Help please........
This past summer I had some birds get sick that had loose dropping and some would have vertigo real bad, could not fly or stand?
Of course I did not know what to do so I ordered 4 in 1 and treated all my birds and killed all that showed symptoms. After 4 in 1 I put them on probotics & pigeon builder.
Well, things were fine for about 3 months and this morning I went out to the loft and I have a young kit birds that can not hardly stand up as he has vertigo.... He feels great/healthy in the hand....
At this point I am totally frustrated... Between the BOPs, cats & now this sickness it is disheartening.
Any ideas/help would be greatly appreciated....

read about pigeon ataxia in the article. caused by PMV or salmonella. Not sure the life span on PMV, but its possible, it may have been latent and some how the birds got reinoculated with it and are coming down with it. Isolate immediately.

read this as well. I cant help any more as I have no personal experience with your situation.
Pigeon Paramyxovirus-1: Pigeon PMV-1 is mesogenic to poultry but causes severe neurologic disease in pigeons. Transmission is by direct contact or by inhalation of fecal material or respiratory secretions, and through pigeons flies.6,10,14 Clinical signs include polyuria and polydipsia and watery or bloody diarrhea.4,12 The experimental incubation period is 5-18 days. The first clinical signs of infection are polydipsia and polyuria in 20-70% of unvaccinated birds.3 Mortality is highest in young birds and may approach 90% PMV-1 epornitics are often seen with underlying circovirus problems.6 Respiratory signs are uncommon with pigeon PMV-1, unlike with NDV. Neurologic signs include torticollis, ataxia, faulty perch landing, and inability to prehend food.5,7,21,23 Many birds may be slightly lethargic and polyuric and spontaneously recover.14 Necropsy findings include pulmonary and hepatosplenic congestion, as well as non-suppurative pancreatitis and encephalitis.6,14 Sick birds should not be returned to the flock until 6-8 weeks after recovery.12,14 Older birds can recover within several weeks. Severely affected birds may take longer to recover. Shedding may continue for longer than a month. However, recovered birds are not considered latently infected.12 Birds returning from a race or show should be quarantined for a minimum of 6 weeks. Blood samples can be collected and submitted for PMV-1 serology.6 A four-fold increase in titer indicates active infection. In the United Kingdom, pigeon PMV-1 is a reportable disease.14 Vaccination prevents disease but does not prevent infection or viral shedding.12,14 Subcutaneous vaccination is recommended, along the lower third of the neck on the midline. The only licensed and approved PMV-1 vaccine available in the United States is an inactivated, oil emulsion vaccine (Lohmann Animal Health International). It is administered subcutaneously along the caudal neck or inguinal web. Inappropriate vaccination may lead to injection site granuloma formation. All new pigeons should be vaccinated during quarantine and adults should be vaccinated 6-8 weeks before a race or show.5 Older, unvaccinated birds should be dosed twice, 4-8 weeks apart. A single booster is administered annually. Squab should be vaccinated at 3-4 weeks of age with a second dose administered 4-8 weeks later.14 All birds, young and old, should be vaccinated at about 2 weeks before the breeding season.3 If birds are breeding over the winter, they can be vaccinated while sitting on eggs, but there may be reduced maternal antibodies.3 Because vaccinates may still shed virus, they should not be housed with naive birds.6 Vaccination during an outbreak may reduce morbidity and mortality.4,5 Vaccination with NDV strains does not provide adequate protective immunity and is strongly discouraged. In Europe, vaccination against PMV-1 is legally required for racing and show pigeons.12

You must vacinate for pmv and follow with a boster and revacinate few months later.

More than likely not PMV. I say this because it is such a contagious virus that you would have had heavy casualties had you had it in your loft. You need to look around your lofts for signs of rats and mice. Sounds to me like you have a case of paratyphoid. Joe

Rick,
Thank you, my birds have grit all the time as I feed grain. thank you...
J.M.Urbon,
Do you treat paratyphoid with a sulfa drug? Is that why it went away after I treated with 4 in 1?

Yes a good 4&1 or 5&1 will work you need to follow the treatment for the time recommended though. Also like I said earlier you need to lok for any signs of rodents. They are the #1 cause for paratyphoid. Also you should know that some adult birds never do get rid of it and will always be carriers. The will need to be identified and disposed of or you will continually have it popping up with their young. Joe
PS I might also add that you dont want to treat with any drugs especially sulfer based drugs unless you have probable cause. The sulfer based drugs are hard on the liver and repeated use will also cause the drug to loose its effect. Always follow up with some type of health bacteria such as probiotic. Joe

J.M.Urbon,
Thank you, I have decided to cull all the ones I think may or may not have it.
I have also put out some mice/rats, I have not seen any evidence of them; however, that does not mean anything. hopefully they will take the bait...

