Updated Virophage Taxonomy and Distinction from Polinton-like Viruses [PDF]
Biomolecules, 2023 Virophages are small dsDNA viruses that hijack the machinery of giant viruses during the co-infection of a protist (i.e., microeukaryotic) host and represent an exceptional case of “hyperparasitism” in the viral world.

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 ...

Conserved tripartite tail proteins mediate virophage-host interactions through Synechococcus lipopolysaccharide binding [PDF]
Journal of VirologyVirophages are small double-stranded DNA viruses that parasitize giant viruses and play crucial roles in microbial ecosystem dynamics. In this study, we investigate three evolutionarily conserved tail proteins in Dishui Lake Virophage 2 (DSLV2) that ...

The Discovery of a New Mimivirus Isolate in Association with Virophage-Transpoviron Elements in Brazil Highlights the Main Genomic and Evolutionary Features of This Tripartite System [PDF]
Viruses, 2022 Mimiviruses are giant viruses of amoeba that can be found in association with virophages. These satellite-like viruses are dependent on the mimivirus viral factory to replicate.

Diversity, Relationship, and Distribution of Virophages and Large Algal Viruses in Global Ocean Viromes [PDF]
Viruses, 2023 Virophages are a group of small double-stranded DNA viruses that replicate and proliferate with the help of the viral factory of large host viruses. They are widely distributed in aquatic environments but are more abundant in freshwater ecosystems. Here,

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

Pantanal virophage: a new virophage species associated with a moumouvirus and a transpoviron, expanding the genus Sputnikvirus [PDF]
Journal of VirologyAmoeba-infecting giant viruses, such as mimiviruses, challenged paradigms of virology since their discovery. Their extensive and complex genomes and particle structures can interact with virophages and transpovirons, revealing unique aspects of the viral
