Variations of the Virome in Raw and Treated Water: A One‐Year Follow‐Up at Six Different Drinking Water Treatment Plants

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
This paper describes monitoring of outgoing water from drinking water treatment plants, geographically spread over half of Sweden and sampled every other month for 1 year. We found differences in the virome from the different water sources from each plant as well as differences in virus size and seasonal variation, where we also could detect viruses in

Viral metagenomics of Okavango Delta water pans reveal novel insights into wildlife disease potential

iMetaOmics, Volume 2, Issue 2, June 2025.
Botswana's Seronga region saw a mass elephant die‐off potentially linked to water sources. This study analyzes Okavango Delta metagenomes, uncovering a diversity of viruses and harmful pathogens. Findings highlight the importance of understanding viral ecology in these waters and support One Health's objective in protecting human, animal, and ecosystem

Discovery and Further Studies on Giant Viruses at the IHU Mediterranee Infection That Modified the Perception of the Virosphere

Viruses, 2019
The history of giant viruses began in 2003 with the identification of Acanthamoeba polyphaga mimivirus. Since then, giant viruses of amoeba enlightened an unknown part of the viral world, and every discovery and characterization of a new giant virus ...

Dinucleotide biases in the genomes of prokaryotic and eukaryotic dsDNA viruses and their hosts

Molecular Ecology, Volume 33, Issue 6, March 2024.
Abstract The genomes of cellular organisms display CpG and TpA dinucleotide composition biases. Such biases have been poorly investigated in dsDNA viruses. Here, we show that in dsDNA virus, bacterial, and eukaryotic genomes, the representation of TpA and CpG dinucleotides is strongly dependent on genomic G + C content.

Viral communities in millipede guts: Insights into the diversity and potential role in modulating the microbiome

Environmental Microbiology, Volume 26, Issue 2, February 2024.
Relative abundance of the metagenome‐assembled viral genomes (bottom arch) identified in the hindgut metagenomes and metatranscriptomes of Epibolus pulchripes and Glomeris connexa. The top arch shows the coverage of each viral phylum mapped to the identified metagenome‐assembled viral genomes in transcripts per million.

Phylogeny of the Varidnaviria Morphogenesis Module: Congruence and Incongruence With the Tree of Life and Viral Taxonomy

Frontiers in Microbiology, 2021
Double-stranded DNA viruses of the realm Varidnaviria (formerly PRD1-adenovirus lineage) are characterized by homologous major capsid proteins (MCPs) containing one (kingdom: Helvetiavirae) or two β-barrel domains (kingdom: Bamfordvirae) known as the ...

Guarani Virophage, a New Sputnik-Like Isolate From a Brazilian Lake

Frontiers in Microbiology, 2019
Virophages are critical regulators of viral population dynamics and potential actors in the stability of the microbial networks. These small biological entities predate the replicative cycle of giant viruses, such as the members of the Mimiviridae family

Giant viruses of amoebas: an update

Frontiers in Microbiology, 2016
During the 12 past years, five new or putative virus families encompassing several members, namely Mimiviridae, Marseilleviridae, pandoraviruses, faustoviruses, and virophages were described.

MG-Digger: an automated pipeline to search for giant virus-related sequences in metagenomes

Frontiers in Microbiology, 2016
The number of metagenomic studies conducted each year is growing dramatically. Storage and analysis of such big data is difficult and time-consuming. Interestingly, analysis shows that environmental and human metagenomes include a significant amount of ...
