Characterization of avian adenovirus type-4 causing hydro-pericardium syndrome in broilers in Karachi, Pakistan

Avian adenovirus was isolated from naturally infected birds during 1990 to 2003 in the vicinity ofKarachi, Pakistan. The virus is known to cause hydro-pericardium syndrome (HPS) in poultry. The mortalitywas recorded 20-50% in commercial broilers. Fifty field samples were collected; however, six samples wereselected for molecular studies.
