Giant variations in giant virus genome packaging
Trends in Biochemical Sciences, 2023 Giant viruses (Nucleocytoviricota) have a largely conserved lifecycle, yet how they cram their large genomes into viral capsids is mostly unknown. The major capsid protein and the packaging ATPase (pATPase) comprise a highly conserved morphogenesis module in giant viruses, yet some giant viruses dispense with an icosahedral capsid, and others encode ...

Varicella zoster virus and giant cell arteritis [PDF]
Current Opinion in Infectious Diseases, 2016 Giant cell arteritis (GCA) is a serious disease and the most common cause of vasculitis in the elderly. Here, studies describing the recent discovery of varicella zoster virus (VZV) in the temporal arteries of patients with GCA are reviewed.GCA is characterized by severe headache/head pain and scalp tenderness.

A giant virus infecting the amoeboflagellate Naegleria. [PDF]
Nat CommunAbstractGiant viruses (Nucleocytoviricota) are significant lethality agents of various eukaryotic hosts. Although metagenomics indicates their ubiquitous distribution, available giant virus isolates are restricted to a very small number of protist and algal hosts.

Near-atomic structure of a giant virus. [PDF]
Nat Commun, 2019 Abstract Although the nucleocytoplasmic large DNA viruses (NCLDVs) are one of the largest group of viruses that infect many eukaryotic hosts, the near-atomic resolution structures of these viruses have remained unknown. Here we describe a 3.5 Å resolution icosahedrally averaged capsid structure of Paramecium bursaria chlorella virus 1

A Brief History of Giant Viruses’ Studies in Brazilian Biomes
Viruses, 2022 Almost two decades after the isolation of the first amoebal giant viruses, indubitably the discovery of these entities has deeply affected the current scientific knowledge on the virosphere. Much has been uncovered since then: viruses can now acknowledge

Evolutionary Dynamics of Giant Viruses and their Virophages [PDF]
, 2013 Giant viruses contain large genomes, encode many proteins atypical for viruses, replicate in large viral factories, and tend to infect protists. The giant virus replication factories can in turn be infected by so called virophages, which are smaller ...

Quantitative Infection Dynamics of Cafeteria Roenbergensis Virus
Viruses, 2018 The discovery of giant viruses in unicellular eukaryotic hosts has raised new questions on the nature of viral life. Although many steps in the infection cycle of giant viruses have been identified, the quantitative life history traits associated with ...

Frontiers in Marine Science, 2020 Eukaryotic viruses and bacteriophage have been implicated in disease and bleaching in corals, but the compositional and functional diversity of these viruses in healthy and compromised hosts remains underexplored. To investigate whether viral assemblages

Past and present giant viruses diversity explored through permafrost metagenomics
Nature Communications, 2022 Although giant viruses are abundant in aquatic environments, less is known about giant viruses in soil. Here, the authors use permafrost metagenomics to reveal giant virus diversity and heterogeneity, as well as gene transfers between viruses from ...

An Update on Eukaryotic Viruses Revived from Ancient Permafrost
Viruses, 2023 One quarter of the Northern hemisphere is underlain by permanently frozen ground, referred to as permafrost. Due to climate warming, irreversibly thawing permafrost is releasing organic matter frozen for up to a million years, most of which decomposes ...
