Coral Bleaching Phenotypes Associated With Differential Abundances of Nucleocytoplasmic Large DNA Viruses

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

Epidermal multinucleated giant cells are not always a histopathologic clue to a herpes virus infection: multinucleated epithelial giant cells in the epidermis of lesional skin biopsies from patients with acantholytic dermatoses can histologically mimic a

Dermatology Practical & Conceptual, 2014
Background: Multinucleated giant cells in the epidermis can either be epithelial or histiocytic. Epithelial multinucleated giant cells are most often associated with herpes virus infections.

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 ...

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 ...

Naiavirus: an enveloped giant virus with a pleomorphic, flexible tail. [PDF]

Nat Commun
Numerous studies have shown that viruses are present in a variety of environments on Earth, acting as drivers of biogeochemical cycles and powerful selective forces. Among them, giant viruses of amoebae have garnered attention from the scientific community due to their large particles and extensive genomes. Here, we describe the discovery of one of the

Cryptic infection of a giant virus in a unicellular green alga. [PDF]

Science
Latency is a common strategy in a wide range of viral lineages, but its prevalence in giant viruses remains unknown. In this work, we describe a 617–kilo–base pairs integrated giant viral element in the model green alga Chlamydomonas reinhardtii .

Structural and Proteomic Studies of the Aureococcus anophagefferens Virus Demonstrate a Global Distribution of Virus-Encoded Carbohydrate Processing

Frontiers in Microbiology, 2020
Viruses modulate the function(s) of environmentally relevant microbial populations, yet considerations of the metabolic capabilities of individual virus particles themselves are rare. We used shotgun proteomics to quantitatively identify 43 virus-encoded

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

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 ...
