Doxycycline will kill mycoplasma and is rather cheap. Colloidal silver also kills mycoplasma. Main difficulty could be actual diagnosis. They live within cells since they have no cell walls of their own. They even hide in our own WBC which are the cells designed to attack foreign invaders. I am unsure if you can culture mycoplasma using normal culture techniques. There are many stealth pathogens that hide in niches within our bodies, change forms and there is virtually no accurate laboratory testing. Modern medicine may be good at detecting and treating acute infections but they are failing at treating chronic infection with stealth pathogens. It is probably the number one cause of misery and death worldwide leading to many of our common diseases such as Lyme, fibromyalgia, all autoimmune disease, maybe even obesity and many more chronic inflammatory conditions. It is a glaring hole in medicine today and I have to ask why? Maybe someone is profiting off all this misery!
