When I was dealing with a possible outbreak of MG, Kathyinmo and I were PMing information back and forth. This is one of the PMs that Kathy sent me. It was from a thread here. I can't remember the exact thread name. I use Denagard now on a monthly basis. Eggs and chicks "should" be MG free. I have not had any tested, but, since starting the prevention program, I haven't had any symptoms.

...they have CRD, Chronic Respiratory Disease, caused by Mycoplasma bacteria that is considered to be one of the smallest cell bacteria that has no walls, where no antibiotic will cure and then it acts like a virus, only rearing its ugly head when your birds are stressed, over heated, cold, or during molt. I was hoping I could successfully treat them with two antibiotics, terramycin and streptomycin, but within the last two days they have started to show mucus around the nostrils and as of today, one has reverted to a pneumonia like symptoms, coughing, gurgling, swollen face and frothy eyes.
From a very recent post on another website "I also found the articles about Mycoplasma interesting, as he talks about Tiammutin (Denagard) as an effective treatment
Mycoplasma is present in 75% - 89% of ALL flocks, both commercial and private according to Dr. Scott Jones at the Baron Diagnostic Lab in Wisconsin. If you have bought birds from somewhere else or birds were previously raised on your property, it is highly likely that you have Mycoplasma in your birds. Most people never know it, as symptoms usually do not appear unless the flock is under stress. Common symptoms are decrease in egg production, also embyo and chick mortality (Mycoplasma can be transmitted via egg). Mycoplasma It is extremely hard to treat but Tiamulin (sold as Denagard) is a very effective antibiotic, especially against bacterial respiratory diseases. Denagard has the added advantage of having zero withdrawal period for eggs as it is unrelated to any antibiotic used in humans. You can read more about it here:
I ordered it from QC Supply. http://www.qcsupply.com/
I keep it on hand as an effective broad spectrum antibiotic that is available without Rx. It can also be used as a preventative against Mycoplasma. Dosage instructions;
Preventative is 8cc's to a gallon of water
Treatment is almost double the preventative dosage, 15cc's to a gallon of water.
Give as only water for 3-5 days, repeat in 3 weeks
If breeding for chicks with your birds, I would do the treatment dosage for the 5 days, then again in 3 weeks reduce dosage to 12cc per gallon. (Denagard given to breeding hens prevents transmission via egg)
Don't exceed the 15cc's to a gallon of water, it can harm kidneys. Denagard is bitter, if your birds wont drink it add a bit of sugar to the water
Make sure you are not using medicated feeds. Chick starter with Amprolium in it IS SAFE to use with the Denagard, the Tiamutin site lists the drugs that are safe to use with it. You dont want to use other antibiotics at the same time as antibiotics can be hard on the birds kidneys"
I've since read up on it; sounds very promising. And note that it is a bacteriacide.
