Imported Parakeets Harbor H9N2 Influenza A Viruses That Are Genetically Closely Related to Those Transmitted to Humans in Hong Kong

1 Apr 2001

Abstract excerpt

In 1997 and 1998, H9N2 influenza A viruses were isolated from the respiratory organs of Indian ring-necked parakeets (Psittacula Krameri manillensis) that had been imported from Pakistan to Japan. The two isolates were closely related to each other (>99% as determined by nucleotide analysis of eight RNA segments), indicating that H9N2 viruses of the same lineage were maintained in these birds for at least 1 year....
