Escherichia coli (pathogenic strains)

Escherichia coli (E. coli) are bacteria commonly found in the intestines of humans and animals, where they usually don't cause harm. However, certain pathogenic strains have acquired genes that enable them to cause illness, primarily through contaminated food or water. These harmful strains can lead to gastrointestinal symptoms like diarrhea, stomach cramps, and vomiting. In some cases, they may cause more severe complications, such as kidney failure. Understanding which strains are dangerous helps in preventing infection through proper food handling, hygiene, and sanitation practices.
