Studying the pathogenicity of avian influenza virus subtype H5N1 strains from the Russian Federation using mouse model.

The pathogenicity of strains of avian influenza virus subtype H5N1 from the Russian Federation (A/turkey/Suzdalka/12/05, A/goose/Krasnoozerskoye/627/05, A/duck/Tuva/ 01/06, A/chicken/Reshoty/02/06, and A/chicken/Krasnodar/123/060) was studied in mice. Morphological and immunological characteristics of experimental viral infection with avian influenza virus subtype H5N1 were evaluated.
