I am very sorry if I misinterpreted your post. The two organisms you mentioned appear to be very well established strains. They normally do not cause problems in a person with a functioning immune system. Could the taking of the new probiotics and the reappearance of your sypmtoms be a mere coincidence?
I highly recommend checking out the "ask Dr. Stoll website". Read all you can about candida, LGS, bracing, and skilled relaxation. I have come to believe that too much stress plays a major part in many of these difficult to diagnose conditions.
