Book Description
Microbiota-associated pathology can be a direct result of changes in general bacterial composition, such as might be found in periodontitis and bacterial vaginosis, and/or as the result of colonization and/or overgrowth of so called keystone species. The disruption in the composition of the normal human microbiota, or dysbiosis, plays an integral role in human health and human disease. The Human Microbiota and Human Chronic Disease: Dysbioses as a Cause of Human Pathology discusses the role of the microbiota in maintaining human health. The text introduces the reader to the biology of microbial dysbiosis and its potential role in both bacterial disease and in idiopathic chronic disease states. Divided into five sections, the text delineates the concept of the human bacterial microbiota with particular attention being paid to the microbiotae of the gut, oral cavity and skin. A key methodology for exploring the microbiota, metagenomics, is also described. The book then shows the reader the cellular, molecular and genetic complexities of the bacterial microbiota, its myriad connections with the host and how these can maintain tissue homeostasis. Chapters then consider the role of dysbioses in human disease states, dealing with two of the commonest bacterial diseases of humanity – periodontitis and bacterial vaginosis. The composition of some, if not all microbiotas can be controlled by the diet and this is also dealt with in this section. The discussion moves on to the major ‘idiopathic’ diseases afflicting humans, and the potential role that dysbiosis could play in their induction and chronicity. The book then concludes with the therapeutic potential of manipulating the microbiota, introducing the concepts of probiotics, prebiotics and the administration of healthy human faeces (faecal microbiota transplantation), and then hypothesizes as to the future of medical treatment viewed from a microbiota-centric position. Provides an introduction to dysbiosis, or a disruption in the composition of the normal human microbiota Explains how microbiota-associated pathology and other chronic diseases can result from changes in general bacterial composition Explores the relationship humans have with their microbiota, and its significance in human health and disease Covers host genetic variants and their role in the composition of human microbial biofilms, integral to the relationship between human health and human disease Authored and edited by leaders in the field, The Human Microbiota and Human Chronic Disease will be an invaluable resource for clinicians, pathologists, immunologists, cell and molecular biologists, biochemists, and system biologists studying cellular and molecular bases of human diseases.

Book Description
The 21st century has witnessed a complete revolution in the understanding and description of bacteria in eco- systems and microbial assemblages, and how they are regulated by complex interactions among microbes, hosts, and environments. The human organism is no longer considered a monolithic assembly of tissues, but is instead a true ecosystem composed of human cells, bacteria, fungi, algae, and viruses. As such, humans are not unlike other complex ecosystems containing microbial assemblages observed in the marine and earth environments. They all share a basic functional principle: Chemical communication is the universal language that allows such groups to properly function together. These chemical networks regulate interactions like metabolic exchange, antibiosis and symbiosis, and communication. The National Academies of Sciences, Engineering, and Medicine's Chemical Sciences Roundtable organized a series of four seminars in the autumn of 2016 to explore the current advances, opportunities, and challenges toward unveiling this "chemical dark matter" and its role in the regulation and function of different ecosystems. The first three focused on specific ecosystemsâ€"earth, marine, and humanâ€"and the last on all microbiome systems. This publication summarizes the presentations and discussions from the seminars.

Book Description
A great number of diverse microorganisms inhabit the human body and are collectively referred to as the human microbiome. Until recently, the role of the human microbiome in maintaining human health was not fully appreciated. Today, however, research is beginning to elucidate associations between perturbations in the human microbiome and human disease and the factors that might be responsible for the perturbations. Studies have indicated that the human microbiome could be affected by environmental chemicals or could modulate exposure to environmental chemicals. Environmental Chemicals, the Human Microbiome, and Health Risk presents a research strategy to improve our understanding of the interactions between environmental chemicals and the human microbiome and the implications of those interactions for human health risk. This report identifies barriers to such research and opportunities for collaboration, highlights key aspects of the human microbiome and its relation to health, describes potential interactions between environmental chemicals and the human microbiome, reviews the risk-assessment framework and reasons for incorporating chemicalâ€"microbiome interactions.

