This book was released on 2001-12-12 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pathogenic bacteria have unique biological properties, which enable them to invade a host and cause sickness. The molecular bases of these biological properties are the determinants of pathogenicity, and the research objectives are to recognize them, identify them chemically and relate their structure to function. Most of our present knowledge comes from studies with cultures in vitro. However, there is a rising interest in bacterial behaviour in the infected host and new methods have been developed for studying it. This book describes those methods and shows how they, and a recent surge in conventional studies, are shedding light on the activities of bacterial pathogens in vivo. It discusses bacterial and host factors that operate in vivo to cause illness, showing how phenomena recognized in vitro relate to behaviour in vivo and, if evidence of relevance is not available now, indicating how it might be obtained./a

Download or read book Metabolism and Bacterial Pathogenesis written by Tyrrell Conway and published by ASM Press. This book was released on 2015-09-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundbreaking thinking on how bacterial metabolism is foundational to pathogenesis For too long, bacterial metabolism and bacterial pathogenesis have been studied as separate entities. However, the scientific community is beginning to realize that not only are bacterial nutrient acquisition and utilization essential for pathogenesis, but that interfering with the pathogen-specific metabolic pathways used during infection can regulate virulence factor expression and might lead to effective breakthroughs in a variety of treatments. Editors Paul Cohen and Tyrrell Conway, who pioneered the use of metabolic mutants in competitive colonization assays, an approach now widely used to investigate the nutrition of pathogens in vivo, are uniquely qualified to advance our knowledge of this integrative field of research. They convened a group of contributors who are breaking new ground in understanding how bacterial metabolism is foundational to pathogenesis to share their expert perspectives and outlook for the future. Beginning with overviews, Metabolism and Bacterial Pathogenesis covers a wide range of diseases and both Gram-positive and -negative bacteria that serve as model systems for in vitro and in vivo investigations intracellular, respiratory, and enteric pathogens pathogen-specific nutrient acquisition in hosts mechanisms of host-driven metabolic adaptation by pathogens metabolic regulation of virulence gene expression Useful for specialists in bacterial pathogenesis and specialists in metabolism as well as molecular biologists, physicians, veterinarians, dentists, graduate and undergraduate students, and laboratory technicians, Metabolism and Bacterial Pathogenesis is also essential reading for scientists studying the microbiome.

Download or read book Microbial Threats to Health written by Institute of Medicine and published by National Academies Press. This book was released on 2003-08-25 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infectious diseases are a global hazard that puts every nation and every person at risk. The recent SARS outbreak is a prime example. Knowing neither geographic nor political borders, often arriving silently and lethally, microbial pathogens constitute a grave threat to the health of humans. Indeed, a majority of countries recently identified the spread of infectious disease as the greatest global problem they confront. Throughout history, humans have struggled to control both the causes and consequences of infectious diseases and we will continue to do so into the foreseeable future. Following up on a high-profile 1992 report from the Institute of Medicine, Microbial Threats to Health examines the current state of knowledge and policy pertaining to emerging and re-emerging infectious diseases from around the globe. It examines the spectrum of microbial threats, factors in disease emergence, and the ultimate capacity of the United States to meet the challenges posed by microbial threats to human health. From the impact of war or technology on disease emergence to the development of enhanced disease surveillance and vaccine strategies, Microbial Threats to Health contains valuable information for researchers, students, health care providers, policymakers, public health officials. and the interested public.
Download or read book Treating Infectious Diseases in a Microbial World written by National Research Council and published by National Academies Press. This book was released on 2006-01-03 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans coexist with millions of harmless microorganisms, but emerging diseases, resistance to antibiotics, and the threat of bioterrorism are forcing scientists to look for new ways to confront the microbes that do pose a danger. This report identifies innovative approaches to the development of antimicrobial drugs and vaccines based on a greater understanding of how the human immune system interacts with both good and bad microbes. The report concludes that the development of a single superdrug to fight all infectious agents is unrealistic.

