This book was released on 2019-10-09 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mammalian gastrointestinal tract harbors one of the densest microbial ecosystems found in nature. This microbial community, which is composed of all domains of life, exists in a mutually beneficial relationship with the host. Commensal bacterial communities residing within the intestinal lumen of mammals have evolved to flourish in this microenvironment. To preserve this niche, commensal bacteria act with the host to prevent colonization by invasive pathogens that induce inflammation and disrupt the intestinal niche commensal bacteria rely upon. Thus, it is mutually beneficial to the host and commensal bacteria to inhibit a pathogen's ability to establish an infection. Commensal bacteria express factors that support colonization, maximize nutrient uptake, and produce metabolites that confer a survival advantage over pathogens. Moreover, commensal bacteria stimulate the host's immune defenses and drive tonic expression of anti-microbial factors. In combination, these mechanisms preserve the niche for commensal bacteria and assist the host in preventing infection. An attempt has been made in this Booklet to describe the Role of Commensal Bacteria in defense against Infectious Diseases, comprehensively for the enthusiastic Medicos. …….Dr. H. K. Saboowala.

Download or read book Bugs as Drugs written by Robert A. Britton and published by John Wiley & Sons. This book was released on 2020-07-02 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examining the enormous potential of microbiome manipulation to improve health Associations between the composition of the intestinal microbiome and many human diseases, including inflammatory bowel disease, cardiovascular disease, metabolic disorders, and cancer, have been elegantly described in the past decade. Now, whole-genome sequencing, bioinformatics, and precision gene-editing techniques are being combined with centuries-old therapies, such as fecal microbiota transplantation, to translate current research into new diagnostics and therapeutics to treat complex diseases. Bugs as Drugs provides a much-needed overview of microbes in therapies and will serve as an excellent resource for scientists and clinicians as they carry out research and clinical studies on investigating the roles the microbiota plays in health and disease. In Bugs as Drugs, editors Robert A. Britton and Patrice D. Cani have assembled a fascinating collection of reviews that chart the history, current efforts, and future prospects of using microorganisms to fight disease and improve health. Sections cover traditional uses of probiotics, next-generation microbial therapeutics, controlling infectious diseases, and indirect strategies for manipulating the host microbiome. Topics presented include: How well-established probiotics support and improve host health by improving the composition of the intestinal microbiota of the host and by modulating the host immune response. The use of gene editing and recombinant DNA techniques to create tailored probiotics and to characterize next-generation beneficial microbes. For example, engineering that improves the anti-inflammatory profile of probiotics can reduce the number of colonic polyps formed, and lactobacilli can be transformed into targeted delivery systems carrying therapeutic proteins or bioengineered bacteriophage. The association of specific microbiota composition with colorectal cancer, liver diseases, osteoporosis, and inflammatory bowel disease. The gut microbiota has been proposed to serve as an organ involved in regulation of inflammation, immune function, and energy homeostasis. Fecal microbiota transplantation as a promising treatment for numerous diseases beyond C. difficile infection. Practical considerations for using fecal microbiota transplantation are provided, while it is acknowledged that more high-quality evidence is needed to ascertain the importance of strain specificity in positive treatment outcomes. Because systems biology approaches and synthetic engineering of microbes are now high-throughput and cost-effective, a much wider range of therapeutic possibilities can be explored and vetted.

Download or read book Bacterial Biofilms written by Tony Romeo and published by Springer Science & Business Media. This book was released on 2008-02-26 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the biological world, bacteria thrive predominantly in surface-attached, matrix-enclosed, multicellular communities or biofilms, as opposed to isolated planktonic cells. This choice of lifestyle is not trivial, as it involves major shifts in the use of genetic information and cellular energy, and has profound consequences for bacterial physiology and survival. Growth within a biofilm can thwart immune function and antibiotic therapy and thereby complicate the treatment of infectious diseases, especially chronic and foreign device-associated infections. Modern studies of many important biofilms have advanced well beyond the descriptive stage, and have begun to provide molecular details of the structural, biochemical, and genetic processes that drive biofilm formation and its dispersion. There is much diversity in the details of biofilm development among various species, but there are also commonalities. In most species, environmental and nutritional conditions greatly influence biofilm development. Similar kinds of adhesive molecules often promote biofilm formation in diverse species. Signaling and regulatory processes that drive biofilm development are often conserved, especially among related bacteria. Knowledge of such processes holds great promise for efforts to control biofilm growth and combat biofilm-associated infections. This volume focuses on the biology of biofilms that affect human disease, although it is by no means comprehensive. It opens with chapters that provide the reader with current perspectives on biofilm development, physiology, environmental, and regulatory effects, the role of quorum sensing, and resistance/phenotypic persistence to antimicrobial agents during biofilm growth.

Download or read book Understanding and Exploiting Host Commensal Interactions to Combat Pathogens written by Sudhanshu Shekhar and published by Frontiers Media SA. This book was released on 2020-01-14 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trillions of commensal microbes reside on and inside the human body, including the intestinal and respiratory tracts, which encompass various microbial taxa, such as bacteria, fungi, archea and viruses. The close proximity of microbes with the host provides an opportunity to continually interact with each other. Advances in research approaches, including high-throughput sequencing, have allowed us to study host and commensal microbes at the genetic and functional levels. Recent studies suggest that commensal microbes play a crucial role in the development of the host’s immune system and induce innate and adaptive immune responses against pathogens. It is also becoming apparent that the gut commensals are endowed with a capacity to alter immune responses in organs beyond the intestine, such as the lungs, highlighting the significance of the gut commensals in controlling systemic immunity. On the other hand, the host’s immune system possesses the ability to shape the repertoire of commensal microbes and contribute to the establishment of beneficial relationships with them. A better understanding of host-commensal interactions will be important for designing effective vaccines and therapeutics against pathogens. This Research Topic sheds light on our current understanding of the interplay between the host’s immune system and commensal microbes and how this interplay can be exploited for prophylactic and/or therapeutic strategies against pathogens.

