranded DNA viruses belonging to the proposed order “Megavirales.” These viruses have a circular genome of ∼370 kbp, coding hundreds of genes.

A Rapid Strategy for the Isolation of New Faustoviruses from Environmental Samples Using Vermamoeba vermiformis. [PDF]

J Vis Exp, 2016
International audienceThe isolation of giant viruses is of great interest in this new era of virology, especially since these giant viruses are related to protists. Giant viruses may be potentially pathogenic for many species of protists.

Samba virus: a novel mimivirus from a giant rain forest, the Brazilian Amazon [PDF]

, 2014
International audienceBackgroundThe identification of novel giant viruses from the nucleocytoplasmic large DNA viruses group and their virophages has increased in the last decade and has helped to shed light on viral evolution.

Identification of giant Mimivirus protein functions using RNA interference

Frontiers in Microbiology, 2015
Genomic analysis of giant viruses, such as Mimivirus, has revealed that more than half of the putative genes have no known functions (ORFans). We knocked down Mimivirus genes using short interfering RNA (siRNA) as a proof of concept to determine the ...

Supplementary Material for: Reclassification of Giant Viruses Composing a Fourth Domain of Life in the New Order Megavirales

, 2017
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).

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

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 ...

Cytochromes b5 Occurrence in Viruses Belonging to the Order Megavirales

Abstract Cytochrome b5 is a small electron transport protein that is found in animals, plants, fungi and photosynthetic proteobacteria where it plays key metabolic roles in energy production, lipid and sterol biosynthesis and cytochrome P450 biochemistry.

Pan-Genome Analysis of Brazilian Lineage A Amoebal Mimiviruses

Viruses, 2015
Since the recent discovery of Samba virus, the first representative of the family Mimiviridae from Brazil, prospecting for mimiviruses has been conducted in different environmental conditions in Brazil. Recently, we isolated using Acanthamoeba sp.
