lysogeny

(noun)

the process by which a bacteriophage incorporates its nucleic acids into a host bacterium

Examples of lysogeny in the following topics:

  • Plasmids and Lysogeny

    • Both plasmids and lysogeny are used by bacteria and viruses to ensure transfer of genes and nucleic acids for viral reproduction.
    • Lysogeny is the process by which a bacteriophageintegrates its nucleic acids into a host bacterium's genome.
    • Lysogeny is utilized by viruses to ensure the maintenance of viral nucleic acids within the genome of the bacterium host.
    • Lysogeny is one of two major methods of viral reproduction utilized by viruses.
    • An example of a virus which can promote the transformation of bacterium from a nontoxic to toxic strain via lysogeny is the CTXφ virus.

  • Temperate Bacteriophages: Lambda and P1

    • With phage the term virulent is often used as an antonym to temperate, but more strictly a virulent phage is one that has lost its ability to display lysogeny through mutation, rather than a phage lineage with no genetic potential to ever display lysogeny (which more properly would be described as an obligately lytic phage).
    • In lysogeny, P1 can exist within a bacterial cell as a circular DNA, in that it exists by replicating as if it were a plasmid and does not cause cell death.
    • During lysogeny, new phage particles are not produced.
    • A unique feature of phage P1 is that during lysogeny its genome is not incorporated into the bacterial chromosome, as is commonly observed during lysogeny of other bacteriophage.
    • This virus is temperate and may reside within the genome of its host through lysogeny.

  • The Lytic and Lysogenic Cycles of Bacteriophages

    • Those phages able to undergo lysogeny are known as temperate phages.
    • Even though there are similarities between lysogeny and latency, the term lysogenic cycle is usually reserved to describe bacteriophages.

  • Bacteriophage Lambda as a Cloning Vector

    • This virus is temperate and may reside within the genome of its host through lysogeny.

  • Overview of Bacterial Viruses

    • Those phages able to undergo lysogeny are known as temperate phages.

  • Culture Media

    • The most common growth media nutrient broths (liquid nutrient medium) or LB medium (Lysogeny Broth) are liquid.
