 VIRUSES: IMPORTED GENETIC SOFTWARE
In the lysogenic cycle the host cell does not make more viruses, but simply harbors the entire viral genome in the cell, usually by incorporating it into the cell's genome.
Sometimes after lysogenic integration of the viral genome into the host's DNA, an "induction event" can cause the viral infection to revert to the lytic cycle, in which the cell makes many copies of the virus and dies.
If the new infections are lysogenic, the virus's genes may again become integrated into the DNA of the new cells without harm to them.

During the lysogenic cyle an infected bacterium does not produce phage progeny nor release phage progeny into the extracellular environment.
A temperate phage is one that is capable of displaying a lysogenic infection.

 Gene Control
The lytic cycle occurs when the viral DNA immediately takes over the host cell (remember that viruses are obligate intracellular
Eventually the new viruses cause the rupture (or lysis) of the cell, releasing those new viruses to continue the infection cycle.
The lysogenic cycle occurs when the viral DNA is incorporated into the host DNA as a prophage.

Together with the plasma component complement, antibodies can kill bacteria directly.
It is important to note that antibodies cannot attack pathogens within cells, and certain viruses "hide" inside cells (as part of the lysogenic cycle) for long periods of time to avoid them.
This is the reason for the chronic nature of many minor skin diseases (such as cold sores); any given outbreak is quickly suppressed by the immune system, but the infection is never truly eradicated because some cells retain viruses that will resume the apparent symptoms later.

Recently scientists have learned that even during latency, some of the virus's genes can be expressed (11).
Lytic infection of one host followed by lysogenic infection in another is also called transduction.
