Pacheco's disease (PD) is a highly contagious, acute disease of psittacines caused by a herpesvirus. Five 56-day-old dead parakeets (Neophema bourkii) were submitted to the National. Veterinary Research & Quarantine Service for diagnosis. At necropsy, principle lesions were seen in the pancreas, which were hard, whitish, nodular and atrophic resulting in distortion of the duodenal loop. Histologically, lymphocytic pancreatitis with eosinophilic intranuclear inclusions syncytium-formed acinar epithelium was prominent. In the brain, marked focal gliosis and perivascular lymphocytic cuffing were observed. On the electron microscopy examination, various forms of viral particles were found in both the nucleus and cytoplasm of acinar epithelium of pancreas, identified as a herpesvirus. These results were suggested that the cases were diagnosed as PD in the parrakeet.
