Mes jeunes pigeons ont eu de l'adénovirose, je les ai traités, mais depuis j'ai du mal à les tenir en santé?
answer by: Dr Vincent Schroeder
Vous devez savoir qu'un grand nombre de colonies sont atteintes chaque année par l'adénovirose (également de nombreuses colonies réputées). Or bon nombre des ces pigeons qui on été atteints ont réalisé de super prestations par après. Donc il n'y a en général par de souci pour l'avenir sportif ou pour la reproduction. Le fait de mélanger des pigeons venant de divers colombiers augmente le risque d'adénovirose.
Welk risico lopen nieuw ingebrachte duiven na een voorbije adeno type 2 probleem?
answer by: Ruben Lanckriet
Beste Louis,
Hoewel virussen over het algemeen snel optredende en snel voorbijgaande infecties zijn - dikwijls wel gecompliceerd door secundair bacteriële problemen - is het adenovirus wel een virus dat meestal lange tijd aanwezig blijft. Dit heeft o.a. te maken met de resistentie in de omgeving en de aanwezigheid van virus-dragers. In de omgeving is het virus resistent en dus moeilijk weg te krijgen. Een grondige ontsmetting is nodig om geen virus in de omgeving meer te hebben. De ervaring leert eveneens dat duiven drager kunnen zijn van het adenovirus. Hoewel er een duidelijk verschil is qua ziektebeeld tussen adeno type I en type II, is er geen duidelijk verschil beschreven tussen de virussen zelf. De ervaring op enkele hokken en het feit dat échte adeno type II infecties steeds minder lijken voor te komen in vergelijking met de eerste uitbraken 20 jaar geleden, doen mij vermoeden dat adeno type II waarschijnlijk een agressieve vorm van het 'gewone' adenovirus is dat een infectie veroorzaakt bij oude duiven die relatief weinig immuniteit hebben voor het adenovirus. Ik heb een vermoeden dat duiven die een adeno type I-infectie hebben gekregen als jonge duif een levenslange immuniteit hebben, ook voor adeno type II.
Voor de nieuw ingebrachte duiven is dus mijns inziens ook de immuniteitsstatus van belang. Het kan gerust zijn dat je bij inbreng van deze duiven geen enkel probleem zal zien, maar dat ze toch geïnfecteerd worden met het virus zonder weliswaar ziek te worden.

All pigoens looked fine this morning but when I got home after work 1 young bird was dead on the floor?
answer by: Ruben Lanckriet
Dear Andy,
This could have multiple causes. An ordinary trauma f.e. flying wrongly with his neck against something could typically give this sudden death, but a disease like the adeno-coli syndrom could also cause this. An autopsy could be of great help.
Kind regards
E coli what is the best treatment for this and how often to treat to stop it coming back?
answer by: Ruben Lanckriet
Dear Mike,
It is important to realise that E. coli is a normal intestinal bacteria that is part of the normal flora of every healthy pigeon/animal/human. Certain E. coli strains can sometimes give problems mostly in association with other infectious problems like f.e. adenovirus. Some E. coli strains are more pathogenic than others and can give coli-septicaemia, meaning the bacteria manages to get into the bloodstream and organs, giving inflammations and serious illness. In some species these E. coli strains are called enterohaemorhagic (because they can also give bloody diarrhea) or EHEC. Most E. coli strains, however, are relatively harmless. A big problem with E. coli, though, if it does give a problem, is the very frequent antibiotic resistance. This is because of the massive overmedication, certainly also with pigeons. A lot of fanciers tend to give frequent medication for respiratory or other diseases, using all kinds of the existing antibiotics. Because there are always E. coli strains in the intestines, these bacteria strains develop resistance against these antibiotics, and so we are seeing that a lot of antibiotics aren't working anymore. A good example of this is enrofloxacine or Baytril.
My advice would be to only treat when there is really a problem and let make an antibiogram by samples taken by your veterinarian. An antibiogram is a test that determines what antibiotics still work for an antibiotic strain. For E. coli this is very much needed. It is very difficult to predict what antibiotic could still work. If you are not able to test the strain with antibiogram, it could be wise to use antibiotics that you do not use a lot and follow the advice of your veterinarian.
