Beak and feather disease virus- (BFDV-) positive (naturally infected) but clinically healthy budgerigars (Melopsittacus undulatus) were inoculated with two isolates ofMycobacterium aviumsubsp.aviumisolated from naturally infected golden pheasant (Chrysolophus pictus) and peafowl (Pavo cristatus). During a period of more than two months after inoculation, samples of cloacal and crop swabs, faeces, and blood were obtained for BFDV andMycobacterium aviumtesting with PCR. Birds were euthanized nine weeks after inoculation. All infected budgerigars developed signs typical of mycobacteriosis, but more advanced clinical and pathological changes were visible in the group infected with the pheasant isolate. Only a few cloacal and crop swab samples were positive forMycobacterium aviumsubsp.aviumdespite advanced pathological changes in the internal organs. In the groups infected with mycobacterium isolates the frequency of BFDV-positive samples was higher than in the control group. In the infected groups the frequency of BFDV was substantially higher in the cloacal swabs of birds inoculated with the pheasant isolate than in the peafowl-isolate-infected group.

Eight genomes of avian polyomaviruses (APVs) were recovered and sequenced from deceased Psittacula eupatria , Psittacula krameri , and Melopsittacus undulatus from various breeding facilities in Poland. Of these APV-positive samples, six had previously tested positive for beak and feather disease virus (BFDV) and/or parrot hepatitis B virus (PHBV).

Zusammenfassung:Bei Vögeln sind Circovirus-Infektionen seit langem bekannt. Neben dem Virus der infektiösen Anämie der Küken (chicken anaemia virus, CAV) ist hier vor allem das Virus der Schnabel- und Federkrankheit der Papageien (psittacine beak and feather disease virus, PBFDV) zu nennen. Die meisten Spezies der Ordnung Psittaciformes sowie einige andere Arten sind für das PBFDV empfänglich. Die Erkrankung manifestiert sich nicht nur bei den Nestlingen der Papageien, sondern auch bei adulten Vögeln. Bei diesen kommt es zu irreversiblen Schäden im Federkleid, bis hin zur vollständigen Federlosigkeit. Zudem erfahren infizierte Tiere eine starke Immunsuppression, die sie sehr anfällig für Sekundärinfektionen macht. Neben dem PBFDV wurden kürzlich weitere Circoviren beschrieben, die bei Tauben oder Kanarienvögeln vorkommen. In der vorliegenden Arbeit soll eine Übersicht über die Circovirus-Infektionen bei Ziervögeln und Tauben gegeben werden. Neben der klinischen Symptomatik sind die zur Zeit gebräuchlichen diagnostischen Nachweisverfahren und die Möglichkeiten zur Prophylaxe weitere Schwerpunkte.

Psittacine beak and feather disease (PBFD) is a common disease of the psittacine species and is caused by the psittacine beak and feather disease virus (PBFDV). In this study the occurrence of the disease in ring-neck parakeets and budgerigars in South Africa suffering from feathering problems, using polymerase chain reaction as a diagnostic test was investigated. The genetic variation between viral isolates was also studied. Results indicate that PBFDV can be attributed to being the cause of feathering problems in some of the ring-neck parakeets and budgerigars in South Africa. Genetic variation of isolates occurs between species and individuals. A cheap and easy to use method of blood sample collection on filter paper for diagnostic purposes was also evaluated. It proved to be less stressful to the birds and did not inhibit further processes.
