COLLEGE 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
"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.
For more information on our PDD research and the other
activities of the
Schubot Center contact Dr Tizard at firstname.lastname@example.org.
