An influenza A virus of H4N6 subtype was isolated from the Izumi plain, Japan, in 2013. Genetic analyses revealed that two viral genes (M and NS gene segments) of this isolate were genetically distinct from those of the H4N6 virus isolated from the same place in 2012. Furthermore, three viral genes (PB2, PB1 and M gene segments) of this isolate share high similarity with those of the North American isolates of 2014. These results suggest a high frequency of genetic reassortment of avian influenza viruses in Asian waterfowl and intercontinental movements of avian influenza viruses via migratory waterfowl.
