Book excerpt: Enteropathogenic and enterohemorrhagic E. coli are important causes of gastrointestinal disease worldwide. As part of their pathogenesis, EPEC and EHEC cause a distinctive lesion on the intestinal mucosa known as an attaching and effacing (A/E) lesion. A/E lesion formation requires a type III secretion system that injects multiple effector proteins into the cell. Despite their shared mechanism of intestinal colonization, EPEC and EHEC exhibit substantial differences in epidemiology and clinical disease. In particular, EHEC produces a potent Shiga toxin that is associated with development of the haemolytic uremic syndrome (HUS), an acute form of renal failure. This Research Topic will examine interactions between attaching and effacing bacteria and the host cell, and discuss EPEC/EPEC ecology, genomics and animal models of disease. Articles will centre on pathogen evolution, novel adhesins, type III effector biology and bacterium-host responses during infection.

Book excerpt: Although most strains of E. coli bacteria are harmless and live in the intestines of healthy humans and animals, several strains can produce powerful toxins and cause severe illness in humans. This versatile pathogen is best known for being transmitted to humans through contaminated foods — such as undercooked meat and unpasteurized fruit juice — and has attracts much attention when serious outbreaks occur. E. coli is capable of causing a wide variety of diseases — from urinary tract infections to meningitis. A considerable amount of media coverage has recently been devoted to one particular strain of E. coli, responsible for an estimated 73,000 cases of infection and 61 deaths in the United States each year. Knowing more about the biology, the evolution, and the genetic basis of this pathogen is crucial to future prevention of infection and illness. Pathogenic E. coli is a unique, comprehensive analysis of the biology and molecular mechanisms that enable this ubiquitous organism to thrive. Leading investigators in the field discuss the molecular basis of E. coli pathogenesis followed by chapters on genomics and evolution. Detailed descriptions of distinct strains reveal the molecular pathogenesis of each and the causes of intestinal and extra-intestinal infections in humans. Pathogenic E. coli concludes with a presentation of virulance factors, common to two or more pathotypes. This unique collection presents timely and vital information on understanding the inner workings of E. coli, which will lend key insights into disease prevention research.

Available in PDF, EPUB and Kindle. Book excerpt: Why do bacteria cause disease in humans? Is disease adaptive for the pathogen or just a biological accident? And if disease is adaptive, how does it influence the long-term or short-term fitness for the pathogen and how is it sustained in nature? In this chapter we try to address these questions by dissecting the molecular mechanisms of both pathogenicity and evolution of Escherichia coli, one of the most notorious and versatile human pathogens, which is also one of the most common human commensal bacteria. We examine how and, more importantly, why horizontally transferred virulence factors and pathoadaptive mutations are acquired by and sustained by certain E. coli lineages. The evolution of pathogenicity is thus reviewed from the perspective of E. coli ecology, with the discussion of various models of virulence evolution in general and some of its paradoxes. We hope to shed light from the evolutionary perspective on how professional, accidental, or opportunistic pathogens might be defined.

Available in PDF, EPUB and Kindle. Book excerpt: Bacterial diarrheal diseases remain an important leading cause of preventable death, especially among children under five in developing countries. In the American continent, diarrheal disease and other health complications caused by Escherichia coli constitute a major public health problem, and, therefore, several research groups have dedicated their effort to understand this pathogen and provide feasible solutions to prevent, treat and reduce E. coli infections. The Latin American Coalition for Escherichia coli Research (LACER) was created as a multidisciplinary network of international research groups working with E. coli with the ultimate goal of advancing understanding of E. coli, and to prepare the next generation of American E. coli investigators. As such, this book compiles the knowledge of these investigators about E. coli, a commensal bacteria living inside its host, and a pathogen causing disease in animals and humans. Escherichia coli in the Americas contains a series of 15 chapters written by experts, covering basic concepts regarding the different categories of E. coli, including their environmental niche, virulence mechanisms, host reservoir, and disease outcomes, as well as diagnosis, vaccine development and treatment. This book's target audience include trainees and students learning about the basic and clinical aspects of E. coli pathogenesis, as well as experts around the globe who wish to learn more about this pathogen and the public health impact this bacteria has in America.

Book excerpt: Foodborne illnesses continue to be a major public health concern. All members of a particular bacterial genera (e.g., Salmonella, Campylobacter) or species (e.g., Listeria monocytogenes, Cronobacter sakazakii) are often treated by public health and regulatory agencies as being equally pathogenic; however, this is not necessarily true and is an overly conservative approach to ensuring the safety of foods. Even within species, virulence factors vary to the point that some isolates may be highly virulent, whereas others may rarely, if ever, cause disease in humans. Hence, many food safety scientists have concluded that a more appropriate characterization of bacterial isolates for public health purposes could be by virotyping, i.e., typing food-associated bacteria on the basis of their virulence factors. The book is divided into two sections. Section I, “Foodborne Pathogens and Virulence Factors,” hones in on specific virulence factors of foodborne pathogens and the role they play in regulatory requirements, recalls, and foodborne illness. The oft-held paradigm that all pathogenic strains are equally virulent is untrue. Thus, we will examine variability in virulence between strains such as Listeria, Salmonella, Campylobacter, Cronobacter, etc. This section also examines known factors capable of inducing greater virulence in foodborne pathogens. Section II, “Foodborne Pathogens, Host Susceptibility, and Infectious Dose” , covers the ability of a pathogen to invade a human host based on numerous extraneous factors relative to the host and the environment. Some of these factors include host age, immune status, genetic makeup, infectious dose, food composition and probiotics. Readers of this book will come away with a better understanding of foodborne bacterial pathogen virulence factors and pathogenicity, and host factors that predict the severity of disease in humans.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes current advances in our understanding of how infectious disease represents an ecological interaction between a pathogenic microorganism and the host species in which that microbe causes illness. The contributing authors explain that pathogenic microorganisms often also have broader ecological connections, which can include a natural environmental presence; possible transmission by vehicles such as air, water, and food; and interactions with other host species, including vectors for which the microbe either may or may not be pathogenic. This field of science has been dubbed disease ecology, and the chapters that examine it have been grouped into three sections. The first section introduces both the role of biological community interactions and the impact of biodiversity on infectious disease. In turn, the second section considers those diseases directly affecting humans, with a focus on waterborne and foodborne illnesses, while also examining the critical aspect of microbial biofilms. Lastly, the third section presents the ecology of infectious diseases from the perspective of their impact on mammalian livestock and wildlife as well as on humans. Given its breadth of coverage, the volume offers a valuable resource for microbial ecologists and biomedical scientists alike.

