Viral metagenomics of Okavango Delta water pans reveal novel insights into wildlife disease potential. [PDF]

IMetaOmics
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

Disentangling the origins of virophages and polintons [PDF]

Current Opinion in Virology, 2017
Virophages and polintons are part of a complex system that also involves eukaryotes, giant viruses, as well as other viruses and transposable elements. Virophages are cosmopolitan, being found in environments ranging from the Amazon River to Antarctic hypersaline lakes, while polintons are found in many single celled and multicellular eukaryotes ...

Polar Microalgae: New Approaches towards Understanding Adaptations to an Extreme and Changing Environment [PDF]

, 2014
Polar Regions are unique and highly prolific ecosystems characterized by extreme environmental gradients. Photosynthetic autotrophs, the base of the food web, have had to adapt physiological mechanisms to maintain growth, reproduction and metabolic ...

Role of the R349 Gene and Its Repeats in the MIMIVIRE Defense System

Frontiers in Microbiology, 2019
MIMIVIRE is a defense system described in lineage A Mimivirus (Mimiviridae family) that mediates resistance against Zamilon virophage. It is composed of putative helicase and nuclease associated with a gene of unknown function called R349, which contains

Characterisation of host growth after infection with a broad-range freshwater cyanopodophage [PDF]

, 2014
Freshwater cyanophages are poorly characterised in comparison to their marine counterparts, however, the level of genetic diversity that exists in freshwater cyanophage communities is likely to exceed that found in marine environments, due to the habitat

A new Zamilon-like virophage partial genome assembled from a bioreactor metagenome

Frontiers in Microbiology, 2015
Virophages replicate within viral factories inside the Acanthamoeba cytoplasm, and decrease the infectivity and replication of their associated giant viruses.

A classification system for virophages and satellite viruses [PDF]

Archives of Virology, 2015
Satellite viruses encode structural proteins required for the formation of infectious particles but depend on helper viruses for completing their replication cycles. Because of this unique property, satellite viruses that infect plants, arthropods, or mammals, as well as the more recently discovered satellite-like viruses that infect protists ...

Broad spectrum of mimiviridae virophage allows its isolation using a mimivirus reporter. [PDF]

PLoS ONE, 2013
The giant virus Mimiviridae family includes 3 groups of viruses: group A (includes Acanthamoeba polyphaga Mimivirus), group B (includes Moumouvirus) and group C (includes Megavirus chilensis).

Identification of Capsid/Coat Related Protein Folds and Their Utility for Virus Classification [PDF]

, 2017
The viral supergroup includes the entire collection of known and unknown viruses that roam our planet and infect life forms. The supergroup is remarkably diverse both in its genetics and morphology and has historically remained difficult to study and ...

Viruses, virophages, and their living nature

Acta Virologica, 2010
Over 100 years viruses have fascinated scientists around the world. Although biologists, chemists, physicians, veterinarians, and even physicists attempted to elucidate the nature of viruses, the question still remains "Are viruses alive?" Different theories have aimed at unifying our views of virology to provide an answer.
