Source: Bulletin of the World Health Organization. 1974;51(4):325-32. Resource Type(s): Journal (Articles) Searchable Keywords: Animals Avian influenza Birds Genetic recombination Influenza A Virus Microbiology Serotyping USSR Abstract: From abstract (free full-text available): Six avian influenza A viruses isolated in the USSR were chaaracterized antigenically by using specific antisera to the isolated surface subunits of the known reference strains. Three of the viruses, all isolated from the same region, were characterized as A/duck/Ukraine/63 (Hav7 Neq2), and a virus isolated from a crow was of the Hong Kong/68 (H3 N2) type. The remaining two viruses were novel in that they possessed Hav7 Nav2 antigens, a combination that ...

A Pathogenesis Study of Highly Pathogenic Avian Influenza Virus H5N2 in Chickens, Using Immunohistochemistry Show Full Record 1870

Resource Type(s): Journal (Articles) Searchable Keywords: Analysis aspects Animals Antigens Avian influenza Brain Chickens Immunohistochemistry Immunology Influenza A Virus Influenza A Virus, H5N2 subtype Influenza in birds Pathogenicity Pathology Abstract: From abstract (online abstract only): Eighteen specific pathogen-free chickens (nine hens older than 1 year and nine 15-week-old males) were inoculated with highly pathogenic avian influenza virus A/Chicken/Pennsylvania/1370/1983 (H5N2). Birds were serially killed and tissues collected for histological and immunohistochemical evaluation. In the group of older hens, disease was acute or peracute. By immunohistochemistry, antigen was abundant in capillary endothelium in multiple organs, and staini...
A Simple Restriction Fragment Length Polymorphism-based Strategy that Can Distinguish the Internal Genes of Human H1N1, H3N2, and H5N1 Influenza A Viruses Show Full Record 1563
Source: Journal of Clinical Microbiology. 2000 Jul;38(7):2579-83 Resource Type(s): Journal (Articles) Searchable Keywords: Animals Avian influenza Genes Genetics Hong Kong Humans Influenza A Virus Influenza A Virus, H5N1Subtype Outbreaks Virology Abstract: From abstract (free full-text available): A simple molecular technique for rapid genotyping was developed to monitor the internal gene composition of currently circulating influenza A viruses. Sequence information from recent H1N1, H3N2, and H5N1 human virus isolates was used to identify conserved regions within each internal gene, and gene-specific PCR primers capable of amplifying all three virus subtypes were designed. Subtyping was based on subtype-specific restriction fragment length polymo...
A Virus Reveals Population Structure and Recent Demographic History of its Carnivore Host Show Full Record 1913
Source: Science. 2006 Jan 27;311(5760):538-41. Resource Type(s): Journal (Articles) Searchable Keywords: Alberta Animals Avian influenza Bayes Theorem British Columbia Ecosystem Genes Genetics Geography Molecular evolution Molecular structure Montana Phylogeny Population dynamics Time factors Veterinary medicine Wyoming Abstract: From abstract (online abstract only): Directly transmitted parasites often provide substantial information about the temporal and spatial characteristics of host-to-host contact. Here, we demonstrate that a fast-evolving virus (feline immunodeficiency virus, FIV) can reveal details of the contemporary population structure and recent demographic history of its natural wildlife host (Puma concolor) that were not apparent from host genetic data and would be impossible to obtain by other means. We s...

Neuraminidase inhibition titres of some sera were high and the avidity of the inhibitor was comparable to that of specific antibody. The neuraminidase of A/Hong Kong/1/68 (H3N2), which was undergone considerable antigenic drift in man since 1957, was inhibited to a lesser extent by the bird sera, while the neuramini...

Antigenic and Genetic Analyses of H5 Influenza Viruses Isolated from Ducks in Asia Show Full Record 1862

Resource Type(s): Journal (Articles) Searchable Keywords: Animals Antibodies Antigens Avian influenza Chicken China Ducks Genes Genetics Hemagglutinin glycoproteins Hong Kong Humans Influenza A Virus Japan Phylogeny RNA Virology Abstract: From abstract (online abstract only): The hemagglutinin (HA) of six H5 influenza virus strains isolated from ducks in Japan and China in 1976 to 1996 were analyzed antigenically and genetically. Antigenic analysis using a panel of monoclonal antibodies revealed that the HA of H5 influenza viruses isolated from ducks are antigenically closely related to each other. Phylogenetic analysis indicates that the isolates from ducks in Hokkaido were derived from an ancestor common with the highly pathoge...

Resource Type(s): Journal (Articles) Searchable Keywords: Amino acid sequence Animals Antibodies Avian influenza Base sequence Comparative studies Ducks Hemagglutinins Humans Immunology Influenza A Virus Japan Microbiology Abstract: From abstract (online abstract only): The hemagglutinins of H3 influenza viruses isolated from migratory ducks on the Pacific flyway in Japan during the period 1977 to 1985 were analyzed antigenically and genetically. Antigenic analysis using monoclonal antibodies to the hemagglutinins of A/Aichi/2/68 (H3N2) and A/duck/Hokkaido/8/80 (H3N8) viruses showed that antigenic drift occurred extensively in human strains, whereas the hemagglutinins of duck viruses were highly conserved. It was also found... |
