Dark reactivation in ultraviolet irradiated Escherichia coli.
Reversal of the lethal effect of ultraviolet radiation on microorganisms by a variety of treatments has been demonstrated with two essentially different plating techniques. Cells may be plated immediately after irradiation, in which case reactivation occurs on the agar plate. By employing such a plating procedure, reactivation has been accomplished through the use of heat (Anderson, 1951), acet...
متن کاملDark reactivation of ultraviolet-irradiated tobacco necrosis virus.
Some damage caused in tobacco necrosis virus by u.v. radiation could be repaired in darkness in Chenopodium amaranticolor (dark reactivation) but not in French bean or in tobacco. By contrast, photoreactivation of the irradiated virus was observed in French bean and in tobacco but not in Chenopodium. The kind of damage in u.v.-irradiated virus that is susceptible to repair by photoreactivation ...
متن کاملX-ray-enhanced reactivation of ultraviolet-irradiated human virus.
When CV-1 mammalian cells were X-irradiated before infection with ultraviolet (UV)-irradiated herpes simplex virus, an increase in survival of this virus was observed. X-ray reactivation is proposed as the name of this phenomenon by analogy with UV reactivation. The amount of survival enhancement was about the same as that found for UV reactivation in the same virus-host system. The enhancement...
متن کاملInteraction of encephalomyocarditis virus with ultraviolet-irradiated host cells.
Ultraviolet light (UV) impaired the capacity of L cells to support growth of encephalomyocarditis virus. The loss of capacity was partially restored by high multiplicity of infection (MOI). This phenomenon was not due to an increased probability of an infectious virus particle reaching a site of replication undamaged by UV, since UV-inactivated virus at high MOI induced restoration of the capac...
متن کاملUltraviolet-Irradiated Herpes Simplex Virus
L cells lacking thymidine kinase (TK) activity (Ltkcells) have been stably transformed to a TK-positive phenotype by infection with ultraviolet-irradiated herpes simplex virus (HSV-UV). The highest frequency of the Ltkto Ltk+ transformation observed in these experiments was approximately 10-3, whereas no measurable transformation was observed (less than 10-8) in the absence of HSV-UV infection....
