[Antigenic Characterization of Influenza A virus Isolated from Birds captured in Ontario, Quebec, and the Maritime Provinces During the 1977 Season] [Article in French] Show Full Record 821
Source: Revue Canadienne de Biologie. 1980 Jun;39(2):107-14. Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Disease reservoirs Isolation & purification Microbiology Wild birds Abstract: ON-LINE ABSTRACT ONLY: A total of 145 influenza A viruses were isolated from ducks, geese and passerine birds in Ontario, Quebec and the Maritimes in July-August 1977. Antigenic characterization of these isolates included five hemagglutinin (Hsw1, Hav4, Hav5, Hav6, Hav7) and five neuraminidase subtypes (N1, N2, Neq1, Neq2, Nav1) in nine different combinations; one combination Hav7 Neq1 had not been previously reported. The majority of these viruses were Hsw1 N1, antigenically related to influenz...
[Avian influenza virus] [Review] [Article in Japanese] Show Full Record 755
Source: Uirusu. 2004 Jun;54(1):93-6 Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Genetics Pathogenicity Poultry Zoonoses Abstract: ON-LINE ABSTRACT ONLY: Recent outbreaks of highly pathogenic avian influenza in chickens and ducks that occurred in 9 Asian countries including Japan alarmed to realize that there is no border for infections and gave a rise to great concern for human health as well as for agriculture. This H5N1 virus jumped the species barrier and caused severe disease with high mortality in humans in Viet Nam and Thailand; 15 deaths of 22 cases and 8 of 12, respectively. A second concern was the possibility tha...

Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza China Low pathogenic avian influenza Migratory birds Siberia Virology Abstract: From abstract (online abstract only): Since 1979, the group belonging to Departments of Veterinary Microbiology, Veterinary Public Health and the Avian Zoonoses Research Centre, Faculty of Agriculture, Tottori University is continuing isolation of avian influenza virus from such migratory waterfowls as whistling swan, pintail and tufted dugs flying from Siberia and/or northern China. They have already isolated many interesting influenza viruses. Serotype of the isolates is various; some H5 and H...
[Isolation of Avian Influenza from Migratory Waterfowl in Germany: Results of a Two Year Study] [Acticle in German] Show Full Record 1184

More than 3.000 samples of 79 different species of wild birds (migratory and resident birds) were taken and 1.151 established pools investigated. Samples came from 80 different regions of Germany. Forty AIV isolates representing 14 combinations of eight different hemaggluti...

Resource Type(s): Journal (Articles) Searchable Keywords: Analysis aspects Avian influenza China Abstract: From abstract (online abstract only): OBJECTIVE: To analyze the spatial distribution of highly pathogenic avian influenza (HPAI) and to explore environmental factors associated with HPAI using geographic information system (GIS) techniques in Mainland China. METHODS: Databases were set up using the information of HPAI during epidemics in 2004, and linked to digital maps at provincial and county administrative layers in the country through the ArcGIS 8.3 software. Spatial cluster analyses, spatia...
A Blood Test for Prion: Disease Associated Prion Aggregate is Detected in the Blood of Infected But Asymptomatic Animals Show Full Record 1798
Source: Clinical Vaccine Immunology. 2006 Nov 1 [Epub ahead of print] Resource Type(s): Journal (Articles) Searchable Keywords: Blood Chronic wasting disease Deer Detection Diagnosis Diagnostic testing Immunoassays PrPSc proteins Test developments Abstract: From abstract (online abstract only): We have developed a sensitive in vitro assay for detecting disease associated prion aggregates by combining an aggregation specific enzyme-linked immunosorbent assay (AS-ELISA) with a Fluorescent Amplification Catalyzed by T7 RNA polymerase Technique (FACTT). The new assay, named AS-FACTT, is much more sensitive than AS-ELISA and could detect prion aggregates in the brain of mice as early as 7 days after an intra-peritoneal inoculation of PrPSc. However, AS-...
A Case of Chronic Wasting Disease in an Elk Imported to Korea from Canada Show Full Record 390

Resource Type(s): Journal (Articles) Searchable Keywords: Canada Central nervous system Chronic wasting disease Deer Diagnosis Isolation & purification Korea Transportation (animal) Western blotting Abstract: From abstract (free full-text available): A seven-year-old male elk (Cervus elaphus nelsoni) was euthanized and necropsied after having a 3-week history of body weight loss, emaciation, excessive salivation, teeth grinding, fever, anorexia, and respiratory distress. The elk was imported into Korea from Canada on March 9, 1997. Gross pathologic findings were restricted to a diffuse fibrinous pneumonia. Microscopic lesions included mild neuronal vacuolation and spongiform change in the neuropil of...

A General Model of Prion Strains and Their Pathogenicity Show Full Record 3084
Source: Science. 2007 Nov 9;318(5852):930-6. Resource Type(s): Journal (Articles) Searchable Keywords: Pathogenicity Prion diseases Prion protein Abstract: From abstract (online abstract only): Prions are lethal mammalian pathogens composed of aggregated conformational isomers of a host-encoded glycoprotein and which appear to lack nucleic acids. Their unique biology, allied with the public-health risks posed by prion zoonoses such as bovine spongiform encephalopathy, has focused much attention on the molecular basis of prion propagation and the "species barrier" that controls cross-species transmission. Both are intimately linked to understanding ...
A Multiplex RT-PCR for Detection of Type A influenza Virus and Differentiation of Avian H5, H7, and H9 Hemagglutinin Subtypes Show Full Record 1293
