Gastrointestinal Toxicology of Monogastrics

  • Chapter
Gastrointestinal Microbiology

Part of the book series: Chapman & Hall Microbiology Series ((CHMBS))

Abstract

The gastrointestinal tract is one of the most active sites in the body where metabolism takes place. A large number of microorganisms are found in the gastrointestinal tract. The number of microorganisms per gram colon contents exceeds 1011/g dry weight, constituting more than 40% of the total fecal mass (Stephen and Cummings 1980). These microorganisms represent a sources of great metabolic power and may play a role in many disease processes including cancer (Goldin 1986a,b, 1990, Gorbach and Goldin 1990, Hill 1987, Mallett and Rowland 1990). The microbiota produce a wide range of substances de novo and/or from ingested sources including the diet. These toxic substances may be mutagens, tumor promoters, initiators or carcinogens in addition to many types of toxins. Toxins are defined as chemicals which have adverse effects on living systems. Toxicology today involves studies of the effects of specific substances on any biological system, whether a whole organism, organ or tissue, through the interaction of toxin with target.
