Escherichia coli O121

Escherichia coli O121 is a serotype of Escherichia coli, a species of bacteria that lives in the lower intestines of mammals.^[1] The presence of many serotypes of E. coli in animals is beneficial or does not cause disease. However, E. coli O121 has been recognized as a potential disease causing serotype of bacteria. Unlike Escherichia coli O157:H7, another pathogenic serotype of E. coli, little is known about the public health significance of O121.
