Abstract   

Backyard chickens play an important role in the epidemiology of H9N2 avian influenza virus infection. Close contact of backyard chickens with migratory birds, especially with aquatic birds, as well as neighboring poultry farms, may pose the risk of transmitting avian influenza virus, but little is known about the disease status of backyard poultry. A H9N2 avian influenza virus seroprevalence survey was carried out in 500 backyard chickens from villages around Maharlou lake in Iran, using the hemagglutination-inhibition (HI) test. The studied backyard chickens had not been previously vaccinated and showed no clinical signs of disease. The overall HI titer and seroprevalence against H9N2 were 7.73 and 81.6%, respectively.

Key words: Backyard chickens; H9N2; Iran; Maharlou lake; Seroprevalence
