Available in PDF, EPUB and Kindle. Book excerpt: Genetics and Evolution of Infectious Diseases, Third Edition discusses the evolving field of infectious diseases and their continued impact on the health of populations, especially in resource-limited areas of the world where they must confront the dual burden of death and disability due to infectious and chronic illnesses. Although substantial gains have been made in public health interventions for the treatment, prevention, and control of infectious diseases, in recent decades the world has witnessed the emergence of the human immunodeficiency virus (HIV) and the COVID-19 pandemic, increasing antimicrobial resistance, and the emergence of many new bacterial, fungal, parasitic, and viral pathogens. Fully updated and revised, this new edition presents the consequences of such diseases, the evolution of infectious diseases, the genetics of host-pathogen relationship, and the control and prevention strategies that are, or can be, developed. This book offers valuable information to biomedical researchers, clinicians, public health practitioners, decisions-makers, and students and postgraduates studying infectious diseases, microbiology, medicine, and public health that is relevant to the control and prevention of neglected and emerging worldwide diseases. - Takes an integrated approach to infectious diseases - Provides the latest developments in the field of infectious diseases - Focuses on the contribution of evolutionary and genomic studies for the study and control of transmissible diseases - Includes updated and revised contributions from leading authorities, along with six new chapters
Download or read book Microbial Pathogenomics written by Hilde de Reuse and published by Karger Medical and Scientific Publishers. This book was released on 2009-01-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: '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.

Download or read book Microbial Evolution and Co Adaptation written by Institute of Medicine and published by National Academies Press. This book was released on 2009-05-10 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Genomic Patterns of Pathogen Evolution Revealed by Comparison of Burkholderia Pseudomallei the Causative Agent of Melioidosis to Avirulent Burkholderia Thailandensis written by and published by . This book was released on 2006 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gram-negative bacterium Burkholderia pseudomallei (Bp) is the causative agent of the human disease melioidosis. To understand the evolutionary mechanisms contributing to Bp virulence, we performed a comparative genomic analysis of Bp K96243 and B. thailandensis (Bt) E264, a closely related but avirulent relative. RESULTS: We found the Bp and Bt genomes to be broadly similar, comprising two highly syntenic chromosomes with comparable numbers of coding regions (CDs), protein family distributions, and horizontally acquired genomic islands, which we experimentally validated to be differentially present in multiple Bt isolates. By examining species-specific genomic regions, we derived molecular explanations for previously-known metabolic differences, discovered potentially new ones, and found that the acquisition of a capsular polysaccharide gene cluster in Bp, a key virulence component, is likely to have occurred non-randomly via replacement of an ancestral polysaccharide cluster. Virulence related genes, in particular members of the Type III secretion needle complex, were collectively more divergent between Bp and Bt compared to the rest of the genome, possibly contributing towards the ability of Bp to infect mammalian hosts. An analysis of pseudogenes between the two species revealed that protein inactivation events were significantly biased towards membrane-associated proteins in Bt and transcription factors in Bp. CONCLUSIONS: Our results suggest that a limited number of horizontal-acquisition events, coupled with the fine-scale functional modulation of existing proteins, are likely to be the major drivers underlying Bp virulence. The extensive genomic similarity between Bp and Bt suggests that, in some cases, Bt could be used as a possible model system for studying certain aspects of Bp behavior.
Download or read book Genomic Epidemiology on the Frontline written by Allison G. B. Black and published by . This book was released on 2020 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within infectious disease epidemiology, genomic epidemiology is a field that seeks to describe pathogen transmission dynamics using evolutionary analysis of pathogen genome sequences and associated metadata. Genomic data have a wealth of information; we can use them to group related cases of disease, detect cryptic disease transmission, differentiate source and sink populations, and describe how introductions and sustained transmission contribute to an epidemic. In this dissertation I describe two genomic epidemiological studies of Zika virus, one in Colombia and the other in the United States Virgin Islands. I describe how each country's outbreak was shaped by regional seeding events and endemic transmission after introduction. These studies indicate differences in introduction frequency between the two countries, possibly related to the timing of their outbreaks and the number of other countries having concurrent outbreaks. In the last chapter, I describe recommendations for supporting open pathogen genomic analysis in public health agencies. These recommendations were developed from long-form interviews with public health agencies, and are designed to facilitate the development of genomic epidemiology outside of academia. Taken together, this body of work describes the application of genomic epidemiologic techniques and demonstrates possible strategies for operationalizing genomic surveillance.
Download or read book The Pangenome written by Hervé Tettelin and published by Springer Nature. This book was released on 2020-04-30 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Clonality written by John Avise and published by Oxford University Press. This book was released on 2008-10-23 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 99.9% of vertebrate species reproduce sexually. The exceptional 0.1% reproduce via asexual or clonal means, which vary wildly and are fascinating in their own right. In this book, John C. Avise describes the genetics, ecology, natural history, and evolution of the world's approximately 100 species of vertebrate animal that routinely display one form or another of clonal or quasi-clonal reproduction. By considering the many facets of sexual abstinence and clonal reproduction in vertebrate animals, Avise sheds new light on the biological meaning and ramifications of standard sexuality.
