This fluorescent antibody-stained photomicrograph depicted numbers of Gram-negative, enteropathogenic Escherichia coli (EEC), 0127:B8 strain, bacteria, which were found in a fecal smear.
What is Escherichia coli?
Escherichia coli, abbreviated as E. coli, are a large and diverse group of bacteria. Although most strains of E. coli are harmless, others can make you sick. Some kinds of E. coli can cause diarrhea, while others cause urinary tract infections,  respiratory illness and pneumonia, and other illnesses. Still other  kinds of E. coli are used as markers for water contamination—so you might hear about E. coli being found in drinking water, which are not themselves harmful, but indicate the water is contaminated.
