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...
متن کاملA 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...
متن کاملThe 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...
متن کاملIntrahepatic 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...
متن کاملTemporal 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...
