Bacterial surface or secreted polysaccharides are molecules that can function as barriers to protect bacterial cells against environmental stresses, as well as act as adhesins or recognition molecules. In some cases, these molecules are immunodominant antigens eliciting a vigorous immune response, while in other cases the expression of polysaccharides camouflages the bacteria from the immune system. Until recently, most studies on the enzymatic steps and regulation of these molecules were performed on the enteric gram negative bacteria Escherichia coli and Salmonella typhimurium. With the advent of modern bacterial genetics, techniques such as construction and characterization of polysaccharide mutants, cloning of genes and complementation of these mutations, and expression of polysaccharides in heterologous bacterial hosts has prompted investigations into the roles and functions of these molecules for many different bacteria. Here, we present the genetic analysis of polysaccharides from a number of bacteria pathogenic to humans and one symbiotic with plants in hopes that similarities in the experimental approaches as well as finding s from such investigations may lead to a general understanding of polysaccharide synthesis and regulation in various bacteria.

Alkali Cation Transport Systems in Prokaryotes is the first book that brings together the physiological, structural, and molecular biological aspects of the transport of sodium, potassium, and ammonium across the bacterial cell membrane. Sodium translocation plays a major role in energy coupling of some prokaryotes, and much of the book is devoted to new and exciting developments in this field. Over 30 experts have contributed to this excellent reference for microbiologists, biochemists, molecular biologists, cell biologists, chemotherapists, and researchers interested in bioenergetics.

The increasing resistance of bacteria to antibiotics, and pests to pesticides, threatens to undo some of the most remarkable advances made in public health and agriculture during the past century. Though the potential consequences of increased antibiotic and pesticide resistance are far reaching, regulatory efforts to address the problem are at a very early stage. Battling Resistance to Antibiotics and Pesticides moves such discussions forward by presenting cutting edge research and the first comprehensive application of economic tools to analyze how antibiotics and pesticides should be used to maximize their value to society. Laxminarayan and his contributors explore lessons from past experiences with resistance, especially in agriculture. They consider what incentives would be ideal for the individuals who prescribe or apply antibiotics and pesticides, and what would be ideal for the firms engaged in developing and producing these products. The chapters in this groundbreaking book reflect the fact that efforts to combat resistance will require contributions from a broad range of scholars and professionals, representing a broad range of expertise. The analysis demonstrates that, for all these participants, an understanding of economic issues is an essential complement to knowledge of medical or biological factors. The book provides economists with an overview of relevant scientific issues, as well as a variety of analytical approaches to studying the economics of resistance. It offers policymakers detailed analyses of the multiple dimensions of resistance and discusses the future strategies to combat and manage resistance. For professionals in medicine, public health, and agriculture, the book translates the economic approaches into usable guidance for daily practice and decisionmaking.

This first major reference work dedicated to the mannifold industrial and medical applications of bacteriophages provides both theoretical and practical insights into the emerging field of bacteriophage biotechnology. The book introduces to bacteriophage biology, ecology and history and reviews the latest technologies and tools in bacteriophage detection, strain optimization and nanotechnology. Usage of bacteriophages in food safety, agriculture, and different therapeutic areas is discussed in detail. This book serves as essential guide for researchers in applied microbiology, biotechnology and medicine coming from both academia and industry.

"The Prokaryotes" is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Archaea. This fourth edition of "The Prokaryotes" is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of "The Prokaryotes" is the most complete resource on the biology of prokaryotes.

This volume is designed to be a resource of proven techniques and approaches for probing the activities of bacterial, eukaryotic, and archaeal RNA polymerases. This book features a collection of in vitro and in vivo technologies that will permit researchers to purify and probe the position and stability of RNA polymerase complexes at different points of the transcription cycle, analyze the various translocations and intermolecular movements associated with catalysis, define recruitment strategies, probe the roles of transcription factors in each stage of the cycle, highlight conserved and disparate fidelity mechanisms, analyze the resultant transcripts, and study coordination of the nascent mRNA synthesis by the RNA polymerase and mRNA translation by the ribosome. Written in the highly successful Methods of Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubles troubleshooting and avoiding known pitfalls. Practical and timely, Bacterial Transcriptional Controls: Methods and Protocols highlights the breadth and depth of techniques that are likely to continue shaping the transcription community in the future.
