25. The evolution of H5N1 influenza viruses in ducks in southern China
The pathogenicity of avian H5N1 influenza viruses to mammals has been evolving since the mid-1980s. Here, we demonstrate that H5N1 influenza viruses, isolated from apparently healthy domestic ducks in mainland China from 1999 through 2002, were becoming progressively more pathogenic for mammals, and we present a hypothesis explaining the mechanism of this ev

26. Emergence of multiple genotypes of H5N1 avian influenza viruses in Hong Kong SAR
Although A/Hong Kong/156/97 (H5N1/97)-like viruses associated with the “bird flu” incident in Hong Kong SAR have not been detected since the slaughter of poultry in 1997, its putative precursors continue to persist in the region. One of these, Goose/Guangdong/1/96 (H5N1 Gs/Gd)-like viruses, reassorted with other avian viruses to generate multiple genotyp

27. Characterization of the 1918 “Spanish” influenza virus neuraminidase gene
The “Spanish” influenza pandemic of 1918 was characterized by exceptionally high mortality, especially among young adults. The surface proteins of influenza viruses, hemagglutinin and neuraminidase, play important roles in virulence, host specificity, and the human immune response. The complete coding sequence of hemagglutinin was reported last year. Thi
