Destruction of human retinoblastoma after treatment by the E variant of encephalomyocarditis virus.

The oncolytic effects of encephalomyocarditis (EMC) virus were examined in human retinoblastoma cell (Y79) cultures which were infected with 10(4 )tissue culture infectious doses (TCIDs) of the E variant of EMC (EMC-E) virus. The TCIDs were used to titer the maximum effect of EMC virus on L-929 cells. In-vitro studies showed 90% cytopathic effect (CPE) at 24 h and 100% CPE at 52 h.
