In vitro effect of isoprinosine on rabies virus.

The in vitro effect of isoprinosine, an antiviral compound, was evaluated on ERA and VA319 rabies viral strains. Isoprinosine diminished the number of immunofluorescent cells, viral titers, and structures involved in rabies virus replication. Mechanism of antiviral action was probably mediated by modification of the polyribosome conformation and function.
