Metabolic characteristics of cells infected with a herpesvirus of turkeys.
Chicken embryo fibroblasts infected with the nononcogenic herpesvirus of turkeys (HVT) displayed an increased rate of glucose uptake, a pronounced alteration of the pH of the medium, and an increased production of lactic acid when compared to mock-infected cultures. Objective estimates of cytopathology (quantifiable neutral red uptake and cell protein determination) showed that cell deterioration was a slow process in HVT-infected cells when compared to infection by herpes simplex virus. Experiments with irradiated host cells demonstrated that HVT required functional cell DNA for replication. The inactivation of the necessary host cell function displayed multihit kinetics. In agreement  with data on other herpesviruses, HVT damaged by UV light could be photoreactivated in chick cells. The results indicate that HVT shares biologic properties in common with other herpes and transforming viruses.
