Shannon,
Killing parasites and killing bacteria are two different things. The parasite program, which I have done several times, wasn't designed to kill bacteria. (That's what you use Colloidal Silver to do.) Personally, I have never seen any funky things crawling out of orifices where they don't belong. But I have always felt better after the cleanse.
My suggestion,,,,,keep reading, thinking, go slow. I think your over concerned about the possible results and could be missing a blessing.
