Genetic and antigenic characterization of H5 and H7 influenza viruses isolated from migratory water birds in Hokkaido, Japan and Mongolia from 2010 to 2014

Migratory water birds are the natural reservoir of influenza A viruses. H5 and H7 influenza
viruses are isolated over the world and also circulate among poultry in Asia. In 2010, two
H5N1 highly pathogenic avian influenza viruses (HPAIVs) were isolated from fecal samples
of water birds on the flyway of migration from Siberia, Russia to the south in Hokkaido,
Japan. H7N9 viruses are sporadically isolated from humans and circulate in poultry in
China. To monitor whether these viruses have spread in the wild bird population, we …

Genetic and antigenic characterization of H5 and H7 avian influenza viruses isolated from migratory waterfowl in Mongolia from 2017 to 2019

The circulation of highly pathogenic avian influenza viruses (HPAIVs) of various subtypes
(eg, H5N1, H5N6, H5N8, and H7N9) in poultry remains a global concern for animal and
public health. Migratory waterfowls play important roles in the transmission of these viruses
across countries. To monitor virus spread by wild birds, active surveillance for avian
influenza in migratory waterfowl was conducted in Mongolia from 2015 to 2019. In total,
5000 fecal samples were collected from lakesides in central Mongolia, and 167 influenza A …