Never give antibiotics to pigeons if there is no problem at all. That is a waste of product.
Kind regards
My 6 pigeons died without giving me any symptom. First thing is they didn't eat, and if i feed them some of them vomit?
answer by: Ruben Lanckriet
Dear Madam/Sir,
My first suspicion is a problem with adenovirus, but there is not enough information on age of the birds and findings on veterinary examinations. So i cannot exclude other causes like paramyxo, paratyphus, parasites, etc..
Kind regards
Some of my pigeons are losing weight, they don't eat and they throwing up white water?
answer by: Ruben Lanckriet
Dear Madam/Sir,
This seems to be a typical case of adenovirus type I mostly complexed with E. coli and hexamitiasis. An antibiotic treatment for these problems combined with light digestable food (not much) and liver protection, is usually enough to get them better.
Kind regards
my pigeons have a problem of vomiting. Whenever they eat any food they vomit so they got very weak?
answer by: Ruben Lanckriet
Dear Madam/Sir,
The symptoms you are describing are indicative for an adenovirus type I problem complexed with E. coli or hexamita, if the birds you are talking about are of young age. It could be wise to treat your birds for this disease (antibiotics) in accordance with your veterinarian and let the birds be examined to exclude other causes that could complex the problem. If the problems are occuring with old pigeons, there could be a problem with adenovirus type II, candida, herpes and/or trichomoniasis.
Kind regards
My pigeons have a problem of vomiting, not eating and then dying?
answer by: Ruben Lanckriet
Dear Sir,
From the symptoms you describe this could be adenovirus, but a medical examination should be necessary to exclude all other causes. You can treat the birds for secundary bacterial infections like E. coli. These are antibiotics like trimetoprim, amoxicilline, doxycycline, lincomycine, enrofloxacine,... An antibiogram can be of help to determine the right medication.
Kind regards
Après une infection de type adeno j' ai effectué les traitement appropriés mais je n arrive pas a retablir la flore intestinale?
answer by: Vincent Schroeder
Monsieur,
Je ne crois pas en une flore digestive très développée chez le pigeon (contrairement aux humains par exemple).
Si vous voulez signifier que les fientes ne sont pas encore parfaites en disant que vous ne savez pas rétablir la flore intestinale, il faudrait voir si les fientes sont aqueuses ou collantes (grasses). Il faudrait faire effectuer une analyse de fientes par un vétérinaire spécialisé pour écarter toutes pathologies (coccidiose, vers, paramyxo, paratyphose, mycoses...). Seulement après cela l'on peut déterminer le meilleur traitement possible.

Pigeon found very ill with yellow runny droppings. Refuses to eat or drink. What medicine to give and at what dose?
answer by: Ruben Lanckriet
Dear Madam/Sir,
The symptoms indicate a very severe liver damage. It could very well be this pigeon is infected with adenovirus type II, but a diagnosis can only be given through inspection and examination by an (avian) vet. If it is adenovirus II, this pigeon is lost and cannot be treated. All birds that get ill from this disease, also die (100% mortality).
For other causes a veterinary examination of the bird is necessary.
Kind regards
My this years young birds have come down with a serious case of young bird sickness?
answer by: Ruben Lanckriet
Dear Sir,
Young bird sickness is caused by an adenovirus typical for pigeons (type I). This virus primary causes dammage to the liver and intestines. The liver and intestinal inflammation causes diarrhoea. The hepatitis causes also the vomiting and the not digesting of food. In a lot of cases other agents such as Escherichia coli (a bacteria) or hexamita (protozoön) takes advantage of the situation and causes more intestinal inflammation and diarrhoea. E. coli is normally present in the intestines of ALL pigeons. There is no such thing as getting rid of E. coli. This is the same for other bacteria like staphylococs, streptococs, etc... There is no treatment against the adenovirus although I have seen that pigeons vaccinated for paratyphus are less susceptible for the disease (and all kinds of diseases). Off course you can treat for the secundary infections (treatment for E. coli and hexamita) after clinical examination of the birds and exclusion of other possible infections. If the antibiotics do not help, it could be wise to do an antibiogram of the E. coli as there is a tremendous antibiotic resistance rate in E. coli. At the same time it is wise to give light digestible food and perhaps also a liver protection like sedochol, biochol or...
