Antibodies to human influenzavirus neuraminidase (the A-Asian-57 H2N2 strain) in sera from Australian pelagic birds.

摘要: Sera collected from Australian pelagic birds specifically inhibited the neuraminidase of Asian/57 (H2N2) strain human influenzavirus. Neuraminidase inhibition titres some sera were high and avidity inhibitor was comparable to that specific antibody. The A/Hong Kong/1/68 (H3N2), which has undergone considerable antigenic drift in man since 1957, a lesser extent by bird sera, while neuraminidases A/BEL/42 (H0N1) A/FM/1/47 (H1N1) strains not at all. could be removed adsorption with A/57 virus particles, but particles A/BEL or A/FM1 viruses. These results suggested antibodies found wedge-tailed shearwaters (Puffinus pacificus) noddy terns (Anous minutus) nesting on islands off north-east coast Australia. They bridled (Sterna anaetheta) brown gannets (Sula leucogaster) same islands. Antibodies also detected short-tailed tenuirostris), migrate around Pacific Ocean, suggesting these may responsible for bringing avian influenzaviruses areas Northern Hemisphere into coastal waters.