Available in PDF, EPUB and Kindle. Book excerpt: A practical plan for strengthening the incredible antiviral defenses located in your gut and resolving symptoms—from a renowned gastroenterologist and the author of Gutbliss. Multiple studies have now confirmed a dramatic link between the health of our microbiome—the trillions of bacteria that live in our digestive tract—and our likelihood of getting devastating viral illnesses like COVID-19. Low-fiber diets, limited exposure to nature, and overzealous use of pharmaceuticals have messed up our microbiome, making many of us more susceptible to viruses than we naturally should be. But the good news is that unlike our genes, our microbiome is constantly evolving, offering a pathway back to health for those who are suffering, and proven protection for those who want to stay well. In The Anti-Viral Gut, Dr. Robynne Chutkan explains this groundbreaking research and offers a prescriptive plan for anyone trying to avoid or recover from a viral illness to rehab their gut microbes and restore their health. In this powerful road map to strengthening the gut-immune system, Chutkan gives practical advice for balancing both your internal and external environment by optimizing diet, exercise, sleep, and time outdoors to boost your host defenses and overall health. The Anti-Viral Gut includes: a step-by-step nutrition plan, including recipes to improve your good gut bacteria and an explanation of which foods and preparation methods bring you the fastest results protocols for replacing immune-suppressive, microbiome-disruptive medications with safer alternatives guidelines for exercise, sleep hygiene, and stress reduction methods for working mindfulness, breathwork, and meditation into your daily routine advice on maximizing the potent antiviral effects of nature Complete with inspiring stories from Dr. Chutkan’s own patients who have battled COVID-19, The Anti-Viral Gut will empower readers to jump-start their journey toward healing.
Download or read book Microbial Ecology in States of Health and Disease written by Institute of Medicine and published by National Academies Press. This book was released on 2014-02-18 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Individually and collectively, resident microbes play important roles in host health and survival. Shaping and shaped by their host environments, these microorganisms form intricate communities that are in a state of dynamic equilibrium. This ecologic and dynamic view of host-microbe interactions is rapidly redefining our view of health and disease. It is now accepted that the vast majority of microbes are, for the most part, not intrinsically harmful, but rather become established as persistent, co-adapted colonists in equilibrium with their environment, providing useful goods and services to their hosts while deriving benefits from these host associations. Disruption of such alliances may have consequences for host health, and investigations in a wide variety of organisms have begun to illuminate the complex and dynamic network of interaction - across the spectrum of hosts, microbes, and environmental niches - that influence the formation, function, and stability of host-associated microbial communities. Microbial Ecology in States of Health and Disease is the summary of a workshop convened by the Institute of Medicine's Forum on Microbial Threats in March 2013 to explore the scientific and therapeutic implications of microbial ecology in states of health and disease. Participants explored host-microbe interactions in humans, animals, and plants; emerging insights into how microbes may influence the development and maintenance of states of health and disease; the effects of environmental change(s) on the formation, function, and stability of microbial communities; and research challenges and opportunities for this emerging field of inquiry.

Download or read book Bacterial Resistance to Antibiotics written by Boyan B. Bonev and published by John Wiley & Sons. This book was released on 2019-06-10 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: AN AUTHORITATIVE SURVEY OF CURRENT RESEARCH INTO CLINICALLY USEFUL CONVENTIONAL AND NONCONVENTIONAL ANTIBIOTIC THERAPEUTICS Pharmaceutically-active antibiotics revolutionized the treatment of infectious diseases, leading to decreased mortality and increased life expectancy. However, recent years have seen an alarming rise in the number and frequency of antibiotic-resistant "Superbugs." The Centers for Disease Control and Prevention (CDC) estimates that over two million antibiotic-resistant infections occur in the United States annually, resulting in approximately 23,000 deaths. Despite the danger to public health, a minimal number of new antibiotic drugs are currently in development or in clinical trials by major pharmaceutical companies. To prevent reverting back to the pre-antibiotic era—when diseases caused by parasites or infections were virtually untreatable and frequently resulted in death—new and innovative approaches are needed to combat the increasing resistance of pathogenic bacteria to antibiotics. Bacterial Resistance to Antibiotics – From Molecules to Man examines the current state and future direction of research into developing clinically-useful next-generation novel antibiotics. An internationally-recognized team of experts cover topics including glycopeptide antibiotic resistance, anti-tuberculosis agents, anti-virulence therapies, tetracyclines, the molecular and structural determinants of resistance, and more. Presents a multidisciplinary approach for the optimization of novel antibiotics for maximum potency, minimal toxicity, and appropriated degradability Highlights critical aspects that may relieve the problematic medical situation of antibiotic resistance Includes an overview of the genetic and molecular mechanisms of antibiotic resistance Addresses contemporary issues of global public health and longevity Includes full references, author remarks, and color illustrations, graphs, and charts Bacterial Resistance to Antibiotics – From Molecules to Man is a valuable source of up-to-date information for medical practitioners, researchers, academics, and professionals in public health, pharmaceuticals, microbiology, and related fields.

Download or read book Public Health Significance of Urban Pests written by Xavier Bonnefoy and published by World Health Organization. This book was released on 2008 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]
