Avian influenza (H5N1) virus in waterfowl and chickens, central China

Emerg Infect Dis. 2007 May;13(5):772-5. doi: 10.3201/eid1305.061209.

Abstract

In 2004, 3 and 4 strains of avian influenza virus (subtype H5N1) were isolated from waterfowl and chickens, respectively, in central People's Republic of China. Viral replication and pathogenicity were evaluated in chickens, quails, pigeons, and mice. We analyzed the sequences of the hemagglutinin and neuraminidase genes of the isolates and found broad diversity among them.
