Book Description
The Bifidobacteria and Related Organisms: Biology, Taxonomy, Applications brings together authoritative reviews on all aspects of Bifidobacteria and related genera. Their place within the Phylum Actinobacteria is discussed first, and this is followed by descriptions of the genera Bifidobacterium, Alloscardovia, Aeriscardovia, Bombiscardovia, Gardnerella, Metascardovia, Parascardovia and Scardovia and the currently accredited species within those genera. The increased availability of genome sequences and molecular tools for studying bifidobacteria provides important information about their taxonomy, physiology and interactions with their host. Also considerations about common bifidobacterial core maintenance during the mutual coevolution of a host and its intestinal microbes could be relevant for health claims for the ability of symbiotic gut bacteria to provide health benefits to their host, and for evaluating such claims in scientifically valid experiments. Chemotaxonomy is important to our understanding of these genera and so is considered along with physiological and biochemical aspects before proceeding to examine clinical and other practical aspects. The ability to maintain pure cultures and to grow cells in industrial quantities when required for applications requires that the cells' environmental and nutritional needs are well understood. Some species are important clinically and as animal digestive tract synbionts—and even play a part in honey production—so these matters are considered along with milk oligosaccharides' roles in gut flora development in neonates. - Presents information on all bacteria in this group in one place - Provides applications and technological considerations placed alongside more academic matters such as nomenclature and phylogeny - Includes basic information on the beneficial role of bifidobacteria in the human gut, with particular importance for infants - Provides information on genomic and gene modification technologies

Book Description
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

Book Description
Human Gut Microbiota in Health and Disease: From Pathogenesis to Therapy is a comprehensive discussion of all the aspects associated with gut microbiota early colonization, its development and maintenance, and its symbiotic relationship with the host to promote health. Chapters illustrate the complex mechanisms and metabolic signalling pathways related to how the gut microbiota maintain proper regulation of glucose, lipid and energy homeostasis and immune response, while mediating inflammatory processes involved in the etiology of many chronic disease conditions. Details are provided on the primary etiological factors of chronic disease, the effects of gut dysbiosis and its associated disease conditions, while providing an overview of therapeutic strategies involving dietary fiber and prebiotics, fecal microbiota transplantation therapy and probiotics. Throughout the chapters, a comprehensive review of peer-reviewed animal and human studies is provided as evidence related to the history of human exposure, safety, tolerance, toxicity, nomenclature, and clinical efficacy of utilizing prebiotic fructans, s, as well as probiotic intervention, and dietary modification in the prevention and intervention of chronic disease conditions. With common use today of pharmaceutical medicine in treating symptoms, and frequent overuse of antibiotics in chronic disease within mainstream medical practice, understanding the etiological mechanisms of dysbiosis-induced chronic disease, and natural approaches that offer prevention and potential cures for these diseases is of vital importance to overall human health. - Details the complex relationship between human microbiota in the gut, oral cavity, urogenital tract and skin as well as their colonization, development and impact of factors that influence the relationship - Illustrates the mechanisms associated with dysbiosis-associated inflammation and its role in the onset and progression in chronic disease - Provides the primary mechanisms and comprehensive scientific evidence for the use of dietary modification, and pro- and pre-biotics in preventing and intervening in chronic disease

Book Description
The human intestine is home of an almost inconceivable large number of microorganisms. The human gut microbiota can therefore be pictured as an organ placed within a host organism. The human gut microbiome, which in total may contain >100 times the number of genes present in our genome, endows us with functional features that we did not have to evolve ourselves. It is recognized that intestinal microbiota plays an important role in human health and disease. In fact, gut bacteria other than metabolize dietary components, may play complex roles such as modulation of the immune system and in reduction of gut infections. Variations in the presence and/or abundance of certain components of the intestinal microbiota have repeatedly been observed in patients that suffer from atopic diseases, inflammatory bowel disease, Crohn disease, ulcerative colitis, infectious colitis, colon cancer and diabetes. In this context, bifidobacteria represent one of the most common bacterial members of the human gut microbiota. Bifidobacteria are anaerobic, Gram-positive, irregular or branched rod-shaped bacteria that are commonly found in the gastro-intestinal tracts (GIT) of humans, especially during the first stages of life and most animal and insects. Bifidobacterial fluctuations seem directly associated with health effects and for these reasons they are being exploited as health-promoting or probiotic bacteria. However, despite the extensive commercial exploitation of bifidobacteria as probiotic bacteria, little is known about their impact or dependency on other members of the human gut microbiota or on their host. Genome analyses have highlighted the existence of gene repertoires encoding products that are responsible for the adaptation of bifidobacteria to the human intestine and intense research efforts at international level are ongoing to understand the molecular details of these interactions. Specifically, the molecular interactions that are presumed to exist between bifidobacteria and the human host, as well as interactions between different residents of intestinal microbiota are the main topic of bifidobacterial research communities.

Book Description
Probiotic bacteria are found in the intestinal microbiota of the host and favor multiple metabolic reactions. Prebiotics provide food for probiotic bacteria and have an effect on their own performance in favor of host health. Numerous metabolic and immunological mechanisms are involved in its effects. Probiotics have been studied for several decades and their use for human consumption is still unclear. However, new types of molecules with prebiotic functions and components of probiotic bacteria with therapeutic potential are still being studied. The versatility of these molecules makes their incorporation into human food and animal diets feasible. This book is a compendium of recent scientific information on the use of probiotics and prebiotics for the benefit of human and animal health.
