Abstract— Enhanced reactivation of UV- and y-irradiated herpes virus was investigated by the plaque assay onCV–1 monkey kidney monolayer cells irradiated with UV light or X-rays. Both UV- and X-irradiatedCV–1 cells showed enhancement of survival of UV-irradiated virus, while little or no enhancement was detected for y-irradiated virus assayed on UV- or X-irradiated cells. The enhanced reactivation of UV-irradiated virus was greater when virus infection was delayed 24 or 48 h, than for infection immediately following the irradiation of cells. It is demonstrable that the UV- or X-irradiatedCV–1 cells are able to enhance the repair of UV damaged herpes virus DNA, but not of y-ray damaged ones. 相似文献
