Differences in interfering activities were demonstrated between low-passage epidemic and thermosensitive cold-adapted strains of influenza viruses A and B in experiments on chick embryos inoculated on the chorioallantoic membranes and on white mice. At a high multiplicity of infection the thermosensitive variants showed a higher interfering activity as compared with the original viruses which had undergone a limited number of chick embryo passages.
