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
Many bacterial diseases are caused by organisms growing together as communities or biofilms. These microorganisms have the capacity to coordinately regulate specific sets of genes by sensing and communicating amongst themselves utilizing a variety of signals. This book examines the mechanisms of quorum sensing and cell-to-cell communication in bacteria and the roles that these processes play in regulating virulence, bacterial interactions with host tissues, and microbial development. Recent studies suggest that microbial cell-to-cell communication plays an important role in the pathogenesis of a variety of disease processes.

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

Book Description
This book illustrates the importance and significance of Quorum sensing (QS), it’s critical roles in regulating diverse cellular functions in microbes, including bioluminescence, virulence, pathogenesis, gene expression, biofilm formation and antibiotic resistance. Microbes can coordinate population behavior with small molecules called autoinducers (AHL) which serves as a signal of cellular population density, triggering new patterns of gene expression for mounting virulence and pathogenesis. Therefore, these microbes have the competence to coordinate and regulate explicit sets of genes by sensing and communicating amongst themselves utilizing variety of signals. This book descry emphasizes on how bacteria can coordinate an activity and synchronize their response to external signals and regulate gene expression. The chapters of the book provide the recent advancements on various functional aspects of QS systems in different gram positive and gram negative organisms. Finally, the book also elucidates a comprehensive yet a representative description of a large number of challenges associated with quorum sensing signal molecules viz. virulence, pathogenesis, antibiotic synthesis, biosurfactants production, persister cells, cell signaling and biofilms, intra and inter-species communications, host-pathogen interactions, social interactions & swarming migration in biofilms.

Book Description
A multiplicity of biotrophic micro-organisms interact with plants in nature, forming symbiotic relationships that range from mutualism to antagonism. Microorganisms that have adopted biotrophy as a lifestyle are able to colonize the plant and often to cross the plant cell boundaries by forming intracellular structures that are the site of nutrient uptake/exchange. To establish themselves within plant tissues, both mutualistic and pathogenic biotrophs need to overcome the plant defense response through an exchange of molecular signals. Our knowledge of the nature of these signals and their function in the interaction has rapidly increased over the last few years. This volume focuses on the genetic, molecular and cellular components involved in the communication between partners of well-known symbioses, but also reports on the advances for less studied systems.

Book Description
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.

Book Description
Quorum sensing (QS) is a process of bacterial cooperative behaviour that has an effect on gene regulation. This cell-to-cell communication system involves the production of signalling molecules according to cell density and growth stage. Virulence, the ability to infest a habitat and cause disease, is also governed by such communication signals. Quorum Sensing: Molecular mechanism and biotechnological application collects, describes and summarizes the most interesting results obtained from experts working on QS mechanisms. It contributes to the understanding of the molecular basis that regulates this mechanism, and describes new findings in fields of application. This volume describes the QS mechanism from its molecular basis to medical applications such as antibiotic therapy and involvement of QS in pathologies. This reference also analyzes its potential use in biotechnological applications such as food packaging, drug delivery, and marine biofilm. The broad scope of this title will be of significant use to researchers across several fields with interest in QS, including to microbiologists, chemists, biochemists and ecologists. - Describes Quorum Sensing (QS) mechanisms from their molecular basis, to their clinical applications - Spans several fields in relation to QS, including microbiology, chemistry, biochemistry and ecology - Considers QS as an approach to the discovery of new antibiotics - Looks at QS as a means to understand the microbial world and towards use of bacteria and their products in biotechnological applications - Summarizes key results on QS mechanisms' molecular basis and fields of application
