I'm always on the lookout for probiotics (beneficial bacteria) that can somehow  suppress or dominate Staphylococcus aureus  - because that bacteria is implicated in many illnesses, including sinusitis. Some strains of S. aureus are antibiotic resistant and the cause of serious illnesses, such as MRSA  (Methicillin-resistant Staphylococcus aureus). However, S. aureus is also found in the microbiomes (microbial communities) of healthy people - including on the skin, nose, and gut - but it appears to reside there harmlessly in healthy people.

So finding species of bacteria that suppress or controls S. aureus is noteworthy. Researchers (from National Institute of Health and Thailand) found that in both humans and mice strains of Bacillus, especially B. subtilis, which is already added to many probiotic products, suppressed all strains of S. aureus. Interestingly, the researchers found no S. aureus in any of the gut and nasal samples from humans where Bacillus species were present.The researchers think that the Bacillus species eradicate S. aureus - in both the gut and nasal passages. So the researchers tested further using mice - they gave B. subtilis to the mice every 2 days, and it eliminated S. aureus in the guts of the mice.

But why did I title this post '"another probiotic" ? Because from research and personal experiences told to me - Lactobacillus sakei seems to have the same effect against S. aureus. Stay tuned for more research with B. subtilis and other probiotics versus S. aureus. [UPDATE: Since I posted this, I've read some concerns over B.subtilis. Be careful.]  From Science Daily:
