WebEscherichia coli is a member of the family Enterobacteriaceae, which includes gram-negative, facultatively anaerobic rod-shaped bacteria (possessing both a fermentative and respiratory metabolism) and which do not produce the enzyme oxidase. Escherichia coli cells are typically 1.1–1.5-μm-wide, 2–6-μm-long and occur as single straight rods. In the classical sense, six gram-positive genera are typically pathogenic in humans. Two of these, Streptococcus and Staphylococcus, are cocci (sphere-shaped). The remaining organisms are bacilli (rod-shaped) and can be subdivided based on their ability to form spores.
