Skin Probiotics Offer Best Defense Against MRSA Infections

Researchers from the University of California at San Diego have determined that healthy skin bacteria serve as defense mechanisms against infection, and can fight off even the sometimes deadly MRSA infection.

This of course explains why not everyone who comes into contact with the methicillin-resistant Staphylococcus aureus (MRSA) bacteria – or any other skin infective agent for that matter – becomes infected.

The researchers tested a typical skin (probiotic) bacteria Propionibacterium acnes against MRSA in several settings. The researchers conducted laboratory studies by growing cultures of Propionibacterium acnes with and without their preferred food medium of glycerol, and tested these varying cultures against a species of MRSA bacteria known to be one of the most fatal – the USA300 species.
