Abstract

Psittacine Beak and Feather Disease (PBFD) was listed in April 2001 as a key threatening process under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and it is a disease threat to the critically endangered orange‐bellied parrot (Neophema chrysogaster) and at least 25 other Australasian bird species or subspecies that are listed as either endangered or
vulnerable under provisions of the EPBC Act (Table 1). PBFD causes either a chronic debilitating feather disease in adult birds ( Pass and Perry, 1985; Ritchie et al., 1989b; Rahaus and Wolff, 2003; Albertyn et al., 2004) or a severe, acute disease syndrome in nestling parrots (Raidal and Cross, 1995; Schoemaker et al., 2000). The causative agent, BFDV, is a circovirus with a small single stranded DNA genome of only 1.7‐2.0 kb (Ritchie et al., 1989; Bassami et al., 2001) and is now considered to have a worldwide distribution (McOrist et al., 1984; Pass and Perry, 1985; Ritchie et al., 1989a; Kock et al., 1993; Kiatipattanasakul‐Banlunara et al., 2002; Rahaus and Wolff, 2003; Albertyn et al., 2004; Hsu et al., 2006). Surveys using PCR‐based assay methods have found prevalence rates of between 8% (Bert et al., 2005) and 39% (Rahaus and Wolff, 2003) and the reported seroprevalence varies between 16% and 62% (Raidal and Cross, 1994; Khalesi et al., 2005) among captive flocks and between 41% and 94% in wild flocks (Raidal et al., 1993).
