Abstract:

Budgerigar is a common name for a colorful Australian native bird belonging to the Melopsittacus undulatus species. It is a very familiar pet around the world and its breeding has been grown in Iran. This study was conducted on a 2-year-old budgerigar with a nodular mass on the left wing. Physical examination revealed a firm, round and well-circumscribed mass approximately 1.70 cm in diameter. Radiographs showed a soft tissue mass with no involvement of bony structures. Fine needle aspiration was performed and the sample was cultured. In cultural examination, Klebsiella spp. were isolated in pure culture. Genus and species of the bacteria were confirmed using multiplex polymerase chain reaction. The mass was surgically excised and it was mainly composed of numerous, large lipid-laden macrophages containing abundant vacuolated cytoplasm, extracellular acicular cholesterol clefts and large number of multinucleated giant cells (especially multinucleated Touton giant cells) in the dermis. Finally, a diagnosis of cutaneous xanthogranuloma was made based on histopathological findings.

A rare case of cutaneous leiomyosarcoma in budgerigar (Melopsittacus undulatus)

  Leiomyosarcoma in birds is relatively rare. This tumor as a muscle neoplasm was reported in captive and free ranging birds. Smooth muscle cells may develop to the leiomyosracoma, but splenic smooth muscle trabeculae is most common site of the tumor growth. Although budgerigars have an incidence of neoplastic diseases but smooth muscle tumors were rarely reported in this species. To the best o...

Lymphoid Leucosis and Coligranoluma in a Budgerigar (Melopsittacus undulatus)

An adult female budgerigar (Melopsittacus undulatus) presented with abdominal enlargement. The condition of the bird deteriorated after needle aspiration for cytological examination. The budgerigar was euthanatized and a complete necropsy was performed. Microscopic sections were prepared and stained with hematoxylin and eosin, Gram staining, periodic acid-Schiff (PAS) and acid-fast staining. Es...

Intrahepatic cholangiocarcinoma and encephalomalacia in a budgerigar (Melopsittacus undulatus)

Encephalomalacia is softening or loss of brain tissue following cerebral infarction; cerebral ischemia infection, craniocerebral trauma or other injuries. Cholangiocarcinomas are malignant neoplasms of biliary epithelium, which usually arise from the intrahepatic ducts. A budgerigar was presented with a history of ataxia, decreased activity, neck weakness and weight loss. Supportive care was at...

The Nutrition of the Budgerigar (Melopsittacus undulatus)1

Growing interest in the nutrition of the budgerigar (Melopsittacus undulatus) has highlighted the paucity of knowledge in this area. The aims of this study were to review the available literature on their individual nutrient requirements and relate this to the nutrient content of their predominantly seed-based diet and to investigate the effect of the bird's daily energy requirement on the fluc...

Temporal integration of acoustic signals by the budgerigar (Melopsittacus undulatus).

Avoidance conditioning and a modified method of limits psychophysical procedure were used to study temporal integration of tone and noise signals in the budgerigar (Melopsittacus undulatus). Integration of both tone and noise signals can be described by a negative exponential function with a time constant of about 200 ms. At very short durations there were differences in the integration of tone...
