Abstract
Fowl adenovirus (FAdVs) infections have an important economic impact, especially in the production of broilers. It is considered the main cause of three syndromes: inclusion body hepatitis, hepatitis-hydropericardium syndrome, and gizzard erosions and ulcerations. This study was conducted on three broiler farms with total bird numbers ranging from 16,500 to 25,000 and ages 26-32 days in Sharkia province, Egypt. Chickens were vaccinated with commercially available Newcastle disease virus (NDV), infectious bronchitis virus (IBV), avian influenza virus (AIV), and infectious bursal disease virus (IBDV) vaccines. The birds showed clinical signs mainly depression, greenish diarrhea, and respiratory signs with mortalities. The pathological lesions were commonly hemorrhages on livers, papillae of proventriculus, and cecal tonsils, hydropericardium, gizzard erosion, and atrophied bursa of fabricius. Based on the molecular diagnosis using real-time machine and primers specific to FAdVs (conserved to all species A-E), and virulent NDV (vNDV), the three broiler flocks were positive for both viruses. The results of the examination and diagnosis of three broiler farms indicated the presence of FAdV infection, accompanying the infection with the most prevalent and circulating viral agent, NDV.
