Induction: The conversion of a lysogenic infection into a productive infection.

Discussion

<p>Temperate phage life cycles involve multiple, often conflicting steps with the induction step being one that transitions the phage from a state in which their success is intimately tied to that of their bacterial host, over longer time frames, to a state in which they function instead explicitly as antibacerial antagonists.

This is the definition from Adams (1959), p. 440, "The transition from the prophage to the vegetative state in lysogenic bacteria, occurring spontaneously or after wikipedia.org/wiki/Experiment" target="_blank" class="bap-term">experimental application of inducing agents."

For additional discussion and references, see Little (2005), Ptashne (2004), etc.
