detection of retrovirus sequences in budgerigars with tumours.	renal tumours are a common neoplastic disease of budgerigars. although a retro-virus has been implicated as the aetiological agent, there is no definitive proof for this hypothesis. sixteen birds suspected to have renal tumours were examined in an attempt to elucidate the possible role of retroviruses. thirteen birds had renal tumours and the majority of these birds showed abdominal enlargement and paresis. renal masses were detected by radiography in nine birds. post-mortem examination confirme ...	1993	18670995
neoplasms in budgerigars (melopsittacus undulatus): clinical, pathomorphological and serological findings with special consideration of kidney tumours.	according to findings of others and to our own investigations, kidney tumours represent a remarkably high proportion of all tumours in budgerigars. therefore, 74 budgerigars, clinically suspicious for abdominal tumours, were analysed individually by monitoring clinical signs, gross lesions, histology, the expression of the group-specific (gs) antigen of avian leukosis virus (alv), the expression of immunoglobulins m and g, and the distribution of age and tumour incidence. lameness and abdominal ...	1983	18766792
natural unusual myeloblastosis in a budgerigar (melopsittacus undulatus): histopathologic diagnosis.	the subgroup j avian leukosis virus favors the myelocytic series cells and causes myeloid leukosis (myeloblastosis and myelocytomatosis). natural cases of myeloblastosis (myeloblastic myeloid leukosis) are uncommon and usually occur in adult chickens. this paper describes clinical signs and gross and histopathologic features of myeloblastosis in an adult female budgerigar (melopsittacus undulatus) that was infected naturally. at necropsy, the spleen was greatly enlarged (enlarged seven or eight ...	2016	26953949
