PCR-based assays for the detection of BFDV DNA are in widespread use throughout the world. Quan-titative real-time PCR assays are extremely sensitive and have the advantages over standard PCRassays that they do not require post-reaction processing to visualise PCR products and can quan-tify the amount of DNA present in a sample. This study describes a quantitative real-time PCR assa...
Eight genomes of avian polyomaviruses (APVs) were recovered and sequenced from deceased Psittacula eupatria, Psittacula krameri, and Melopsittacus undulatus from various breeding facilities in Poland. Of these APV-positive samples, six had previously tested positive for beak and feather disease virus (BFDV) and/or parrot hepatitis B virus (PHBV).
Since the characterization of psittacine beak and feather disease (PBFD) in 1984, a wide range of avian circoviruses have been discovered with varying pathogenic effects amongst a diverse range of avian hosts. Until recently these circovirus species were thought to be restricted to within avian Orders such as the Psittaciformes for beak and feather disease virus (BFDV) and Columbiformes for pig...
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 ...
The complete nucleotide (nt) sequence of beak and feather disease virus (BFDV) was determined. The viral genome consists of 1,991 nt, including an 870-nt open reading frame 1 (ORF1), a 744-nt ORF2, a conserved stem-loop structure, and the second hairpin. This is the first reported detection of BFDV in an infected African grey parrot in China.
Two complete genomes of beak and feather disease virus (BFDV) were characterized from Lathamus discolor, the Australian swift parrot. This is the first report of BFDV complete genome sequences in this host. The completed BFDV genomes consist of 1,984 nucleotides encoding two open reading frames with 99.7% pairwise nucleotide identity.
The whole-genome sequence of beak and feather disease virus (BFDV) from a wild Australian regent parrot (Polytelis anthopeplus monarchoides) was characterized. The genome consists of 1,993 bp and has a typical stem-loop structure between open reading frame 1 (ORF1) and ORF2. This is the first evidence of BFDV infection as well as the complete genome sequence for this host species, globally.
The complete genome sequence of beak and feather disease virus (BFDV) was discovered from a rainbow bee-eater (Merops ornatus), a species of Coraciiformes The genome consisted of 1,996 bp encoding two major bidirectional transcribed open reading frames. This is the first evidence of BFDV infection and complete genome characterization for this novel host species.
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...
