Our understanding of bacterial genetics has progressed as the genomics field has advanced. Genetics and genomics complement and influence each other; they are inseparable. Under the novel insights from genetics and genomics, once-believed borders in biology start to fade: biological knowledge of the bacterial world is being viewed under a new light and concepts are being redefined. Species are difficult to delimit and relationships within and between groups of bacteria – the whole concept of a tree of life – is hotly debated when dealing with bacteria. The DNA within bacterial cells contains a variety of features and signals that influence the diversity of the microbial world. This text assumes readers have some knowledge of genetics and microbiology but acknowledges that it can be varied. Therefore, the book includes all of the information that readers need to know in order to understand the more advanced material in the book.

Understanding of bacterial genetics and genomics is fundamental to understanding bacteria and higher organisms, as well. Novel insights in the fields of genetics and genomics are challenging the once clear borders between the characteristics of bacteria and other life. Biological knowledge of the bacterial world is being viewed under a new light with input from genetic and genomics. Replication of bacterial circular and linear chromosomes, coupled (and uncoupled) transcription and translation, multiprotein systems that enhance survival, wide varieties of ways to control gene and protein expression, and a range of other features all influence the diversity of the microbial world. This text acknowledges that readers have varied knowledge of genetics and microbiology. Therefore, information is presented progressively, to enable all readers to understand the more advanced material in the book. This second edition of Bacterial Genetics and Genomics updates the information from the first edition with advances made over the past five years. This includes descriptions for 10 types of secretion systems, bacteria that can be seen with the naked eye, and differences between coupled transcription-translation and the uncoupled runaway transcription in bacteria. Topic updates include advances in bacteriophage therapy, biotechnology, and understanding bacterial evolution. Key Features Genetics, genomics, and bioinformatics integrated in one place Over 400 full-colour illustrations explain concepts and mechanisms throughout and are available to instructors for download A section dedicated to the application of genetics and genomics techniques, including a chapter devoted to laboratory techniques, which includes useful tips and recommendations for protocols, in addition to troubleshooting and alternative strategies Bulleted key points summarize each chapter Extensive self-study questions related to the chapter text and several discussion topics for study groups to explore further This book is extended and enhanced through a range of digital resources that include: Interactive online quizzes for each chapter Flashcards that allow the reader to test their understanding of key terms from the book Useful links for online resources associated with Chapters 16 and 17

Overview and Goals This book describes how to visualize and compare bacterial genomes. Sequencing technologies are becoming so inexpensive that soon going for a cup of coffee will be more expensive than sequencing a bacterial genome. Thus, there is a very real and pressing need for high-throughput computational methods to compare hundreds and thousands of bacterial genomes. It is a long road from molecular biology to systems biology, and in a sense this text can be thought of as a path bridging these ? elds. The goal of this book is to p- vide a coherent set of tools and a methodological framework for starting with raw DNA sequences and producing fully annotated genome sequences, and then using these to build up and test models about groups of interacting organisms within an environment or ecological niche. Organization and Features The text is divided into four main parts: Introduction, Comparative Genomics, Transcriptomics and Proteomics, and ? nally Microbial Communities. The ? rst ? ve chapters are introductions of various sorts. Each of these chapters represents an introduction to a speci? c scienti? c ? eld, to bring all readers up to the same basic level before proceeding on to the methods of comparing genomes. First, a brief overview of molecular biology and of the concept of sequences as biological inf- mation are given.

A wide range of microbiologists, molecular biologists, and molecular evolutionary biologists will find this new volume of singular interest. It summarizes the present knowledge about the structure and stability of microbial genomes, and reviews the techniques used to analyze and fingerprint them. Maps of approximately thirty important microbes, along with articles on the construction and relevant features of the maps are included. The volume is not intended as a complete compendium of all information on microbial genomes, but rather focuses on approaches, methods and good examples of the analysis of small genomes.

'Microbial Pathogenomics' contains a unique collection of reviews demonstrating how genomics has revolutionized our understanding of virulence, host-adaptation strategies and the evolution of bacterial pathogens. Current technologies - computational tools and functional approaches to genome analysis - are carefully documented and clearly illustrated. These include visualization tools for genome comparison, databases, in silico metabolic reconstructions and function prediction as well as interactomics for the study of protein-protein interactions. The concepts of pan-genomics and reverse vaccinology are introduced as strategies when addressing the challenge presented by bacterial diversity in the prevention and treatment of infectious diseases. The authors explore individual bacterial pathogens and discuss the mechanisms that have contributed to their evolutionary success. Special cases of host adaptation, for example, are illustrated by Helicobacter pylori and 'Mycobacterium tuberculosis' which are human-specific and highly persistent; further bacteria discussed include 'Escherichia coli, Campylobacter, Pseudomonas, Legionella, Bartonella, Burkholderia' and 'Staphylococcus'.'Microbial Pathogenomics' provides the reader with a global view of key aspects and future trends in bacterial pathogenomics and evaluates their impact on the understanding and treatment of infectious diseases. Well illustrated and accessible to both specialists and nonspecialists, it is recommended not only for researchers in microbiology, genomics and biotechnology, but also for lecturers and teachers.

Although we can't usually see them, microbes are essential for every part of human life-indeed all life on Earth. The emerging field of metagenomics offers a new way of exploring the microbial world that will transform modern microbiology and lead to practical applications in medicine, agriculture, alternative energy, environmental remediation, and many others areas. Metagenomics allows researchers to look at the genomes of all of the microbes in an environment at once, providing a "meta" view of the whole microbial community and the complex interactions within it. It's a quantum leap beyond traditional research techniques that rely on studying-one at a time-the few microbes that can be grown in the laboratory. At the request of the National Science Foundation, five Institutes of the National Institutes of Health, and the Department of Energy, the National Research Council organized a committee to address the current state of metagenomics and identify obstacles current researchers are facing in order to determine how to best support the field and encourage its success. The New Science of Metagenomics recommends the establishment of a "Global Metagenomics Initiative" comprising a small number of large-scale metagenomics projects as well as many medium- and small-scale projects to advance the technology and develop the standard practices needed to advance the field. The report also addresses database needs, methodological challenges, and the importance of interdisciplinary collaboration in supporting this new field.

