These bacteria exist in many different parts of the body, and their presence usually does not cause any problems for the host body. The following is a list of the main sites for bacteria that consitute the normal flora. 1  The skin, especially the moist areas, such as the groin and between the toes.2  The respiratory tract, particularly the nose. 3  Urinary tract. 4  The digestive tract, i.e. the mouth, the terminal ileum and the colon.hese bacteria exist in many different parts of the body, and their presence usually does not cause any problems for the host body.
