Antigenic and Genetic Analyses of H1N1 Influenza A Viruses from European Pigs Show Full Record 782
Source: Journal of General Virology. 1997 Mar;78 ( Pt 3):553-62. Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Europe Genetic diversity Genetics Humans Immunology Influenza A Virus Influenza A Virus, H5N1Subtype Swine Viral antigens Viral hemagglutinins Abstract: From abstract (free full-text available): H1N1 influenza A viruses isolated from pigs in Europe since 1981 were examined both antigenically and genetically and compared with H1N1 viruses from other sources. H1N1 viruses from pigs and birds could be divided into three groups: avian, classical swine and 'avian-like' swine viruses. Low or no reactivity of 'avian-like' swine viruses in HI tests with monoclonal antibodies raised against classical swine viruses was associated with amino acid substitut...
Avian Flu: Multiple Introductions of H5N1 in Nigeria Show Full Record 1930
Source: Nature. 2006 Jul 6;442(7098):37. Resource Type(s): Journal (Articles) Searchable Keywords: Agriculture Animals Asia Avian influenza Disease transmission Europe Genetics Hemagglutinins Influenza A Virus, H5N1Subtype Influenza in birds Isolation & purification Migration (animal) Nigeria Phylogeny Poultry Russia Virology Abstract: From abstract (online abstract only): As the avian influenza virus H5N1 swept from Asia across Russia to Europe, Nigeria was the first country in Africa to report the emergence of this highly pathogenic virus. Here we analyse H5N1 sequences in poultry from two different farms in Lagos state and find that three H5N1 lineages were independently introduced through routes that coincide with the flight paths of migratory birds, although independent trade imports cannot be excluded.
Avian Influenza. Are Wild Birds to Blame? [NEWS] Show Full Record 1073

Migrating birds offer an obvious way to connect the dots of H5N1 outbreaks along the east coast of Asia and, in just the past few months, its unexpected cross-continent jump to Siberia, Kazakhstan, and Turkey. Moreover, researchers have long known that these birds commonly harbor less virulent flu viruses, and many w...

Characterization of a Novel Influenza A Virus Hemagglutinin Subtype (H16) Obtained from Black-headed Gulls Show Full Record 1456
Source: Journal of Virology. 2005 Mar;79(5):2814-22 Resource Type(s): Journal (Articles) Searchable Keywords: Amino acid sequence Animals Avian influenza DNA Europe Genes Hemagglutinins Immunology Influenza A Virus Isolation & purification Molecular structure Sweden Virology Abstract: From abstract (free full-text available): In wild aquatic birds and poultry around the world, influenza A viruses carrying 15 antigenic subtypes of hemagglutinin (HA) and 9 antigenic subtypes of neuraminidase (NA) have been described. Here we describe a previously unidentified antigenic subtype of HA (H16), detected in viruses circulating in black-headed gulls in Sweden. In agreement with established criteria for the definition of antigenic subtypes, hemagglutination inhibition assays and immuno...
Detection of H5 Avian Influenza Viruses by Antigen Capture ELISA Using H5-specific Monoclonal Antibody Show Full Record 2040
Source: Clinical and Vaccine Immunology. 2007 Mar 7; [Epub ahead of print] Resource Type(s): Journal (Articles) Searchable Keywords: Animals Asia Avian influenza Birds Disease transmission Europe Influenza A Virus, H5N1Subtype Isolation & purification Mammals Viral antibodies Abstract: From abstract (online abstract only): The unprecedented spread of highly pathogenic avian influenza (HPAI) subtype H5N1 in Asia and Europe is threatening animals and public health systems. Effective diagnosis and control management are needed to control the disease. To this end, we developed a panel of monoclonal antibodies (mAbs) against the H5N1 avian influenza virus (AIV) and implemented an antigen-capture ELISA (AC-ELISA) to detect H5 viral antigen. Mice immunized with denatured hemagglutini...
Do Hemagglutinin Genes of Highly Pathogenic Avian influenza Viruses Constitute Unique Phylogenetic Lineages? Show Full Record 1082
Source: Virology. 1995 Jun 1;209(2):664-70 Resource Type(s): Journal (Articles) Searchable Keywords: Asia Birds Comparative studies Europe Viral genes Viral hemagglutinins Abstract: From abstract (online abstract only): Avian influenza A viruses of the H5 and H7 subtypes periodically cause severe outbreaks of disease in poultry. The question we wished to address in this study is whether these highly pathogenic strains constitute unique lineages or whether they and related nonpathogenic viruses are derived from common ancestors in the wild bird reservoir. We therefore compared the nucleotide and amino acid sequences of the hemagglutinin (HA) genes of 15 H5 and 26 H7 influenz...