PEOPLE - Stop posting that a person has PMV every time someone says they have sick birds. Running your mouths about things you have no idea of makes things worse and usually massively over-complicates the issue.
Richard, one of the most common sicknesses in pigeons is parathyphoid which can affect all parts of the body, including the nervous system. When it attacks the nervous system they show all kinds of goofy signs like twisting necks or shaking heads, unbalanced walking, etc. If they clearly walk or scoot backwards, that is one sign of PMV, but only clinical tests would reveal it.
Another highly common sickness is circovirus which vets state that most lofts have come in contact with at one point or another. Circovirus is like aids to pigeons, it shuts down their immune system and they get sick from whatever they are harboring or come in contact with. This could be parathyphoid or any number of things.
Parathyphoid is best treated with Baytril. Ammoxicillin is another often good one to use. Some strains respond well to cephalexin. Only a lab test will reveal which medicine the bacteria responds to the best. 4-1 is not a good anti-parathyphoid medicine.

Circoviruses are the smallest pathogenic DNA viruses that have been isolated. Other circoviruses include porcine circovirus, chicken anemia virus, and psittacine beak and feather virus. Pigeon circovirus and PBFD are related but distinct viruses. Short and long psittacine probes will not hybridize at high stringency but the long probe will hybridize at reduced stringency.14 Affected species include homing pigeons and Senegal doves (Streptopelia senegalensis).15 Infection in pigeons has been documented worldwide. Circovirus infects young pigeons prior to bursal involution, and the bursa may be the route of entry of the virus into the host. Mortality may be limited to young birds.6 Inclusions have been observed in pigeons from 4 weeks to 1 year of age. Vertical transmission may be possible. Circovirus infection causes severe immunosuppression and secondary infections are very common.4,15 Clinical signs in pigeons are similar to those in psittacines, although feather dystrophy is rarely documented. Loft infections are highly variable but may manifest with a high morbidity and low mortality. Clinical signs in racing pigeons include poor racing performance, diarrhea, and signs related to secondary infections. Severity of clinical signs is dependent upon the age of the bird and extent of secondary opportunistic agents. Infection of Senegal doves has only been reported in Australia, with feather loss and dystrophy being the only clinical signs.15 Diagnosis can be made by bursal biopsy or necropsy with histopathology and identification of inclusions. At least one company (BioBest Laboratories Ltd, Penicuik, Scotland) offers a commercially available PCR test on liver and gut contents for PiCV. Lack of adequate response to vaccinate suggests inadequate humoral immunity in infected birds.14 Treatment is supportive and aimed at screening and treating for concurrent infectious agents.6 Spontaneous clinical recovery has been observed. Disinfection, population control, and halting of breeding for 1 year may not alter the course of disease.6
CLINICAL SIGNS
- lethargy, anorexia, diarrhoea, decreased growth
- numerous secondary diseases are seen
- poor response to vaccination
- feather disorders rare – in the 1 case seen, lesions were similar to parrots
- horizontal transmission – inhalation/ingestion
- Histological evidence has been seen in 1 day old chicks, suggesting vertical transmission?
- inclusion bodies seen in cloacal bursa
- Also seen in Senegal Doves in WA.
- Feather dystrophy seen
I say, read about all possible illnesses, match up your clinical signs and do your best. Or find a vet that will work on your birds and give you anwswers.
How did the bird turn out.

The best-known symptoms are swollen wing and leg joints ("boils"), which should be considered almost pathognomonic by the practitioner when observed. Most pigeons with paratyphoid present with an array of other symptoms, however, including anorexia, weight loss, ruffled feathers, dropped wings, refusal to fly, diarrhea, green droppings, reproductive problems such as embryonic or early squab death, or death of older birds.
I would like to gamble that people want to point to PMV because neurological signs is the best known symptom, not so much with the other ones.

Thank you all for the input as I have basically now did everything recommended.
I have culled all of the birds I frlt at most risk, I hate to do it; however, I needed to consider the health of the overall flock... I have ordered some antibiotics which I have never used and that maybe why I have a problem.
I plan on following that up with probotics & pigeon builder....
I have made some hard decisions and I am now looking forward...
Thanks again,
Richard
