Pigeon flyers around the world have all heard of paramyxovirus or PMV. This is a viral disease that is not to be confused with the bacterial disease paratyphiod caused by Salmonella typhimurium. PMV is caused by one of the serotypes of PMV1 viruses which happens to be closely related to another PMV1 virus that causes Newcasle Disease. We will mention this again when it comes to vaccination. PMV first started in the late 1970’s in the middle east and has since been found everywhere that pigeons are raised.
The virus is not very tough and dies quickly in the environment. Once a bird is infected it will shed the virus in the droppings and other secretions for three weeks. Between exposure and clinical signs, however, can vary immensely, from a few days to several weeks. This can be a big problem in futurity lofts when YB’s are shipped that are shipped that are infected and shedding the virus, yet are not showing clinical signs. They can have an entire loft exposed before you ever know you have a problem.
Clinical signs are primarily related to two organ systems. The kidney and the nervous system. This virus ALWAYS causes an inflammation of the kidney called interstitial nephritis. When this occurs the white portion of the droppings changes to water and you often find puddles of water on the perches. Within that puddle will be NORMAL fecal material in the form of green or brown “worms”. This is NOT a true diarrhea since the fecal material from the intestine is normal. Since the kidney changes are uniform in the flock of infected pigeons, the kidney is the organ of choice to send to the lab for diagnosis. The changes in the kidney seen under the microscope, when coupled with clinical signs, provide you with a pretty sure diagnosis. These watery droppings can persist for 2 to 3 months after infection in a flock of pigeons. The second organ system involved is the nervous system. The two main signs we see are nerve paralysis shown as a lameness or dropped wing, or torticollis ( twisted necks). When this disease 1st hit the scene the neurological signs were very prevalent. Recently, however, these symptoms only seem to show up in 10 to 20% of the birds at the most. Most pigeons with the neurological signs will recover if they can eat and drink. Therefore, if you have neglected vaccination and you get this bug in your loft you don’t have to destroy good pigeons. Just make sure they eat and drink and you will have the vast majority come back to normal, even to race again.
Vaccination for this disease is critical since there are only two types of unvaccinated pigeons, those that have the disease and those that are going to get it sometime. You may have been lucky so far but you will not be forever. By far and away the only PROVEN method of vaccination is to use the injectable pigeon PMV vaccine. There is on made in the States by Maine Biological Labs and several in Europe. Unfortunately, a lot has been said about the use of the chicken “LaSota” vaccine available in the U.S. and Canada. This is NOT a pigeon virus, and is made to inoculate chickens against Newcastle disease which we mentioned earlier. It has been variously promoted to be dripped in the eyes, the nose, or placed in the drinking water. This vaccine will in no way harm your birds, but EVERY study has shown it to be ineffective. I personally have had several lofts in the states send in PMV infected birds that were inoculated with the “LaSota” vaccine and yet still had the disease. The injectable vaccine has also been incriminated by some excellent flyers as harming performance. My experience with the injectable vaccine in my loft and many other ALL-AMERICAN lofts is that it does NOT HURT PERFORMANCE. In short, if you use the “LaSota” type vaccine and your birds get sick, it is your fault, you have been warned. In fairness to the “LaSota” vaccine, many flyers use it as an immune stimulant in the water before a big race with excellent results. I personally have not had experience in that area, I have never used it to know.
Treatment for PMV is only symptomatic. NO drugs that you can give the pigeon will kill the virus ( without killing the bird). Simply do the following:
Make sure infected birds eat and drink Make sure that other diseases are not present, cocci, worms, canker, ect. If 2nd infections like E. coli show up, treat with the appropriate antibiotic base on cultures at the vet.
So, in short, what does the pigeon flyer need to know about PMV.
It is out there and vaccination with the injectable vaccine is critical. Symptoms primarily are watery droppings and neurological signs. Infected birds usually survive with supportive care.
Remember, PMV is a terrible and devastating disease for the pigeon fancier to deal with. But, there is NO reason to ever have to deal with it because of an effective vaccine.

THANK YOU VERY MUCH FOR THE ARTICLE ON PMV.
How good is la sota
How get medecine of paramyxovirus. pls send name of medicine and how treatment daily
i have nursed a number of pigeons back to health from this virus with very good results.
the first thing is to isolate them from other pigeons,keep them in a warm and quite environment clean regularly, i gave them a course of baytril 2.5%, 5ml mixed in 1 pint of water for seven days, i administered it by using a syringe and VERY CAREFULLY IN VERY SMALL QUANTITY’S injected it directly into there mouths so that i knew they were getting it,after that i gave them a glucose and vitamins supplement mixed in there water complemented with pigeon condition seed.
it took around 8 weeks but all have recovered and looking well
I had a very hard time last summer when most of my young birds were infected with Paramyxo Virus.It took me a few weeks before I could identify the virus,because the first signs were watery droppings and so I treated all my pigeons against intestine disease.My birds got worse every day and I also had some mortality as well.After some time I had single birds loosing their balance and this was the time when I was sure that I had the virus in my loft.I started a ten day course of Batril followed with seven days of probiotics.My birds showed immediate improvement,but those birds which were highly infected and twisting there head and loosing balance had to be destroyed because they did not get any better.

Newcastele الـتواء الـعـنـق
اسهال مائي مع التواء الرقبة الى اسفل وعدم توازن الاعصاب – فقدان في الوزن وهزال الجسم
موت الفراخ الصغيرة في اعشاشها وكذلك عدم نمو الريش بانتظام عند الصغار مما يجعل نهاية الريش متقصف بسبب المرض
وهو من اخطر الامراض التي تصيب الحمام لسرعة انتشاره بين الحمام في الحظائر
ليس هناك علاج فعال 100% ولكن يوجد علاج وقاية من هذا المرض قبل الاصابة به وهناك بعض الاحتياطات واجب العمل بها كما هي
الحمام المصاب بعيدا عن الحظائر التي غير مصابة
اعطاء جميع الحمام مضاد حيوي ودواء لحماية المتبقي من المرض لمدة 3 ايام متتالية واملاح مع فيتامينات وبالخصوص الصغار
تطعيم الحمام سنويا بالتطعيم المناسب لهذا المرض والتركيز على تطعيم الفراخ الصغيرة عند بلوغها 3 اسابيع من العمر ونقلها الى حظيرة خالية من المرض
ملاحظة -هناك علاج آخر متداول بين الهواة وهو ان يبعد الحمام المصاب الى مكان بعيد عن الحمام الغير مصاب وينزع الريش من الرقبة من جانب الالتواء ويطهر المكان بمطهر مع أخذ ابرة نظيفة مطهرة والتقر في المكان المنزوع منه الريش لاخراج الدم الفاسد وبعد انتهاء العملية يوضع مادة مطهرة على الجرح وبودرة مضاد حيوي وتركه في مكان مع ملاحظته واعطائه فيتامينات واملاح مع الغذاء
ونسبة نجاح هذة العملية معقولة جداً
