[Influenza virus sensitivity to interferon and its inducer].

The results of the study on influenza virus sensitivity to interferon of two kinds (human and chicken) and its inducer, poly(G) . poly(C) are presented. Differences in this characteristic among human and animal influenza viruses were demonstrated. There was a correlation between sensitivity to poly(G) . poly(C)-induced interferon and sensitivity to chicken interferon. Comparative studies of sensitivity to interferon in parent viruses and recombinants demonstrated that recombinants derived this property from one of the parental strains.
