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 confirmed the presence of abdominal tumours which were mostly confined to the kidneys. All of the renal tumours were carcinomas. ELISA tests to detect the presence of p27 of avian leukosis virus and virus isolation attempts were negative. DNA from eight tumours was examined by dot-blot hybridization for the presence of sequences hybridizing with a full length clone of the RAV-2 strain of the avian leukosis virus. A positive reaction was detected with DNA from 6/8 tumours. Southern blot hybridization demonstrated the presence of a 7.2 kb fragment following restriction with BamHI and a 4.6 kb fragment in an additional tumour following digestion with EcoRI that were recognized by the RAV-2 probe. These results suggest the presence of a retrovirus in tumours of budgerigars.
