Bacillus Subtilis Probiotic Greatly Reduces Staphylococcus Levels
A 2019 study from Thailand found that people with the Bacillus bacterium in their gut never seem to have Staphylococcus in their intestines or nasopharynx. See the article here.
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 believe this because many Bacillus bacteria secrete substances called fengycins which disrupt the Staphylococcus life cycle, and so kill off the Staphylococcus.
EDIT 2023: Then in a later 2023 study, these researchers demonstrated that the oral Bacillus subtilis probiotic (MB40 strain) for 30 days greatly reduces Staphylococcus populations in the gut, and to a lesser extent also reduces Staphylococcus levels in the nose.
Staphylococcus levels in the gut were reduced by 96.8%, which corresponds to a 31-fold reduction. In the nose, Staphylococcus levels were reduced by 65.4%, which translates to nearly a 3-fold reduction.
This study used the OPTI-BIOME Bacillus subtilis MB40 probiotic from BIO-CAT Microbials.
Possible Rationale for Using a Bacillus Subtilis Probiotic to Treat ME/CFS
The reason reducing Staphylococcus levels might ameliorate ME/CFS relates to the ME/CFS therapy created by Professor Carl-Gerhard Gottfries in Sweden: he used a Staphylococcus vaccine to treat ME/CFS with great success, allowing many ME/CFS patients to return to work (see this post). This suggests that Staphylococcus may underpin ME/CFS in many patients.
My Test With Bacillus Subtilis Probiotic
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.
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.
EDIT 2023: I took the wrong probiotic! It is only the Bacillus subtilis HU58 or MB40 strains which secrete the fengycins protein which kills Staphylococcus. The Bacillus subtilis I took was not one of these strains, so I don't think it will secrete fengycins. So my results can be discounted.
Bacillus Subtilis Probiotic Sources
Important: most Bacillus subtilis probiotics do not produce fengycins, so will not be able to fight Staphylococcus. I don't think the SuperSmart brand I bought is able to synthesise fengycins. To kill off Staphylococcus, Bacillus subtilis HU58 or Bacillus subtilis MB40 must be used (MB40 is also referred to as ATCC 122264).
Note that the BS50 strain of Bacillus subtilis may also secrete fengycin, according this study:
➤ Microbiome Labs HU58 Probiotic (also here for £54) contains Bacillus subtilis HU58, 60 capsules at 5 billion CFU per capsule.
➤ Youth & Earth Spore Probiotic £33 contains Bacillus subtilis HU58, 60 capsules at 4 billion CFU per capsule.
➤ BacilloSpore Select Probiotic $50 (also here for £50) contains OPTI-BIOME Bacillus subtilis BS50, 100 capsules of 1.5 billion CFU per capsule.
➤ Ameo Life Probiotic contains Bacillus subtilis MB40, 60 capsules for $43. But it is not clear how much. Each capsule contains 7.5 billion CFU of Bacillus subtilis MB40 + Bacillus coagulans.

Note that the BS50 strain of Bacillus subtilis may also secrete fengycin, according this study:
a few secondary metabolites (e.g., bacillibactin and fengycin) that are synthesized by non-ribosomal peptide synthases (NRPS) were predicted to be produced by BS50
