Download or read book Fighting Campylobacter Infections written by Steffen Backert and published by Springer Nature. This book was released on 2021-02-23 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume explores Campylobacter species, which are some of the most important foodborne pathogens. Above all, contaminated poultry meat can cause human gastroenteritis in both developed and developing countries. The respective contributions reveal how these infections can also increase the risk of generalized paralytic diseases such as Guillain-Barré syndrome, Miller-Fisher syndrome, and Chinese paralytic syndrome. Due to their influence on the nervous system, circulatory system, and various organs, Campylobacter infections represent a serious public health concern. Campylobacter can be effectively combated by addressing the hygienic conditions in both food production and human lifestyles. Accordingly, the authors put forward a One Health perspective, which provides readers with essential insights into the basic biology of Campylobacter, as well as practical guidance on aspects ranging from food production to the clinical treatment of infections. Chapters 'Population Biology and Comparative Genomics of Campylobacter Species' and 'Natural Competence and Horizontal Gene Transfer in Campylobacter' are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

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 About the Foodborne Pathogen Campylobacter written by Odile Tresse and published by Frontiers Media SA. This book was released on 2018-02-22 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: A significant increase in the prevalence of campylobacteriosis cases has been observed over the past years. Campylobacter has emerged as the leading cause of bacterial foodborne disease worldwide with a significant impact on human health and an associated economic burdens. Campylobacteriosis human cases have been generally correlated with the handling, preparation and consumption of poultry. In 2017, the European Commission regulation has amended Regulation (EC) No 2073/2005 on the hygiene of foodstuffs as regards Campylobacter on broiler carcasses stating a limit of 1000 cfu/g. Campylobacter is also present in other farm animals and is frequently found on a range of foodstuffs due to cross contamination. Among the pathogenic species, C. jejuni is the most prevalent species followed by C. coli. Current guidelines highlight the importance of biosecurity but these measures are failing to mitigate the risk of pathogenic Campylobacter. As an obligate microaerophile, Campylobacter does not multiply under atmospheric oxygen concentration at ambient temperatures. It therefore constitutes a puzzle as to how it can survive from farm to retail outlets. The underlying molecular mechanisms of persistence, survival and pathogenesis appear to be unique to this pathogen. Recent research has indicated how genomic polymorphism, restricted catabolic capacity, self regulation or deregulation of genes, bacterial cooperation and unknown contamination routes may be connected to this specificity. This book includes original studies on both C. jejuni and C. coli species dealing with epidemiology and animal carriage, host interaction, control strategies, metabolism and regulation specificities of these two pathogenic species, methodology to improve cultural techniques and chicken gut microbiota challenged with Campylobacter.
Download or read book Indicators for Waterborne Pathogens written by National Research Council and published by National Academies Press. This book was released on 2004-06-19 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Download or read book Achieving sustainable production of poultry meat Volume 1 written by Steven C. Ricke and published by Burleigh Dodds Science Publishing. This book was released on 2017-01-01 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: To meet growing demand, the FAO has estimated that world poultry production needs to grow by 2-3% per year to 2030. Much of the increase in output already achieved has been as a result of improvements in commercial breeds combined with rearing in more intensive production systems. However, more intensive systems and complex supply chains have increased the risk of rapid transmission of animal diseases and zoonoses. Consumer expectations of sensory and nutritional quality have never been higher. At the same time consumers are more concerned about the environmental impact of poultry production as well as animal welfare. Drawing on an international range of expertise, this book reviews research on safety, quality and sustainability issues in poultry production. Part 1 discusses risks from pathogens, detection and safety management on farms and in slaughterhouse operations. Part 2 looks at ways of enhancing the flavour, colour, texture and nutritional quality of poultry meat. Finally, the book reviews the environmental impact of poultry production. Achieving sustainable production of poultry meat Volume 1: Safety, quality and sustainability will be a standard reference for poultry and food scientists in universities, government and other research centres and companies involved in poultry production. It is accompanied by two further volumes which review poultry breeding, nutrition, health and welfare.
Download or read book Applied Genomics of Foodborne Pathogens written by Xiangyu Deng and published by Springer. This book was released on 2017-01-23 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a timely and thorough snapshot into the emerging and fast evolving area of applied genomics of foodborne pathogens. Driven by the drastic advance of whole genome shot gun sequencing (WGS) technologies, genomics applications are becoming increasingly valuable and even essential in studying, surveying and controlling foodborne microbial pathogens. The vast opportunities brought by this trend are often at odds with the lack of bioinformatics know-how among food safety and public health professionals, since such expertise is not part of a typical food microbiology curriculum and skill set. Further complicating the challenge is the large and ever evolving body of bioinformatics tools that can obfuscate newcomers to this area. Although reviews, tutorials and books are not in short supply in the fields of bioinformatics and genomics, until now there has not been a comprehensive and customized source of information designed for and accessible to microbiologists interested in applying cutting-edge genomics in food safety and public health research. This book fills this void with a well-selected collection of topics, case studies, and bioinformatics tools contributed by experts at the forefront of foodborne pathogen genomics research.
Download or read book Ending the War Metaphor written by Institute of Medicine and published by National Academies Press. This book was released on 2006-07-09 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infectious diseases have existed longer than us, as long as us, or are relatively newer than us. It may be the case that a disease has existed for many, many years but has only recently begun affecting humans. At the turn of the century the number of deaths caused by infections in the United States had been falling steadily but since the '80s has seen an increase. In the past 30 years alone 37 new pathogens have been identified as human disease threats and 12% of known human pathogens have been classified as either emerging or remerging. Whatever the story, there is currently a "war" on infectious diseases. This war is simply the systematic search for the microbial "cause" of each disease, followed by the development of antimicrobial therapies. The "war" on infectious diseases, however, must be revisited in order to develop a more realistic and detailed picture of the dynamic interactions among and between host organisms and their diverse populations of microbes. Only a fraction of these microbes are pathogens. Thus, in order to explore the crafting of a new metaphor for host-microbe relationships, and to consider how such a new perspective might inform and prioritize biomedical research, the Forum on Microbial Threats of the Institute of Medicine (IOM) convened the workshop, Ending the War Metaphor: The Changing Agenda for Unraveling the Host-Microbe Relationship on March 16-17, 2005. Workshop participants examined knowledge and approaches to learning about the bacterial inhabitants of the human gut, the best known host-microbe system, as well as findings from studies of microbial communities associated with other mammals, fish, plants, soil, and insects. The perspective adopted by this workshop is one that recognizes the breadth and diversity of host-microbe relationships beyond those relative few that result in overt disease. Included in this summary are the reports and papers of individuals participating in the Forum as well as the views of the editors.
Download or read book The Prokaryotes written by Edward F. DeLong and published by Springer. This book was released on 2014-09-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. 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. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea
Download or read book Big Farms Make Big Flu written by Rob Wallace and published by NYU Press. This book was released on 2016-06-30 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first collection to explore infectious disease, agriculture, economics, and the nature of science together Thanks to breakthroughs in production and food science, agribusiness has been able to devise new ways to grow more food and get it more places more quickly. There is no shortage of news items on hundreds of thousands of hybrid poultry—each animal genetically identical to the next—packed together in megabarns, grown out in a matter of months, then slaughtered, processed and shipped to the other side of the globe. Less well known are the deadly pathogens mutating in, and emerging out of, these specialized agro-environments. In fact, many of the most dangerous new diseases in humans can be traced back to such food systems, among them Campylobacter, Nipah virus, Q fever, hepatitis E, and a variety of novel influenza variants. Agribusiness has known for decades that packing thousands of birds or livestock together results in a monoculture that selects for such disease. But market economics doesn't punish the companies for growing Big Flu—it punishes animals, the environment, consumers, and contract farmers. Alongside growing profits, diseases are permitted to emerge, evolve, and spread with little check. “That is,” writes evolutionary biologist Rob Wallace, “it pays to produce a pathogen that could kill a billion people.” In Big Farms Make Big Flu, a collection of dispatches by turns harrowing and thought-provoking, Wallace tracks the ways influenza and other pathogens emerge from an agriculture controlled by multinational corporations. Wallace details, with a precise and radical wit, the latest in the science of agricultural epidemiology, while at the same time juxtaposing ghastly phenomena such as attempts at producing featherless chickens, microbial time travel, and neoliberal Ebola. Wallace also offers sensible alternatives to lethal agribusiness. Some, such as farming cooperatives, integrated pathogen management, and mixed crop-livestock systems, are already in practice off the agribusiness grid. While many books cover facets of food or outbreaks, Wallace's collection appears the first to explore infectious disease, agriculture, economics and the nature of science together. Big Farms Make Big Flu integrates the political economies of disease and science to derive a new understanding of the evolution of infections. Highly capitalized agriculture may be farming pathogens as much as chickens or corn.
Download or read book Management of Legionella in Water Systems written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-02-20 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
Download or read book Role of Birds in Transmitting Zoonotic Pathogens written by Yashpal Singh Malik and published by Springer Nature. This book was released on 2022-01-01 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zoonotic diseases pose a serious threat to global health and economy. Domestic and wild birds play crucial roles in transmission and spread of important zoonotic pathogens, with significant implications on human and avian health. Although zoonotic diseases have been extensively studied, information on various aspects of avian zoonotic pathogens have not been revisited or revised to any great extent. This book is a comprehensive and updated compilation of important zoonotic diseases that are transmitted by domestic and wild birds, and consists of 21 chapters that meticulously describe the (i) etiology and evolution, (ii) complex epidemiology, such as migration pathways in context of disease transmission, (iii) pathogenesis, (iv) clinical signs and necropsy findings, (v) diagnostics including latest molecular assays, and (vi) preventative and control strategies, with an emphasis on therapeutics and prophylaxis, of important zoonotic pathogens (bacterial, fungal, parasitic and viral) of avian origin in humans and birds. Each chapter is aptly supported by interactive tables and figures, and features an updated reference section. This book aims to create awareness and enlighten students of veterinary and human medicine on the role of birds in zoonoses, and would serve as a useful reference for working veterinarians, human doctors, and public health experts.
