Schubot researchers image Avian Borna Virus

Avian Borna VirusCOLLEGE STATION, TX – Scientists working at the Schubot Exotic Bird Health Center at Texas A&M’s College of Veterinary Medicine have finally visualizedthe Avian Borna Virus, the cause of Proventricular Dilatation Disease in parrots. Using advanced electron microscopy, a team of scientists at the Schubot Center led by Dr Ian Tizard, have succeeded in photographing avian Borna Virus.

“Although we have been culturing the agent for many months,” said Tizard, “this virus seems to move between cells in the form of a molecular complex rather than a complete virus. As a result, despite repeated attempts, we have never been able to see the virus. Recently however we found that some body fluids in infected birds contain very large amounts of the virus. By examining these fluids we found numerous viral particles.”

An example is seen at left.

The research team is continuing its characterization of the virus. Other studies on PDD are continuing including investigations into appropriate therapy and prevention techniques.
