Cells and microbial flora of the gastrointestinal tract

Abstract

This chapter describes the cells and microbial flora of the gastrointestinal (GI) tract. Around 10 billion human cells, which are replaced every three to four days, interact with an even greater number of microorganisms, a ratio of around one cell to ten microorganisms. This interaction is key to the proper development and functioning of the GI tract and the immune system, as well as to the assimilation and production of essential nutrients. However, scientists are only just beginning to understand the full extent of this vital, symbiotic relationship. The chapter considers these complex interactions, in health and disease, and how an understanding of these mechanisms may lead to improvements in health and the management of some types of illness.
