[ 1 ] - Phylogenetic analysis of PB2 gene of H9N2 subtype of avian influenza viruses isolated from commercial chickens in Tehran province of Iran during 1998-2001

The PB2 protein of influenza A viruses has been shown as host range determinant. In this study PB2gene of five H9N2 isolates from Tehran province during the period of 1998-2001 were partially amplifiedand sequenced to do phylogenetic study. Iranian isolates could be classified in Eurasian lineage according totheir PB2 gene sequences. The PB2 genes of these isolates are different from those of M...
