title: Combined effect of acyclovir and amphotericin B on the replication of pseudorabies virus in BHK-21 cells.
abstract: Acyclovir, known as an antiherpetic agent, showed an inhibitory effect on the propagation of pseudorabies virus in BHK-21 cells. The antiviral effect of acyclovir was observed by plaque reduction, as well as by the inhibition of the virus-stimulated uptake of thymidine by BHK-21 cells. Amphotericin B potentiated the antiviral activity of acyclovir. The optimal concentrations of polyene antibiotic expressing the potentiating effect were lower than required for the induction of K+ leakage from the cells. There was no evident amphotericin B-induced stimulation of thymidine incorporation into infected BHK-21 cells. The model presented may be useful to study the potentiation phenomenon of polyene macrolide antibiotics.
