[molecular genetic analysis of the biological properties of highly pathogenic influenza a/h5n1 virus strains isolated from wild birds and poultry during epizooty in western siberia (july 2005)].the full-size genomes of 2 highly pathogenetic avian influenza (hpai) virus strains isolated from a wild great-crested grebe (a/grebe/novosibirsk/29/05) and a domestic duck (a/duck/novosibirsk/56/05) in the tract of the chany hollow, barabino forest-steppe (novosibirsk region) during the epizootic outbreak in the summer of 2005. the reproductive properties of these strains successively increase in the series of cell lines bhk-2 --> leh --> vero-e6 --> mdck --> ps. a/grebe/novosibirsk/29/05 and a ...200616756172
[isolation of highly pathogenic avian influenza (hpai) a/5h5n1 strains from wild birds in the epizootic outbreak on the ubsu-nur lake (june 2006) and their incorporation to the russian federation state collection of viruses (july 3, 2006)].virological and molecular genetic studies of the field material collected in the epicenter of epizooty with high mortality rates among the wild birds on the coast of the ubsu-nur lake (republic of tyva, 51 degrees nl, 93 degrees el, june 2006) revealed the etiological role of highly pathogenic avian influenza (hpai) h5n1. seven hpai/h5n1 strains were isolated from the tracheal/cloacal swabs of clinically healthy, ill and recently dead great-crested grebes (podiceps cristatus), cormorants (phalac ...200617214076
first case of highly pathogenic h5n1 avian influenza virus in spain.the h5n1 strain of avian influenza virus has been involved in severe mortality in domestic poultry, and has also been found in different species of wildlife in europe. the basque country avian influenza surveillance program began sample collection and processing the fall of 2005.200819077185
risk assessment applied to spain's prevention strategy against highly pathogenic avian influenza virus h5n1.notifiable avian influenza (nai) had never been reported in spain, until july 2006 when a dead great crested grebe (podiceps cristatus) was found positive to the highly pathogenic h5n1 subtype as part of the active wild bird surveillance plan. the current program of the spanish ministry of agriculture, fisheries, and food (mapa)'s strategic preventive plan against nai is divided in the following parts: identification of risk areas and risk wild bird species, increased biosecurity measures, early ...200717494621
[the first break-through of the genotype 2.3.2 of high-virulence influenza a virus a/hsn1, which is new for russia, in the far east].the epizootic etiologically associated with highly pathogenic avian influenza h5n1 genotype 2.3.2 that is new for russia among wild and domestic birds in the south of the primorye territory during spring migration in april 2008 has been decoded. about 25% of the wild birds of a water complex, which include european teals (anas crecca), mallard ducks (anas platyrhynchos), great-crested grebes (podiceps cristatus), are involved in viral circulation in the area of the suifun-khankai plain. chicken ...200819069785
highly (h5n1) and low (h7n2) pathogenic avian influenza virus infection in falcons via nasochoanal route and ingestion of experimentally infected experimental infection with highly pathogenic avian influenza (hpai) and low pathogenic avian influenza (lpai) viruses was carried out on falcons in order to examine the effects of these viruses in terms of pathogenesis, viral distribution in tissues and viral shedding. the distribution pattern of influenza virus receptors was also assessed. captive-reared gyr-saker (falco rusticolus x falco cherrug) hybrid falcons were challenged with a hpai h5n1 virus (a/great crested grebe/basque country/0 ...201222427819
