Altered Tissue Tropism of Human-Avian Reassortant Influenza Viruses Show Full Record 807
Source: Virology. 1983 Jul 15;128(1):260-3. Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Ducks Enzymes Intestines Mammals Microbiology Physiology Viral hemagglutinins Abstract: ON-LINE ABSTRACT ONLY: Avian influenza viruses replicate to high titers in the cells lining the intestinal tract of birds; however, human strains do not. A series of reassortant viruses with all six internal genes from an avian strain and one or both genes for the surface antigens from a human strain failed to transit and infect the intestinal tracts of ducks. However, these reassortants did replicate in the bursa of ducks after rectal inoculation. These studies provide the first evidence that t...

Avian Flu: H5N1 Virus Outbreak in Migratory Waterfowl Show Full Record 743
Source: Nature. 2005 Jul 14; 436(7048):191-192. Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Bird diseases Disease transmission Epidemiology Humans Microbiology Migration (animals) Physiology Veterinary medicine Virology Wild birds Abstract: From abstract (free full-text available): A worrying development could help to spread this dangerous virus beyond its stronghold in southeast Asia. The highly pathogenic H5N1 influenza virus has become endemic in poultry in southeast Asia since 2003 and constitutes a major pandemic threat to humans1. Here we describe cases of disease caused by H5N1 and transmission of the virus among migratory geese populations in western China. This outbreak may help to spread the virus over and beyond the Hima...
Characterization of a Human H5N1 Influenza A Virus Isolated in 2003 Show Full Record 1680

Resource Type(s): Journal (Articles) Searchable Keywords: Animals Avian influenza Chickens China Comparative studies Ducks Ferrets Humans Influenza A Virus, H5N1Subtype Mice Molecular structure Outbreaks Physiology Poultry diseases Species specificity Veterinary medicine Virulence Virus cultivation Virus receptors Abstract: From abstract (free full-text available): In 2003, H5N1 avian influenza virus infections were diagnosed in two Hong Kong residents who had visited the Fujian province in mainland China, affording us the opportunity to characterize one of the viral isolates, A/Hong Kong/213/03 (HK213; H5N1). In contrast to H5N1 viruses isolated from humans during the 1997 outbreak in Hong Kong, HK213 retained several features of aquatic bird viruses, including the lack of a deletion in the neuraminidase stalk and...
Characterization of an Influenza A Virus from Seals Show Full Record 816
Source: Virology. 1981 Sep;113(2):712-24. Resource Type(s): Journal (Articles) Searchable Keywords: Birds Humans Influenza A Virus Mammals Microbiology Orthomyxoviridae infections Physiology Seals (animals) Veterinary medicine Abstract: From abstract (online abstract only): An influenza A virus antigenically similar to A/FPV/Dutch/27 (Hav1Neq1) [H7N7] was isolated from harbor seals (Phoca vitulina) that had died of acute hemorrhagic pneumonia on Cape Cod Peninsula, beginning in the winter of 1979?1980. High titers of virus were obtained from the lungs and lower titers from the brains of the seals. Although antigenic analyses and characterization of the RNAs show that all of the genes and gene products are closely related to dif...
Comparison of RNA Hybridization, Hemagglutination Assay, Titration of Infectious Virus and Immunofluorescence as Methods for Monitoring Influenza Virus Replication In Vitro Show Full Record 2058
Source: Journal of Virological Methods. 1998 Sep;74(1):57-66. Resource Type(s): Journal (Articles) Searchable Keywords: Animals Avian influenza Cell lines Dogs Fluorescent Antibody Technique Genetic techniques Hemagglutination Tests Hemagglutinins Humans Influenza A Virus Mammals Methods Nucleic Acid Hybridization Physiology RNA Virus receptors Virus replication Abstract: From abstract (online abstract only): Rapid and sensitive methods for the monitoring of influenza virus replication in vitro are needed to address several research questions. Four methods based on different principles were compared: the hemagglutination (HA) assay, the measurement of virus infectivity titers in culture supernatants, the enumeration of infected cells by immunofluorescence and RNA hybridization techniques using digoxigenin (DIG) labeled RNA probes. To this end, MDCK cells were inf...
Comparison of the Replication of Influenza A Viruses in Chinese Ring-Necked Pheasants and Chukar Partridges Show Full Record 987
Source: Journal of virology. 2006 Mar;80(5):2151-61. Resource Type(s): Journal (Articles) Searchable Keywords: Comparative studies Influenza A Virus Influenza in birds Physiology Poultry Virology Virus replication Abstract: From abstract (free full-text available): We investigated the replication and transmission of avian influenza A viruses in two species thought to be intermediate hosts in the spread of influenza A viruses in live poultry markets: Chinese ring-necked pheasants and chukar partridges. All 15 hemagglutinin subtypes replicated in pheasants, and most subtypes transmitted to naive contact pheasants, primarily via the fecal-oral route. Many viruses were shed from the gastrointestinal tract of experiment...
Crow Deaths Caused by West Nile Virus During Winter Show Full Record 3572
Source: Emerging Infectious Diseases. 2007 Dec;13(12):1912-4. Resource Type(s): Journal (Articles), Table or Spreadsheet Searchable Keywords: Bird diseases Crows Mortality New York Physiology Seasons Surveillance (monitoring) Virology West Nile virus Abstract: From abstractn (free full-text available): In New York, an epizootic of American crow (Corvus brachyrhynchos) deaths from West Nile virus (WNV) infection occurred during winter 2004-2005, a cold season when mosquitoes are not active. Detection of WNV in feces collected at the roost suggests lateral transmission through contact or fecal contamination. [Includes figures].
Differences Between Influenza Virus Receptors on Target Cells of Duck and Chicken and Receptor Specificity of the 1997 H5N1 Chicken and Human Influenza Viruses from Hong Kong Show Full Record 756
Source: Avian Diseases. 2003;47(3 Suppl):1154-60. Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Chickens Ducks Humans Influenza A Virus Influenza A Virus, H5N1Subtype Physiology Virus receptors Abstract: From abstract (online abstract only): To study whether influenza virus receptors in chickens differ from those in other species, we compared the binding of lectins and influenza viruses with known receptor specificity to cell membranes and gangliosides from epithelial tissues of ducks, chickens, and African green monkeys. We found that chicken cells contained Neu5Ac alpha(2-6)Gal-terminated receptors recognized by Sambucus nigra lectin and by human viruses. This finding explains how some recent ...
