Psittacine beak and feather disease in a free-living ring-necked parakeet (Psittacula krameri) in Great Britain

Molecular detection and characterization of beak and feather disease virus in psittacine birds in Tehran, Iran

Beak and feather disease virus (BFDV), a member of genus circovirus, is a small, non-enveloped, single stranded DNA virus. Although BFDVs are among the most well studied circoviruses, there is little to no information about BFDVs in Iran. The aim of the present study was to detect and identify BFDV molecules from the birds referred to the avian clinic of The Faculty of Veterinary Medicine, Tehr...

Nestling Development of Ring-necked Parakeets (Psittacula krameri) in a Nest Box Population

Chick development of a population of non-native Ring-necked Parakeets (Psittacula krameri) (RNP) has been investigated between 2006 and 2008 in Heidelberg, Germany. In parrots hatching asynchrony is common. RNP chicks are under natural selection to fledge synchronously with their siblings, as parents return less often to the nest after the first chick has fledged and remaining chicks may starve...

Psittacine beak and feather disease virus in budgerigars and ring-neck parakeets in South Africa.

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 ...

Detection of Beak and Feather Disease Virus and Avian Polyomavirus Dna in Psittacine Birds in Poland

The first survey on the incidence of beak and feather disease virus (BFDV) and avian polyomavirus (APV) among the captive psittacine birds in Poland was presented in this study. Samples were collected between 2006 and 2009. A total number of 751 symptom–free birds from 31 genera and 59 species were tested for BFDV and APV by means of a PCR assay. BFDV was found in 25.3% and APV in 22.24% of the...
