title: [Isolation and characteristics of cloned variants of influenza virus A/USSR/13/81 (H1N1-N3)].
abstract: Cloning in chick embryos and MDCK cell culture of influenza A/USSR/13/81 (H1N1-N3) virus isolated during virological examinations of autopsy materials from a child who had died from acute respiratory virus infection yielded three subpopulations of clones differing in antigenic, biological, physico-chemical properties and glycoprotein structures. One subpopulation contained hemagglutinin (HA) similar to that of the A/PR/8/34 strain and neuraminidase (NA) N3, the other HA similar to that of A/WS/33 and NA N1, and the third HA of the isolate proper and NA of the both serosubtypes mentioned.
