Digestive Tract Diseases and Infection: Intestinal Microbiology

Abstract

Human digestive tract is one of the most important and vulnerable organ of the human functions. The digestive tract is formed of several anatomic sites which cooperate during digestive activities: those multiple anatomic sites possess microbiologic characteristics and each is capable to undergo pathologic conditions. In normal conditions, a natural bacterial flora is present in the digestive tract and constitutes a source of maturation of immune systems: Lactobacilli, Bifidobacterium lactis, Enterobacteriaceae, Esherichia coli, Proteus spp, anaerobes, are normal inhabitants of the gut.
