Phylogenetic Analysis of the Hemagglutinin Genes of Twenty-Six Avian Influenza Viruses of Subtype H9N2 Isolated from Chickens in China During 1996–2001
1 Jan 2003
Abstract excerpt
The complete coding region of hemagglutinin genes from 26 influenza A viruses of H9N2 subtype isolated from chicken flocks in China during 1996-2001 was amplified and sequenced. Sequence analysis and phylogenetic studies of H9N2 subtype viruses on the basis of data of 26 viruses in this study and 71 selected strains available in the GenBank were conducted. The results revealed that all the mainland China isolates...
