[ugg classic tall fancy boots gray] The researchers discovered that some avian influenza viruses recovered from the North American pintails contain genes that are more closely related to influenza viruses in Eurasia, and that the greatest number of these genes occurred in pintail viruses from Alaska. In contrast, northern pintails sampled on their main wintering areas in California had few Eurasian virus genes.

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.

H5N1 is considered endemic in Egypt and parts of South East Asia.

For example, if a pig were infected with a human influenza virus and an avian influenza virus at the same time, the viruses could mix (reassort) and produce a new virus that had most of the genes from the human virus, but a hemagglutinin and/or neuraminidase from the avian virus.

Avian influenza viruses bind preferentially to sialyloligosaccharides with an ”2,3 linkage of N-acetylneuraminic acid to galactose (NAc”2,3Gal), whereas human influenza viruses prefer NAc”2,6Gal receptors, consistent with the fact that NAc”2 .

In 1968, a rearrangement occurred again where the virus acquired a new avian Hemagglutinin and caused the Hong Kong Flu.

Further, the researchers found that several of the same mutations that differentiated the 1918 virus from avian flu viruses are found in the H5N1 virus, which has killed more than 60 people in Asia.

Their results, including identification of the PB2 segment as a key to enhanced virulence, offer information likely to be useful in the event of a pandemic caused by a hybrid avian-human influenza strain.
