lysogen

The host can be termed a lysogen when a prophage is present.

The reason is that the lysogen is continuously producing cI repressor.

He created the classic induction of a lysogen involved irradiating the infected cells with ultraviolet light.

Alternatively, lysogen can refer to a strain of bacterium that carries a prophage.

However, recent experiments suggest that physical differences among cells, that exist prior to infection, predetermine whether a cell will lyse or become a lysogen.

When a cell is a lambda lysogen, another lambda phage that infects is not able to undergo lytic development and produce phage.

Any situation where a lysogen undergoes DNA damage or the SOS response of the host is otherwise stimulated leads to induction.

A lysogen or lysogenic phage is a phage that can exist as a DNA in its dormant state (prophage) within its host organism.

Many (but not all) temperate phages can integrate their genomes into their host bacterium's chromosome, together becoming a lysogen as the phage genome becomes a prophage.

The relatively large size of the plasmid requires it to keep a low copy number lest it become too large a metabolic burden while it is a lysogen.

Virulence genes carried within prophages as discrete autonomous genetic elements, known as morons, confer an advantage to the bacteria that indirectly benefits the virus through enhanced lysogen survival.

If the lysogen is induced (by UV light for example), the phage genome is excised from the bacterial chromosome and initiates the lytic cycle, which culminates in lysis of the cell and the release of phage particles.