Kind regards
My pigeon is about 3 months old and I started training him 2 weeks ago. last week I noticed him vomitting after it ate?
answer by: Ruben Lanckriet
Dear Madam/Sir,
This is indeed most probably adenovirus type I. A bird can have a good appetite a while after it has vomitted.
Other causes for vomiting can be trichomoniasis, candidiasis (, herpes).
Kind regards
my young pigeons have jelly droppings and still have food in their crops in the morning and they look terrible. Can you help me?
answer by: Ruben Lanckriet
Dear Madam/Sir,
This is probably an indication of an adenovirus infection or young bird sickness. Other possibilities could be trichomoniasis, candidiasis, herpes. Adenovirus attacks the liver and so can be the cause of bad droppings, vomiting, nausea. Usually E. coli or hexamita takes advantage of the situation and causes enteritis. That's why the treatment is mostly directed to these secundary infections. I also always give a liver protection like f.e. sedochol with the treatment.
Kind regards
My pigeons have young bird disease. What is the best natural treatment for this disease?
answer by: Ruben Lanckriet
Dear Madam/Sir,
As natural treatment you should certainly give liver protection - f.e. sedochol, biochol, or... - . As a natural antibiotic you could give garlic and/or a herbal tea.
Kind regards
My birds are dying without other clear symptoms?
answer by: Pascal Lanneau
Dear Sir,
To diagnose your problem, I would recommend to do a necropsy on a dead pigeon, because without a good diagnosis, it is impossible to treat like it should be.
Death can be caused by many different agents, such as adeno type II, Coli, Paratyphus, eating of toxic materials, etc….
I would surely recommend to test the droppings, checking the presence of wurms, coccidiosis, also to do a culture of a 5 day droppings, searching for paratyphus.
A vet can may be diagnose something on a living pigeon also, tricho,…

Mijn doffers vermageren en vertonen dunne gelige mest?
answer by: Ruben Lanckriet
Beste Sebastiaan,
De gelige kleur van de mest duidt op een leverprobleem. In het ergste geval hebt u te maken met adenovirose type 2 wat een zeer ernstig verloop met sterfte kan geven. Ik raad u aan een dierenarts te raadplegen voor verdere onderzoeken.
Sportieve groeten
Once the young pigeons reach 20 days old they vomit , no appetite, lameness and they die?
answer by: Ruben Lanckriet
Dear Sir,
I cannot make a diagnosis without seeing birds and taking samples, but I can give you some information what possible diseases could give the problems you are seeing with your birds.
As possible diseases I'm thinking of paratyphus, trichomoniasis and adeno virus. There is a big chance the birds are also infected with circo virus and therefore lack the immunity to cope with diseases. You can find more information on these diseases by clicking on the corresponding tags. Let your birds be examined by an avian vet to get a correct diagnosis.
Kind regards
My young birds are detoriating, symtoms are losing weight and light green (fresh leave color) watery dropping?
answer by: Ruben Lanckriet
Dear Madam/Sir,
A diagnostic examination of the birds by a veterinarian is important. With the symptoms you describe, there are some possibilities. It is important to know if there is/was any vomiting, problems flying or nervous problem. From the info I have from you I think mainly of adenovirus, paratyphus, endoparasites, perhaps paramyxovirus, streptococcus or another infection. There is also a possibility the young birds are weakened by the circovirus so any infection can cause severe problems, as this virus takes away the pigeon's immunity.
Kind regards
Hi, my brother has a pigeon that is about 1yr 6 months. The pigeon started vomiting and also having yellow droppings?
answer by: Ruben Lanckriet
Dear Madam/Sir,
It is very possible the pigeon has the adenovirus type II. This is a very serious illness that causes complete destruction of the liver and death of the pigeon. It is very important you get the bird into quarantine and desinfect the lofts completely.