Book Description
Chronic conditions, such as cardiovascular diseases and diabetes, are now among the greatest threats to human health. As public concerns with complex causality and long development period, chronic diseases generally cannot be cured by medication or prevented by vaccines. Finding new strategies to prevent or treat chronic diseases has long been a challenge to science. Recently, a series of breakthrough studies in intestinal biology, especially in the fields of the gut microbiota, has made us pay close attention to the critical role of intestinal function in chronic disease treatment. Emerging evidence suggests that the gut microbiota could affect the occurrence, diagnosis, and treatment of human conditions, resulting in gut microbiota intervention as a new therapeutic strategy for chronic disorders. However, investigating the intrinsic relation between the gut microbiome and chronic conditions is still in development and requires intense concentration, although the wave of research on the gut microbiome has continued growing and the associated innovations are evolving rapidly. Moreover, translational research on the human microbiome is gaining attention nowadays. Probiotics and their engineered strains, postbiotics, microbial metabolites, prebiotics, microbiota transplantation, and microbiota-targeted interventions are practical approaches to modulating the microbiome. Probiotics, postbiotics, and microbial metabolites are one of the most important and effective interventions. As for disease prevention and treatment, some microbiota-associated live biotherapeutic products (e.g., Akkermansia muciniphila) have been demonstrated with respectable efficacy for human disorders, including diabetes. As for the food nutrition community, supplement with probiotics or prebiotics in diet shows health-promoting benefits for the human being. Collectively, these results inspire us to explore more effective strains to prevent or treat human conditions such as chronic diseases. Undoubtedly, exploring the human-associated microbiota provides a novel perspective for unlocking life’s mystery and unraveling the underlying basic pathogenesis of diseases such as chronic conditions. Targeting microbiota through probiotics, postbiotics, microbial metabolites, prebiotics, microbiota transplantation, and other interventions can generate new therapeutic strategies for chronic disorders in humans. Therefore, this research topic aims to explore the beneficial effects of novel probiotics, postbiotics, and microbial metabolites on chronic diseases, determine the critical role that the human microbiome and probiotics or postbiotics play in chronic conditions changes, determine the basic principles of translational research on probiotics or postbiotics or microbial metabolites and contribute to the prevention and treatment of chronic disorders. We welcome submissions including original research articles, clinical studies, and reviews that contribute innovative knowledge to the following but not limited to potential research topics: •Identification of functional probiotics, postbiotics, and microbial metabolites with human health-promoting, chronic disease prevention and therapeutic properties. •Probiotics/postbiotics or microbial metabolites supplements prevent and treat several most prevalent chronic conditions including cardiovascular diseases, diabetes mellitus, mental disorders, cancers, and pulmonary conditions. •Clinical and experimental studies using multi-omics to reveal the intrinsic relationship between human microbes/microbiota and chronic diseases. •Translational microbiome research on chronic diseases. •The engineered probiotics for the prevention and treatment of chronic diseases, especially related studies involved in exploring the potential molecular mechanisms of engineering microbes. •The key technologies involved in the industrialization process of probiotics, postbiotics, and microbial metabolites.

Book Description
Abstract : A majority of American adults are diagnosed with one or more chronic diseases. Lifestyle choices such as diet, physical activity/ inactivity, and substance abuse play vital roles in the development and maintenance of several pathologies including hypertension and obesity. With clear evidence of correlations between lifestyle choices and hypertension, underlying mechanisms remain unclear. Chronic high consumption of alcohol increases the risk of hypertension and other diseases. Here a potential role of acetate, a bioactive molecule produced as a result of alcohol metabolism, in driving augmented NMDA receptor-mediated sympathetic nerve activity (SNA) is presented. Elevated SNA is characteristic of some chronic diseases such as hypertension, congestive heart failure, and diabetes. Unmasking mechanisms in which neurogenic hypertension develops, along with the potential role of alcohol consumption and metabolism will lead to better target-based therapeutics for the treatment of alcohol related diseases. In addition to alcohol consumption, lifestyle choices such as diet and exercise also play a pivotal role in maintaining health. The data demonstrates the impacts of a high salt diet or moderate aerobic exercise training on the gut microbiome of SD rats. Also, a more optimal sampling unit for microbiome analysis to make associations between healthy and diseased states is proposed. Diet and exercise were independently able to significantly change microbial community composition. These changes were seen in colon mucosa-associated communities however exercise wasn't able to significantly alter microbial community composition in the small intestine or fecal samples. These data suggest a need to not only better understand mucosa-associated microbial communities but also to develop more efficient testing strategies to characterize the gut microbiome and determine its role in health and disease development.

Book Description
The human microbiome refers to the complete microorganisms inhabiting the human body sites including skin, ear, nose, oral cavity, the genital, gastrointestinal and respiratory tracts, and body fluids such as breast milk, saliva, and urine. It is a significant and essential organ recognized for the body and has an established involvement in the host wellbeing, in terms of nutritional requirements and immunomodulation. This book talks about how alteration and imbalance in the same can have clinical implications associated with a multitude of gastrointestinal, lifestyle-associated, and neurodegenerative disorders. How the proliferation of specific groups of bacteria and their metabolic activities, as a result of intestinal dysbiosis leads to the 'leaky gut' condition thereby influences brain activity via the bidirectional gut-brain axis. It also coves the importance of microbial seeding and how it can be influenced by the mode of delivery, nutrition, and medication. This book also provides various therapeutic interventions such as the establishment of stool banks and Faecal microbiota transplantation (FMT) that have recently proved promising in the treatment of ASD, Inflammatory Bowel Disease, and Ulcerative Colitis. This book provides a deeper understanding of the development of the human gut microbiome and the factors driving its dysbiosis. This book is a valuable read for health professionals, medical students, nutritionists, and scientific research communities who are eager to update themselves with recent trends in microbiome research. It will also aid gastroenterologists and nutritionists to make well-informed choices regarding therapeutic regimes.

Book Description
“In Missing Microbes, Martin Blaser sounds [an] alarm. He patiently and thoroughly builds a compelling case that the threat of antibiotic overuse goes far beyond resistant infections.”—Nature Renowned microbiologist Dr. Martin J. Blaser invites us into the wilds of the human microbiome, where for hundreds of thousands of years bacterial and human cells have existed in a peaceful symbiosis that is responsible for the equilibrium and health of our bodies. Now this invisible Eden is under assault from our overreliance on medical advances including antibiotics and caesarian sections, threatening the extinction of our irreplaceable microbes and leading to severe health consequences. Taking us into the lab to recount his groundbreaking studies, Blaser not only provides elegant support for his theory, he guides us to what we can do to avoid even more catastrophic health problems in the future. “Missing Microbes is science writing at its very best—crisply argued and beautifully written, with stunning insights about the human microbiome and workable solutions to an urgent global crisis.”—David M. Oshinsky, author of the Pulitzer Prize-winning Polio: An American Story
