  • We sampled wild birds for the Avian Influenza Virus (AIV)(H5, H7 and H9) survey in the AI infected regions of Guangdong during its eruptive period in early 2004. Seventy-six samples of blood serum, 125 swab samples and 21 organic samples were collected. The method of agar gel precipitation (AGP) and hemagglutination inhibitory (HI) was adopted in serum detection. The chicken embryo culture was adopted in virus detection. Our results showed: (1) H9 viruses were only found in starlings of Nan'ao, Shantou,in the AI noninfected regions.(2) 31.6% H5 and 23.7% H9 immunoreactive blood serums were detected in Leizhou, Luoding, Haifeng and Shantou. The positive rates of wild birds in inshore area are higher than in other regions. (3) The positive rate of migratory birds is higher than resident birds. Therefore, we concluded that migratory birds would spread AIV in its eruptive period.

Preliminary Investigation of Avian Influenza in Wild Birds in the Highly Pathogenic Avian Influenza Infected Regions of Guangdong in Early 2004

Abstract: We sampled wild birds for the Avian Influenza Virus (AIV)(H5, H7 and H9) survey in the AI infected regions of Guangdong during its eruptive period in early 2004. Seventy-six samples of blood serum, 125 swab samples and 21 organic samples were collected. The method of agar gel precipitation (AGP) and hemagglutination inhibitory (HI) was adopted in serum detection. The chicken embryo culture was adopted in virus detection. Our results showed: (1) H9 viruses were only found in starlings of Nan'ao, Shantou,in the AI noninfected regions.(2) 31.6% H5 and 23.7% H9 immunoreactive blood serums were detected in Leizhou, Luoding, Haifeng and Shantou. The positive rates of wild birds in inshore area are higher than in other regions. (3) The positive rate of migratory birds is higher than resident birds. Therefore, we concluded that migratory birds would spread AIV in its eruptive period.
