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...

Incidence and detection of beak and feather disease virus in psittacine birds in the UAE

Beak and feather disease is caused by Circovirus, which affects actively growing beak and feather cells of avian species. The disease affects mainly young birds while older birds may overcome the disease with few lasting effects. Due to lack of treatment, the only way to control the disease is through hygiene and early diagnosis. As a diagnostic tool, we have established a Taqman probe based re...

Isolation and Characterization of Psittacine Beak and Feather Disease Virus in Saudi Arabia Using Molecular Technique

Psittacine Beak and Feather Disease (PBFD) is a contagious, fatal viral disease that affects the beak, feathers, and immune system of wild and captive old and New World Psittacine. PBFD is characterized by feather abnormalities, beak and claw deformities and eventually dying as a result of immunosuppressant. The disease is caused by member of the genus circovirus in the family Circoviridae. The...

Genetic analysis of beak and feather disease virus isolated from captive psittacine birds in Thailand.

Beak and feather disease virus (BFDV) is a causative agent of psittacine beak and feather disease. Genome sequences of BFDVs isolated from Thailand have not hitherto been reported. The whole genomes of 17 BFDV isolates, obtained from 12 psittacine genera, were amplified and subjected to direct sequencing revealing a length ranging from 1,990 to 2,015 nucleotides. The predicted open reading fram...

A blocking ELISA for the detection of antibodies to psittacine beak and feather disease virus (BFDV).

Currently, the only diagnostic test available routinely for the sero-diagnosis of BFDV is the haemagglutination-inhibition (HI) assay. This test, whilst useful and applicable to samples from a wide range of psittacine birds, is not an ideal assay; it requires erythrocytes from live animals, virus purified from the feathers of infected birds and polyclonal antibody preparations in order to perfo...
