The bacteria found in the human intestine is Escherichia coli. E. coli is a common bacterium that resides in the lower intestine of humans and other warm-blooded animals. It plays an essential role in the gut by aiding in digestion, synthesizing vitamins like vitamin K, and maintaining a healthy balance of gut flora. Most strains of E. coli are harmless and beneficial, contributing to the proper functioning of the digestive system. However, some pathogenic strains can cause foodborne illnesses and infections. Despite these exceptions, E. coli is a key part of the natural gut microbiota. It helps protect the intestine from colonization by harmful pathogens and supports the immune system. Research on E. coli has also contributed significantly to the fields of genetics and microbiology.
