Understanding Why C. Difficile Causes Disease -- It's Hungry

...n is studying a five-gene region of the bacteriums chromosome known as the tcd locus. Two of the genes code for the toxins the bacterium produces that cause disease and a third gene codes for a protein that makes a hole in the organisms cell envelope to let the toxins out. The last two genes are of greatest int...
