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 ...

Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

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).

Transcriptomic evidence of a fourth mininucleovirus (Mininucleoviridae): A rapidly growing family among the Nucleo-Cytoplasmic Large DNA viruses (NCLDVs)

Journal of Invertebrate Pathology
The Mininucleoviridae are crustacean-infecting viruses thought to drive mortality across aquatic biomes. Three have been characterised from Carcinus maenas, Panulirus argus, and Dikerogammarus haemobaphes. We screened 202 SRA datasets (NCBI) for novel mininucleoviruses from 44 amphipod species.

Detection of African Swine Fever Virus (ASFV) in Haematopinus suis: Evidence for a Potential New Sylvatic Cycle of ASFV Involving Lice and Domestic Pigs

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
African swine fever (ASF) is a lethal and highly contagious viral disease of domestic and wild pigs, listed as a notifiable disease to the World Organization for Animal Health (WOAH). In the absence of any credible commercially available vaccine, the economic losses to the global pig industry inflicted by ASF is insurmountable.

The Viral Fraction Metatranscriptomes of Lake Baikal

Microorganisms, 2022
This article characterises viral fraction metatranscriptomes (smaller than 0.2 µm) from the pelagic zone of oligotrophic Lake Baikal (Russia). The study revealed the dominance of transcripts of DNA viruses: bacteriophages and algal viruses. We identified

Poxvirus Host Range Genes and Virus–Host Spectrum: A Critical Review

Viruses, 2017
The Poxviridae family is comprised of double-stranded DNA viruses belonging to nucleocytoplasmic large DNA viruses (NCLDV). Among the NCLDV, poxviruses exhibit the widest known host range, which is likely observed because this viral family has been more ...
