U.S. to create a bird flu virus mutation 24 Mar 2005 The U.S. Centers for Disease Control and Prevention has begun a series of experiments to see how likely the bird flu virus could result in a human pandemic. The six-month series of experiments seeks to simulate the mixing and matching of genes from the H5N1 avian flu virus that has plagued Asia and a common human flu virus that public-health experts fear could turn avian flu into a pandemic, the Wall Street Journal reported Thursday.
CDC scientists inside an ultra-secure laboratory (?!?) have started swapping the genes of the H5N1 avian virus with the genes of an H3N2 virus, the strain behind most recent human flu outbreaks. Gene From 1918 Virus Proves Key to Virulent Influenza (University of Wisconsin Press Release) 06 Oct 2004 "Using a gene resurrected from the virus that caused the 1918 Spanish influenza pandemic, recorded history's most lethal outbreak of infectious disease, scientists have found that a single gene may have been responsible for the devastating virulence of the virus. Writing Oct. 7 in the journal Nature, virologist Yoshihiro Kawaoka of the University of Wisconsin-Madison and the University of Tokyo, describes experiments in which engineered viruses were made more potent by the addition of a single gene. The work is evidence that a slight genetic tweak is all that is required to transform mild strains of the flu virus into forms far more pathogenic and, possibly, more transmissible...
Using a comparatively mild form of influenza A virus as a template, Kawaoka's team added the two 1918 genes that code for hemagglutinin and neuraminidase and infected mice with the engineered viruses." http://www.legitgov.org/flu_oddities.html#flu_hot_articlesLori Price
