Research - Natto & Bacillus Subtilis

Here is a really interesting part from MarkyT's link [posted on kickas]. B. Subtilis becomes quite dormant if it is cold.

"Once the good hygienic Germans finally recovered from the shock of seeing the Arab natives gulping down warm camel dung, they quickly realized that there must be something in the dung that somehow counteracted the harmful bacteria that caused the dysentery. They questioned the Arabs, who told them that they had no idea why it worked, but that their fathers had always done so, as had their forefathers and it had always worked. The only caveat was that the camel or horse dung had to be ingested while still warm and fresh, because it had no effect on the dysentery if ingested cold.
So the Nazis began carefully examining fresh camel and horse dung. What they discovered was that it was teeming with a powerful bacterial microorganism which later came to be called Bacillus subtilis. This bacteria, it turned out, is so strong that it practically cannibalizes all harmful microorganisms in the human body-particularly pathogenic bacteria like the virulent strain which was causing dysentery in the German troops."

"According to clinical studies documented in the medical research report, Immunostimulation by Bacillus Subtilis Preparations, by micro-biologist J. Harmann, the cell wall components of ingested Bacillus Subtilis are able to activate nearly all systems of the human immune defense, including the activation of at least three specific antibodies (IgM, IgG and IgA secretion) which are highly effective against many of the harmful viruses, fungi and bacterial pathogens which regularly attempt to invade and infect the human system."
