We have analyzed the role of exogenous administration of mouse interferon (IFN alpha + beta) on the replication of vaccinia virus in peritoneal cells and in the spleen of Balb/c mice. Mice were pretreated for 16 hr with IFN and then infected with a vaccinia virus recombinant expressing luciferase under an early or late virus promoter, and the enzyme activity was measured in the course of virus infection. A dose of IFN as low as 10(3) units/mouse abolished the appearance of luciferase activity in cells of the peritoneal cavity and in spleen cells. The IFN-mediated inhibition of luciferase activity was observed even when mice were infected 4 days after the administration of IFN. The IFN-treated animals were considered free of virus since neither luciferase nor viral proteins were detected in target cells several days after virus infection. Despite a severe IFN-mediated inhibition of luciferase activity, the appearance of luciferase on mRNA levels was not inhibited 6 hr after virus infection. Our finding revealed that replication of vaccinia virus in Balb/c mice is exquisitively sensitive to inhibition by IFN and that this effect occurs at early times postinfection, most likely as a result of a translational block.
