| pathogenicity of a hong kong-origin h5n1 highly pathogenic avian influenza virus for emus, geese, ducks, and pigeons. | the h5n1 type a influenza viruses that emerged in hong kong in 1997 are a unique lineage of type a influenza viruses with the capacity to transmit directly from chickens to humans and produce significant disease and mortality in both of these hosts. the objective of this study was to ascertain the susceptibility of emus (dramaius novaehollandiae), domestic geese (anser anser domesticus), domestic ducks (anas platyrhynchos), and pigeons (columba livia) to intranasal (i.n.) inoculation with the a/ ... | 2002 | 11924603 |
| x-ray structure of the hemagglutinin of a potential h3 avian progenitor of the 1968 hong kong pandemic influenza virus. | we have determined the structure of the ha of an avian influenza virus, a/duck/ukraine/63, a member of the same antigenic subtype, h3, as the virus that caused the 1968 hong kong influenza pandemic, and a possible progenitor of the pandemic virus. we find that structurally significant differences between the avian and the human has are restricted to the receptor-binding site particularly the substitutions q226l and g228s that cause the site to open and residues within it to rearrange, including ... | 2003 | 12758169 |
