Notice, the part where they go into "cyst form", is after he put pencillin with them :( That's what happens with Antibiotics . You can also see why a "Lyme colony" could feel like a big parasite.
EDIT- this is a better video, showing more of the life cycle, colonies, and cyst form. BTW..I didn't know that Royal Rife was who invented the dark field microscope until recently. http://www.youtube.com/user/lymebug#p/a/u/0/vpKtC1H5fhc
I have to look for the other ones- the one where the spirochete blows up the blood cell is especially interesting.
