An illustration of Escherichia coli (commonly abbreviated E. coli) is a Gram-negative, facultatively anaerobic, rod-shaped bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most E. coli strains are harmless, but some serotypes can cause serious food poisoning in their hosts, and are occasionally responsible for product recalls due to food contamination. Though this 3D illustration would appear to depict a larger entity, they are only about 2 nanometers in length.
