Therefore, The study used molecular biology methods to express NS1 gene in the prokaryotic and eucaryotic expression systems, which provided base materials to research the function of NS1 gene.

Their neuraminidase protein (NA) carried substitutions in the hemadsorption (HB) site, similar to those of other avian H9N2 viruses from Asia, Middle Eastern and human pandemic H2N2 and H3N2 that bind to α -2, 6 -linked receptors.

In order to explore the genetic mutations of the hemagglutinin gene and the neuraminidase gene and the law of molecular epidemiology of H9 subtype avian influenza in China, Six influenza viruses were isolated from broilers in different parts of Shandong province in 2009,and explored their virulence, immune reference and the genetic mutations.

In order to comprehended and master the biological characteristics and the rules of homology and heredity evolution of H9N2 subtype avian influenza virus in ducks, the pathogenic, antigenic drifted and the rules of molecular genetic of the Dk/FQ107/07 strain were studied in the experiment, the theoretical and the experimental basis for prevention of H9N2 subtype avian influenza.The 50% embryo infective dose (EID50), mean dead time (MDT) and intravenous pathogenicity index (IVPI) have been conducted in order to demonstrate the pathogenicity of Dk/FQ107/07 strain.

Interestingly, we found that there is a difference in the translation of viral protein but not in the infectivity or transcription of viral genes of these H9N2 viruses in the infected cells.

[DNALC Blogs] Catching the Flu: Between Complacency and Fear: Candidates for such viruses are mostly avian viruses, most prominently the highly pathogenic H5N1 virus or “bird flu” (first isolated in Hong Kong in 1997) but also H9N2 and H7N7 viruses that infect humans sporadically. This scenario of avian viruses jumping into humans caused the pandemics of 1918, 1957 and 1968 (see Box 1) and can be imagined quite realistically in the recent movie, Contagion.

[ - Photown News] Deadly bird flu studies to stay secret for now: WHO - Health experts are concerned that the coexistence of human flu viruses and avian flu viruses (especially H5N1) will provide an opportunity for genetic material to be exchanged between species-specific viruses, possibly creating a new virulent influenza strain that is easily transmissible and lethal to humans. The mortality rate for humans with H5N1 is 60%.
