provirus

 [pro-vi´rus]
a DNA transcript of an RNA virus that migrates from the cytoplasm into the nucleus and integrates into the host genome by crossing over so that it will be thus replicated in the daughter cells.

pro·vi·rus

(prō-vī'rŭs),
The precursor of an animal virus, usually a retrovirus; theoretically analogous to the prophage in bacteria, the provirus is integrated in the nucleus of infected cells and can be activated in response to certain stimuli.

provirus

/pro·vi·rus/ (pro-vi´rus) the genome of an animal virus integrated (by crossing over) into the chromosome of the host cell, and thus replicated in all of its daughter cells. It can be activated to produce a complete virus; it can also cause transformation of the host cell.

provirus

(prō′vī′rəs, prō-vī′-)
n. pl. provi·ruses
A form of a virus that allows it to be integrated into the genome of a host cell and to replicate in concert with the cell's genetic material without causing cell lysis.

pro′vi′ral (-rəl) adj.

provirus

[-vī′rəs]
a stage of viral replication in which the viral genetic information has been integrated into the genome of the host cell. It may be activated spontaneously or by a specific stimulus to direct the cell to produce new virions to progress to a complete virus.

pro·vi·rus

(prō-vī'rŭs)
The precursor of an animal virus; theoretically analogous to the prophage in bacteria, the provirus being integrated into the nucleus of infected cells.

provirus

the DNA of a VIRUS that has integrated into the DNA of the host CELL and is transmitted from one cell generation to the next in this state. No infective virus particles are produced. The provirus can excise from the host's DNA and resume a productive viral cycle with the production of virus particles.

pro·vi·rus

(prō-vī'rŭs)
The precursor of an animal virus; theoretically analogous to the prophage in bacteria, the provirus being integrated into the nucleus of infected cells.

provirus (prōvī´rus),

n a type of virus incorporated into a host cell's genetic material that transmits from one generation of cells to the next via cell replication without triggering the separation or decomposition of the cell.

provirus

the genome of an animal virus integrated into the chromosome of the host cell, and thus transferred to in all of its daughter cells.

That approach refers to forcing dormant proviruses to "turn back on," making them "visible" and vulnerable to the immune system's cytolytic "killer" T cells, and then eliminating every last infected cell from the body while antiretroviral drugs prevent any new cells from becoming infected.
EAV are also present in line-0 chickens (ev-negative), which have been bred to have no ev proviruses (12).
If germ cells are infected, proviruses become part of the genetic dowry of the host species, inherited as classical Mendelian genes and evolving in concert with the host genome.
