Abstract
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 three psittacine
beak and feather disease (PBFD) –affected wild Orange-bellied Parrot fledglings captured as
founders for an existing captive breeding recovery program. Complete BFDV genome sequence
data from one of these birds demonstrating a 1,993-nucleotide-long read encompass the entire
circular genome. Maximum-likelihood (ML) and neighbor-joining (NJ) phylogenetic analysis
supported the solitary position of this viral isolate in a genetically isolated branch of BFDV. On Rep
gene sequencing, a homologous genotype was present in a second wild orange-bellied parrot and
the third bird was infected with a distantly related genotype. These viruses have newly appeared in
a population that has been intensively monitored for BFDV for the last 13 yr. The detection of two
distinct lineages of BFDV in the remnant wild population of Orange-bellied Parrots, consisting of
fewer than 50 birds, suggests a role for other parrot species as a reservoir for infection by spillover
into this critically endangered species. The potential for such a scenario to contribute to the
extinction of a remnant wild animal population is supported by epidemiologic theory.
