Virophages—Known and Unknown Facts [PDF]
Viruses, 2023 The paper presents virophages, which, like their host, giant viruses, are “new” infectious agents whose role in nature, including mammalian health, is important. Virophages, along with their protozoan and algal hosts, are found in fresh inland waters and

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,

Virophage infection mode determines ecological and evolutionary changes in a host-virus-virophage system. [PDF]
ISME JGiant viruses can control their eukaryotic host populations, shaping the ecology and evolution of aquatic microbial communities. Understanding the impact of the viruses’ own parasites, the virophages, on the control of microbial communities remains a ...

Zamilon, a novel virophage with Mimiviridae host specificity. [PDF]
PLoS ONE, 2014 Virophages, which are potentially important ecological regulators, have been discovered in association with members of the order Megavirales. Sputnik virophages target the Mimiviridae, Mavirus was identified with the Cafeteria roenbergensis virus, and ...

Acanthamoeba polyphaga mimivirus Virophage Seroconversion in Travelers Returning from Laos
Emerging Infectious Diseases, 2012 During January 2010, a husband and wife returned from Laos to France with probable parasitic disease. Increased antibodies against an Acanthamoeba polyphaga mimivirus virophage indicated seroconversion. While in Laos, they had eaten raw fish, a potential

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

Isolation and Identification of a Large Green Alga Virus (Chlorella Virus XW01) of Mimiviridae and Its Virophage (Chlorella Virus Virophage SW01) by Using Unicellular Green Algal Cultures. [PDF]
J Virol, 2022 Parasitic virophages are small unicellular eukaryotic dsDNA viruses that rely on the viral factories of coinfecting giant/large dsDNA viruses for propagation.

Analysis of virus genomes from glacial environments reveals novel virus groups with unusual host interactions [PDF]
Frontiers in Microbiology, 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 ...

A virophage cross-species infection through mutant selection represses giant virus propagation, promoting host cell survival. [PDF]
Commun Biol, 2020 Virus adaptation to new hosts is a major cause of infectious disease emergence. This mechanism has been intensively studied in the context of zoonotic virus spillover, due to its impact on global health.
