Abstract
Coinfection of mouse L cells with vaccinia virus rescues encephalomyocarditis virus (EMC) from the inhibitory effect of interferon (IFN). The vaccinia-mediated rescue of EMC growth increases the yield of EMC as much as 1000-fold and is optimum when vaccinia is used at a multiplicity of infection of 1. This rescue correlates with a vaccinia-dependent stimulation of EMC gene expression. Evidence is presented to indicate that the rescue by vaccinia does not involve a block of the 2'-5'A synthetase pathway. However, the vaccinia rescue function is correlated with a vaccinia-mediated inhibition of the IFN-induced protein kinase.
