Book Description
The Molecular Biology of the Bacilli, Volume I: Bacillus subtilis focuses on areas of research traditionally investigated in Bacillus subtilis, as well as topics in which outstanding progress has been made. It discusses the sporulation, defective bacteriophage, and transformation of Bacillus subtilis. Organized into 11 chapters, the book begins with the genetic map of Bacillus subtilis, followed by DNA replication and RNA polymerase of the said species. The book then describes the translational apparatus of Bacillus subtilis. It also explains the genetic transformation in Bacillus subtilis; the sporulation genes; the regulatory mechanisms in the development of lytic bacteriophages in this species; the temperate Bacillus subtilis phages; the specialized transduction in Bacillus subtilis; and molecular cloning in this organism. Lastly, the book considers the most economically important areas of the microbiological industry employing bacilli, including the production of enzymes, nucleosides, riboflavin, and preparations pathogenic to insects. This book will be useful to scientists who are concerned with the use of Bacillus subtilis as a tool for the study of molecular biology and to those who wish to increase the medical, veterinary, and industrial usefulness of this and related organisms.

Book Description
Molecular Biological Methods for Bacillus Edited by C. R. Harwood, Department of Microbiology, University of Newcastle upon Tyne, UK and S. M. Cutting, The Biological Laboratories, Harvard University, USA This volume represents the first major attempt to produce a compendium of the experimental methods used for the analysis of Bacillus, one of the most important procaryotic genera. Since the pioneering work on the transformation and genetic analysis of Bacillus subtilis by John Spizizen and his colleagues in the late 1950s this microorganism has been extensively studied and is now one of the best understood. More than forty of the world’s leading researchers in the field have generously contributed experimental procedures—devised and used in their laboratories—to this book. The aim throughout has been to present methods as simple step-by-step protocols which have been thoroughly tried and tested. The context in which the methods are used is discussed in detail and relevant information provided on the physiology and genetics of Bacillus. In addition valuable support is provided in the form of troubleshooting tips and advice on safety, the preparation of reagents, and the use of equipment. The book will be invaluable to those working with the genus Bacillus and related genera—both established researchers and those wishing to use this important microorganism for the first time.

Book Description
Molecular Cloning and Gene Regulation in Bacilli presents the proceedings of the 1981 Cetus Conference on Genetics held at Stanford University, Stanford, California. It summarizes both basic and applied aspects of bacilli genetics. It discusses significant advances made in understanding chromosome structure, gene arrangement, molecular cloning, cloned gene expression, DNA metabolism, transcription, and translation. Divided into five sessions, the book starts by discussing the DNA sequence from RNA intergenic spaces of Bacillus subtilis rRNA gene sets, the construction of a bifunctional cosmid vector of large DNA segments, and the mating system of bacilli. Molecular cloning session covers complementation system and dominance analyses in Bacillus, genetic fusion of Escherichia coli lac genes to a Bacillus subtilis promoter, and DNA cloning of B. subtilis. It also describes the construction of trimethoprim resistant B. subtilis plasmid and expression of E. coli trp genes cloned in B. subtilis. Session III encompasses chapters that discuss protein secretion by bacilli; regulation of alpha-amylase production in B. subtilis; entomocidal toxin translation of B. thuringiensis; and expression of crystal protein, heterologous, and eukaryotic genes in bacilli. Session IV focuses on various aspects of DNA metabolism of bacilli, such as the interaction of bacterial chromosome with cell membrane; plasmid DNA in competent cells and protoplasts of B. subtilis; analysis of peptides synthesized by B. subtilis mutants; and DNA repair, uptake, restriction, modification, and recombination. The final session examines species-specific translation, control of gene expression and replications in plasmids, development of expression-vector in B. subtilis, and regulatory modifications of RNA polymerase. Each chapter is presented in an experimental manner, consisting of a summary of the study, materials and methods, results, as well as references.

Book Description
Can today's innovative practices and molecular tools tame this ancient disease? One third of the world's population is infected with tuberculosis (TB), with about 10 million new cases annually. To combat TB and its agent, Mycobacterium tuberculosis, the World Health Organization launched The End TB Strategy, which aims to slash the suffering and cost of TB by 2035. This makes the second edition of Tuberculosis and the Tubercle Bacillus, edited by Jacobs, McShane, Mizrahi, and Orme, an extremely valuable resource for scientists and clinicians. The editors have gathered their colleagues from around the world to present the latest on the molecular biology of M. tuberculosis and related species, the host-pathogen interactions that enable invasion, and the host's immune response to M. tuberculosis infection. The basic, clinical, and translational research presented in this book supports the goals of WHO's End TB Strategy by driving toward the development of effective vaccines, rapid molecular diagnostics, and anti-TB drugs. Creating an effective tuberculosis vaccine. Understand the innate and adaptive immune response to M. tuberculosis infection, its study in established animal models, and how this information is being used to develop new vaccines against TB. Formulating new antituberculosis drugs. Learn the challenges and methods for evaluating new drugs in preclinical trials with a focus on drugs that work against "persisters" and those that act on the electron transport complex and ATP synthase of M. tuberculosis. Overcoming the challenges of diagnosing tuberculosis. Review new diagnostic tools that are simple, rapid, affordable, specific, sensitive, and safe, including molecular-based diagnostic methods such as GeneXpert MTB/RIF. Using molecular, genomic, and bioinformatics tools to understand the biology and evolution of Mycobacterium. Explore current research on the molecular mechanisms that M. tuberculosis uses to evade the immune system, enter a state of nonreplicating persistence, and become reactivated. The second edition of Tuberculosis and the Tubercle Bacillus presents the latest research on a microorganism that is exquisitely well adapted to its human host. This pathogen continues to confound scientists, clinicians, and public health specialists, who will all find much valuable information in this comprehensive set of reviews.

