Escherichia coli, commonly known as E. coli, is a diverse group of bacteria that typically live in the intestines of humans and animals. Most strains of E. coli are harmless and play an important role in maintaining a healthy gut microbiome. However, some pathogenic strains can cause serious infections, particularly in the urinary tract, gastrointestinal system, and bloodstream. These pathogenic strains can be acquired through contaminated food or water and may result in symptoms such as diarrhea, abdominal pain, and, in severe cases, kidney failure.
