| novel siadenovirus infection in a cockatiel with chronic liver disease. | 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 ... | 2019 | 30711577 |
| stress factors can reverse the pinealostimulatory effect of 6-hydroxydopamine on the pineal gland of blossomheaded parakeet (psittacula cyanocephala). | | 1982 | 6214967 |
| siadenovirus infection in two psittacine bird species. | consensus polymerase chain reaction was used to identify a novel adenovirus from two psittacine birds: a plum-headed parakeet (psittacula cyanocephala) with lethargy, weight loss, and marked leukocytosis; and an umbrella cockatoo (cacatua alba) with lethargy, weight loss, and feather abnormalities. phylogenetic and comparative sequence analysis suggested that this virus is a member of the genus siadenovirus, and is here termed psittacine adenovirus 2. this extends the characterized adenoviruses ... | 2009 | 19937528 |
| [polyostotic hyperostosis in a plum-headed parakeet (psittacula cyanocephala l., 1766]. | with emphasis on a case report, the clinical and pathological findings commonly associated with polyostotic hyperostosis as well as its etiology are discussed, and the available literature is reviewed. the diagnostic specifics of the disease are detailed, and a survey of possible differential diagnoses is given. | 1996 | 8720953 |
| a comparative study of annual changes in the pineal gland morphology with reference to the influence of melatonin on testicular activity in tropical birds, psittacula cyanocephala and ploceus philippinus. | the aim of the present comparative investigation was to examine annual pineal cytological changes and the action of melatonin in relation to testicular activity in two wild tropical avian species. the findings revealed that in both blossomheaded parakeets (psittacula cyanocephala) and indian weaver birds (ploceus philippinus) the pineal gland was inactive, with reduced karyometric values during the breeding season. a pinealoactive phase showing significantly increased pinealocyte nuclear diamete ... | 1993 | 8262358 |
