So if you put an arterial plaque under a microscope you will see it is full of dead spirochetes?
It's harder to do than that. Spirochetes are hard enough to see when they are alive. You have to have a phase contrast microscope to see them. . . they are almost transparent to begin with. They they look like long wires in a spiral. When alive, the are spotted because they move rapidly.
Take a look at the videos in the first post I made above.
But, yes, that is exactly what they find. . . along with a lot of other crud.
