WebOne Escherichia coli (E. coli) strain that causes a severe intestinal infection in humans is known as enterohemorrhagic E. coli (EHEC). It’s the most common strain to cause illness in people. It’s different from other E. coli because it produces a potent toxin called Shiga toxin. This toxin damages the lining of the intestinal wall, causing bloody diarrhea.
