| surveillance and characterization of avian influenza viruses from migratory water birds in eastern hokkaido, the northern part of japan, 2009-2010. | avian influenza virus (aiv) surveillance was conducted around a small pond in obihiro, eastern hokkaido, japan. eleven aivs were isolated from a total of 1,269 fecal samples of migratory wild birds collected during 2009 and 2010. the sample number covered approximately 60 % of the total number of birds observed during sampling periods. the subtypes of the isolates included h3n8 (4 isolates), h5n2 (3), h6n2 (2), h6n1 (1), and h11n2 (1). the h3n8 subtype was most prevalent as in the previous studi ... | 2012 | 23264106 |
| genetic characterization of h5n2 influenza viruses isolated from wild birds in japan suggests multiple reassortment. | low-pathogenic avian influenza viruses (lpaivs) of the h5 subtype can mutate to highly pathogenic forms, potentially destabilizing the poultry industry. wild migratory birds are considered a natural reservoir of lpaivs capable of dispersing both high- and low-pathogenic forms of the virus. therefore, surveillance and characterization of aiv in wild birds are essential. here, we report on the isolation and genetic characterization of 10 aivs of the h5n2 subtype obtained through surveillance in ho ... | 2016 | 27573808 |
