Book Description
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.

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
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.

Book Description
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.

Book Description
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.

Book Description
This comprehensive study of poultry meat safety offers readers the most up-to-date information on food safety concerns in poultry meat production. Chapters address recent topics of interest such as organic poultry production, antimicrobial resistant pathogens in poultry, antibiotic usage in poultry production, and pre- and post- harvest approaches to improving poultry meat safety. The last couple of decades have observed a significant increase in poultry meat production in the US. However, poultry meat is a potential source of foodborne pathogens such as Salmonella, Campylobacter spp. and pathogenic Escherichia coli (APEC linked to human infections), leading to economic losses to the poultry industry and impacting public health. Advances in knowledge in microbiology, molecular biology, immunology and “omics” fields have intensified efforts to improve the microbiological safety of poultry by targeting virulence mechanisms of the pathogens, developing vaccines and improving gut health in chickens. Moreover, due to the emergence of multidrug resistance in poultry-borne pathogens, and growth of organic poultry production, there exists significant interest for developing natural strategies for controlling pathogens in chickens. This edited volume provides insight into these strategies and covers other material of interest to food microbiologists, public health personnel, and poultry scientists. Readers of various backgrounds will appreciate its incorporation of recent developments not covered in other publications on the subject.

Book Description
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.
