Abstract
BACKGROUND: Influenza virus is one of the major viral respiratory pathogens infecting human beings. OBJECTIVES: To determine the influenza A virus variants responsible for the 2006-2007 epidemic season in Corsica Island, France. STUDY DESIGN: Of 134 nasal samples of adult patients tested by culture and RT-PCR assays, 85 influenza A strains were identified; 81 (95%) were sub-typed as A/H3N2 and 4 (5%) were sub-typed as A/H1N1. RESULTS: All of the HA sequences of the A/H3N2 viruses circulating in Corsica Island appeared to be closely related to the A/Wisconsin/67/2005 vaccine strain and segregated into two sub-groups that were genetically distinct from other viruses circulating in other countries during 2006/2007. One of these sub-groups was distinguished by the substitution H156Q whereas the second demonstrated at least one of the 3 other additional mutations (R142G, L157S and K173E) common to the HA1 sequence of A/Nepal/921/2006 reference strain. Among the 14 strains of this second sub-group, 10 viral strains had been isolated from vaccinated adult patients. CONCLUSION: These findings suggest that a prospective analysis of the HA sequences of influenza isolates may allow an early detection of newly evolved variants with potential epidemiological inference.

RESULTS: All of the HA sequences of the A/H3N2 viruses circulating in Corsica Island appeared to be closely related to the A/Wisconsin/67/2005 vaccine strain and segregated into two sub-groups that were genetically distinct from other viruses circulating in other countries during 2006/2007. One of these sub-groups was distinguished by the substitution H156Q whereas the second demonstrated at least one of the 3 other additional mutations (R142G, L157S and K173E) common to the HA1 sequence of A/Nepal/921/2006 reference strain. Among the 14 strains of this second sub-group, 10 viral strains had been isolated from vaccinated adult patients. CONCLUSION: These findings suggest that a prospective analysis of the HA sequences of influenza isolates may allow an early detection of newly evolved variants with potential epidemiological inference.</p> </div></front></TEI><hal api="V3"> <titleStmt> <title xml:lang="en">Co-circulation of two genetically distinct sub-groups of A/H3N2 influenza strains during the 2006-2007 epidemic season in Corsica Island, France.</title> <author role="aut"> <persName> <forename type="first">Alessandra</forename> <surname>Falchi</surname> </persName> <idno type="halauthorid">647168</idno> <affiliation ref="#struct-3065"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Laurent</forename> <surname>Varesi</surname> </persName> <idno type="halauthorid">647186</idno> <affiliation ref="#struct-843"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Christophe</forename> <surname>Arena</surname> </persName> <idno type="halauthorid">647170</idno> <affiliation ref="#struct-3065"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Nicolas</forename> <surname>Leveque</surname> </persName> <idno type="halauthorid">647210</idno> <affiliation ref="#struct-7569"></affiliation> <affiliation ref="#struct-202715"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Fanny</forename> <surname>Renois</surname> </persName> <idno type="halauthorid">647211</idno> <affiliation ref="#struct-7569"></affiliation> <affiliation ref="#struct-202715"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Thierry</forename> <surname>Blanchon</surname> </persName> <idno type="halauthorid">209496</idno> <affiliation ref="#struct-3065"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Jean Pierre</forename> <surname>Amoros</surname> </persName> <idno type="halauthorid">647169</idno> <affiliation ref="#struct-3065"></affiliation> </author> <author role="aut"> <persName> <forename type="first">Laurent</forename> <surname>Andreoletti</surname> </persName> <idno type="halauthorid">647172</idno> <affiliation ref="#struct-7569"></affiliation> <affiliation ref="#struct-202715"></affiliation> </author> <editor role="depositor"> <persName> <forename>Laurent</forename> <surname>Varesi</surname> </persName> <email type="md5">74b1a662ede18074441b5d1f082c9171</email> <email type="domain">univ-corse.fr</email> </editor> </titleStmt> <editionStmt> <edition n="v1" type="current"> <date type="whenSubmitted">2011-10-03 13:36:20</date> <date type="whenModified">2019-02-07 15:46:34</date> <date type="whenReleased">2011-10-03 13:36:20</date> <date type="whenProduced">2009-07</date> </edition> <respStmt> <resp>contributor</resp> <name key="165471"> <persName> <forename>Laurent</forename> <surname>Varesi</surname> </persName> <email type="md5">74b1a662ede18074441b5d1f082c9171</email> <email type="domain">univ-corse.fr</email> </name> </respStmt> </editionStmt> <publicationStmt> <distributor>CCSD</distributor> <idno type="halId">hal-00628455</idno> <idno type="halUri">https://hal.archives-ouvertes.fr/hal-00628455</idno> <idno type="halBibtex">falchi:hal-00628455</idno> <idno type="halRefHtml">J Clin Virol, 2009, 45 (3), pp.265-8. ⟨10.1016/j.jcv.2009.05.004⟩</idno> <idno type="halRef">J Clin Virol, 2009, 45 (3), pp.265-8. ⟨10.1016/j.jcv.2009.05.004⟩</idno> </publicationStmt> <seriesStmt> <idno type="stamp" n="UPMC" corresp="SORBONNE-UNIVERSITE">Université Pierre et Marie Curie</idno> <idno type="stamp" n="CNRS">CNRS -

OBJECTIVES: To determine the influenza A virus variants responsible for the 2006-2007 epidemic season in Corsica Island, France. STUDY DESIGN: Of 134 nasal samples of adult patients tested by culture and RT-PCR assays, 85 influenza A strains were identified; 81 (95%) were sub-typed as A/H3N2 and 4 (5%) were sub-typed as A/H1N1. RESULTS: All of the HA sequences of the A/H3N2 viruses circulating in Corsica Island appeared to be closely related to the A/Wisconsin/67/2005 vaccine strain and segregated into two sub-groups that were genetically distinct from other viruses circulating in other countries during 2006/2007. One of these sub-groups was distinguished by the substitution H156Q whereas the second demonstrated at least one of the 3 other additional mutations (R142G, L157S and K173E) common to the HA1 sequence of A/Nepal/921/2006 reference strain. Among the 14 strains of this second sub-group, 10 viral strains had been isolated from vaccinated adult patients. CONCLUSION: These findings suggest that a prospective analysis of the HA sequences of influenza isolates may allow an early detection of newly evolved variants with potential epidemiological inference.</p> </abstract> </profileDesc> </hal></record>Pour manipuler ce document sous Unix (Dilib)
