The field of bacterial diagnostics has seen unprecedented advances in recent years. The increased need for accurate detection and identification of bacteria in human, animal, food, and environmental samples has fueled the development of new techniques. The field has seen extensive research aided by the information from bacterial genome sequencing projects. Although traditional methods of bacterial detection and identification remain in use in laboratories around the world, there is now a growing trend toward the use of nucleic ac- based diagnostics and alternative biochemically and immunologically based formats. The ultimate goal of all diagnostic tests is the accurate detection, identification, or typing of microorganisms in samples of interest. Although the resulting information is of obvious use in the areas of patient management, animal health, and quality control, it is also of use in monitoring routes of infection and outlining strategies for infection control. There is, therefore, a need to ensure that the information being provided is of the highest standard and that any new technique is capable of delivering this.

Spirochetes comprise a fascinating group of bacteria. Although diverse in terms of their habitat, ecology and infectivity for vertebrate and non-vertebrate hosts, they are often considered together because of their similar cellular morphologies. This volume brings together an international group of experts to provide essential insights into spirochete biology, with an emphasis on recent advances made possible by the availability of genome sequences. As such, it offers a valuable resource for microbiologists and other scientists with an interest in spirochete biology.

Expert scientists critically review the current and most recent advances in the genomics and molecular biology of mycobacteria. The focus is on the topical and most relevant aspects and the authors aim to give readers an insight into the current understan

The book compiles the latest studies on microorganisms thriving in extreme conditions. Microbes have been found in extremely high and low temperatures, highly acidic to saline conditions, from deserts to the Dead sea, from hot-springs to underwater hydrothermal vents- the diversity is incredible. The various chapters highlight the microbial life and describe the mechanisms of tolerance to these harsh conditions, and show how an understanding of these phenomena can help us exploit the microbes in biotechnology. The theme of the book is highly significant since life in these environments can give vital clues about the origin and evolution of life on earth, as a lot of these conditions simulate the environment present billions of years ago. Additionally, the study of adaptation and survival of organisms in such environments can be important for finding life on other planets. This book shall be useful for students, researchers and course instructors interested in evolution, microbial adaptations and ecology in varied environments.

Beginning with the basics of lactic acid bacteria and stress response, then working into specific fields of research and current developments, "Stress Responses of Lactic Acid Bacteria" will serve as an essential guidebook to researchers in the field, industry professionals, and advanced students in the area.

The exploration of stress responses in lactic acid bacteria began in the early 90s and revealed the differences that exist between LAB and the classical model microorganisms. A considerable amount of work has been performed on the main genera / species of LAB regarding the genes implicated and their actual role and regulation, and the mechanisms of stress resistance have also been elucidated. Recent genome and transcriptome analyses complement the proteome and genetic information available today and shed a new light on the perception of and the responses to stress by lactic acid bacteria.

Magnetotactic bacteria (MTB) synthesize intracellular nano-sized minerals of magnetite and/or greigite magnetosomes for magnetic orientation. They play important roles in global iron cycling and sedimentary magnetism, and have a broad range of potential applications in both biotechnological and biomedical fields. However, because the majority of MTB in nature remain unculturable, our understanding of these specific bacteria remains fairly limited. This thesis describes the development of a novel approach for effectively collecting, purifying and characterizing uncultivated magnetotactic bacteria. The diversity, genomic information and rock magnetic properties of various uncultivated MTB are investigated and characterized using a combination of biological and geophysical methods. The results will lead to a better understanding of the biogeography and biomineralization mechanisms of MTB in nature, and improve our knowledge of the contributions of MTB to biogeochemical cycles of elements and sedimentary magnetism.

This volume is also interesting for those studying the physiology, genetics, molecular biology of Pseudomonas and those using novel-omics approaches to understand bacteria of the genus Pseudomonas.

Detailed information dealing with the ecology of mycobacteria is derived from a variety of different scientific fields such as botany, biochemistry, genetics, immunology, microbiology and epidemiology. This text attempts to evaluate this information from an ecological point of view and to develop a strategy for the prevention of tuberculosis and other mycobacterioses based on the ecological behaviour of mycobacteria, especially the potentially pathogenic species capable of either growth in the environment or provoking disease. Regarding the interests of the developing countries, special attention is paid to the ecology of Mycobacterium leprae and to the supporting effect of accompanying mycobacteria in its pathogenicity. On a more positive side, environmental mycobacteria play an important role in the ecology of moorland dragonflies.

Since its early days in the 1990s, the Quorum Sensing (QS) field has grown from a few dozen laboratories, investigating the pathways, proteins, and chemicals that facilitate signaling in bacteria, to hundreds of groups that have integrated evolutionary biology, computer science, mathematics, engineering, and metagenomics to create an ever-expanding and dynamic field. In Quorum Sensing: Methods and Protocols, expert researchers provide an in-depth set of diverse protocols that span this broad area of study. Broken into three detailed sections, the volume covers the detection, isolation, and characterization of the QS signals made by both Gram- and Gram+ bacteria, determination of the function of QS signals in vivo, and the development of QS disruption strategies.

The future of agriculture strongly depends on our ability to enhance productivity without sacrificing long-term production potential. An ecologically and economically sustainable strategy is the application of microorganisms, such as the diverse bacterial species of plant growth promoting bacteria (PGPB). The use of these bio-resources for the enhancement of crop productivity is gaining worldwide importance.

