Abstract
Abstract: Genetic analysis indicated that the pandemic influenza strains derived from wild aquatic birds harbor viruses of 15 hemagglutinin (HA) and 9 neuraminidase (NA) antigenic subtypes. Surveillance studies have shown that H9N2 subtype viruses are worldwide in domestic poultry and could infect mammalian species, including humans. Here, we genetically analyzed the HA and NA genes of five H9N2 viruses isolated from the migratory ducks in Hokkaido, Japan, the flyway of migration from Siberia during 1997–2000. The results showed that HA and NA genes of these viruses belong to the same lineages, respectively. Compared with those of A/quail/Hong Kong/G1/97-like and A/duck/Hong Kong/Y280/97-like viruses, HA and NA of the migratory duck isolates had a close relationship with those of H9N2 viruses isolated from the chicken in Korea, indicating that the Korea H9N2 viruses might be derived from the migratory ducks. The NA genes of the five isolates were located in the same cluster as those of N2 viruses, which had caused a human pandemic in 1968, indicating that the NA genes of the previous pandemic strains are still circulating in waterfowl reservoirs. The present results further emphasize the importance of carrying out molecular epidemiological surveillance of H9N2 viruses in wild ducks to obtain more information for the future human influenza pandemics preparedness.

Compared with those of A/quail/Hong Kong/G1/97-like and A/duck/Hong Kong/Y280/97-like viruses, HA and NA of the migratory duck isolates had a close relationship with those of H9N2 viruses isolated from the chicken in Korea, indicating that the Korea H9N2 viruses might be derived from the migratory ducks. The NA genes of the five isolates were located in the same cluster as those of N2 viruses, which had caused a human pandemic in 1968, indicating that the NA genes of the previous pandemic strains are still circulating in waterfowl reservoirs. The present results further emphasize the importance of carrying out molecular epidemiological surveillance of H9N2 viruses in wild ducks to obtain more information for the future human influenza pandemics preparedness.</abstract><subject lang="en"><topic>H9N2</topic><topic>HA and NA</topic><topic>influenza virus</topic><topic>migratory ducks</topic><topic>phylogenetic analysis</topic></subject><relatedItem type="host"><titleInfo><title>Virus Genes</title></titleInfo><titleInfo type="abbreviated"><title>Virus Genes</title></titleInfo><genre type="journal" authority="ISTEX" authorityURI="https://publication-type.data.istex.fr" valueURI="https://publication-type.data.istex.fr/ark:/67375/JMC-0GLKJH51-B">journal</genre><originInfo><publisher>Springer</publisher><dateIssued encoding="w3cdtf">2003-12-01</dateIssued><copyrightDate encoding="w3cdtf">2003</copyrightDate></originInfo><subject><genre>Biomedicine</genre><topic>Medical Microbiology</topic><topic>Virology</topic><topic>Plant Sciences</topic></subject><identifier type="ISSN">0920-8569</identifier><identifier type="eISSN">1572-994X</identifier><identifier type="JournalID">11262</identifier><identifier type="IssueArticleCount">11</identifier><identifier type="VolumeIssueCount">3</identifier><part><date>2003</date><detail type="volume"><number>27</number><caption>vol.</caption></detail><detail type="issue"><number>3</number><caption>no.</caption></detail><extent unit="pages"><start>291</start><end>296</end></extent></part><recordInfo><recordOrigin>Kluwer Academic Publishers, 2003</recordOrigin></recordInfo></relatedItem><identifier type="istex">A2C3DFFE2C571D558095CA6C3C50E96449D0637A</identifier><identifier type="ark">ark:/67375/VQC-4ZCVMMNN-2</identifier><identifier type="DOI">10.1023/A:1026304117797</identifier><identifier type="ArticleID">5146772</identifier><identifier type="ArticleID">Art10</identifier><accessCondition type="use and reproduction" contentType="copyright">Kluwer Academic Publishers, 2003</accessCondition><recordInfo><recordContentSource authority="ISTEX" authorityURI="https://loaded-corpus.data.istex.fr" valueURI="https://loaded-corpus.data.istex.fr/ark:/67375/XBH-3XSW68JL-F">springer</recordContentSource><recordOrigin>Kluwer Academic Publishers, 2003</recordOrigin></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/ark:/67375/VQC-4ZCVMMNN-2/record.json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
