Superinfection of polyoma virus-infected mouse embryo cells by beta-propiolactone-inactivated Sendai virus resulted in a 90% inhibition of the synthesis of infectious polyoma progeny. The interference is dependent upon the time of superinfection and the concentration of the inactivated virus. The inhibition of polyoma virus synthesis is transient in nature since normal synthesis of polyoma progeny virus is seen upon prolonged incubation. Interferon does not appear to be implicated in thedoi:10.1128/jvi.10.6.1091-1097.1972 fatcat:4r3debe5djg6liarxoo5kbf5qq
