Trying one more time to post. I just don't think this forum likes me.
The big question is do you actually have bartonella or do you have the mystery bug which is most likely a protozoa?
If you are relying on a Fry slide to disgnose bartonella then you probably have the protozoa instead -- visually these pathogens look alike on a bloodslide. If you have an antibody test which is positive then you probably do have bartonella.
The treatment would be very different depending on the pathogen. The protozoa responds to some antimalaria drugs and herbs or toxoplasmosis meds supposedly.
