This report describes a case of proventricular rupture associated with Psittaciforme 1 Bornavirus in a 10-year old Major Mitchell Cockatoo (Lophochroa leadbeateri) who presented with a 2-day history of weakness and weight loss. On necropsy, a fibrinonecrotizing coelomitis and an enlarged proventriculus with a 0.5 cm in diameter transmural perforation characterized the main findings. Histology confirmed the locally extensive, transmural necrotizing proventriculitis with coelomitis. Additionally, lymphoplasmacytic ganglioneuritis in the proventriculus, heart, small intestine, and adrenal gland, as well as lymphoplasmacytic encephalitis, hallmarks of proventricular dilatation disease. Psittaciform 1 bornavirus RNA was confirmed in the brain, proventriculus and ventriculus by RT-PCR. Avian Bornavirus antigen was identified by immunohistochemistry in the brain and heart.
