Virophages, Satellite Viruses, Virophage Replication and Its Effects and Virophage Defence Mechanisms for Giant Virus Hosts and Giant Virus Defence Systems against Virophages. [PDF]
Int J Mol SciIn this paper, the characteristics of 40 so far described virophages—parasites of giant viruses—are given, and the similarities and differences between virophages and satellite viruses, which also, like virophages, require helper viruses for replication,

Virophages of Giant Viruses: An Update at Eleven [PDF]
Viruses, 2019 The last decade has been marked by two eminent discoveries that have changed our perception of the virology field: The discovery of giant viruses and a distinct new class of viral agents that parasitize their viral factories, the virophages.

Novel virophages discovered in a freshwater lake in China [PDF]
Frontiers in Microbiology, 2016 Virophages are small double-stranded DNA viruses that are parasites of giant DNA viruses that infect unicellular eukaryotes. Here we identify a novel group of virophages, named Dishui Lake virophages (DSLVs) that were discovered in Dishui Lake (DSL): an ...

Simultaneous Giant Virus and Virophage Quantification Using Droplet Digital PCR [PDF]
Viruses, 2022 Viruses are an abundant component of aquatic systems, but their detection and quantification remain a challenge. Virophages co-replicate with giant viruses in the shared host cell, and can inhibit the production of new giant virus particles, thereby ...

Evolution of exploitation and replication of giant viruses and virophages. [PDF]
Virus EvolTripartite 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

Virophages and Their Interactions with Giant Viruses and Host Cells [PDF]
Proteomes, 2018 Virophages are small dsDNA viruses that were first isolated in association with some giant viruses (GVs), and then found in metagenomics samples. They encode about 20–34 proteins.

Diversity, evolution, and classification of virophages uncovered through global metagenomics [PDF]
Microbiome, 2019 Background Virophages are small viruses with double-stranded DNA genomes that replicate along with giant viruses and co-infect eukaryotic cells. Due to the paucity of virophage reference genomes, a collective understanding of the global virophage ...

Guarani Virophage, a New Sputnik-Like Isolate From a Brazilian Lake [PDF]
Frontiers in Microbiology, 2019 Virophages are critical regulators of viral population dynamics and potential actors in the stability of the microbial networks. These small biological entities predate the replicative cycle of giant viruses, such as the members of the Mimiviridae family

Endogenous virophages are active and mitigate giant virus infection in the marine protist Cafeteria burkhardae. [PDF]
Proc Natl Acad Sci U S ASignificance Single-celled eukaryotes are parasitized by viruses just like other life forms, but compared to bacteria or animals, their defense systems against viral infection remain unknown.
