The normal microbial flora (locust flora, colonization flora, resident germs or commensals) is the entirety of the microorganisms that live on the inner and outer body surfaces of humans and other living beings without normally penetrating the body (infection) and causing a disease.

The term "flora" actually means a collective of plants (flora, the Roman goddess of the flower). Nevertheless, this term has also been used and has been preserved for a community of micro-organisms, a micro-organism biocenosis.

The skin flora (the different body regions) is differently composed than the mucous membrane flora in the oral cavity, the various sections of the digestive tract esophagus / stomach and colon ("gut flora") and in the respiratory tract. The small intestine is largely free of microorganisms.