Download or read book The Social Biology of Microbial Communities written by Institute of Medicine and published by National Academies Press. This book was released on 2013-01-10 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with the germ theory of disease in the 19th century and extending through most of the 20th century, microbes were believed to live their lives as solitary, unicellular, disease-causing organisms . This perception stemmed from the focus of most investigators on organisms that could be grown in the laboratory as cellular monocultures, often dispersed in liquid, and under ambient conditions of temperature, lighting, and humidity. Most such inquiries were designed to identify microbial pathogens by satisfying Koch's postulates.3 This pathogen-centric approach to the study of microorganisms produced a metaphorical "war" against these microbial invaders waged with antibiotic therapies, while simultaneously obscuring the dynamic relationships that exist among and between host organisms and their associated microorganisms-only a tiny fraction of which act as pathogens. Despite their obvious importance, very little is actually known about the processes and factors that influence the assembly, function, and stability of microbial communities. Gaining this knowledge will require a seismic shift away from the study of individual microbes in isolation to inquiries into the nature of diverse and often complex microbial communities, the forces that shape them, and their relationships with other communities and organisms, including their multicellular hosts. On March 6 and 7, 2012, the Institute of Medicine's (IOM's) Forum on Microbial Threats hosted a public workshop to explore the emerging science of the "social biology" of microbial communities. Workshop presentations and discussions embraced a wide spectrum of topics, experimental systems, and theoretical perspectives representative of the current, multifaceted exploration of the microbial frontier. Participants discussed ecological, evolutionary, and genetic factors contributing to the assembly, function, and stability of microbial communities; how microbial communities adapt and respond to environmental stimuli; theoretical and experimental approaches to advance this nascent field; and potential applications of knowledge gained from the study of microbial communities for the improvement of human, animal, plant, and ecosystem health and toward a deeper understanding of microbial diversity and evolution. The Social Biology of Microbial Communities: Workshop Summary further explains the happenings of the workshop.
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 Probiotics and Prebiotics in Human Nutrition and Health written by Venketeshwer Rao and published by BoD – Books on Demand. This book was released on 2016-07-13 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Probiotic microorganisms are recognised as being beneficial for human health. Prebiotics are substrates that are used preferentially by the probiotic bacteria for their growth. A great deal of interest has been generated in recent years in identifying probiotic bacteria and prebiotics, their characterization, mechanisms of action and their role in the prevention and management of human health disorders. Together they are referred to as synbiotic. This book is in response to the need for more current and global scope of probiotics and prebiotics. It contains chapters written by internationally recognized authors. The book has been planned to meet the needs of the researchers, health professionals, government regulatory agencies and industries. This book will serve as a standard reference book in this important and fast-growing area of probiotics and prebiotics in human nutrition and health.
Download or read book Lactoferrin written by T. William Hutchens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lactoferrin is an intriguing protein with an interesting structure and several known or suggested biological activities. We feel that attention on this protein has been too limited and diffuse, partly because it has been "hidden" among other well-known iron-binding proteins such as hemoglobin, ferritin and transferrin, but also perhaps because its biological functions are so diverse. Investigators that focus on lactoferrin represent a wide variety of medical and scientific disciplines that do not usually come together. It was our intention to improve that situation with this symposium. In this book, experts from a variety of disciplines describe the present knowledge of the structural features of lactoferrin, its carbohydrate side chains and its capacity to bind different metal ions and anions. Several of the possible physiological functions of lactoferrin are described in detail, including the role of lactoferrin in bacterial killing, its involvement in growth and proliferation, in immune function and in iron absorption. Aspects of the molecular biology of lactoferrin and its specific interactions with different cell types are also included. Finally, as lactoferrin now has become commercially available in larger quantities, possible industrial applications are discussed. The book should give the interested reader a thorough insight into our present knowledge of lactoferrin.
Download or read book Ending the War Metaphor written by Institute of Medicine and published by National Academies Press. This book was released on 2006-07-09 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infectious diseases have existed longer than us, as long as us, or are relatively newer than us. It may be the case that a disease has existed for many, many years but has only recently begun affecting humans. At the turn of the century the number of deaths caused by infections in the United States had been falling steadily but since the '80s has seen an increase. In the past 30 years alone 37 new pathogens have been identified as human disease threats and 12% of known human pathogens have been classified as either emerging or remerging. Whatever the story, there is currently a "war" on infectious diseases. This war is simply the systematic search for the microbial "cause" of each disease, followed by the development of antimicrobial therapies. The "war" on infectious diseases, however, must be revisited in order to develop a more realistic and detailed picture of the dynamic interactions among and between host organisms and their diverse populations of microbes. Only a fraction of these microbes are pathogens. Thus, in order to explore the crafting of a new metaphor for host-microbe relationships, and to consider how such a new perspective might inform and prioritize biomedical research, the Forum on Microbial Threats of the Institute of Medicine (IOM) convened the workshop, Ending the War Metaphor: The Changing Agenda for Unraveling the Host-Microbe Relationship on March 16-17, 2005. Workshop participants examined knowledge and approaches to learning about the bacterial inhabitants of the human gut, the best known host-microbe system, as well as findings from studies of microbial communities associated with other mammals, fish, plants, soil, and insects. The perspective adopted by this workshop is one that recognizes the breadth and diversity of host-microbe relationships beyond those relative few that result in overt disease. Included in this summary are the reports and papers of individuals participating in the Forum as well as the views of the editors.
Download or read book Bacteriophages and Biofilms written by Stephen T. Abedon and published by Nova Biomedical Books. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteriophages (phages) are the viruses of bacteria and biofilms that represent a frequent niche for bacteria, where they are embedded in extensive extracellular polymeric substances (EPS) and can be structured into complex microcolonies. As a consequence of the resulting spatial structure and heterogeneity, phage-bacterial interactions within biofilms can be more complicated than those between phages and planktonic bacteria. This book presents and discusses research which provides a better understanding of the biology of phages interacting with biofilms.
