[Isolation of strains of the Hong Kong complex (H3N2) influenza virus from Nyctalus noctula bats in Kazakhstan].

Four antigenically related hemagglutinating agents were isolated from pools of lungs and tracheas of Nyctalus noctula bats in chick embryos. Identification of the isolates by the hemagglutination inhibition, neuraminidase activity inhibition and double immunodiffusion methods revealed close antigenic relationships with A/Port Chalmers/73 virus.
