چکیده مقاله:
Bird flu is one of the most critical and dangerous viral diseases that have been reported all over the world. Although H۹N۲ viruses are considered a threat by themselves, they are known to be very zoonotic as donors of gene segments to other viruses, so to prevent the emergence of new zoonotic viruses, better control of viruses should be done and H۹N۲ should be noted. The current cross-sectional study was conducted from March ۲۰۱۷ to June ۲۰۱۸. In total, ۴۸۰ birds, including ۲۲۲ chickens and roosters, ۸۴ turkeys, ۱۲۰ ducks, and ۵۴ pigeons, were randomly sampled from ۱۶ villages. Then, the ELISA screening test was performed first, followed by the HA and HI tests. Out of the ۴۸۰ samples collected, ۴۶۱ (۹۶.۰۴%) were positive for ELISA and ۴۵۱ (۹۳.۹۵%) were positive for serum titers. Since the H۹N۲ influenza viruses are not acute viruses and the conflict with them does not lead to the bird's death, much effort is not made to eradicate them. This issue leads to the widespread circulation of this virus in poultry flocks. It is especially endemic to poultry and gives this group of viruses a chance to become acute viruses due to the accumulation of point mutations. It is considering that there is no extermination policy regarding H۹N۲ influenza in Iran. Effective vaccines can reduce the infection of local and rural poultry with this virus.
