An efficient approach for recombinant expression and purification of the viral capsid protein from beak and feather disease virus (BFDV) in Escherichia coli

open access: yesJournal of Virological Methods, 2015
Structural insights into the biology of viruses such as beak and feather disease virus (BFDV) which do not replicate in cell cultures are increasingly reliant on recombinant methods for protein production and purification. Development of efficient methods for homogenous production of BFDV capsid protein is also essential for vaccine development and ...

Prevalence of BFDV in wild breeding Platycercus elegans

open access: yesJournal of Ornithology, 2019
Pathogens can have a profound impact on the population dynamics of avian populations. Beak and feather disease virus (BFDV) is considered one of the few pathogens capable of causing extinction, because it predominantly infects the highly threatened order Psittaciformes, the signs of disease are severe, and mortality can be extremely high.

Baculovirus expression of beak and feather disease virus (BFDV) capsid protein capable of self-assembly and haemagglutination

open access: yesJournal of Virological Methods, 2007
Beak and feather disease virus (BFDV) is a common avian circovirus infection of wild Psittaciformes and is a recognised threat to endangered psittacine species. Currently, there is a requirement to develop BFDV antigen for diagnostic purposes and since efforts to propagate BFDV in vitro have so far been unsuccessful the entire coding region of BFDV ORF

Seasonal fluctuation of beak and feather disease virus (BFDV) infection in wild Crimson Rosellas (Platycercus elegans) [PDF]

open access: yesScientific Reports, 2020
AbstractUnderstanding patterns of pathogen emergence can help identify mechanisms involved in transmission dynamics. Beak and feather disease virus (BFDV) poses a major threat world-wide to wild and captive parrots. Yet data from wild birds on seasonal fluctuations in prevalence and infection intensity, and thereby the potential high-risk times for ...

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

open access: yesJournal of Virological Methods, 2009
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 ...

Development and applications of a monoclonal antibody to a recombinant beak and feather disease virus (BFDV) capsid protein

open access: yesJournal of Virological Methods, 2008
The development of diagnostic assays for detecting beak and feather disease virus (BFDV) has traditionally been hampered by the difficulty associated with producing suitable reagents, namely purified virus and polyclonal antibodies. In an effort to develop a consistent and standardised source of antibody, a monoclonal antibody to a recombinant BFDV ...

Hematology of vaccinated and non-vaccinated long-billed corellas following infection with beak and feather disease virus (BFDV)

open access: yesComparative Clinical Pathology, 2009
The hematological characteristics of juvenile long-billed corellas (Cacatua tenurostris), with or without prior administration of a psittacine beak and feather disease vaccine, were studied for 97 days after experimental infection with beak and feather disease virus (BFDV).

Molecular characterisation of beak and feather disease virus (BFDV) in New Zealand and its implications for managing an infectious disease

open access: yesArchives of Virology, 2012
Beak and feather disease virus (BFDV) infections are often fatal to both captive and wild parrot populations. Its recent discovery in a wild population of native red-fronted parakeets has raised concerns for the conservation of native parrots, all of which are threatened or endangered.

Survey of Beak and Feather Disease Virus (BFDV) in Guatemalan Neotropical Psittacine Birds

Journal of Avian Medicine and Surgery, 2021
Beak and feather disease virus (BFDV), a circovirus, is the etiologic agent of psittacine beak and feather disease (PBFD), a progressive and often fatal disease in Psittaciformes. Even though neotropical psittacine species are more resistant to clinical infection than Old World species, BFDV is recognized as a threat to immunologically naïve wild ...

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

Zoonoses and Public Health, 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 ...
