E. Coli vs. Klebsiella: What's the Difference?
Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 30, 2023
E. coli and Klebsiella are both gram-negative bacteria, but while E. coli is commonly found in the intestines, Klebsiella can be found in various environments including the human mouth.
Key Differences
E. coli, short for Escherichia coli, is a type of bacteria that is most often associated with the intestines of warm-blooded organisms, including humans. On the other hand, Klebsiella is a genus of bacteria that can be found in multiple environments, including the human mouth, intestines, and skin.

Most E. coli strains are harmless and are actually an important part of the gut flora in humans. They assist in breaking down food and absorbing nutrients. Conversely, Klebsiella species can be part of the normal flora but some strains can cause infections like pneumonia, bloodstream infections, and urinary tract infections.

E. coli has garnered significant attention due to certain strains that can cause foodborne illnesses. Ingesting contaminated food or water can lead to infections. Klebsiella, however, is especially known in healthcare settings, as it can cause hospital-acquired infections and is often resistant to multiple antibiotics.

Both E. coli and Klebsiella have been subjects of medical research due to their implications in human health. While E. coli is studied often for its roles in both beneficial gut health and foodborne outbreaks, Klebsiella is closely watched for its potential in antibiotic resistance and hospital-related infections.
