Ecoli

Escherichia coli, commonly abbreviated as E. coli, is a rod-shaped bacterium found in the lower intestine of warm-blooded organisms, including humans. It is a facultative anaerobe, meaning it can survive with or without oxygen. Most strains of E. coli are harmless and play a beneficial role in the digestive system by producing vitamin K and preventing the colonization of harmful bacteria. However, certain strains can cause illness.

Some pathogenic strains of E. coli can lead to foodborne illnesses, characterized by symptoms such as diarrhea, abdominal cramps, and vomiting. Severe infections can result in complications like hemolytic uremic syndrome (HUS), a serious kidney condition. Transmission typically occurs through the consumption of contaminated food or water, or through direct contact with infected individuals or animals. Proper hygiene practices, such as thorough handwashing and cooking food to the correct temperature, are crucial in preventing E. coli infections. E. coli is also a widely used model organism in molecular biology and genetics research due to its rapid growth rate and well-understood genetic makeup. Its presence in the environment is often monitored as an indicator of fecal contamination.