The bird will normally die if it is this virus. If there is another (bacterial) cause for these symptoms you can give the bird antibiotics, sedochol and electrolytes, if necessary by injection by your veterinarian. A clinical examination is always of help.
Kind regards
Is there any adenovirus and herpesvirus vaccines available for pigeons? Can we use circovirus and pox vaccines for chickens?
answer by: Ruben Lanckriet
Dear Sir,
There are no such pigeon vaccines available at the moment. The EDS vaccine for chickens has been used with pigeons for adenovirus, but scientifically the efficacity of this is seriously questioned, because the EDS adenovirus is very different to the pigeon adenovirus. The problem with vaccines developed for other animals is that these vaccines are not tested with pigeons for efficacity or side-effects. Sometimes the virus strains can differ a lot from the virus strain that causes disease with pigeons. It could be interesting to test the chicken circo vaccines on pigeons. I don't think it is interesting to use the Marek vaccines (herpes) for chickens, because the virus is quite different.
It is absolutely not advisable to use chicken pox vaccines with pigeons. In some chicken vaccines the original (living) pigeon pox virus is used. This means you would give your birds the pox disease.
Kind regards
This morning when feeding my pigeons i noticed one pigeon sitting on the perch whith its eye lids half closed?
answer by: Ruben Lanckriet
Dear Sir,
The symptoms are those of a very sick pigeons with a real chance of dying soon. The yellow urine is indicative for a severe liver problem f.e. adenovirus type 2 can do this. I advise you to let the bird(s) be examined by a veterinarian if possible and let take samples to get a good diagnosis. If you have a sick pigeon it is always advisable to put this bird in quarantine to protect the rest of your colony.
Kind regards
Welke zijn de gevolgen bij duiven die (zwaar) besmet geraakten met het :- herpesvirus - paramyxovirus - adenovirus?
answer by: Ruben Lanckriet
Beste,
De gevolgen kunnen min of meer groot zijn ngl. de graad van besmetting. Uw vermoeden is terecht dat dit vaak onderschat wordt. Voor de verschillende aandoeningen die u aanhaalt, zijn de gevolgen wel verschillend. Ik dien ook op te merken dat de graad van ernst van ziekte bij jonge duiven heel dikwijls sterk afhangt van de aanwezigheid van circovirus en de schade die dit virus aanricht aan het immuunsysteem (vernietigen van de zogenaamde B-cellen, dit zijn de cellen die instaan voor de aanmaak van antistoffen).
- Het herpesvirus kan zorgen voor een ernstige aantasting van voornamelijk de lever bij jonge duiven tot de leeftijd van 4 maanden. Hoewel lever in staat is te regenereren, kan men zich terecht afvragen of een duif die ernstig aangetast geweest is als jonge duif nog wel in staat is dezelfde stofwisselingscapaciteit te genereren. De lever is de stofwisselingsfabriek bij uitstek en voert heel wat nuttige functies uit tijdens een inspanning zoals een wedstrijdvlucht. Zeker als de afstand van een duivenvlucht groter wordt, is een duif die niet meer de volle 100% levercapaciteit bezit, in het nadeel. Het kan zelfs mijns inziens het verschil betekenen tussen al dan niet terug thuis geraken. Uit de praktijk is dit ook gebleken bij duiven die ooit als jonge duif vergiftigd geweest zijn met leverschade. Dit is ook logisch aangezien de lever zowel energie kan opslaan onder de vorm van vet en glycogeen, als tijdens een vlucht stoffen kan 'recycleren' met vrijkomen van nieuwe energie (dit is bijv. het geval met melkzuur waaruit opnieuw glucose gevormd wordt in de lever). Een duif die slechts 90% levercapaciteit bezit, kan onmogelijk hetzelfde prestatieniveau bereiken op grotere afstanden in vergelijking met een duif met 100% levercapaciteit. Naar kweek toe ben ik van mening dat die invloed veel geringer is m.a.w. voor de kweek zijn deze duiven mijns inziens wel nog volwaardig inzetbaar.
