Proventricular dilatation disease (PDD) is an incurable probably viral disease of psittacine birds. It was first recognized and described in 1978 by Dr. Hannis L. Stoddard. Since the first reported cases were involving species of macaw, the condition was termed macaw wasting syndrom
Avian bornaviruses have been reported, yet not proven, as the cause of proventricular dilatation disease (PDD), a disease of pet parrots. [7] While a report of research using a 'positive' brain cell culture (confirmed to contain an avian bornavirus) from a psittacine (parrot) that died with confirmed histopathological diagnosis of PDD ...
Bornaviridae is a family of negative-strand RNA viruses in the order Mononegavirales.Horses, sheep, cattle, rodents, birds, reptiles, and humans serve as natural hosts. Diseases associated with bornaviruses include Borna disease, a fatal neurologic disease of mammals restricted to central Europe; and proventricular dilatation disease (PDD) in b
Avian bornaviruses, a group of related viruses, have been reported, yet not proven, as the cause of proventricular dilatation disease (PDD), a disease of pet parrots. The use of a 'positive' brain cell culture containing ABV to inoculate another psittacine (parrot) bird resulted in the inoculated bird's death and subsequent histopathological ...

This species is known to suffer from proventricular dilatation disease, also known as "macaw wasting disease", a fatal inflammatory disease of the nerves of the upper and middle digestive tract. It is typified by a swollen proventriculus and tiny lesions which appear in the ganglia and nerves, and the affected birds show abnormal movements and ...
Psittacine beak and feather disease was first described in the early 1980s and has become recognised as the dominant viral pathogen of psittacine birds worldwide. In wild red-rumped grass parakeets (Psephotus haematonotus), a case of feather loss syndrome that was highly suggestive of PBFD was first recorded in South Australia in 1907. [2]
A salmon-crested cockatoo, showing signs of feather-plucking on its chest. Feather-plucking, sometimes termed feather-picking, feather damaging behaviour or pterotillomania, [1] is a maladaptive, behavioural disorder commonly seen in captive birds that chew, bite or pluck their own feathers with their beak, resulting in damage to the feathers and occasionally the skin.
