| no evidence that migratory geese disperse avian influenza viruses from breeding to wintering ground. | low pathogenic avian influenza virus can mutate to a highly pathogenic strain that causes severe clinical signs in birds and humans. migratory waterfowl, especially ducks, are considered the main hosts of low pathogenic avian influenza virus, but the role of geese in dispersing the virus over long-distances is still unclear. we collected throat and cloaca samples from three goose species, bean goose (anser fabalis), barnacle goose (branta leucopsis) and greater white-fronted goose (anser albifro ... | 2017 | 28542340 |
| epidemic of wild-origin h1nx avian influenza viruses in anhui, china. | as the natural hosts of avian influenza viruses (aivs), aquatic and migratory birds provide a gene pool for genetic transfer among species and across species, forming transient "genome constellations." this work describes the phylogenetic dynamics of h1nx based on the complete molecular characterization of eight genes of viruses that were collected from 2014 to 2015 in anhui province, china. | 2017 | 28669354 |
| new h6 influenza virus reassortment strains isolated from anser fabalis in anhui province, china. | h6 subtype avian influenza viruses are globally distributed and, in recent years, have been isolated with increasing frequency from both domestic and wild bird species as well as infected humans. many reports have examined the viruses in the context of poultry or several wild bird species, but there is less information regarding their presence in migratory birds. | 2017 | 28222765 |
| characterization of a reassortant h11n9 subtype avian influenza virus isolated from bean goose along the east asian-australian flyway. | during the surveillance of avian influenza viruses in the dongxi lake wetland of hubei in 2015-2016, an h11n9 avian influenza virus was isolated from a bean goose (anser fabalis). phylogenetic analysis showed that the ha gene of this isolate belongs to the north american lineage; however, the na and the internal genes of the isolate were generated from the eurasian lineage. this strain had reduced pathogenicity in mice and was capable of replication in the mouse lung without prior adaptation. th ... | 2017 | 27730427 |
| [monitoring influenza a virus and newcastle disease virus in migratory waterfowls in sanjiang natural reserve of heilongjiang province]. | in order to monitor the present situation of avian influenza virus (aiv) and newcastle disease virus (ndv) in migratory waterfowls effectively, 158 tracheal and cloacal swab samples for wild birds were collected from sanjiang natural reserve during migratory seasons in october 2005, april 2006 and october 2006. | 2008 | 19160826 |
| spatial, temporal, and species variation in prevalence of influenza a viruses in wild migratory birds. | although extensive data exist on avian influenza in wild birds in north america, limited information is available from elsewhere, including europe. here, molecular diagnostic tools were employed for high-throughput surveillance of migratory birds, as an alternative to classical labor-intensive methods of virus isolation in eggs. this study included 36,809 samples from 323 bird species belonging to 18 orders, of which only 25 species of three orders were positive for influenza a virus. informatio ... | 2007 | 17500589 |
| complete genome sequence of a natural reassortant h9n2 avian influenza virus found in bean goose (anser fabalis): direct evidence for virus exchange between korea and china via wild birds. | in 2011, we isolated a natural recombinant h9n2 avian influenza virus from fecal droppings of bean goose (anser fabalis) in korea. phylogenetic analyses showed that the a/bean goose/korea/220/2011(h9n2) isolate is a reassortant of eurasian and north american lineages of avian influenza virus. in addition, the complete genome sequence, including all 8 gene segments, was associated with chinese h9n2 viruses isolated from wild birds in the hunan east dongting lake national nature reserve. these dat ... | 2014 | 24953505 |
