Detection of beak and feather disease virus in India and its implications
Transboundary and Emerging Diseases, 2022Beak and feather disease virus (BFDV) has been found in Oceania, Africa, Asia and Europe, but the virus has not yet been detected in India. Here we are reporting the detection of BFDV in exotic rainbow lorikeets (Trichoglossus haematodus) in India. In the phylogenetic analysis, India's witnessed BFDV complete genome, replication (Rep) and capsid (Cap ...

Fluctuation of the prevalence of beak and feather disease virus in captive psittacines in Iran
Archives of Virology, 2023Beak and feather disease virus (BFDV) is one of the most life-threatening viral agents infecting parrot species. In this study, we investigated fluctuation in the prevalence of beak and feather disease virus (BFDV) in captive psittacines in Iran. Two series of feather samples from different psittacine species, received between July 2019 and July 2021 ...

Routes and prevalence of shedding of psittacine beak and feather disease virus
American Journal of Veterinary Research, 1991SUMMARY Psittacine beak and feather disease (pbfd) virus was recovered from the feces and crop washings from various species of psittacine birds diagnosed with pbfd. High concentrations of the virus also could be demonstrated in feather dust collection from a room where 22 birds with active cases of pbfd were being housed.

The phylogenetic and recombinational analysis of beak and feather disease virus Taiwan isolates
Archives of Virology, 2016Beak and feather disease virus (BFDV) is an avian circovirus, and it has a single-stranded DNA genome. It causes a fatal disease in parrots called psittacine beak and feather disease (PBFD). After screening of samples collected from Taiwan using PCR, complete genome sequences of isolates from 21 samples from various species of parrot were obtained. The

A novel genotype of beak and feather disease virus in budgerigars (Melopsittacus undulatus)
Virus Genes, 2010Beak and feather disease virus (BFDV) is a causative agent for psittacine beak and feather disease (PBFD), which shows a characteristic feather disorder in psittacine birds. Nineteen budgerigars, which were clinically suspected to have PBFD, were examined by two polymerase chain reactions (PCR), which target each of open reading frames (ORFs) V1 and C1.

Characterization of a new virus from cockatoos with psittacine beak and feather disease
Virology, 1989A novel virus isolated from the feather follicles of cockatoos diagnosed as having psittacine beak and feather disease was characterized by electron microscopy, nucleic acid content, and polypeptide composition. Purified virions displayed an icosahedral symmetry, were nonenveloped, and had a mean diameter of 14 to 16 nm negatively stained.

SummaryPsittacine beak and feather disease (PBFD) is the most common viral disease of wild and captive psittacine birds. Here, we designed the first survey to investigate the existence of subclinical infections and the distribution of the causative agent named beak and feather disease virus (BFDV) inside the population of captive psittacine birds in ...

Genetic diversity of the Rep gene of beak and feather disease virus in South Africa
Archives of Virology, 2006A study on the genetic variation of Beak and feather disease virus (BFDV) isolates in South Africa was performed by amplifying and sequencing a region within the ORF1 of the genome. Six different BFDV isolates were found in 15 psittacine species from 6 regions within South Africa, representing three unique isolates and three isolates that clustered ...

Archives of Virology, 2019
Beak and feather disease virus (BFDV) belongs to the family Circoviridae. A rolling-circle replication strategy based on a replication-associated protein (Rep) has been proposed for BFDV. The Rep gene of BFDV was expressed and purified, and it was shown to cleave short oligonucleotides containing the conserved nonanucleotide sequence found in the ...
