Escherichia coli, one of the many species of bacteria present in the human gut. Gut flora (gut microbiota, or gastrointestinal microbiota) is the complex community of microorganisms that live in the digestive tracts of humans and other animals, including insects. The gut metagenome is the aggregate of all the genomes of gut microbiota. The gut is one niche that human microbiota inhabit.
Habitat of E. coli. E. coli was discovered by Theodor Escherich in 1885 after isolating it from the faeces of newborns. E. coli is the normal flora of human body. The niche of E. coli depends upon the nutrients availability within the intestine of host organisms. The primary habitat of E. coli is in the gastrointestinal (GI) tract of human and many other warm blooded animals. It is found in the mucus or the epithelium on the wall of intestine. Most commonly found in the colon of large intestine. Most of them are harmless and opportunistic.
