title: Reassortant Avian Influenza A(H9N2) viruses in chickens in retail poultry shops, Pakistan, 2009-2010.
abstract: Phylogenetic analysis of influenza viruses collected during December 2009-February 2010 from chickens in live poultry retail shops in Lahore, Pakistan, showed influenza A(H9N2) lineage polymerase and nonstructural genes generate through inter- and intrasubtypic reassortments. Many amino acid signatures observed were characteristic of human isolates; hence, their circulation could enhance inter- or intrasubtypic reassortment.
