Early-Stage Discoveries: Probiotic reduces staph infection

Staph aureus is a common bacterium in the body, usually found in the skin, but also populates the nose or gut without harm. But, when the skin barrier breaks, or the immune system weakens, S. aureus can cause skin infection, or even fatal pneumonia and sepsis.

In the lab, doctors fed mice the probiotic bacillus, which completely eliminated all strains of S. aureus. Doctors hope to develop a probiotic that can eliminate methicillin-resistant S. aureus (MRSA), a treatment-resistant strain common in hospitals.
