Abstract
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 whole-genome sequence of beak and feather disease virus (BFDV) from a wild Australian regent parrot (Polytelis anthopeplus monarchoides) was characterized
Beak and feather disease virus (BFDV) is one of the smallest and simplest pathogens, in terms of both genome and particle size, of any vertebrate, and it causes psittacine beak and feather disease (PBFD). It belongs to the family Circoviridae [1,2,3], with the circular single-stranded DNA genome of BFDV surrounded by a nonenveloped icosahedral capsid 19 to 22 nm in diameter, and it must use host cell machinery to replicate [4, 5]
BFDV is reported for the first time in a wild regent parrot in Australia
Summary
The whole-genome sequence of beak and feather disease virus (BFDV) from a wild Australian regent parrot (Polytelis anthopeplus monarchoides) was characterized. Beak and feather disease virus (BFDV) is one of the smallest and simplest pathogens, in terms of both genome and particle size, of any vertebrate, and it causes psittacine beak and feather disease (PBFD). The emergence of the disease in critically endangered species has been recently highlighted as a key threat to the orange-bellied parrot [6].
