Avian Bornavirus is Present in Many Tissues of Psittacine Birds with Histopathologic Evidence of Proventricular Dilatation Disease [PDF]

Journal of Veterinary Diagnostic Investigation, 2010
Proventricular dilatation disease (PDD) is a neurologic disease of psittacine birds suspected to be caused by a recently identified Avian bornavirus (ABV). In the current report, data supporting the causal association of ABV with PDD are presented. Immunohistochemistry (IHC) with rabbit polyclonal antiserum raised against ABV nucleocapsid protein was ...

Identification of Mixed Infections with Different Genotypes of Avian Bornaviruses in Psittacine Birds with Proventricular Dilatation Disease

Avian Diseases, 2012
Proventricular dilatation disease (PDD) is a fatal, progressive neurological disorder of psittacine birds, which is caused by a single-stranded RNA virus, the avian bornavirus (ABV). The disease pattern includes lymphoplasmacytic inflammation of the central, peripheral and autonomic nervous system.

Proventricular Dilatation Disease in Cockatiels (Nymphicus hollandicus) After Infection With a Genotype 2 Avian Bornavirus

Journal of Avian Medicine and Surgery, 2011
An isolate of genotype 2 avian bornavirus (ABV) was recovered from a cockatiel (Nymphicus hollandicus) that was euthanatized for an unrelated lesion and showing no clinical evidence of proventricular dilatation disease (PDD). On histopathologic examination, mild inflammatory lesions were present in the heart and brain, but gastrointestinal lesions ...

Blindness as a sign of proventricular dilatation disease in a grey parrot (Psittacus erithacus erithacus)

Journal of Small Animal Practice, 2008
An approximately eight‐year‐old female grey parrot (Psittacus erithacus erithacus) was presented with a two months history of blindness. The radiographic examination showed a dilatation of the proventriculus, ventriculus and gut. Ophthalmoscopy and electroretinography revealed degeneration of the retina.

First finding of proventricular dilatation disease in Croatia

2007
The poster documents the first finding of proventricular dilatation disease in farm-reared psittacine birds in Croatia. According to clinical signs, gross lesions and histopathologic examination the disease was confirmed in a medium sulphur-creasted cockatoo (Cacatua galerita eleonora) and a blue and gold macaw (Ara ararauna).

[Proventricular dilatation disease and Avian Bornavirus as a possible cause].

Tierarztliche Praxis. Ausgabe K, Kleintiere/Heimtiere, 2012
Proventricular Dilatation Disease (PDD) is a very important letal disease in parrots. It affects several psittacine species and is a high risk factor for the health of breeding collections, but is rarely observed in other avian families. To date, the etiology of the disease remained unclear, though a virus infection was always assumed.

UNUSUAL AND SEVERE LESIONS OF PROVENTRICULAR DILATATION DISEASE IN LORIES

2017
During the early ’90s, anecdotally lories were considered refractory to PDD. Subsequently, the disease has been identified in them. We describe PDD in lories with unusual clinical history, histopathology and virology. Thirteen lories were necropsied during 2011-2016.

Avian bornavirus and proventricular dilatation disease: diagnostics, pathology, prevalence, and control.

The veterinary clinics of North America. Exotic animal practice, 2013
Avian bornavirus (ABV) has been shown the cause of proventricular dilatation disease (PDD) in psittacines. Many healthy birds are infected with ABV, and the development of PDD in such cases is unpredictable. As a result, the detection of ABV in a sick bird is not confirmation that it is suffering from PDD. Treatment studies are in their infancy. ABV is

Update on Avian Bornavirus and Proventricular Dilatation Disease: Diagnostics, Pathology, Prevalence, and Control.

The veterinary clinics of North America. Exotic animal practice, 2020
Avian bornavirus (ABV) is a neurotropic virus that can cause gastrointestinal and/or neurologic signs of disease in birds. The disease process is called proventricular dilatation disease (PDD). The characteristic lesions observed in birds include encephalitis and gross dilatation of the proventriculus. ABV is widely distributed in captive and wild bird

CAMPYLOBACTER JEJUNI AND PROVENTRICULAR DILATATION DISEASE IN PARROTS: THERE MAY BE A CORRELATION?

2015
While Avian Borna Virus (ABV) appears to be the causative agent of PDD, the relationship of ABV in the pathogenesis of this disease remains unclear. In an epidemiological survey, ABV was present in many but not all parrots with symptoms of PDD1- 3. The signifi cance of this disjunct suggests that there may be at least an additional factor at play. This
