| avian influenza viruses in wild birds at the jeziorsko reservoir in poland in 2008-2010. | during a 3-year surveillance study for avian influenza virus (aiv) infections at the jeziorsko reservoir in central poland, 549 oropharyngeal or cloacal swabs from 366 birds of 14 species belonging to 3 orders (anseriformes, charadriiformes and gruiformes) were tested. aiv was detected in 14 birds (3.8%): common teals (12x), mallard (1x) and garganey (1x). three potentially dangerous h5 aiv were detected in common teals (2x) and garganey (1x) but all of them revealed a low pathogenic pathotype. ... | 2012 | 22844711 |
| surveillance for avian influenza virus in wild birds in poland, 2008-15. | we tested wild birds in poland during 2008-15 for avian influenza virus (aiv). we took 10,312 swabs and feces samples from 6,314 live birds representing 12 orders and 84 bird species, mostly from orders anseriformes and charadriiformes, for testing and characterization by various pcr methods. from pcr-positive samples, we attempted to isolate and subtype the virus. the rna of aiv was detected in 1.8% (95% confidence interval [ci], 1.5-2.1%) of birds represented by 48 mallards ( anas platyrhyncho ... | 2017 | 28094608 |
| surveillance and identification of influenza a viruses in wild aquatic birds in the crimea, ukraine (2006-2008). | the ecology of avian influenza (ai) viruses in wild aquatic birds of asia is poorly understood, especially for the h5n1 high pathogenicity ai (hpai) viruses. from march 2006 through november 2008, 20 ai viruses were isolated in the crimea region of ukraine with an overall frequency of virus recovery of 3.3%. all the viruses were isolated from three species of dabbling ducks: mallard (anas platyrhynchos), wigeon (anas penelope), and garganey (anas querquedula), making the frequency of virus recov ... | 2010 | 20945793 |
| [infection of pigs with influenza a/h4 and a/h5 viruses isolated from wild birds on the territory of russia]. | pigs were intranasally infected with avian influenza a/h5 (h5n1, h5n3) and a/h4 (h4n6, h4n8) viruses in mono- and coinfection. infection with both apathogenic and pathogenic strains caused no clinical manifestations. a virus and/or fragments of its genome retained in nasopharyngeal fluid as long as 6-8 days after infection. during monoinfection, the structure of the hemagglutinin (ha) receptor site of isolates from the pigs infected with a/h5n1 strains (a/chicken/kurgan/3/2005, a/duck/russia/535 ... | 2008 | 19172904 |
| [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 |
| [complex environmental and virological monitoring in the primorye territory in 2003-2006]. | the paper presents the results of monitoring of viruses of western nile (wn), japanese encephalitis (je), tick-borne encephalitis (tbe), geta, influenza a, as well as avian paramicroviruses type i (virus of newcastle disease (nd)) and type 6 (apmv-6) in the primorye territory in 2003-2006. totally throughout the period, specific antibodies to the viruses were detected by neutralization test in wild birds (7.3%, wn; 8.0%, geta; 0.7% batai; 2.8%, alpine hare (lepus timidus); by hemagglutination-in ... | 2007 | 18041224 |
| [genetic variety of influenza a virus in the populations of wild birds in the south of western siberia]. | influenza a virus variants belonging to h3 and h4 subtypes were isolated from wild ducks inhabiting in the south of western siberia. phylogenetic analysis of hemagglutinin (ha) gene of these viruses has revealed that h3 isolates are closely related to those isolated from the bird inhabiting in west europe (a/teal/germany/wv01r/01, a/duck/ukraine/1/63) and china (a/aquatic bird/hong kong/399/99); and those isolated from the birds inhabiting in germany (a/garganey/germany/wv157k/01, a/teal/germany ... | 2005 | 16104520 |
