I received this email and thought I would pass it on to all of you. Good news - we are making progress - bad news - there is no silver bullet yet.


Latest clinical update on Proventricular Dilation Disease (PDD)

Avian Bornavirus is the major known virus that induces nerve inflammation known as avian ganglioneuritis. Therefore it has been recommended that instead of calling the clinical form of the disease PDD we should refer to the clinical manifestation of the nerve inflammation Avian Ganglioneuritis (AG). Other viruses can cause AG (PDD) and that will be scientifically found in the coming few years.

A new test identifying AG is coming out in October (ish) and will help to identify the nerve damage and inflammation and therefore the clinical status of PDD. For now we'll just say that PDD (AG) will be differentiated between being Avian Bornavirus positive and clinical disease.

Identification of Avian Bornavirus status is important and may help avian veterinarians to differentiate other symptoms that are not in the gastrointestinal system (the GI tract). Weakness, incoordination, seizures, and even feather destructive behaviors may be a result of the effects of Avian Bornavirus. Avian Bornavirus can be transmitted laterally (from bird to bird) in stressed birds. Reproductive stress may be a main contributor to its transmission and transformation from non-clinical to clinical. Potentially more important than from bird to bird is that the virus is transmitted directly into the egg itself.

The virus can be carried and just intermittently shed. One in three parrots will be positive. A small fraction of those will go on to develop clinical disease. In other words, a positive test means pay attention, don't panic, make informed decisions, and discuss with a qualified avian vet to discuss the latest treatments. The latest treatments include Celebrex that is given daily and an injectable medication given every 5-7 days called Onsior. The medication is available from Australia where we get it. We stock it at the office and it will be arriving soon. Treatment consists of controlling the nerve damage (inflammation) not killing the virus. Lastly, a vaccine is being tested and hopefully will aid in the prevention of clinical disease.

Thank you, Association of Avian Veterinarians, Dr. Bob Dalhausen, Dr. Rossi, and Dr. Susan Orosz for all that you do for birds and research.

Just remember Polio, a massive killer, was whipped and is virtually unknown today.
