For E. coli in molecular biology, see Escherichia coli (molecular biology) . Escherichia coli (/ËÉÊÉ¨ËrÉªkiÉ ËkoÊlaÉª/ ; also known as 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).he genome sequence of the type strain of E. coli has been added to this collection not before 2014. Comparison of these sequences shows a remarkable amount of diversity; only about 20% of each genome represents sequences present in every one of the isolates, while around 80% of each genome can vary among isolates.
