ABSTRACT Circoviruses are small, nonenveloped icosahedral animal viruses characterized by circular single-stranded DNA genomes. Their genomes are the smallest possessed by animal viruses. Infections with circoviruses, which can lead to economically important diseases, frequently result in virus-induced damage to lymphoid tissue and immunosuppression. Within the family Circoviridae, different genera are distinguished by differences in genomic organization. Thus, Chicken anemia virus is in the genus Gyrovirus, while porcine circoviruses and Beak and feather disease virus belong to the genus Circovirus. Little is known about the structures of circoviruses. Accordingly, we investigated the structures of these three viruses with a view to determining whether they are related. Three-dimensional maps computed from electron micrographs showed that all three viruses have a T=1 organization with capsids formed from 60 subunits. Porcine circovirus type 2 and beak and feather disease virus show similar capsid structures with flat pentameric morphological units, whereas chicken anemia virus has stikingly different protruding pentagonal trumpet-shaped units. It thus appears that the structures of viruses in the same genus are related but that those of viruses in different genera are unrelated.

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.
