Is a spirochete a parasite?
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!
