Abstract

Algal polysaccharide obtained from carrageenin protects 80 to 100 percent of chicken embryos against fatal infections with the Lee strain of influenza virus. This report describes the rapid emergence of a stable variant of this virus which is resistant to the protective action of this polysaccharide.
