Escherichia coli (also known as E. coli) is a Gram-negative, facultative aerobic, rod-shaped, coliform 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.
E. coli refers to a wide range of bacteria that can cause various diseases, including pneumonia, urinary tract infections, and diarrhea.
Most strains of E. coli are harmless to humans.
Some strains of E. coli infection can include nausea, vomiting, and fever.