Book Description
Molecular Basis of Bacterial Pathogenesis focuses on the molecular mechanism of disease associated with bacterial pathogens. Topics covered include the population genetics of bacterial pathogenesis; environmental modulation of gene expression in gram-negative pathogens; and bacterial invasion and intracellular growth. Bacterial toxins are also discussed. This volume is comprised of 20 chapters and begins with an overview of pathogenesis, paying particular attention to common elements and genetic mechanisms of regulation. The discovery that many bacterial pathogens are clonal, with individual clones often having a greater virulence than others, is then considered. The next section deals with the regulation of synthesis of surface components and their role in colonization of the host and/or evasion of the host immune defense systems; antigenic variation and its role in evasion of the host immune response; and the role of iron acquisition systems in the colonization of the host. Subsequent chapters explore the invasion and intracellular growth of facultative and obligate intracellular parasites. The last section is devoted to studies on the role of bacterial toxic products in pathogenesis. Bacterial lipopolysaccharides (endotoxins) and exotoxins are described. This book should be of interest to molecular biologists, physiologists, clinical specialists, pathologists, and geneticists.

Book Description
This book describes the structures and functions of active protein filaments, found in bacteria and archaea, and now known to perform crucial roles in cell division and intra-cellular motility, as well as being essential for controlling cell shape and growth. These roles are possible because the cytoskeletal and cytomotive filaments provide long range order from small subunits. Studies of these filaments are therefore of central importance to understanding prokaryotic cell biology. The wide variation in subunit and polymer structure and its relationship with the range of functions also provide important insights into cell evolution, including the emergence of eukaryotic cells. Individual chapters, written by leading researchers, review the great advances made in the past 20-25 years, and still ongoing, to discover the architectures, dynamics and roles of filaments found in relevant model organisms. Others describe one of the families of dynamic filaments found in many species. The most common types of filament are deeply related to eukaryotic cytoskeletal proteins, notably actin and tubulin that polymerise and depolymerise under the control of nucleotide hydrolysis. Related systems are found to perform a variety of roles, depending on the organisms. Surprisingly, prokaryotes all lack the molecular motors associated with eukaryotic F-actin and microtubules. Archaea, but not bacteria, also have active filaments related to the eukaryotic ESCRT system. Non-dynamic fibres, including intermediate filament-like structures, are known to occur in some bacteria.. Details of known filament structures are discussed and related to what has been established about their molecular mechanisms, including current controversies. The final chapter covers the use of some of these dynamic filaments in Systems Biology research. The level of information in all chapters is suitable both for active researchers and for advanced students in courses involving bacterial or archaeal physiology, molecular microbiology, structural cell biology, molecular motility or evolution. Chapter 3 of this book is open access under a CC BY 4.0 license.

Book Description
was the result of the efforts of Robert Cleverdon. The rapidly developing discipline of molecular biology and the rapidly expanding knowledge of the PPLO were brought together at this meeting. In addition to the PPLO specialists, the conference invited Julius Marmur to compare PPLO DNA to DNA of other organisms; David Garfinkel, who was one of the first to develop computer models of metabolism; Cyrus Levinthal to talk about coding; and Henry Quastler to discuss information theory constraints on very small cells. The conference was an announcement of the role of PPLO in the fundamental understanding of molecular biology. Looking back 40-some years to the Connecticut meeting, it was a rather bold enterprise. The meeting was international and inter-disciplinary and began a series of important collaborations with influences resonating down to the present. If I may be allowed a personal remark, it was where I first met Shmuel Razin, who has been a leading figure in the emerging mycoplasma research and a good friend. This present volume is in some ways the fulfillment of the promise of that early meeting. It is an example of the collaborative work of scientists in building an understanding of fundamental aspects of biology.

Book Description
Megaplasmids are extrachromosomal genetic elements in the size range of 100 kb and larger. They are found in physiologically and phylogenetically diverse groups of bacteria and archaea. By definition, megaplasmids are not essential for the viability of their hosts under all growth conditions, but paradoxically many megaplasmids carry the genetic information for the defining and characteristic traits of the organism in which they reside. Microbial Megaplasmids reviews our knowledge of the extensively studied representatives, such as the catabolic plasmids of the pseudomonads, the rhizobial Sym plasmids, the Ti plasmids of the genus Agrobacterium and the giant enterobacterial virulence plasmids. It also presents snapshots of more recently discovered megaplasmids. The contribution of megaplasmids to the biology of their hosts is described, highlighting the interactions between megaplasmid and chromosomal genes.
