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.

The complete genome sequence of beak and feather disease virus (BFDV) from a fledgling red-capped parrot ( Purpureicephalus spurius ) was assembled and characterized. The genome consists of 1,995 nucleotides and encodes two major proteins in opposing directions. This is the first evidence of BFDV infectivity and a complete genome sequence for this novel host.

Psittacine beak and feather disease (PBFD) is a common viral disease of wild and captive psittacine birds characterized by symmetric feather loss and beak deformities. The causative agent, beak and feather disease virus (BFDV), is a small, circular single-stranded DNA virus that belongs to the genus Circovirus. BFDV can be detected by PCR or the use of haemagglutination (HA) and haemagglutination inhibition (HI) assays that detect antigen and antibodies respectively. Erythrocytes from a limited number of psittacine species of Australian origin can be used in these tests. In South Africa, the high cost of these birds makes them difficult to obtain for experimental purposes. Investigation into the use of erythrocytes from African Grey parrots and Brown-headed parrots yielded positive results showing the haemagglutinating activity of their erythrocytes with purified BFDV obtained from confirmed clinical cases of the disease. The HA activity was further confirmed by the demonstration of HI using BFDV antiserum from three different African Grey parrots previously exposed to the virus and not showing clinical signs of the disease.
