Plain-English summary
A 15-year-old female cockatiel was being treated for chronic liver disease when she sadly passed away. A thorough examination revealed severe liver damage and the presence of a new virus called siadenovirus, which is known to affect birds. This virus was found alongside the liver issues, suggesting it may have contributed to her health problems. Unfortunately, despite ongoing management for her liver condition, the cockatiel did not survive.

Abstract
A 15-year-old female cockatiel (Nymphicus hollandicus) undergoing long term management for hepatopathy died and underwent necropsy. Microscopic findings were consistent with chronic liver disease characterized by distorted hepatic architecture, fibrosis and biliary proliferation. The additional finding of large intranuclear inclusion bodies within hepatocytes and renal tubular epithelium prompted diagnostic next generation sequencing. The assembled sequences isolated from pooled kidney and liver were related to siadenoviruses. The genus Siadenovirus, within the family Adenoviridae, includes several species of viruses that pathogenically infect avian species including hemorrhagic enteritis virus of turkeys and marble spleen virus of pheasants. Siadenoviruses have previously been reported in seven psittacine species: a plum-headed parakeet (Psittacula cyanocephala), an umbrella cockatoo (Cacatua alba) budgerigars (Melopsittacus undulates), an eastern rosella (Platycercus eximius), a scarlet chested parrot (Neophema splendida), a cockatiel (Nymphicus hollandicus), and a red-crowned parakeet (Cyanoramphus novaezelandiae). This report describes a novel siadenovirus in a cockatiel that is highly identical to budgerigar adenovirus 1 and distinct from PsAdV-2 in cockatiels. We report the clinical pathologic, gross, and histopathologic findings in a cockatiel with chronic hepatitis and a novel siadenovirus, PsAdV-5. The sequencing data is presented with a phylogenetic analysis.
