Serological Evaluation for Supporting the Potential Role of House Sparrows in LPAIV (H9N2) Transmission

摘要

House sparrows (Passer domesticus) are abundant and widespread species of birds within the order Passeriformes and may contribute to AIV transmission and maintenance in nature. This study was carried out to find the role of house sparrows in the spread of low-pathogenicity avian influenza viruses as carrier birds. For this reason seroprevalence survey was carried out in two-hundred house sparrows, using the hemagglutination-inhibition (HI) test. The studied sparrows did not show any clinical signs of disease. The Overall HI titer and seroprevalence against H9N2 were 7.14 and 76%, respectively. Results of this study revealed that house sparrows showed ability to be infected with H9N2 avian influenza virus and play an important role in spreading of AIV as natural carriers.