- Het paramyxovirus is een andere zaak. Dit virus zal voornamelijk de nieren en zenuwen gaan aantasten. Hoewel de invloed verschillend is, is deze daarom niet minder gering. Het spreekt vanzelf dat een duif met een lagere niercapaciteit soms ook minder zal presteren. Zolang de nierschade binnen de perken is gebleven, kan dit nog meevallen, maar opnieuw zullen grotere afstanden meer problemen geven. Bij een langdurige inspanning gaan er water en electrolyten verloren, bij slecht werkende nieren nog meer. Zo'n duif zal dus sneller water en electrolyten nodig hebben. Indien de zenuwen aangetast waren, kan het soms een hele tijd duren vooraleer de zenuwsymptomen verdwijnen (tot maanden). Eenmaal de zenuwsymptomen verdwenen zijn, is deze duif volledig hersteld -op gebied van zenuwstelsel weliswaar-. De reden van dit traag herstel heeft te maken met de trage regeneratiecapaciteit van een zenuw. Zolang het zenuwcellichaam niet aangetast is, kan een zenuw teruggroeien, maar dit verloopt wel zeer traag. Naar kweek toe heeft het ooit aangetast geweest zijn met paramyxovirus heel weinig nadeel. Naar wedstrijden toe heb ik sterk mijn twijfels.
- Het adenovirus is in feite hetzelfde verhaal als voor herpes. Ook hier kan een ernstige leveraantasting gebeurd zijn en ook hier kan een duif daar levenslang de gevolgen van meedragen. Ik ben eveneens van mening dat de invloed op wedstrijden veel groter is dan op kweekcapaciteit. Bij adenovirose kan er naast de leveraantasting ook een darmaantasting gebeurd zijn. Ik denk persoonlijk dat de invloed van deze darmaantasting veel geringer is voor latere prestaties dan de leveraantasting, omdat darm zeer snel kan regenereren.
Met vriendelijke groeten
The birds drink water and the water stays in the crop. The birds crop swells and the bird will die. Could you advise?
answer by: Ruben Lanckriet
Dear Madam / Sir,
This could be adenovirus, canker and/or a yeast infection. Best is to let the birds check for these parasites and do an appropriate treatment. The adeno-coli syndrom can be treated with antibiotics, sedochol, electrolytes, light digestable food. Canker with nitro-imidazoles and yeastinfections with amphotericin B or nystatine (depending on the kind of fungus). Kind regards
My birds have been dying and had diarrhoea from an unknown disease?
answer by: Ruben Lanckriet
Dear Sir, Some of the symptoms are indeed indicative for paramyxo virus. Nevertheless, as you mentioned yellow diarrhoea with birds before they die, I also suspect adenovirus type II. Yellow diarrhoea is a sign the liver is very badly harmed and that's the case with adenovirus type II. The virus even completely destroys the liver. With adenovirus II, there is 100% mortality, this means that if a bird gets sick it will certainly die. Luckely not all the birds get sick. It is not clear why one bird gets sick and the other not. The fact that sick birds also could survive on your loft, indicates adenovirus type II can't be the only problem. It is very possible that the watery dropping are caused by the hairworm infestation and/or paramyxo. The bad feathers could be an indication the young birds are also infected with circovirus. This virus attacks immune cells of the young bird (under 4 months old), this makes them vulnerable for all kinds of infections. It is a major problem this year in Belgium with a lot of deaths in young birds. They can die from ordinary infections like canker, but also from paratyphoid, adenovirus, etc... Certainly do not underestimate the hairworm infestation as it can also be cause of deaths. As for the vaccination for paramyxo, it is advisable to also do this as soon as possible. Kind regards
Hi, I have 3 stock birds which went sick. They are having very liqiud faeces which smell very bad. Baytril doesn't help.
answer by: Ruben Lanckriet
Dear Sir,
You should consult a vet as soon as possible. There are some possibilities for the symptoms. One of the possibilities certainly could be paramyxovirus, in which case your other birds also could be in danger.
Other possibilities are parasites, adenovirus type II, yeast infection, etc.
Kind regards
