Abstract: The virus was isolated from one flock chicken which might be infected H9 subtype avian influenza virus, which could agglutinate the red blood cell of chicken. The pathogen was identified as H9 subtype avian influenza virus by HI test, Neutralization test of chicken embryo and RT-PCR, and it was named CH02 strains. The HA titer was 27.67±0.58; the hemagglutination feature could be inhibited by the standard positive serums which against avian influenza virus H9 subtype, and the HI titer was 7log2;50% egg infectious dose of the purified virus was 10-8.68/0.1 mL;the mean death time of the minimum lethal
