Characterization of a novel influenza A virus hemagglutinin subtype (H16) obtained from black-headed gulls.
In wild aquatic birds and poultry around the world, influenza A viruses carrying 15 antigenic subtypes of hemagglutinin (HA) and 9 antigenic subtypes of neuraminidase (NA) have been described. Here we describe a previously unidentified antigenic subtype of HA (H16), detected in viruses circulating in black-headed gulls in Sweden. In agreement with established criteria for the definition of anti...
متن کاملEpidemiology of Influenza A Virus among Black-headed Gulls, the Netherlands, 2006–2010
We sampled 7,511 black-headed gulls for influenza virus in the Netherlands during 2006-2010 and found that subtypes H13 and H16 caused annual epidemics in fledglings on colony sites. Our findings validate targeted surveillance of wild waterbirds and clarify underlying factors for influenza virus emergence in other species.
متن کاملHost Restrictions of Avian Influenza Viruses: In Silico Analysis of H13 and H16 Specific Signatures in the Internal Proteins
Gulls are the primary hosts of H13 and H16 avian influenza viruses (AIVs). The molecular basis for this host restriction is only partially understood. In this study, amino acid sequences from Eurasian gull H13 and H16 AIVs and Eurasian AIVs (non H13 and H16) were compared to determine if specific signatures are present only in the internal proteins of H13 and H16 AIVs, using a bioinformatics ap...
متن کاملInfluenza A virus surveillance in wild birds
Surveillance studies in wild animals provide information on the prevalence of avian influenza viruses in the environment, and enables banking of reference reagents and putative vaccine strains to be used in times of outbreaks in humans and animals. In the past five years we have performed surveillance studies in wild birds primarily in The Netherlands and Sweden. In ducks, geese and gulls the p...
