CORYZA
Is a fast spreading respiratory disease.
symptoms are, sneezing, running nose, note nostrils will clog causing a nasty smell. that is you first warning you have Coryza. sometimes the head and eyes will swell. there may even be a rattle in the throat.
treatment is Sodium Sulfamethazine. 1 tablespoon for each gallon of water for a week to two weeks. note: birds that have been infected could be carriers.
Chronic Respiratory Disease (CRD) is a complex respiratory disease whose root cause is an infection by Mycoplasma Gallisepticum (MG). The MG infection is almost always accompanied with another infection whether, bacterial or viral. The MG infection can be controlled thru medications and vaccinations, however once a bird is infected there is no cure. The secondary infections can be cured thru medication in the case of bacteria or thru the birds immune system, in the case of viral infection. Therefore, as there is no cure for MG the respiratory infections will re-occur with every new bacterial or viral respiratory infection. To add to this complex problem, stress whether it be from a severe change in the weather, poor management, working the bird or whatever, makes the bird more prone to an outbreak.
The signs and symptoms are varied, depending on how severe the infection is, the general health of the bird, what secondary infections are present and how much stress the bird is under. A squeaky crow along with respiratory rattles are usually the first signs. Bubbles in the eyes are very characteristic which can be followed by nasal discharge. Birds, when worked, will be short winded, have very little energy and will become blue headed if the disease is severe. In severe infections the bird will have a fever and will develop diarrhea or the greens and will lose weight.
MG is spread by many means. It is passed thru the egg from one generation to the next. The disease can be carried thru the air for short distances, be carried by wild birds and animals, be transmitted by direct contact or by sharing feed and water cups, and very importantly, by yourself on hands, clothing, or shoes.
Tylan is the drug of choice and will control the disease very well. Tylan can be given by injection or thru the drinking water. LS-50, Spectam, Gallimycin and Tetracycline are also effective. There are live and killed vaccines for the control of MG. The use of live vaccines are controlled in some states and there reactions are sometimes very strong, making live vaccines a second choice to killed vaccines. Killed vaccines offer long term control with very little risk. Also these killed products are now available in combination with Newcastle and Bronchitis, making the 3-way vaccine a broad protection product.
MG which is the cause of CRD, is a problem which must be and can be kept under control. Everyone should know if he is infected so he can control the problem or if he is clean so he can work to stay that way. The only sure way to know your status is by blood testing your birds.
