Gastrointestinal Microbiology

This reference supplies a comprehensive and current overview of every aspect of gastrointestinal microbiota. Expertly written chapters cover conventional and molecular techniques for the study of differing microbial populations, as well as the analysis of microbial activity and interaction with host bodies.

Extremely diverse and complicated bacterial and protozoan populations inhabit the rumen and intestinal tract of animals, and there is a delicate balance among the individual populations within this complex microbial community. This authoritative edited volume, the first in a two-volume set, reviews the gut environment and the fermentations taking place in animal digestive tracts. It is an essential source of reference for microbial ecologists and physiologists, medical microbiologists and gastroenterologists, biochemists, nutritionists, veterinarians and animal scientists, and wildlife ecologists.

The gastrointestinal tract is a complex anaerobic microbial ecosystem containing a vast assemblage of resident microorganisms performing a multitude of metabolic activities that play a key role in health and disease of humans and animals. Furthermore, the gastrointestinal microbes have a dominant impact on the growth and productivity of both ruminant and non-ruminant animals. This two-volume series on Gastrointestinal Microbiology reviews the literature and provides a comprehensive account of the biological significance of the microbiota present in the alimentary tract of a wide range of animals, in terms of their nutritional ecology, biochemical activities, development and composition, interactions and role in host health and disease. Recent developments in the areas of molecular ecology, bacterial genetics, immunological aspects of host microbe interactions at the level of the intestinal mucosa, bacterial translocation and intestinal disease are included. Although emphasis is placed on domestic ruminants and man, systems which have been extensively researched, this series also provides a full and integrated account of the nutritional ecology and microbial ecology in the gut of many diverse mammals, birds, fish, amphibians, reptiles and insects. This broad perspective allows more realistic interpretation, and better evaluation of, as well as greater insight into, the evolution, ecology, and function of the gastrointestinal ecosystem. These volumes contain contributions from a multidisciplinary group of internationally recognized authors, all active researchers in their particular fields.

Enteric infection has played an important role in the majority of the world's populations, including children (particularly those under four years of age), the aged, the malnourished, military populations, and per sons from industrialized regions traveling to developing areas. The magni tude of the problem has been profound in areas of the world with reduced economic development, where there exists a greater reservoir of entero pathogens and a larger susceptible population with nutritional deficits. Morbidity from enteric infection in developing areas exceeds that seen in industrialized countries by severalfold, with the problem being most seri ous in infants who are bottle-fed and other infants and young children soon after being weaned from the breast ("weanling diarrhea"). Of greater significance than the inverse relationship of diarrhea morbidity with levels of industrial development is the relationship of death from intestinal infection and socioeconomic advancement. Mortality rate from diarrhea is 10 to 100 times greater in developing areas. In many parts of the third world, diarrhea, resultant dehydration, and associated malnutri tion are the leading causes of death in infants and young children and account for as great as one-third of pediatric deaths.

Drawing on expert opinions from the fields of nutrition, gut microbiology, mammalian physiology, and immunology, Diet-Microbe Interactions for Human Health investigates the evidence for a unified disease mechanism working through the gut and its resident microbiota, and linking many inflammation-related chronic diet associated diseases. State of the art post-genomic studies can highlight the important role played by our resident intestinal microbiota in determining human health and disease. Many chronic human diseases associated with modern lifestyles and diets — including those localized to the intestinal tract like inflammatory bowel disease and celiac disease, and more pervasive systemic conditions such as obesity, diabetes and cardiovascular disease — are characterized by aberrant profiles of gut bacteria or their metabolites. Many of these diseases have an inflammatory basis, often presenting with a chronic low-grade systemic inflammation, hinting at persistent and inappropriate activation of inflammatory pathways. Through the presentation and analysis of recent nutrition studies, this book discusses the possible mechanisms underpinning the disease processes associated with these pathologies, with high fat diets appearing to predispose to disease, and biologically active plant components, mainly fiber and polyphenols, appearing to reduce the risk of chronic disease development. One comprehensive, translational source for all aspects of nutrition and diet's effect on gastrointestinal health and disease Experts in nutrition, diet, microbiology and immunology take readers from the bench research (cellular and biochemical mechanisms of vitamins and nutrients) to new preventive and therapeutic approaches Clear presentations by leading researchers of the cellular mechanisms underlying diet, immune response, and gastrointestinal disease help practicing nutritionists and clinicians (gastroenterologists, endocrinologists) map out new areas for clinical research and structuring clinical recommendations