Over the past several decades, new scientific tools and approaches for detecting microbial species have dramatically enhanced our appreciation of the diversity and abundance of the microbiota and its dynamic interactions with the environments within which these microorganisms reside. The first bacterial genome was sequenced in 1995 and took more than 13 months of work to complete. Today, a microorganism's entire genome can be sequenced in a few days. Much as our view of the cosmos was forever altered in the 17th century with the invention of the telescope, these genomic technologies, and the observations derived from them, have fundamentally transformed our appreciation of the microbial world around us. On June 12 and 13, 2012, the Institute of Medicine's (IOM's) Forum on Microbial Threats convened a public workshop in Washington, DC, to discuss the scientific tools and approaches being used for detecting and characterizing microbial species, and the roles of microbial genomics and metagenomics to better understand the culturable and unculturable microbial world around us. Through invited presentations and discussions, participants examined the use of microbial genomics to explore the diversity, evolution, and adaptation of microorganisms in a wide variety of environments; the molecular mechanisms of disease emergence and epidemiology; and the ways that genomic technologies are being applied to disease outbreak trace back and microbial surveillance. Points that were emphasized by many participants included the need to develop robust standardized sampling protocols, the importance of having the appropriate metadata, data analysis and data management challenges, and information sharing in real time. The Science and Applications of Microbial Genomics summarizes this workshop.

Over 500 prokaryotic genomes have been sequenced to date, and thousands more have been planned for the next few years. While these genomic sequence data provide unprecedented opportunities for biologists to study the world of prokaryotes, they also raise extremely challenging issues such as how to decode the rich information encoded in these genomes. This comprehensive volume includes a collection of cohesively written chapters on prokaryotic genomes, their organization and evolution, the information they encode, and the computational approaches needed to derive such information. A comparative view of bacterial and archaeal genomes, and how information is encoded differently in them, is also presented. Combining theoretical discussions and computational techniques, the book serves as a valuable introductory textbook for graduate-level microbial genomics and informatics courses.

Presents an integrated view of the expression of bacterial genetic information, genome architecture and function, and bacterial physiology and pathogenesis This book blends information from the very latest research on bacterial chromosome and nucleoid architecture, whole-genome analysis, cell signaling, and gene expression control with well-known gene regulation paradigms from model organisms (including pathogens) to give readers a picture of how information flows from the environment to the gene, modulating its expression and influencing the competitive fitness of the microbe. Structure and Function of the Bacterial Genome explores the governance of the expression of the genes that make a bacterium what it is, and updates the basics of gene expression control with information about transcription promoter structure and function, the role of DNA as a regulatory factor (in addition to its role as a carrier of genetic information), small RNAs, RNAs that sense chemical signals, ribosomes and translation, posttranslational modification of proteins, and protein secretion. It looks at the forces driving the conservation and the evolution of the dynamic genome and offers chapters that cover DNA replication, DNA repair, plasmid biology, recombination, transposition, the roles of repetitive DNA sequences, horizontal gene transfer, the defense of the genome by CRISPR-Cas, restriction enzymes, Argonaute proteins and BREX systems. The book finishes with a chapter that gives an integrated overview of genome structure and function. Blends knowledge of gene regulatory mechanisms with a consideration of nucleoid structure and dynamics Offers a 'DNA-centric' approach to considering transcription control Views horizontal gene transfer from a gene regulation perspective Assesses the opportunities and limitations of designing synthetic microbes or rewiring existing ones Structure and Function of the Bacterial Genome is an ideal book for graduate and undergraduate students studying microbial cell biology, bacterial pathogenesis, gene regulation, and molecular microbiology. It will also appeal to principal investigators conducting research on these and related topics and researchers in synthetic biology and other arms of biotechnology.

The genetic information contained in DNA is not static, especially in bacterial DNA. It is capable of recombining with other DNA sequences and transferring to other bacteria. These processes allow bacteria to rapidly respond to their environment and are also important in production of disease and the spread of antibiotic resistance. This book is concerned with the mechanisms underlying these dynamic processes in bacterial DNA.

Foodborne illnesses caused by various bacterial, viral, and fungal pathogens lead to a high number of morbidity and mortality in the U.S. and throughout the world. Recent advances in microbial genomics have significantly improved our understanding of the physiology, evolution, ecology, epidemiology, and pathogenesis of different foodborne pathogens. This book focuses on the genomics of foodborne bacterial pathogens. It begins with a brief overview of the recent advances in microbial genomics and the impact of genomics on food safety research. Then, eight chapters follow that elaborate some in-depth reviews on the genomics of several common foodborne bacterial pathogens including Bacillus, Campylobacter, Clostridium, Escherichia coli, Listeria, Salmonella, Staphylococcus, and Vibrio. Finally, the last four chapters focus on some current genomic, transcriptomic, and proteomic technologies and their applications in studying the epidemiology, evolution, and pathogenesis of foodborne bacterial pathogens. Genomics of Foodborne Bacterial Pathogens can be used as a reference by scientists and professionals in academia, government, and industry who are interested in understanding microbial genomics and using genomics tools to study foodborne bacterial pathogens. This book can also be used as a textbook for instructors and professors who teach food microbiology or microbial genomics-related courses at the post-graduate level.
