(A) When the host cell is only infected by a giant virus, the latter establishes a cytoplasmic virus factory to replicate and generates new virions, and the host cell is most likely lysed at the end of its replication cycle. (B) When the host cell is co-infected with a giant virus and its virophage, the latter parasitizes the giant virus factory.

Vaccines are another method of virotherapy that use attenuated or inactivated viruses to develop immunity to disease. An attenuated virus is a weakened virus that incites a natural immune response in the host that is often undetectable. The host also develops potentially life-long immunity due to the attenuated virus's similarity to the actual ...
Zamilon was discovered in 2013, in Acanthamoeba polyphaga amoebae co-infected with the giant virus Mont1, isolated from a Tunisian soil sample. [2] [3] [5] As of 2015, Zamilon is one of three virophages to have been isolated physically, the others being Sputnik and Mavirus; several other virophage DNAs have been discovered using metagenomics but have not been characterised physically.
Human betaretrovirus (HBRV), also known as Human mammary tumor virus, or Mouse mammary tumor-like virus is the human homologue of the Mouse mammary tumor virus (MMTV). The nomenclature for Human betaretrovirus was introduced following characterization of infection in patient with autoimmune liver disease suggesting the virus is not solely found in mice nor exclusively implicated in the ...
Viruses like Sputnik that depend on co-infection of the host cell by helper viruses are known as satellite viruses. At its discovery in a Paris water-cooling tower in 2008, Sputnik was the first known satellite virus that inhibited replication of its helper virus and thus acted as a parasite of that virus. In analogy, it was called a virophage. [2]
Virophages are satellite viruses that inhibit or impair the reproduction of the auxiliary virus. Pages in category "Virophages" The following 7 pages are in this category, out of 7 total.
ECHO-7 (trade name Rigvir) is a wild type member of the echovirus group of viruses. [1] It was formerly approved as a virotherapy medication by the State Agency of Medicines of the Republic of Latvia (2004–19). [2]
