Surveillance of influenza virus B circulation in Northern Italy: summer-fall 2008 isolation of three strains and phylogenetic analysis.
نویسندگان
چکیده
Influenza virus type B strains were unexpectedly detected and isolated in Italy during summer-fall 2008 from three patients travelling to Italy from Lebanon, Senegal and Uzbekistan. The three summer-fall strains matched to a high degree the hemagglutinin (HA1) of influenza virus type B strains circulating in Italy in the second part (January through April) of the 2007/2008 season, and HA1 of the type B strains included in the 2008/2009 vaccine (B/Yamagata/16/88 lineage). Surveillance of influenza virus circulation in Western countries also during the summer-fall season may help to trace and anticipate the appearance of new influenza virus variants.

Background: Influenza virus is a major infectious pathogen of the respiratory system causing a high degree of morbidity and mortality annually. The worldwide vaccines are decided and produced annually by World Health Organization and licensed companies based on the samples collected from all over the world. The aim of this study was to determine phylogenecity and heterogenecity of the circulati...
متن کاملMolecular characterization and phylogenetic analysis of human influenza A viruses in three consecutive seasons with different epidemiological profiles.
INTRODUCTION Influenza activity and influenza virus circulation were observed in Lombardy (northern Italy) during three consecutive seasons and the molecular characteristics of circulating viruses analysed to control for introduction of new variants. METHODS The molecular characterization of 38 isolates, namely 20 A/H3N2 and 18 A/H1N1 influenza strains from the 2005/06, 2006/07 and 2007/08 se...
متن کاملSequence Analysis and Phylogenetic Profiling of the Nonstructural (NS) Genes of H9N2 Influenza A Viruses Isolated in Iran during 1998-2007
The earliest evidences on circulation of Avian Influenza (AI) virus on the Iranian poultry farms date back to 1998. Great economic losses through dramatic drop in egg production and high mortality rates are characteristically attributed to H9N2 AI virus. In the present work non-structural (NS) genes of 10 Iranian H9N2 chicken AI viruses collected during 1998-2007 were fully sequenced and subjec...
متن کاملOn Temporal Patterns and Circulation of Influenza Virus Strains in Taiwan, 2008-2014: Implications of 2009 pH1N1 Pandemic
BACKGROUND It has been observed that, historically, strains of pandemic influenza led to succeeding seasonal waves, albeit with decidedly different patterns. Recent studies suggest that the 2009 A(H1N1)pdm09 pandemic has had an impact on the circulation patterns of seasonal influenza strains in the post-pandemic years. In this work we aim to investigate this issue and also to compare the relati...
متن کاملFifteen years of epidemiologic, virologic and syndromic influenza surveillance: A focus on type B virus and the effects of vaccine mismatch in Liguria region, Italy
In order to estimate the burden of influenza and to describe the genetic evolutionary pattern and antigenic variability of type B viral strains, data deriving from 3 surveillance systems active in Liguria region, Northern Italy, were described. Since the re-emergence of the Victoria lineage in 2001, the clinical-epidemiological and syndromic surveillances demonstrated the heavy burden of influe...
