Abstract: | Summary The infectivity of herpes simplex virus type 1 (HSV-1) was found to be markedly reduced by treating virions with the tertiary amine local anesthetics lidocaine, dibucaine and tetracaine. These treatments induced a characteristic shift in the buoyant density of the HSV-1 particles from a light to a heavy population. HSV-1 virions were unstable at alkaline pH, and alkali treatment caused the same shift in buoyant density. Ca2+ stabilized the light population. These results suggest that the physicochemical status of the HSV-1 envelope which is sensitive to the treatments described above plays an important role for the integrity of the virion. |
