Staphylococcus aureus is a gram positive bacteria that is a member of the Firmicutes phylum. It is found in 30% of the human population. It is often commensal but can sometimes causes disease, including infections of the skin and endocarditis. It also commonly colonizes the human gut.[1][2][3] and can also colonize the nose.[4][5]


Possible biochemical effects[edit | edit source]

S. aureus produce coagulase, an enzyme that causes blood clotting.

The presence of S. aureus in a model of the human gut decreased the production of butyrate.[6]

Staphyloccocus bacteria produce alpha toxin[7]

In chronic disease[edit | edit source]

Higher levels of S. aureus was found in the mouths of patients with Sjogren's syndrome.[8]. A higher prevalence was also found in patients with irritable bowel syndrome,[9] and is implicated in traumatic brain injury.[10]

Probiotics[edit | edit source]

Several probiotics were found to reduce adhesion of S. aureus to the human gut including Lactobacillus rhamnosus GG, Lactococcus lactis subsp. lactis and Propionibacterium freudenreichii subsp. shermanii.[11]

Herbs[edit | edit source]

Herbs shown to inhibit S. aureus include Bacopa monnieri,[12] green tea extracts,[13] turmeric,[14] milk thistle,[15] nigella,[16], cinnamon,[17] and shrubby sophora.[18][19][20] This may suggest a role for equilibrant and protandim in the control of S. aureus.

Mastic gum also has anti-S. aureus activity.[21]
