Detection of Antibodies Against Avian Influenza Virus in Wild Pigeons and Starlings

Sixty wild birds for each of pigeons and starlings were captured in Mosul and examined clinically and serologically for avian influenza virus (AIV) infection. ELISA and haemagglutination inhibition (HI) tests were used for the detection of (AIV) antibodies in both types of examined birds. Clinically the pigeons appeared dull with loss of appetite. The percentage of positive serum antibodies titers against (AIV) was 81.8 and 50% with ELISA and HI tests, respectivly. The starlings did not show any abnormal clinical signs and all serum samples showed negative results by ELISA and HI tests. In conclusion, pigeons only showed ability to be infected with AIV subtype H9N2 and they may play an important role in spreading (AIV) as natural carriers.
