(2009) Avian bornaviruses in psittacine birds from Europe and Australia with proventricular dilatation disease. Emerg Infect Dis. Available from http://www.cdc.gov/EID/content/15/9/1453.htm. Abstract: To determine whether avian bornaviruses (ABVs) were a factor in proventricular dilatation disease (PDD), we used immunohistochemistry, reverse transcription–PCR, and nucleotide sequence analysis to examine paraffin wax–embedded or frozen tissue samples of 31 psittacine birds with this disease. PDD is a fatal disease of psittacine birds associated with nonsuppurative encephalitis and ganglioneuritis of the upper intestinal tract. Tissue samples had been collected from 1999 through 2008 in Austria, Switzerland, Hungary, and Australia.

R Woods		18/02/2009	PDD is a serious problem in aviculture in the USA and Europe. It particularly becomes problematic when an aviary is crowded and poorly ventilated. It appears that the causative agent is not particularly stable in the environment. The implication of this is that, while Australian birds can be infected, widespread contagion in the wild is unlikely. It has not been described in wild birds in Australia.
