Characterisation of influenza a viruses isolated from turkeys in england during March-May 1979. Abstract Text:

During the early spring of 1979 turkeys on at least twelve sites in England became infected with influenza A viruses. On five of these sites no virus was isolated but birds were shown to have antibodies to Havl (four sites) and Hav2 antigenic subtypes of influenza A viruses. The eight viruses isolated were typed: A/turkey/England/192-328/79 (Havl Nav2/3), A/turkey/England/192-329/79 (Hav1 N2), A/turkey/England/199/79 (Hav1 Neq1), A/turkey/ England/214/79 (Hav1 Neq1), A/turkey/England/250/79 (Hsw1 N1), A/turkey/England/262/79 (Hav1 Nav2/3), A/turkey/England/272/79 (Havl Neq1), A/turkey/England/384/79 (Hav2 Nav4). Pathogenicity index tests in 6-week-old chickens agreed with the clinical signs seen in turkeys in the field. Three of the isolates: 199, 214 and 272 were of extremely high virulence, 384 showed intermediate virulence, while the other isolates were of low virulence.