Download or read book The Applied Genomic Epidemiology Handbook written by Allison Black and published by CRC Press. This book was released on 2024-03-18 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Applied Genomic Epidemiology Handbook: A Practical Guide to Leveraging Pathogen Genomic Data in Public Health provides rationale, theory, and implementation guidance to help public health practitioners incorporate pathogen genomic data analysis into their investigations. During the SARS-CoV-2 pandemic, viral whole genome sequences were generated, analyzed, and shared at an unprecedented scale. This wealth of data posed both tremendous opportunities and challenges; the data could be used to support varied parts of the public health response but could be hard for much of the public health workforce to analyze and interpret, given a historical lack of experience working with pathogen genomic data. This book addresses that gap. Structured into eight wide-ranging chapters, this book describes how the overlapping timescales of pathogen evolution and infection transmission enable exploration of epidemiologic dynamics from pathogen sequence data. Different approaches to sampling and genomic data inclusion are presented for different types of epidemiologic investigations. To support epidemiologists in diving into pathogen genomic data analysis, this book also introduces the analytic tools and approaches that are readily used in public health departments and presents case studies to show step-by-step how genomic data are used and evaluated in disease investigations. Despite the breadth of scientific literature that uses pathogen genomic data to investigate disease dynamics, there remains little practical guidance to help applied epidemiologists build their ability to explore epidemiologic questions with pathogen genomic data. This handbook was written to serve as that guide. Including case studies, common methods, and software tools, this book will be of great interest to public health microbiologists or lab directors, bioinformaticians, epidemiologists, health officers, academics, as well as students working in a public health context.
Download or read book Paleogenomics written by Charlotte Lindqvist and published by Springer. This book was released on 2019-01-07 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in genome-scale DNA sequencing technologies have revolutionized genetic research on ancient organisms, extinct species, and past environments. When it is recoverable after hundreds or thousands of years of unintended preservation, “ancient DNA” (or aDNA) is often highly degraded, necessitating specialized handling and analytical approaches. Paleogenomics defines the field of reconstructing and analyzing the genomes of historic or long-dead organisms, most often through comparison with modern representatives of the same or similar species. The opportunity to isolate and study paleogenomes has radically transformed many fields, spanning biology, anthropology, agriculture, and medicine. Examples include understanding evolutionary relationships of extinct species known only from fossils, the domestication of plants and animals, and the evolution and geographical spread of certain pathogens. This pioneering book presents a snapshot view of the history, current status, and future prospects of paleogenomics, taking a broad viewpoint that covers a range of topics and organisms to provide an up-to-date status of the applications, challenges, and promise of the field. This book is intended for a variety of readerships, including upper-level undergraduate and graduate students, professionals and experts in the field, as well as anyone excited by the extraordinary insights that paleogenomics offers.
Download or read book Bacterial Genomes and Infectious Diseases written by Ricky V.L Chan and published by Springer Science & Business Media. This book was released on 2007-11-06 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first bacterial genome, Haemophilus influenzae, was completely sequenced, annotated, and published in 1995. Today, more than 200 prokaryotic (archaeal and bacterial) genomes have been completed and over 500 prokaryotic genomes are in va- ous stages of completion. Seventeen eukaryotic genomes plus four eukaryotic chro- somes have been completed. The concept of achieving better understanding of an organism through knowledge of the complete genomic sequence was first demonstrated in 1978 when the first bacteriophage genome, X174, was sequenced. Complete genomic sequences of prokaryotes have led to a better understanding of the biology and evolution of the microbes, and, for pathogens, facilitated identification of new vaccine candidates, putative virulence genes, targets for antibiotics, new strategy for rapid diagnosis, and investigation of bacteria–host interactions and disease mec- nisms. Recent increased interest in microbial pathogens and infectious diseases is largely attributed to the re-emergence of infectious diseases like tuberculosis, emergence of new infectious diseases like AIDS and severe acute respiratory syndrome, the problem of an increasing rate of emergence of antibiotic-resistant variants of pathogens, and the fear of bioterrorism. Microbes are highly diverse and abundant in the biosphere. Less than 1% of these morphologically identified microbes can be cultured in vitro using standard techniques and conditions. With such abundance of microbes in nature, we can expect to see new variants and new species evolve and a small number will emerge as pathogens to humans.
Download or read book Ecological Genomics written by Christian R. Landry and published by Springer Science & Business Media. This book was released on 2013-11-25 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers in the field of ecological genomics aim to determine how a genome or a population of genomes interacts with its environment across ecological and evolutionary timescales. Ecological genomics is trans-disciplinary by nature. Ecologists have turned to genomics to be able to elucidate the mechanistic bases of the biodiversity their research tries to understand. Genomicists have turned to ecology in order to better explain the functional cellular and molecular variation they observed in their model organisms. We provide an advanced-level book that covers this recent research and proposes future development for this field. A synthesis of the field of ecological genomics emerges from this volume. Ecological Genomics covers a wide array of organisms (microbes, plants and animals) in order to be able to identify central concepts that motivate and derive from recent investigations in different branches of the tree of life. Ecological Genomics covers 3 fields of research that have most benefited from the recent technological and conceptual developments in the field of ecological genomics: the study of life-history evolution and its impact of genome architectures; the study of the genomic bases of phenotypic plasticity and the study of the genomic bases of adaptation and speciation.
