The detection of fowl adenovirus in chickens with hydropericardium syndrome in Isfahan and Charmahal-Va-Bakhtiyari provinces, Iran

Abstract

The hydropericardium in chickens is most common in Isfahan and Chcharmahal-va-Bakhtiyari, Iran. For this, the study was achieved for investigation of adenovirus role in induction of hydropericardium in these regions. In this study, 20 broiler flocks suspected to hydropericardium were sampled from hydropericardium fluid. Then, DNA was extracted and amplified by specific primers. The amplified fragment for detection of AV was 896 bp. The results showed that 10 in 20 flocks, and 47 in 200 samples were positive to AV. The results revealed that most of infected flocks were more than 30 days old. In this study, the correlation between infectivity to adenovirus and husbandry system were not significant. The infectivity rate in Isfahan and Chaharmahal-va-Bakhtiyari was not significant. Therefore, in addition to high altitude, adenovirus infection can play a role in increasing the prevalence of hydropericardium in these areas.
