The Sensitivities of Various Erythrocytes in a Haemagglutination Assay for the Detection of Psittacine Beak and Feather Disease Virus

Journal of Veterinary Medicine, Series B, 2000
SummaryThe erythrocytes of various species were tested in psittacine beak and feather disease (PBFD) virus haemagglutination (HA) and haemagglutination inhibition assays to determine which are suitable for use in these assays. HA activity was observed for erythrocytes of the salmon‐crested cockatoo, the sulphur‐crested cockatoo, the umbrella cockatoo ...

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

Iranian journal of veterinary research, 2018
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 ...

Laboratory Reporting Accuracy of Polymerase Chain Reaction Testing for Psittacine Beak and Feather Disease Virus.

Journal of Avian Medicine and Surgery, 2009
Diagnostic assays that use polymerase chain reaction (PCR) methods are increasingly available to veterinarians. Psittacine beak and feather disease virus (family Circoviridae, genus Circovirus) is a pathogen of clinical importance for which PCR assays have been developed.

Hemagglutination by psittacine beak and feather disease virus and use of hemagglutination inhibition for detection of antibodies against the virus

American Journal of Veterinary Research, 1991
SUMMARY Conditions for psittacine beak and feather disease (pbfd) virus hemagglutination and hemagglutination-inhibition (hi) test reactions are defined. The pbfd virus was found to hemagglutinate cockatoo and some guinea pig erythrocytes. The hi test was used to assay serum antibody titer in birds with active pbfd virus infections and in others that ...

First detection of psittacine beak and feather disease virus in Croatia

Hrvatski veterinarski vjesnik - Hrvatsko veterinarsko društvo, 2005
Bolest kljuna i perja papiga (Psittacine Beak and Feather Disease-PBFD) neizlječiva je kronična bolest papiga. Očituje se degenerativnim promjenama pernih folikula zbog primarnog umnažanja uzročnog virusa (PBFDV) u bazalnom epitelu. To dovodi do pojave neurednog i zakržljalog perja, sve do njegovog ispadanja.

An advanced loop-mediated isothermal amplification assay for the rapid detection of beak and feather disease virus in psittacine birds

Journal of Virological Methods, 2020
Swarm primer-applied loop-mediated isothermal amplification (sLAMP) assay was developed for the rapid and specific detection of the ORF V1 gene of beak and feather disease virus (BFDV). The amplification can be completed in 40 min at 62 °C, and the results can be visually detected by the naked eye.

Detection of Beak and Feather Disease Virus (BFDV) and Avian Polyomavirus (APV) DNA in Psittacine Birds in Italy

Journal of Veterinary Medicine, Series B, 2005
SummaryBeak and feather disease (psittacine circovirus) and Budgerigar fledgling disease (avian polyomavirus) are viral diseases that can frequently affect captive psittacine birds. We designed the first survey to investigate the presence of beak and feather disease virus (BFDV) and Avian polyomavirus (APV) inside the population of captive psittacine ...

Prevalence of Aves Polyomavirus 1 and Beak and Feather Disease Virus From Exotic Captive Psittacine Birds in Chile

Journal of Avian Medicine and Surgery, 2019
Avian polyomavirus disease and psittacine beak and feather disease (PBFD) are both contagious viral diseases in psittacine birds with similar clinical manifestations and characterized by abnormal feathers. To determine the prevalence of Aves polyomavirus 1 (APyV) and beak and feather disease virus (BFDV) in captive, exotic psittacine birds in Chile ...

Species and Seasonality Can Affect Recent Trends in Beak and Feather Disease Virus Prevalence in Captive Psittacine Birds

Acta Tropica
Beak and feather disease virus (BFDV) is globally distributed in psittacine birds. BFDV is considered a key threat to biodiversity because it has the ability to transmit and shift between host species. Data from captive psittacine birds can help to identify potential risk factors for viral transmission management.
