COMPARATIVE STUDIES OF INFLUENZA A (H_3N_2) ISOLATED FROM PIG AND HUMAN Ⅱ CHARACTERIZATION OF BIOLOGICAL PROPERTIES
Abstract: The influenza A viruses(H_3N_2)isolated from pigs each year were antigenically indistinguishable from contemporary human isolates in 1979-1982,the characteristics of biological properties were also similar.The results showed that haemagglutinins of pig strains were similar to human strains by being heat sentively,agglutining to the rang of animals red blood cells,sentively of pH etc. There were some differences between the strains in various years by agglutinated various animals red blood cells.The dove red...
