The first outbreak of low pathogenic avian influenza (LPAI), H9N2 virus subtype, in 1996 prompted an eradication response, but LPAI returned to Korea in 1999. The relationship between the first and the recurrent viruses is unclear. To determine the molecular epizootiology of recurrent LPAI, we performed phylogenetic analysis with partial nucleotide sequences of four gene segments (HA, NA, NP and PB2) from eight chicken-origin H9N2 viruses. The recurrent H9N2 viruses showed higher nucleotide… CONTINUE READING
