Newly Discovered Reactions From An Old Drug May Lead To New Antibiotics

A mineral found at health food stores could be the key to developing a new line of antibiotics for bacteria that commonly cause diarrhea, tooth decay and, in some severe cases, death.

The trace mineral selenium is found in a number of proteins in both bacterial cells and human cells called selenoproteins. University of Central Florida Associate Professor William Self's research shows that interrupting the way selenoproteins are made can halt the growth of the super bug Clostridium difficile and Treponema denticola, a major contributor to gum disease.
