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.

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, with the latter often more prevalent than the former (e.g., cultures to which temperate phages have been added often lyse).
