Pathogenic Escherichia coli

Low-temperature electron micrograph of a cluster of E. coli bacteria, magnified 10,000 times. Each individual bacterium is a rounded cylinder.

Escherichia coli (/ˌɛʃəˈrɪkiə ˈkoʊlɪ/ Anglicized to /ˌɛʃəˈrɪkiə ˈkoʊlaɪ/; commonly abbreviated E. coli) is a gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most E. coli strains are harmless, but some serotypes are pathogenic and can cause serious food poisoning in humans, and are occasionally responsible for product recalls. The harmless strains are part of the normal flora of the gut, and can benefit their hosts by producing vitamin K₂, and by preventing the establishment of pathogenic bacteria within the intestine.
