[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... ![[PDF]](images/icons/pdf.gif "Adobe Reader File"){kind=icon} A New Avian Influenza Virus from Feral Birds in the USSR: Recombination in Nature?

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 ... ![[IMAGE]](images/icons/image.gif "Image File"){kind=icon} A Normal Prion converting to an Abnormal Prion [Illustration] Show Full Record 2055

Abundant PrP(CWD) in tonsil from mule deer with preclinical chronic wasting disease. Show Full Record 374

Samples of formalin-fixed brain and tonsil tissues from mule deer were examined for PrP(CWD) using immunohistochemistry (IHC) with Mab F99/97.6.1, the gold standard for diagnosis of preclinical CWD. The contralateral tonsil from each of ...
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...

An Influenza A (H1N1) Virus, Closely Related to Swine Influenza Virus, Responsible for a Fatal Case of Human Influenza [Case Reports] Show Full Record 786

Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Comparative studies Genetics Human Influenza Influenza A Virus Influenza A Virus, H5N1Subtype Maryland Microbiology Swine Abstract: From abstract (free full-text available): In July 1991, an influenza A virus, designated A/Maryland/12/91 (A/MD), was isolated from the bronchial secretions of a 27-year-old animal caretaker. He had been admitted to the hospital with bilateral pneumonia and died of acute respiratory distress syndrome 13 days later. Antigenic analyses with postinfection ferret antisera and monoclonal antibodies to recent H1 swine hemagglutinins indicated that the hemagglutinin of this virus was antigenically rela... Antibodies to Human Influenzavirus Neuraminidase (the A-Asian-57 H2N2 Strain) in Sera from Australian Pelagic Birds Show Full Record 1457

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 Analysis of a Recently Isolated H1N1 Swine Influenza Virus Show Full Record 787

Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Genetics Immunology Influenza A Virus Influenza A Virus, H1N1 Subtype Metabolism Microbiology Pathology Swine Veterinary medicine Viral antigens Viral genes Abstract: From abstract (online abstract only): Hemagglutinins (HA) of H1N1 swine influenza viruses isolated in the United States have remained antigenically and genetically conserved for many years. In contrast to such conservation, the HA of A/Swine/Nebraska/1/92 (Sw/Neb) could readily be distinguished from those of contemporary porcine viruses. Twenty-eight amino acid mutations differentiated the HA of Sw/Neb and A/Swine/Indiana/1726/88, the most recent H1N1 swine influenza virus for which HA sequence ...
Antigenic and Genetic Characterization of a Novel Hemagglutinin Subtype of Influenza A Viruses from Gulls Show Full Record 812

Resource Type(s): Journal (Articles) Searchable Keywords: Avian influenza Birds Immunology Mammals Microbiology Viral Viral hemagglutinins Viruses Abstract: FREE FULL-TEXT AVAILABLE: Influenza A virus isolates from ring-billed, Franklin, blackback, and herring gulls in the United States possess a hemagglutinin (HA) distinct from the 12 reference HA subtypes. Serological assays (hemagglutination inhibition and double-immunodiffusion) with specific antisera to reference strains and to a representative gull isolate showed that the HA of the gull virus was not antigenically related to that of any known subtype. The gull virus did not replicate in ducks ... |
