was there any mention of the exact strain of B. subtilis that they tested? i couldn’t find it. not every strain of B. subtilis produces fengycinResearch in Thailand found that people with the Bacillus bacterium in their gut never seem to have Staphylococcus in their intestines or nasopharynx.
Thai researchers tested 200 healthy people, and they found that when Bacillus was present in their gut, then Staphylococcus was always absent. So it seems that these two bacteria cannot exist together.
The researchers think this because Bacillus bacteria secrete substances called fengycins which disrupt the Staphylococcus life cycle, and so kill off the Staphylococcus.
The study indicates that taking a Bacillus probiotic might be able to eliminate Staphylococcus from the gut and nose. To quote the study:
So over the last two weeks or so, I've been taking Bacillus subtilis as a probiotic, as well as spraying a solution of Bacillus subtilis into my nose (the latter is possibly risky, although a Bacillus bacteria nasal spray was tested in a human study).
So far with my Bacillus probiotic treatments, my IBS seems to have improved, and I think my energy levels are increasing a little.
I have Staphylococcus in my gut, as tested by a Genova Diagnostics stool analysis, so potentially I may have Staphylococcus issues involved with my ME/CFS.
Prof Gottfries's great success in treating ME/CFS using a Staphylococcus vaccine (see this post) suggests that Staphylococcus may be driving ME/CFS in many patients.
I bought the SuperSmart Bacillus subtilis probiotic from Amazon.
You also obtain a Bacillus coagulans probiotic. And some Bacillus probiotic products contain both Bacillus subtilis and Bacillus coagulans together.
Note that Bacillus subtilis is a spore-forming bacterium, so is hardier than your average probiotic.
To make my Bacillus subtilis probiotic more effective, I dipped the capsules into a shellac solution, applying 3 coats of shellac to the outside of the capsules. Shellac is acid resistant, and this coating is used in the pharma industry to make enteric capsule (capsules able to survive stomach acids).
Shellac solution can be easily bought as a confectionary glaze (it is used to make food items like chocolate shiny).
