To estimate the timing of the reassortment events that led to the emergence of the H5N8 viruses in the Netherlands, we performed molecular dating (online Technical Appendix 2 Figure 3).
The H1N1 pandemic of 2009 is a good example in which the pandemic virus was a result of multiple reassortments between avian, human, and swine influenza viruses in pigs (2).
Although reassortment between swine influenza and 2009 influenza A (H1N1) has been reported in pigs, that particular genetic combination of swine influenza virus segments is unique, and has not been previously reported in swine or humans.
Liu and his colleagues, who published their findings in the Proceedings of the National Academy of Science, warned in their paper: 'The possibility of novel pandemic strains being generated from reassortment between avian H9N2 and H1N1/2009 influenza viruses exists.
The investigators noted that resistance-conferring mutations in an influenza A virus can occur as a result of drug selection, spontaneous mutation, or genetic reassortment with another drug-resistant influenza A virus (J.
First described in April 2009, the virus appeared to be a new strain of H1N1 which resulted when a previous triple reassortment of bird, pig and human flu viruses further combined with a Eurasian pig flu virus.
But, he added, some of those limitations are based on "unfounded fears of the risk of reassortment.
As Time magazine described it, Pigs make particularly good biological mixing bowls since they can be infected by bird-, swine- and human-flu viruses and provide a hospitable environment for the viruses to swap genes and create entirely new strains in a process called reassortment.
Reassortment is responsible for the repackaging errors that, in part, created the H1N1 pandemic influenza.
This phenomenon, called reassortment, is one of two possible phenomena that lead to "antigen shift," which results in immunologically unique viruses that produce pandemic influenza strains.
4 The swine flu virus occurred because of a genetic reassortment of four viruses from pigs, birds, and man.
It is therefore not too surprising that a novel swine influenza virus arose as a result of the exchange of genetic material, referred to as reassortment, from influenza viruses from swine, avian and human sources.
