Nasty family of disease-causing bacteria there (not what I would call a parasite) including syphilis and Lyme disease, both of which must be excluded during differential diagnosis for ME/CFS.
Many people who thought they had ME/CFS discover they have Lyme disease and can be restored to health to a great extent with antibiotics.
Dr. Lipkin is totally on top of all research into the gut biome (viruses and bacteria) as it relates to ME/CFS, I can assure you!
Why is it that you rely on only one authority when it comes to the topic of parasites and health? There are dozens and dozens of PhDs working for decades on this area, that is what I would call “extensive research”.
It is only recently that folks are making the connection between unexplainable chronic fatigue and systemic parasite infestation and impaired immunity. Rather that say parasites are a “cause” of CFS it might be more accurate to say they are a definite factor that many medical practitioners overlook.
If you have time, look at the testimonials on the HumaWorm website. Long time sufferers of CFS are finding that the one area they did not address turns out to be the breakthrough that they have been looking for. It is not to say that changing diet, lifestyle, and other layers are not important, rather, taken all together they form a comprehensive integrative approach to fixing the problem.
