[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...
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 Pathogenesis Study of Highly Pathogenic Avian Influenza Virus H5N2 in Chickens, Using Immunohistochemistry Show Full Record 1870
Source: Journal of Comparative Pathology. 1992 Oct;107(3):341-8. 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 Primate Model to Study the Pathogenesis of Influenza A (H5N1) Virus Infection Show Full Record 749
Source: Avian Diseases. 2003;47(3 Suppl):931-3. Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Influenza A Virus Influenza A Virus, H5N1Subtype Macaca fascicularis Monkeys Orthomyxoviridae infections Pathogenicity Physiopathology Virology Abstract: From abstract (online abstract only): Cynomolgus macaques (Macaca fascicularis) infected with influenza virus A/HongKong/156/97 (H5N1) developed acute respiratory distress syndrome (ARDS) with fever. Reverse transcriptase/polymerase chain reaction (RT/PCR) and virus isolation showed that the respiratory tract is the major target of the virus. The main lesion observed upon necropsy, performed 4 or 7 days postinfection, was a necrotizing bronchointerstitial pneumonia, similar to that found in prim...
A Review of Avian Influenza in Different Bird Species [Review] Show Full Record 716
Source: Veterinary Microbiology. 2000 May 22;74(1-2):3-13. Resource Type(s): Journal (Articles) Searchable Keywords: Ducks Great Britain Humans Influenza A Virus Isolation & purification Molecular sequence data Pathogenicity Turkeys Virology Abstract: From abstract (online abstract only): Only type A influenza viruses are known to cause natural infections in birds, but viruses of all 15 haemagglutinin and all nine neuraminidase influenza A subtypes in the majority of possible combinations have been isolated from avian species. Influenza A viruses infecting poultry can be divided into two distinct groups on the basis of their ability to cause disease. The very virulent viruses cause highly pathogenic avian influenza (HPAI), in which mortality ...

Antigenic and Phenotypic Variants of a Virulent Avian Influenza Virus Selected During Replication in Ducks Show Full Record 794
Source: Journal of Wildlife Diseases. 1989 Oct;25(4):507-13. Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Ducks Influenza A Virus Microbiology Pathogenicity Abstract: From abstract (free full-text available): To evaluate the replication of a highly virulent avian influenza A virus in a potential reservoir host, mallard ducks (Anas platyrhynchos) were inoculated with the virulent strain A/Ty/Ont/7732/66 (H5N9). Viruses recovered from the ducks were analyzed by hemagglutination inhibition (HI) and enzyme-linked immunosorbent assay (ELISA) and found to possess antigenically altered viral hemagglutinins. Plaque formation on the Madin-Darby Canine Kidney (MDCK) ce...
Are Seals Frequently Infected with Avian Influenza viruses? Show Full Record 805
Source: Journal of Virology. 1984 Sep;51(3):863-5. Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Influenza A Virus Microbiology Orthomyxoviridae infections Pathogenicity Seals (animals) Veterinary medicine Abstract: From abstract (free full-text available): Influenza A virus isolates of the H4N5 subtype (which has previously been detected only in birds) were recovered from harbor seals dying of viral pneumonia on the New England coast from June 1982 through March 1983. When these isolates were compared with other mammalian and avian viruses in serological assays and RNA-RNA competitive hybridization, it was found that the seal viruses were most closely related antigenically and genetically to recent avian v...
Assessment of the Ability of Ratite-origin Influenza Viruses to Infect and Produce Disease in Rheas and Chickens Show Full Record 1872

Resource Type(s): Journal (Articles) Searchable Keywords: Animals Avian influenza Birds Bronchi Chick embryo Chickens Comparative studies Fibroblasts Inflammation Influenza A Virus Influenza in birds Pathogenicity Species specificity Abstract: From abstract (free full-text available): Pathobiologic characteristics were determined for three mildly pathogenic (MP) ratite-origin avian influenza viruses (AIVs). Ratite-origin AIVs produced respiratory disease in rheas, and virus was reisolated from oropharyngeal and cloacal swabs on days 2-6 postinoculation. Inoculation of two ratite-origin AIVs in the upper respiratory tract of chickens resulted in viral infections, but the mean chicken infectious dose (CID50) for A/emu/Texas/39924/93 (H5... |
