Research on Proventricular Dilatation Syndrome

Proventricular Dilatation Syndrome or Proventricular Dilatation Disease (PDD) is a fatal progressive and often contagious disease of domestic and wild parrots worldwide. Recent studies have shown the suspicions maintained by scientists about the specific viral cause of this illness. Loro Parque Foundation and the University of Giessen in Germany, have taken an important step in this direction.

Objectives
Obtain new scientific insights into the pathogenesis of the disease and its relation to avian bornavirus and / or paramyxovirus in psittacine birds.

Strategies
Characterization of potential virus strains isolated by genomic sequencing, viral proteins and infection processes. Evaluation of the role of these virus strains in the pathology of PDD, in order to develop tools for its control.

Actions
The team has worked with more than 2,400 samples of at least 1,500 parrots in Spain and Germany, with and without suspicion of having the disease. Examination of the presence of avian bornavirus and/or paramyxovirus in them discarded the latter as a factor of the pathogenesis. However, in the case of avian bornavirus strains the coincidences were significant.
