Abstract:
OBJECTIVE: To discover beak and feather disease virus (BFDV) genotypes in Australian parrots that might threaten vulnerable and endangered psittacine bird species. METHODS: 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. RESULTS: Strong support for flexible host‐switching and recombination was detected, indicating active cross‐species transmission in various subpopulations. CONCLUSION: 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.
