Abstract
An outbreak of severe acute respiratory disease characterized by tracheitis and bronchitis was observed in young goslings on a large-scale goose farm in Hungary. Histological examination revealed amphophilic intranuclear inclusion bodies in the superficial epithelial cells of the trachea and bronchi. Adenovirus-like particles were detected by electron microscopy, and the virus isolated from the trachea and the lungs was identified as egg drop syndrome (EDS) virus by serological and genomic examination. The clinical and pathological signs were reproduced by intratracheal administration of the virus isolate to 1-day-old goslings free of EDS antibodies. The presence of EDS virus DNA in different organs of the naturally and experimentally infected goslings was detected by polymerase chain reaction. This is the first report on the involvement of EDS virus in severe respiratory disease of geese.