""Bacteria in Agrobiology: Stress Management"" covers the major aspects on PGPR in amelioration of both abiotic and biotic stresses. PGPR mediated in priming of plant defense reactions, nutrient availability and management in saline and cold environment, hormonal signaling, ACC deaminase and its role in ethylene regulation under harsh conditions are suitably described.

Microbial plant pathogens causing qualitative and quantitative losses in all corps are present not only in the infected plants, but also in the environmental comprising of soil, water and air. The vectors present in the environment spread the microbial pathogens to short and/or long distances. Detection of microbial pathogens rapidly and reliably by employing suitable sensitive applicable for different ecosystems. The pathogens have to be identified precisely and differentiated and quantified to plan appropriate short- and long-term strategies to contain the incidence and spread of diseases induced by them. This book aims to present all relevant and latest information on the detection techniques based on the biological, biochemical, immunological and nucleic acid characteristics of microbial pathogens presents in the host plants, as well as in the natural substrates that support the survival and perpetuation of the pathogens.

Bacillus anthracis causes anthrax in all mammals, including humans. Depending upon the route of entry of B. anthracis spores, infection can result in cutaneous lesions, which are readily treatable with antibiotics, or systemic lethal disease, which is nearly always fatal. The continuing worldwide incidence of anthrax in animal populations, the risk of human infection associated with animal outbreaks, and the threat of use of B. anthracis as a biological weapon warrant continued investigation of this organisms and its virulence mechanims. Furthermore, B. anthracis is an excellent model system for inverstigation of virulence gene expression by bacteria.

Bacteria pathogenic for plants are responsible for devastating losses in agriculture. The use of antibiotics to control such infections is restricted in many countries due to worries over the evolution and transmission of antibiotic resistance. The advent of genome sequencing has enabled a better understanding, at the molecular level, of the strategies and mechanisms of pathogenesis, evolution of resistance to plant defense mechanisms, and the conversion of non-pathogenic into pathogenic bacteria. In this book, internationally acclaimed experts review the most important developments, providing an invaluable up-to-date summary of the molecular biology and genomics of plant pathogenic bacteria. The book opens with two chapters on bacterial evolution, diversity, and taxonomy - topics that have been transformed by molecular biology and genomics analyses. The third chapter delves into the crucially understudied area of pathogen adaptation to the plant apoplast environment. The next seven chapters focus on specific plant pathogens: Agrobacterium, Leifsonia, Pectobacterium, Pseudomonas, Ralstonia, Xanthomonas, and Xylella. The following four chapters review specific, intensively studied areas of research in the plant pathogen field: microbe associated molecular patterns (MAMPs) and innate immunity; use of bacterial virulence factors to suppress plant defense; cyclic di-GMP signalling and the regulation of virulence; and plasmids and the spread of virulence. The final chapter covers the critical area of bioinformatics. With contributions from some of the pioneering bacterial plant pathogen genome sequencers, this book is essential reading for every plant pathogen researcher - from the PhD student to the experienced scientist - as it provides a timely review of the current and most topical areas of research.

During the past twenty years, multitudes of exciting discoveries in the field of anaerobic bacteria have been made. BIOCHEMISTRY AND PHYSIOLOGY OF ANAEROBIC BACTERIA explores the full range of these microorganisms. Many anaerobes have been found to have the uniquely fascinating quality of being able to survive, indeed even thrive, in extreme environments. Anaerobic bacteria often do not require oxygen, can survive extremes in temperature, and can withstand the presence of toxins and heavy metals. In addition, these organisms have very different metabolic processes than "conventional" microorganisms. The wide diversity of metabolism in anaerobes is only part of the story. They have distinct energies, cytochromes, electron transport proteins, hydrogenases and dohydrogenases. Their molecular biology, physiology, and ability to use many types of electron receptors (CO2, sulfur, nitrogen and metal oxides) are also extraordinary. With practical applications ranging from wastewater treatment to food storage issues, clinical diagnosis and treatment of a wide range of medical conditions to decontamination of heavy metal exposures BIOCHEMISTRY AND PHYSIOLOGY OF ANAEROBIC BACTERIA will prove indispensable to researchers and students alike.

The bacterium Escherichia coli – E. coli for short – has long been the organism of choice for unraveling biochemical pathways, deciphering the genetic code, learning how DNA is replicated and read, and even for manufacturing proteins of commercial interest. For some thirty years, it also has been a model for studying the molecular biology of behavior. E. coli swims in a purposeful manner, propelled by long thin helical filaments, each driven at its base by a reversible rotary engine. As a microscopic organism immersed in an aqueous environment, it has mastered physical constraints utterly different from any that we know, devising sensors, comparators, and motors on the nanometer scale. This cross-disciplinary monograph describes these feats in a manner accessible to scientists, engineers, and others not trained in microbiology who would like to learn more about living machines. It treats the history of the subject, the physiology, physics, biochemistry and genetics, largely from first principles. It is all about a small but remarkably sophisticated friend who lives in your gut. Topics discussed include: How does E. coli move about? How do cells decide whether life is getting better or worse? What is the machinery that makes this behavior possible? How is the construction of this machinery programmed? How does this machinery work? What remains to be discovered?
