| avian influenza virus wild bird surveillance in the azov and black sea regions of ukraine (2010-2011). | the azov and black sea basins are part of the transcontinental wild bird migration routes from northern asia and europe to the mediterranean, africa, and southwest asia. these regions constitute an area of transit, stops during migration, and nesting for many different bird species. from september 2010 to september 2011, a wild bird surveillance study was conducted in these regions to identify avian influenza viruses. biological samples consisting of cloacal and tracheal swabs and fecal samples ... | 2012 | 23402128 |
| wood ducks (aix sponsa) as potential reservoirs for avian influenza and avian paramyxoviruses. | influenza a viruses (iavs) and avian paramyxoviruses (apmvs) are important pathogens of poultry worldwide, and both commonly occur in wild waterfowl, especially ducks in the family anatidae. although wood ducks (aix sponsa) are members of the anatidae, their behaviour differs from most other species in this family, which could affect the transmission of iavs and apmvs. we collected cloacal and oropharyngeal swab and blood samples from more than 700 wood ducks across nine states in the eastern un ... | 2015 | 25695149 |
