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.

Analysis of virus genomes from glacial environments reveals novel virus groups with unusual host interactions [PDF]
, 2015 Microbial communities in glacial ecosystems are diverse, active, and subjected to strong viral pressures and infection rates. In this study we analyse putative virus genomes assembled from three dsDNA viromes from cryoconite hole ecosystems of Svalbard ...

Amoebae, Giant Viruses, and Virophages Make Up a Complex, Multilayered Threesome
Frontiers in Cellular and Infection Microbiology, 2018 Viral infection had not been observed for amoebae, until the Acanthamoeba polyphaga mimivirus (APMV) was discovered in 2003. APMV belongs to the nucleocytoplasmatic large DNA virus (NCLDV) family and infects not only A.

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 ...

Quantitative Assessment of Nucleocytoplasmic Large DNA Virus and Host Interactions Predicted by Co-occurrence Analyses [PDF]
, 2021 Nucleocytoplasmic large DNA viruses (NCLDVs) are highly diverse and abundant in marine environments. However, the knowledge of their hosts is limited because only a few NCLDVs have been isolated so far.

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.

Evolution of exploitation and replication of giant viruses and virophages. [PDF]
Virus EvolAbstract Tripartite biotic interactions are inherently complex, and the strong interdependence of species and often one-sided exploitation can make these systems vulnerable to extinction. The persistence of species depends then on the balance between exploitation and avoidance of exploitation beyond the point where sustainable resource ...
