Beak and feather disease virus genotypes in Australian parrots reveal flexible host-switching Academic Article uri icon

abstract

  • To discover beak and feather disease virus (BFDV) genotypes in Australian parrots that might threaten vulnerable and endangered psittacine bird species.Phylogenetic analyses of new DNA sequence data from Australian birds including the Rep gene (n = 55) and nine whole genomes, were compared with all available published BFDV genomes to assess host- and geographically-based divergence as well as probable host-switch events.Strong support for flexible host-switching and recombination was detected, indicating active cross-species transmission in various subpopulations.The data suggested that all endangered Australian psittacine bird species are equally likely to be infected by BFDV genotypes from any other close or distantly related host reservoir species.
