Molecular Characterization of the early phase of the Novel influenza A H1N1(2009) Viruses
新甲型H1N1(2009)流感病毒的早期分子特征

Objective] Pathogens of the first influenza pandemic this century belong to influenza A H1N1 viruses,which are different from human seasonal H1N1 viruses in antigenic and genetic characterization. To better understand the genetic characteristics and evolution,timely detect variant strains with epidemiological importance,we analyzed in detail the molecular characterization of the early influenza A H1N1 (2009) virus. Method ] genomic sequences of reference influenza viruses were obtained from Influenza Reso...
