Here's a quotation from that web site:

"You may very well be infected with a stealth bacterium that initially
produces no symptoms, cannot be detected by conventional testing, and
may produce illness in different organs of the body years or decades
after first infection, thus eluding its identification as a master
underlying cause of disease."

This is the exact same nonsense that is claimed for HIV - the virus
nobody can find, nobody can determine how it kills (many years later,
even though there is often the same amount of viral activity), and
against which a billion-dollar industry has been established.

The mechanism for all of these maladies is the same, with the exception
of getting a large dose of a nasy strain of a pathogen, and that
mechanism is stress, usually oxidative stress, which kills off immune
system cells as well as suppresses the organs that generate those
cells.  Anyone who tells you that a "crazy prion," a retrovirus, or a
bacterium is going to kill you decades later is living a fantasy.  Your
body can withstand anything that doesn't kill quickly (or do physical
damage that leads to a biochemical cascade that can kill, as in blunt
force trauma), but you have to eat right, get enough sleep, etc.
