Lysogenic Cycle [9] An example of a virus that uses the lysogenic cycle to its advantage is the Herpes Simplex Virus. [10] After first entering the lytic cycle and infecting a human host, it enters the lysogenic cycle. This allows it to travel to the nervous system's sensory neurons and remain undetected for long periods of time.
Temperate phages can switch between a lytic and lysogenic life cycle. Lytic is more drastic, killing the host whereas lysogenic impacts host cells genetically or physiologically. [4] [5] [6] Here is a chart on temperate phages that are lytic and lysogenic and how they're related. Lysogeny is characterized by the integration of the phage genome ...
In the lytic cycle, the virus commandeers the cell's reproductive machinery. The cell may fill with new viruses until it lyses or bursts, or it may release the new viruses one at a time in an exocytotic process. The period from infection to lysis is termed the latent period. A virus following a lytic cycle is called a virulent virus.
In the lysogenic cycle, the phage chromosome is integrated as a prophage into the bacterial chromosome, where it can stay dormant for extended periods of time. If the prophage 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 ...
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 ...
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.
This is known as lysogenic viral reproduction. [2] Integration can result in a latent infection or a productive infection. In a productive infection, the provirus is transcribed into messenger RNA which directly produces new virus, which in turn will infect other cells via the lytic cycle.
Once a phage adsorbs to the surface of a bacteria, it may undergo either the lytic cycle or the lysogenic cycle. [6] Virulent phages enter the lytic cycle where they replicate and lyse the bacterial cell. [7] Virulent phages can differentiate between different species of bacteria based on their specific lytic action. [8]
