Common Food Additive May promote C. diff

An article appearing in Nature suggested that a common food additive known as trehalose might be responsible for the current Clostridium difficile epidemic. The Nature paper shows us that two of the most virulent strains of C. diff, including the “hypervirulent” ribotype 027, can metabolize even trace amounts of trehalose. They go on to show that when strains are mixed together, low
