title: [Comparative characteristics of spherical and filamentous virions of influenza virus type A].
abstract: An analysis of fractions of a reassortant of A/WSN/33 and A/duck/Hochimin/014/78 strains enriched with spherical and filamentous virions showed that spherical and filamentous virus particles differed by sucrose density gradient. The relative content of nucleocapsid protein in filamentous virions was slightly lower than in spherical ones which might be due to different volume/surface ratio of these particles. The results of UV-inactivation of filamentous and spherical virions suggest that the filamentous particles are multigenomic.
