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

Marseilleviruses: An Update in 2021

Frontiers in Microbiology, 2021
The family Marseilleviridae was the second family of giant viruses that was described in 2013, after the family Mimiviridae. Marseillevirus marseillevirus, isolated in 2007 by coculture on Acanthamoeba polyphaga, is the prototype member of this family ...

Morphological and Genomic Features of the New Klosneuvirinae Isolate Fadolivirus IHUMI-VV54

Frontiers in Microbiology, 2021
Since the discovery of Mimivirus, viruses with large genomes encoding components of the translation machinery and other cellular processes have been described as belonging to the nucleocytoplasmic large DNA viruses. Recently, genome-resolved metagenomics

Development of eNA Sampling for Early Detection of Pathogens in On‐Farm Water Sources

Environmental DNA, Volume 8, Issue 2, March/April 2026.
We compare four water‐sampling methods for detecting microbial and viral eNA in livestock troughs and show all approaches effectively recover community profiles, supporting flexible, field‐ready surveillance of livestock pathogens. ABSTRACT Early detection of livestock pathogens is critical for mitigating risk and implementing timely control or ...

Insights Into Sequences of Viral and Bacterial Origin in the Metatranscriptome of Centaurea cyanus L. Susceptible and Resistant to Acetolactate Synthase (ALS)‐Inhibiting Herbicides

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Metatranscriptomic analysis of Centaurea cyanus revealed diverse plant‐associated viral and bacterial sequences in herbicide‐susceptible and ‐resistant biotypes. While novel partitiviruses occurred independently of resistance status, differences in bacterial community composition may suggest a potential role of the plant microbiome in responses to ...

A Student’s Guide to Giant Viruses Infecting Small Eukaryotes: From Acanthamoeba to Zooxanthellae

Viruses, 2017
The discovery of infectious particles that challenge conventional thoughts concerning “what is a virus” has led to the evolution a new field of study in the past decade.

Phylogenetic and phyletic studies of informational genes in genomes highlight existence of a 4 domain of life including giant viruses. [PDF]

PLoS ONE, 2010
The discovery of Mimivirus, with its very large genome content, made it possible to identify genes common to the three domains of life (Eukarya, Bacteria and Archaea) and to generate controversial phylogenomic trees congruent with that of ribosomal genes,

Diversity and Ecological Potentials of Marine Viruses Inhabiting Continental Shelf Seas

Advanced Science, Volume 13, Issue 1, 5 January 2026.
To the best of the knowledge, this study provides the largest viral genome dataset from a continental shelf sea. It reveals that over half of vOTUs are novel, highlighting the remarkable viral novelty in the eastern continental shelf seas of China (ECSSC).

Hidden diversity of soil giant viruses

Nature Communications, 2018
Current knowledge of giant virus diversity is largely based on samples from aquatic environments. Here the authors employ cultivation-independent metagenomics and mini-metagenomics on forest soil and identify 16 novel giant virus genomes, some of which ...

Virus Genomes from Deep Sea Sediments Expand the Ocean Megavirome and Support Independent Origins of Viral Gigantism

mBio, 2019
The nucleocytoplasmic large DNA viruses (NCLDV) of eukaryotes (proposed order, “Megavirales”) include the families Poxviridae, Asfarviridae, Iridoviridae, Ascoviridae, Phycodnaviridae, Marseilleviridae, and Mimiviridae, as well as still unclassified ...
