| lysogenic | 1. Causing or having the power to cause lysis, as the action of certain antibodies and chemical substances. 2. Pertaining to bacteria in the state of lysogeny. (05 Mar 2000) |

| lysogenic bacteria | <microbiology> A bacterium which contains in its genome the DNA of a virus which is lying dormant, passively letting itself be replicated by the bacterium whenever the bacterium replicates its own genome (a lysogenic virus), but able to reactivate and destroy the bacterium at a time of the virus's choosing (becomes a lytic virus). (15 Oct 1997) |
| lysogenic bacterium | A bacterium in the symbiotic condition in which its genome includes the genome (probacteriophage) of a temperate bacteriophage; in occasional instances the probacteriophage dissociates from the bacterial genome, develops into vegetative bacteriophage, and then matures, causing lysis of the respective host bacterium and release into the culture medium of infective temperate bacteriophage, formerly, a pseudolysogenic bacterial strain, i.e., a "carrier" strain of bacteriophage of low infectivity. (05 Mar 2000) |
| lysogenic conversion | <virology> The ability of some phages to survive in a bacterium as a result of the integration of their DNA into the host chromosome. The integrated DNA is termed a prophage. A regulator gene produces a repressor protein that suppresses the lytic activity of the phage, but various environmental factors, such as ultraviolet irradiation may prevent synthesis of the repressor, leading to normal phage development and lysis of the bacterium. The best example of this is bacteriophage lambda. (18 Nov 1997) |
| lysogenic induction | Induction that occurs when prophage is transferred to a nonlysogenic bacterium by conjugation or by transduction. (05 Mar 2000) |
| lysogenic infection | An infective process characterised by the incorporation of the DNA of the infecting phage into the host cell chromosome. Once incorporated, the phage DNA replicates along with the host DNA. The incorporated phage DNA is relatively inactive, thus permitting the host cell to continue fairly normal life processes. (14 Nov 1997) |
| lysogenic pathway | <virology> The method by which a virus becomes a dormant, passive part of its host bacterium's genome (a lysogenic virus), choosing to insert its DNA into the host's and postponing completion of its lytic cycle, at which time it destroys the host and spreads its progeny to infect other bacterial cells (enters the lytic pathway). (09 Oct 1997) |
| lysogenic strain | A strain of bacterium that is infected with a temporate bacteriophage. See: lysogeny. (05 Mar 2000) |
| lysogenic virus | <virology> A virus which has the capability to insert its DNA into the genome of the host bacterium for long-term dormancy, so that the bacterium replicates the viral DNA along with its own and passes it to its offspring. The virus is able to choose when it wants to reactivate and finish its lytic cycle, at which time it destroys the host and spreads its progeny to infect other bacterial cells. (09 Oct 1997) |
| lysogenicity | The property of being lysogenic. (05 Mar 2000) |

| lysogenic |
A type or phase of the virus life cycle during which the virus integrates into the host chromosome of the infected cell, remaining essentially dormant for some period of time. See lysogen.

|
| lysogenic |
A term describing a bacterium that contains a temperate phage in the prophage state. The bacterium is said to be lysogenic for that phage. On induction phage reproduction is initiated, progeny phages are produced, and the bacterial cell lyses.
