Stopping MRSA before it becomes dangerous is possible

Published on Monday, 7 December 2009 14:00 from ScienceDaily

Most scientists believe that staph infections are caused by many bacterial cells that signal each other to emit toxins. The signaling process is called quorum sensing because many bacteria must be present to start the process. But scientists have now determined that the very first stage of staph infection, when bacteria switch from a harmless to a virulent form, occurs in a single cell and that this individual process can be stopped by the application of a simple protein.
