We report the recent emergence of a novel beak and feather disease virus (BFDV) genotype in the last remaining wild population of the critically endangered Orange-bellied Parrot (Neophema chrysogaster). This virus poses a significant threat to the recovery of the species and potentially its survival in the wild. We used PCR to detect BFDV in the blood of… (More)
Phylogenetic analyses of the highly genetically diverse but antigenically conserved, single-stranded circular, DNA genome of the avian circovirus, beak and feather disease virus (BFDV) from cockatoo species throughout Australia demonstrated a high mutation rate for BFDV (orders of magnitude fall in the range of 10(-4) substitutions/site/year) along with… (More)
Quasispecies variants and recombination were studied longitudinally in an emergent outbreak of beak and feather disease virus (BFDV) infection in the orange-bellied parrot (Neophema chrysogaster). Detailed health monitoring and the small population size (<300 individuals) of this critically endangered bird provided an opportunity to longitudinally track… (More)
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.
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… (More)
The complete genome sequence of beak and feather disease virus (BFDV) from a wild Australian Mallee ringneck parrot (Barnardius zonarius barnardi) was characterized. The genome consists of 1,995 nucleotides and encodes two major proteins in opposing directions. This is the first evidence of BFDV infectivity and the first complete genome sequence for this… (More)
Three complete genomes of beak and feather disease virus (BFDV) were recovered from wild twenty-eight parrots (Polytelis anthopeplus monarchoides). The genomes consisted of 1,996 bp with 1,934 identical sites and a typically content stem-loop structure between ORF1 and ORF2. This is the first report of BFDV infection as well as the complete genome sequences… (More)
The complete genome sequence of a beak and feather disease virus (BFDV) encoding two major open reading frames (ORFs) was characterized in a wild Moluccan red lory (Eos bornea). This is the first report of a BFDV genome from Indonesia and the first reported BFDV infection for this host species.
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… (More)
The presence of endogenous viral elements in host genomes hints towards much older host-virus relationships than predicted by exogenous phylogenies, with highly mutable single-stranded DNA (ssDNA) viruses and RNA viruses often occupying entangled multispecies ecological niches. The difficulty lies in unravelling the long-term evolutionary history of… (More)
