n that reassortment events involving inter-species transmission are necessary steps in the evolution of new pandemic strains. However, it is not always clear in which species these events occur. Monitoring for reassortant viruses should therefore include as important target species both pigs and poultry. Several molecular markers in influenza virus genes have been reported to be associated with biological properties related to virulence and transmission. However, these associations have been inc
