Book Description
This book elucidates the role of microbial genomic islands (GEIs) in genome stability, plasticity, evolutionary adaptation, and pathogenicity in the bacterial population. The initial chapters of the book present tools, including bioinformatics, artificial intelligence, machine learning, next-generation sequencing, and molecular biology techniques, for the analysis of the genomic islands. The book also discusses the importance of genomic islands in bacterial speciation, acquisition of genes related to resistome, nitrogen fixation, mobilomes, and nutritional fitness and adaptation. It provides recent advances in understanding microbial genomic islands' distribution, evolution, and mechanistic modes of behavior in pathogenic, non-pathogenic, and environmental species. This book is a valuable source for beginners in molecular microbiology, students, researchers, clinicians, stakeholders, and policymakers interested in understanding the role of GEIs in the adaptive evolution of microorganisms.

Book Description
Dr. Joshua Lederberg - scientist, Nobel laureate, visionary thinker, and friend of the Forum on Microbial Threats - died on February 2, 2008. It was in his honor that the Institute of Medicine's Forum on Microbial Threats convened a public workshop on May 20-21, 2008, to examine Dr. Lederberg's scientific and policy contributions to the marketplace of ideas in the life sciences, medicine, and public policy. The resulting workshop summary, Microbial Evolution and Co-Adaptation, demonstrates the extent to which conceptual and technological developments have, within a few short years, advanced our collective understanding of the microbiome, microbial genetics, microbial communities, and microbe-host-environment interactions.

Book Description
Advances in whole genome sequencing (WGS) technologies have created an era in which WGS can routinely be integrated into disease outbreak investigations for the rapid detection and characterization of the causative agents. Although most genomic investigations of outbreaks to date focus on using single nucleotide variations to help track the spread of disease, this dissertation focuses on efforts to improve the characterization of large clusters of horizontally-acquired genes, named genomic islands (GIs), that may cause large phenotypic changes. Such mobile elements contribute a fundamental role in the rapid adaptation of microbial life to various changes in the environment and are known to encode genes involved virulence, antimicrobial resistance (AMR) and alternative metabolism. I present the integration of rich gene annotations of virulence factors (VFs), AMR genes, and pathogen-associated genes into IslandViewer, a web server for the prediction of GIs in addition to the re-design of the web server to now include an interactive genome visualization library named GenomeD3Plot. I also present the application of IslandViewer for GI analysis on real outbreak data from multiple Listeria monocytogenes food-borne outbreaks from across Canada to show that isolates from geographically and temporally distinct outbreaks have unique sets of GIs. In addition, I present an analysis coupling the rich AMR gene annotations with GI predictions over a large collection of diverse microbial genera that revealed AMR genes as a whole are not over-represented within GIs, in contrast to VFs as have been previously studied. However, upon breaking down the dataset, certain classes of resistance were found to be associated with such mobile regions. Lastly, I present a WGS study of L. monocytogenes to elucidate the contribution of genetic changes to the ability of this pathogen to tolerate and grow in harsh environments, especially cold temperatures, that are important for its role in causing disease. Overall, this work contributes to improved characterization of GIs as well as a better understanding of trends in the role of GIs and mobile regions in the context of AMR and infectious disease.

Book Description
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.

Book Description
This open access book offers the first comprehensive account of the pan-genome concept and its manifold implications. The realization that the genetic repertoire of a biological species always encompasses more than the genome of each individual is one of the earliest examples of big data in biology that opened biology to the unbounded. The study of genetic variation observed within a species challenges existing views and has profound consequences for our understanding of the fundamental mechanisms underpinning bacterial biology and evolution. The underlying rationale extends well beyond the initial prokaryotic focus to all kingdoms of life and evolves into similar concepts for metagenomes, phenomes and epigenomes. The book’s respective chapters address a range of topics, from the serendipitous emergence of the pan-genome concept and its impacts on the fields of microbiology, vaccinology and antimicrobial resistance, to the study of microbial communities, bioinformatic applications and mathematical models that tie in with complex systems and economic theory. Given its scope, the book will appeal to a broad readership interested in population dynamics, evolutionary biology and genomics.

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
Genetics and Evolution of Infectious Diseases is at the crossroads between two major scientific fields of the 21st century: evolutionary biology and infectious diseases. The genomic revolution has upset modern biology and has revolutionized our approach to ancient disciplines such as evolutionary studies. In particular, this revolution is profoundly changing our view on genetically driven human phenotypic diversity, and this is especially true in disease genetic susceptibility. Infectious diseases are indisputably the major challenge of medicine. When looking globally, they are the number one killer of humans and therefore the main selective pressure exerted on our species. Even in industrial countries, infectious diseases are now far less under control than 20 years ago. The first part of this book covers the main features and applications of modern technologies in the study of infectious diseases. The second part provides detailed information on a number of the key infectious diseases such as malaria, SARS, avian flu, HIV, tuberculosis, nosocomial infections and a few other pathogens that will be taken as examples to illustrate the power of modern technologies and the value of evolutionary approaches. Takes an integrated approach to infectious diseases Includes contributions from leading authorities Provides the latest developments in the field
