Abstract

Three complete genomes of beak and feather disease virus (BFDV) were recovered from wild musk lorikeets (Glossopsitta concinna). The genomes consisted of 2,008 to 2,010 nucleotides (nt) and encode two major proteins transcribing in opposing directions. This is the first report of BFDV complete genome sequences obtained from this host species.

Highlights

  • Three complete genomes of beak and feather disease virus (BFDV) were recovered from wild musk lorikeets (Glossopsitta concinna)

  • The etiological agent of the disease, beak and feather disease virus (BFDV), is a compact circular, ambisense, single-stranded DNA virus belonging to the genus Circovirus in the family Circoviridae [2, 3], and it is perhaps the simplest pathogen known to infect vertebrates

  • Lories and lorikeets are members of the relatively young (10 Ma) parrot subfamily Loriinae, which is confined to Australasia [7, 8], and new research has revealed that BFDV in lorikeets are sympatrically sequestered and divergent from those circulating in other psittacine hosts [9]

Summary

Introduction

Three complete genomes of beak and feather disease virus (BFDV) were recovered from wild musk lorikeets (Glossopsitta concinna). The etiological agent of the disease, beak and feather disease virus (BFDV), is a compact circular, ambisense, single-stranded DNA (ssDNA) virus belonging to the genus Circovirus in the family Circoviridae [2, 3], and it is perhaps the simplest pathogen known to infect vertebrates. All Psittaciformes are considered susceptible to infection, since BFDV has been reported in more than 60 species of cockatoos and parrots [4,5,6].
