title: Studies on the aetiology of hydropericardium syndrome (Angara disease) in broilers.
abstract: The study was carried out to determine the aetiological agent(s) associated with hydropericardium syndrome (Angara disease) in broilers in Pakistan. The results indicate that in addition to adenovirus some other agent is involved in causing the disease but that this agent requires co-infection by an adenovirus for the reproduction of the typical signs of the syndrome. The nature of this agent remains unknown because no discrete virus or virus-like particle could be seen by electron microscopy.