Book excerpt: The title of the book "The Universe of Escherichia coli" aims to present and emphasize the huge diversity of this bacterial species and our efforts to prevent the E. coli infections. As it is part of the gut microbiota, E. coli is a well-known commensal species, and probiotic E. coli strains are successfully used for improving host's health. Also many "workhorse" E. coli strain exist that are employed in laboratory and biotechnology settings. But certain E. coli strains can cause intestinal and also extraintestinal infections at many anatomical sites. Therefore many efforts are undertaken to prevent E. coli infections, among them food safety, vaccines, but also new antimicrobial agents are searched for.

Book excerpt: Principles of Microbiological Troubleshooting in the Industrial Food Processing Environment provides proven approaches and suggestions for finding sources of microbiological contamination of industrially produced products. Industrial food safety professionals find themselves responsible for locating and eliminating the source(s) of food contamination. These are often complex situations for which they have not been adequately prepared. This book is written with them, the in-plant food safety/quality assurance professional, in mind. However, other professionals will also benefit including plant managers, regulatory field investigators, technical food safety policy makers, college instructors, and students of food science and microbiology. A survey of the personal and societal costs of microbial contamination of food is followed by a wide range of respected authors who describe selected bacterial pathogens, emerging pathogens, spoilage organisms and their significance to the industry and consumer. Dr. Kornacki then provides real life examples of in-plant risk areas / practices (depicted with photographs taken from a wide variety of food processing facilities). Factors influencing microbial growth, survival and death area also described. The reader will find herein a practical framework for troubleshooting and for assessing the potential for product contamination in their own facilities, as well as suggestions for conducting their own in-plant investigations. Selected tools for testing the environment and statistical approaches to testing ingredients and finished product are also described. The book provides suggestions for starting up after a processing line (or lines) have been shut down due to a contamination risk. The authors conclude with an overview of molecular subtyping and its value with regard to in-plant investigations. Numerous nationally recognized authors in the field have contributed to the book. The editor, Dr. Jeffery L. Kornacki, is President and Senior Technical Director of the consulting firm, Kornacki Microbiology Solutions in Madison, Wisconsin. He is also Adjunct Faculty with the Department of Food Science at the University of Georgia and also with the National Food Safety & Toxicology Center at Michigan State University.

Available in PDF, EPUB and Kindle. Book excerpt: This Brief will review the methods that are currently available for the detection, isolation, and typing of pathogenic E. coli with a particular focus on foodborne diseases caused by the Shiga toxigenic E. coli group, which have been implicated in a number of significant outbreaks in recent years. Pathogenic forms of E. coli can cause a variety of diarrheal diseases in hosts due to the presence of specific colonization and virulence factors, and pathogenicity-associated genes, which are generally not present in other E. coli. Six pathotypes of pathogenic E. coli are recognized (Shiga toxigenic E. coli, Enteropathogenic E. coli, Enterotoxigenic E. coli, Enteroinvasive E. coli, Enteroaggregative E. coli and Diffusely Adherent E. coli) and certain strains among these groups are major public health concerns due to the severity of disease that they can cause. Methods to detect and isolate these pathogens from a variety of sources are constantly evolving. In addition, the accumulation of knowledge on these pathogens allows for improved intervention strategies.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental Aspects of Zoonotic Diseases provides a definitive description, commentary and research needs of environmental aspects related to zoonotic diseases. There are many interrelated connections between the environment and zoonotic diseases such as: water, soil, air and agriculture. The book presents investigations of these connections, with specific reference to environmental processes such as: deforestation, floods, draughts, irrigation practices, soil transfer and their impact on bacterial, viral, fungal, and parasitological spread. Environmental aspects such as climate (tropical, sub-tropical, temperate, arid and semi-arid), developed and undeveloped countries, animal (domestic and wild) traffic animal border crossing, commercial animal trade, transportation, as well geography and weather on zoonosis, are also discussed and relevant scientific data is condensed and organized in order to give a better picture of interrelationship between the environment and current spread of zoonotic diseases. Altogether, the book presents a remarkable and a vast amount of potential future research directions based on the link: environment-vectors-pathogens-humans. The most up-to-date source of information on this increasingly important cross-disciplinary subject, Environmental Aspects of Zoonotic Diseases will be invaluable for environmentalists, veterinarians, medical staff, environmental engineers, government agencies and consultants working in this field.
