title: [Isolation of the influenza virus from ducks in the Aral Sea region].
abstract: Influenza A/duck/Aralsk/1/78 virus was isolated from ducks in southwestern Kazakhstan. Typing of this virus neuraminidase indicated its appurtenance to the 2nd avian type. Hemagglutinin of A/duck/Aralsk/1/78 virus typed by the HI test showed no relationship with any one of the strains used in the test including H0, H1, H2, H3, Hsw1, Heq1, Heq2, viruses and strains with all 10 avian hemagglutinins. This suggests that hemagglutinin of A/duck/Aralsk/1/78 virus (Hav?Nav2) belongs to a new, hitherto unknown type.
