A programme for the construction of a lambda phage.

W J Brammar, C Hadfield

    Journal of Embryology and Experimental Morphology
    |November 1, 1984

    Summary

    Lambdoid coliphage infection offers two outcomes: bacterial cell lysis or lysogeny, where viral DNA integrates into the host. Both pathways involve intricate host and phage coordination for developmental control.

    Area of Science:

    • Microbiology
    • Molecular Biology
    • Virology

    Background:

    • Lambdoid coliphages infect bacterial hosts, leading to distinct cellular fates.
    • Bacterial infection can result in cell lysis or lysogeny, a state of stable viral DNA integration.

    Purpose of the Study:

    • To review the lytic and lysogenic pathways of lambdoid coliphage infection.
    • To emphasize the control mechanisms governing the commitment to a specific pathway.

    Main Methods:

    • Review of existing literature on lambdoid coliphage infection.
    • Analysis of host and phage functions involved in infection outcomes.

    Main Results:

    • Lambda infection follows a highly regulated developmental plan.
    • Alternative responses (lysis vs. lysogeny) necessitate coordinated host-phage interactions.

    Conclusions:

    • The commitment to either the lytic or lysogenic pathway is determined by complex control mechanisms.
    • Understanding these mechanisms is crucial for comprehending viral-bacterial interactions.
