Book Description
Recent research in microbial ecology has revealed new tools and new concepts which can stimulate medical microbiology. Similarly, some of the best research in microbial ecology has been carried out by medical microbiologists trying to understand how microorganisms survive and live in a particular ecological niche in the human body. This new volume emphasizes how interaction between these two disciplines can stimulate new research approaches and lead to unifying concepts. Experts review important new topics in microbiology, including quorum sensing, horizontal gene transfer in Vibrio cholerae, anthrax toxin, invasion mechanisms, bacterial bleaching of corals, response to starvation, cell–to–cell interactions, natural genetic engineering, and prions. Each chapter offers a general introduction to the topic, a specific introduction to the research, a critical evaluation of the most recent research on the subject, and a special section on unresolved questions and future research. The book also provides an up–to–date and comprehensive bibliography. Microbial Ecology and Infectious Disease contains a selection of some of the best recent research in microbial ecology and the mechanisms of infectious disease. It is valuable reading for teachers, students, and researchers in general microbiology, medical microbiology, and microbial ecology.

Book Description
Providing a comprehensive insight into cellular signaling processes in bacteria with a special focus on biotechnological implications, this is the first book to cover intercellular as well as intracellular signaling and its relevance for biofilm formation, host pathogen interactions, symbiotic relationships, and photo- and chemotaxis. In addition, it deals in detail with principal bacterial signaling mechanisms -- making this a valuable resource for all advanced students in microbiology. Dr. Krämer is a world-renowned expert in intracellular signaling and its implications for biotechnology processes, while Dr. Jung is an expert on intercellular signaling and its relevance for biomedicine and agriculture.

Book Description
Presents a coherent account of many productive lines of investigation, organized as a series of mini-reviews that focus on major research areas including studies on the structure and mechanisms of action of bacterial, viral, and eukaryotic RNA polymerases, and the transcription factors that control their activities. Each review provides a brief but up-to-date account of the progress of research in a particular area, a discussion of the major issues and questions driving that research, and a brief description of the evolving approaches and technologies used to address those questions.

Book Description
This book concerns the intimate association between bacteria and host cells. Many bacterial pathogens are able to invade and survive within cells at mucosal membranes. Remarkably, the bacteria themselves orchestrate this process through the exploitation of host cellular signal transduction pathways. Intracellular invasion can lead to disruption of host tissue integrity and perturbation of the immune system. An understanding of the molecular basis of bacterial invasion and of host cell adaptation to intracellular bacteria will provide fundamental insights into the pathophysiology of bacteria and the cell biology of the host. The book details specific examples of bacteria that are masters of manipulation of eukaryotic cell signaling and relates these events to the broader context of host-pathogen interaction. Written by experts in the field, this book will be of interest to researchers and graduate students in microbiology, immunology, biochemistry, as well as molecular medicine and dentistry.

Book Description
Bacteria in various habitats are subject to continuously changing environmental conditions, such as nutrient deprivation, heat and cold stress, UV radiation, oxidative stress, dessication, acid stress, nitrosative stress, cell envelope stress, heavy metal exposure, osmotic stress, and others. In order to survive, they have to respond to these conditions by adapting their physiology through sometimes drastic changes in gene expression. In addition they may adapt by changing their morphology, forming biofilms, fruiting bodies or spores, filaments, Viable But Not Culturable (VBNC) cells or moving away from stress compounds via chemotaxis. Changes in gene expression constitute the main component of the bacterial response to stress and environmental changes, and involve a myriad of different mechanisms, including (alternative) sigma factors, bi- or tri-component regulatory systems, small non-coding RNA’s, chaperones, CHRIS-Cas systems, DNA repair, toxin-antitoxin systems, the stringent response, efflux pumps, alarmones, and modulation of the cell envelope or membranes, to name a few. Many regulatory elements are conserved in different bacteria; however there are endless variations on the theme and novel elements of gene regulation in bacteria inhabiting particular environments are constantly being discovered. Especially in (pathogenic) bacteria colonizing the human body a plethora of bacterial responses to innate stresses such as pH, reactive nitrogen and oxygen species and antibiotic stress are being described. An attempt is made to not only cover model systems but give a broad overview of the stress-responsive regulatory systems in a variety of bacteria, including medically important bacteria, where elucidation of certain aspects of these systems could lead to treatment strategies of the pathogens. Many of the regulatory systems being uncovered are specific, but there is also considerable “cross-talk” between different circuits. Stress and Environmental Regulation of Gene Expression and Adaptation in Bacteria is a comprehensive two-volume work bringing together both review and original research articles on key topics in stress and environmental control of gene expression in bacteria. Volume One contains key overview chapters, as well as content on one/two/three component regulatory systems and stress responses, sigma factors and stress responses, small non-coding RNAs and stress responses, toxin-antitoxin systems and stress responses, stringent response to stress, responses to UV irradiation, SOS and double stranded systems repair systems and stress, adaptation to both oxidative and osmotic stress, and desiccation tolerance and drought stress. Volume Two covers heat shock responses, chaperonins and stress, cold shock responses, adaptation to acid stress, nitrosative stress, and envelope stress, as well as iron homeostasis, metal resistance, quorum sensing, chemotaxis and biofilm formation, and viable but not culturable (VBNC) cells. Covering the full breadth of current stress and environmental control of gene expression studies and expanding it towards future advances in the field, these two volumes are a one-stop reference for (non) medical molecular geneticists interested in gene regulation under stress.

Book Description
Focusing on issues of gene organization, regulation, and evolution in the context of the whole life of the cell, this new volume complements the editors' classic 1993 volume Bacillus subtilis and Other Gram-Positive Bacteria. Building upon the previous edition, Bacillus subtilis and Its Closest Relatives contains an updated annotation of the complete B. subtilis genome and includes a unique compilation of major pathways of metabolism and macromolecular synthesis, correlating genes and proteins and assigning new functions to many genes. It also provides clear explanations of the major regulatory mechanisms that are unique to gram-positive bacteria as well as an overview of their special properties. This essential reference offers detailed, current information and is valuable reading for microbiologists, biotechnologists, and students.
