Hepatic intranuclear inclusion bodies in a cockatoo bird (Cacatua sulphurea).

One hundred and nineteen cockatoos (Cacatua sulphurea) were kept at the Animal Quarantine Station in Denpasar, Indonesia. These birds were intended to be exported overseas. Nine birds were found dead in a period of 17 days. Necropsies were performed on three, and tissues were taken for microbiological and histopathological examination. Examinations revealed that two birds had both Newcastle disease and aspergillosis, and one bird was found to contain hepatic intranuclear inclusion bodies suggestive of Pacheco's parrot disease. Newcastle disease and aspergillosis in cockatoos have frequently been diagnosed in our laboratory. However, the finding of hepatic intranuclear inclusion bodies in a cockatoo is considered to be the first in Indonesia.
