خلاصه انگلیسی

Influenza is one of the most important infectious viral diseases of birds, which causes huge economic losses to the poultry industry of countries every year. In recent years, H5 and H7 subtypes of influenza viruses (high pathogenic avian influenza) have been detected in Iran. Backyard poultry can cause spread these viruses to industrial poultry as reservoirs and vectors. Therefore, the aim of this study was to survey seroprevalence of H5 and H7 subtypes of avian influenza viruses in rural domestic poultry of Ardabil province, northwest of Iran. This cross-sectional study was conducted from September to December of 2015. In this study, 943 blood serum samples were randomly collected from backyard poultry of 40 villages. The hemagglutination inhibition (HI) test was performed on the serum samples according to Iran Veterinary Organization (IVO) protocol to detect H5 and H7 subtypes of influenza virus. All the examined sera were negative for H5N1, H5N2, H7N1 and H7N7 subtypes of influenza virus. The results of this study show no seroprevalence of H5 and H7 subtypes of influenza virus in rural domestic poultry of Ardabil province. Active surveillance must be carried out in rural domestic poultry.
