Escherichia coli is a rod-shaped bacterium. Each bacterium measures approximately 0.5 Î¼m in width by 2 Î¼m in length. E. coli is a Gram-negative bacterium. E. coli cells stain Gram negative because they have a thin cell wall with only 1 to 2 layers of peptidoglycan. E. coli is a facultative anaerobe, which means it does not require oxygen, but grows better in the presence of oxygen.
In addition to E. coli O157, many other  non-O157 STECs  also cause disease. Some  non-O157 STECs  cause disease that is often severe, resulting in bloody diarrhea and sometimes hemolytic uremic syndrome (HUS), which is a type of kidney failure.ost E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract.
