🔬 Lysogenic Infection

A reductive infection that results in ongoing phage genome replication, as a prophage, and specifically does not involve virion production except following subsequent prophage induction.

by Stephen T. Abedon Ph.D. Steve Abedon, Ph.D., has taught well over 100 individual classes and ~10 individual courses (including introductory biology, microbiology, physiology, biochemistry, etc.) over his 30+ years as a college professor. He has over 150 publications, including multiple monographs, and is ranked in the top 1 or 2 percent among researchers of all disciplines worldwide. His research focuses on bacteriophage biology and phage therapy. (abedon.1@osu.edu)

Lysogenic Infection: A reductive infection that results in ongoing phage genome replication, as a prophage, and specifically does not involve virion production except following subsequent prophage induction.

Discussion

Contrast with productive infections where phage replication is coupled with virion production. Contrast also with pseudolysogenic infections for which, as defined here, neither phage-genome replication nor virion production occurs. See also lysogen as well as lysogenic cycle, lysogenic bacterium, and lysogenic culture.

Note that lysogenic infections should not be equated with "temperate-phage infections" since temperate phages, by definition, are capable of not only lysogenic infections but productive infections as well. Indeed, the latter is often more prevalent than the former (e.g., cultures to which temperate phages have been added often lyse).
