What is Proventricular dilatation disease?
Proventricular dilatation disease (PDD) is a condition affecting the nerves that supply the gastrointestinal tract of birds, especially the proventriculus or true stomach. Nerves supplying other organs may also be affected, and in some cases, encephalitis (inflammation of the brain) may occur.
How is PDD diagnosed in birds?
Radiographs (X-rays) are the most immediately useful diagnostic tool, and often demonstrate the classic severe dilatation of the proventriculus (true stomach). Specific tests, including DNA and antibody tests from blood samples, have been developed and show promise.

What is ABV infection?
Both ABV and BDV infect the central nervous system (CNS) and the peripheral nervous system (PNS) and induce viral encephalitis and polyneuritis with selective destruction of Purkinje cells, lymphocyte infiltration, and dysfunction of the CNS, PNS, and the autonomic nervous system.
Is ABV contagious?
Recent studies suggest that this virus is often spread from parents to chicks, and possibly through eggs. While this is a contagious disease, observation in ABV infected aviaries show that this virus does not spread rapidly throughout a flock.
Is PDD curable parrots?
There is no cure for PDD, so treatment reduces inflammation and the other symptoms. How do you prevent it? Infected birds should be isolated for life to prevent the virus spreading to other pet birds.
Where is psittacosis found?
