Lysogens can remain in the lysogenic cycle for many generations but can switch to the lytic cycle at any time via a process known as induction. [8] During induction, prophage DNA is excised from the bacterial genome and is transcribed and translated to make coat proteins for the virus and regulate lytic growth. [8] Lysogenic Cycle [9]
A lysogen or lysogenic bacteria is a bacterial cell that can produce and transfer the ability to produce a phage. [1] A prophage is either integrated into the host bacteria 's chromosome or more rarely exists as a stable plasmid within the host cell.
The lytic pathway causes the host to produce and release progeny virions, usually killing it in the process. The lysogenic pathway involves the virus inserting itself into the bacterium's chromosome. At a later stage, the viral genome is activated, and it continues along the lytic pathway of producing and releasing progeny virions.
If so, CI represses the early promoters and the infection is shunted into the lysogenic pathway. N is an anti-termination factor that is needed for the transcription of the delayed early genes. Delayed early genes: These include the replication genes O and P and also Q , which encodes the anti-terminator responsible for transcription of all the ...
On initial infection, the stability of cII determines the lifestyle of the phage; stable cII will lead to the lysogenic pathway, whereas if cII is degraded the phage will go into the lytic pathway. Low temperature, starvation of the cells and high multiplicity of infection (MOI) are known to favor lysogeny (see later discussion).
Virus latency (or viral latency) is the ability of a pathogenic virus to lie dormant within a cell, denoted as the lysogenic part of the viral life cycle. [1] A latent viral infection is a type of persistent viral infection which is distinguished from a chronic viral infection. Latency is the phase in certain viruses' life cycles in which ...

Another important area of interest is the control of prophage gene expression with many of the lysogenic conversion genes (gene conversion) being tightly regulated. [15] This process is capable of converting non-pathogenic bacteria into pathogenic bacteria that can now produce harmful toxins [15] such as in staph infections. Since the specific ...
