Plain-English summary
A 4-year-old female cockatiel was found to have listeriosis, a serious bacterial infection, after showing signs like being fluffed up, weakness, and weight loss over several days. Unfortunately, despite the diagnosis, the bird passed away. The examination revealed significant inflammation and the presence of Listeria monocytogenes bacteria in various organs, including the liver and spleen. This case highlights the importance of recognizing symptoms early, as listeriosis can be severe in birds.

Abstract
Listeriosis was diagnosed in a 4-yr-old female cockatiel (Nymphicus hollandicus) that died after exhibiting clinical signs that included a fluffed-up appearance, weakness, and loss of weight of several days duration. Grossly, the bird was moderately emaciated, and the liver and spleen were enlarged. Microscopically, there was mild-to-moderate inflammation associated with rod-shaped, gram-positive bacteria in the liver, spleen, kidneys, adrenal glands, bone marrow, and esophagus. Listeria monocytogenes was isolated from the liver, trachea, and intestine. The isolate was identified as type 1 by agglutination with specific antisera, and it further identified as belonging to serovar group 1/2a, 3a by multiplex polymerase chain reaction assay. Listeria monocytogenes also was detected in affected tissues by immunohistochemistry.
