Abstract: A Newcastle disease virus(NDV) was isolated from duck in Guangdong. It was identified with hemagglutination,hemagglutination inhibition. These results showed the isolate had hemagglutination and was inhibited by the standard antibody of AIV-H5,AIV-H7,AIV-H9 and EDSV. It was amplified by RT-PCR and sequenced,which was used by the specific identification primers of NDV F gene. Thus,the isolate was identified as a duck NDV,named NDV/DUCK/SD/2006. In this research,the isolate were conducted virulence determination. Results showed that,the MDT,and IVPI of the isolate were 51.75 h,2.44 respectively,suggesting it was a velogenic strain.
