Proventricular Dilatation Disease (PDD) In Parrots
PDD was first discovered in 1978 by esteemed bird veterinarian Dr. Hannis L. Stoddard. At the time, the cause of PDD was believed to be from an infectious organism or parasite. In 2008, however, University of California researchers identified the Avian Bornovirus (ABV), which they now believe to be the cause of PDD. If a parrot contracts ABV, unfortunately there's a good chance they will develop PDD.
Although veterinarians and researchers have identified PDD in over 50 different parrot species, some species are more susceptible to this disease than others. Amazon parrots, Macaws, African Greys, cockatoos, Eclectus parrots and conures are at a greater risk for developing PDD. In addition, parrots are more susceptible to PDD between the ages of 2 and 4 years of age.
PDD affects parrots in a few different ways, one of which is an intestinal disorder. Parrots suffering from PDD may stop eating, spit up their food, experience irregular bowel movements, and have exceptionally watery poop. PDD is known to gradually damage the host's intestinal lining, creating a wide variety of unpleasant symptoms for the parrot. Also, some parrots may experience neurological problems associated with PDD as well, such as lethargy, behavioral changes, etc.
Unfortunately, there's currently no cure for PDD. By identifying the disease early, though, owners and their veterinarians can treat some of the unpleasant symptoms associated with this disease. If you notice any of the symptoms listed above, talk with your veterinarian for a more professional and thorough investigation.
