A retrovirus is a type of virus that inserts a DNA copy of its RNA genome into the DNA of a host cell that it invades, thus changing the genome of that cell. [2] After invading a host cell's cytoplasm, the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backward).
Rarely, retroviral integration may occur in a germline cell that goes on to develop into a viable organism. This organism will carry the inserted retroviral genome as an integral part of its own genome—an "endogenous" retrovirus (ERV) that may be inherited by its offspring as a novel allele. Many ERVs have persisted in the genome of their ...
Simian foamy virus (SFV), historically Human foamy virus (HFV), is a species of the genus Spumavirus that belongs to the family of Retroviridae.It has been identified in a wide variety of primates, including prosimians, New World and Old World monkeys, as well as apes, and each species has been shown to harbor a unique (species-specific) strain of SFV, including African green monkeys, baboons ...

For example, some protect against infection with related viruses. [ 10 ] [ 11 ] In some mammal groups, including higher primates , retroviral envelope proteins have been exapted to produce a protein that is expressed in the placental syncytiotrophoblast , and is involved in fusion of the cytotrophoblast cells to form the syncytial layer of the ...
The gammaretroviruses can be spread horizontally, animal to animal, or vertically from parent to offspring. [15] Another gammaretrovirus reservoir was discovered in the genome of the bottlenose dolphin. This gammaretrovirus called Tursiops truncates endogenous retrovirus, was thought to be from extant mammalian endogenous gammaretroviruses.
The best example is represented by the case of CHV1 and C. parasitica. [14] Other examples of deleterious effects of mycoviruses are the ‘La France’ disease of A. bisporus [5] [38] and the mushroom diseases caused by Oyster mushroom spherical virus [39] and Oyster mushroom isometric virus. [38] In summary, the main negative effects of ...
Lentivirus is a genus of retroviruses that cause chronic and deadly diseases characterized by long incubation periods, in humans and other mammalian species. [2] The genus includes the human immunodeficiency virus (HIV), which causes AIDS.
