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.

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.

This book was released on 2016-07-01 with total page 1464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteria in various habitats are subject to continuously changing environmental conditions, such as nutrient deprivation, heat and cold stress, UV radiation, oxidative stress, dessication, acid stress, nitrosative stress, cell envelope stress, heavy metal exposure, osmotic stress, and others. In order to survive, they have to respond to these conditions by adapting their physiology through sometimes drastic changes in gene expression. In addition they may adapt by changing their morphology, forming biofilms, fruiting bodies or spores, filaments, Viable But Not Culturable (VBNC) cells or moving away from stress compounds via chemotaxis. Changes in gene expression constitute the main component of the bacterial response to stress and environmental changes, and involve a myriad of different mechanisms, including (alternative) sigma factors, bi- or tri-component regulatory systems, small non-coding RNA’s, chaperones, CHRIS-Cas systems, DNA repair, toxin-antitoxin systems, the stringent response, efflux pumps, alarmones, and modulation of the cell envelope or membranes, to name a few. Many regulatory elements are conserved in different bacteria; however there are endless variations on the theme and novel elements of gene regulation in bacteria inhabiting particular environments are constantly being discovered. Especially in (pathogenic) bacteria colonizing the human body a plethora of bacterial responses to innate stresses such as pH, reactive nitrogen and oxygen species and antibiotic stress are being described. An attempt is made to not only cover model systems but give a broad overview of the stress-responsive regulatory systems in a variety of bacteria, including medically important bacteria, where elucidation of certain aspects of these systems could lead to treatment strategies of the pathogens. Many of the regulatory systems being uncovered are specific, but there is also considerable “cross-talk” between different circuits. Stress and Environmental Regulation of Gene Expression and Adaptation in Bacteria is a comprehensive two-volume work bringing together both review and original research articles on key topics in stress and environmental control of gene expression in bacteria. Volume One contains key overview chapters, as well as content on one/two/three component regulatory systems and stress responses, sigma factors and stress responses, small non-coding RNAs and stress responses, toxin-antitoxin systems and stress responses, stringent response to stress, responses to UV irradiation, SOS and double stranded systems repair systems and stress, adaptation to both oxidative and osmotic stress, and desiccation tolerance and drought stress. Volume Two covers heat shock responses, chaperonins and stress, cold shock responses, adaptation to acid stress, nitrosative stress, and envelope stress, as well as iron homeostasis, metal resistance, quorum sensing, chemotaxis and biofilm formation, and viable but not culturable (VBNC) cells. Covering the full breadth of current stress and environmental control of gene expression studies and expanding it towards future advances in the field, these two volumes are a one-stop reference for (non) medical molecular geneticists interested in gene regulation under stress.

Available in PDF, EPUB and Kindle. Book excerpt: The Latin American region has been at the forefront in combating infections caused by Escherichia coli strains in humans, animals, and the environment. The continuous emergence and evolution of pathogenic E. coli strains associated with human and animal infections have demonstrated that (i) groups of related pathogenic E. coli are responsible for most infections caused by this bacterial species; (ii) diverse virulence phenotypes expressed during infection defined each one of these pathogroups; (iii) the geographical distribution of pathogroups in Latin America and the evolution of new isolates was defined by the dominant pathogroup and presence of distinct virulence strains; (iv) acquisition of mobile elements or accumulation of point mutations accelerate the development of antibiotic resistance in some of these strains. The Latin American Coalition for Escherichia coli Research (LACER), a multidisciplinary network of over seventy research groups in eleven Latin American countries and the USA, was established in 2009 to apply One Health principles in defining and combating this pathogen. The previous edition of this text, Escherichia coli in the Americas (c. 2016) was the culmination of their wisdom about E. coli, from its role as a commensal bacterium to its characteristics as a pathogen causing disease in animals and humans. This new edition presents recent advances and contextualizes all aspects of E. coli in a One Health perspective, from the environment, to animals, to humans. It addresses E. coli interactions with host microbiota, CNS, and phages. It includes cutting edge insights on hybrid strains, molecular mechanisms of virulence and pathogenesis, resistance, domestic and wild reservoirs, disease surveillance in Latin America, genomic analysis, food safety, and new therapies. Crucially, it also provides translations and analysis of key reports on Escherichia coli published in Spanish and Portuguese. This book serves as a critical resource for scientists in industry and academia, clinicians managing associated infections, and trainees and students studying basic and clinical aspects of E. coli pathogenesis.

This book was released on 2015-07-02 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the most prevalent and devastating human and animal pathogens have part of their lifecycle out-with the animal host. These pathogens have a remarkably wide capacity to adapt to a range of quite different environments: physical, chemical and biological, which is part of the key to their success. Many of the well-known pathogens that are able to jump between hosts in different biological kingdoms are transmitted through the faecal-oral and direct transmission pathways, and as such have become important food-borne pathogens. Some high-profile examples include fresh produce-associated outbreaks of Escherichia coli O157:H7 and Salmonella enterica. Other pathogens may be transmitted via direct contact or aerosols are include important zoonotic pathogens. It is possible to make a broad division between those pathogens that are passively transmitted via vectors and need the animal host for replication (e.g. virus and parasites), and those that are able to actively interact with alternative hosts, where they can proliferate (e.g. the enteric bacteria). This research topic will focus on plants as alternative hosts for human pathogens, and the role of plants in their transmission back to humans. The area is particularly exciting because it opens up new aspects to the biology of some microbes already considered to be very well characterised. One aspect of cross-kingdom host colonisation is in the comparison between the hosts and how the microbes are able to use both common and specific adaptations for each situation. The area is still in relative infancy and there are far more questions than answers at present. We aim to address important questions underlying the interactions for both the microbe and plant host in this research topic.

Book excerpt: The study of the pathogenesis of Shiga toxin-producing Escherichia coli (STEC) infections encompasses many different disciplines, including clinical microbiology, diagnostics, animal ecology, and food safety, as well as the cellular microbiology of both bacterial pathogenesis and the mechanisms of toxin action. E. coli: Shiga Toxin Methods and Protocols aims to bring together a number of experts from each of these varied fields in order to o- line some of the basic protocols for the diagnosis and study of STEC pat- genesis. We hope that our book will prove a valuable resource for the clinical microbiologist as well as the cellular microbiologist. For the clinical microbiologist, our aim is to detail a number of current protocols for the detection of STEC in patient samples, each of which have their own advantages. Chapter 1 provides an introduction into the medical significance of STEC infections. Chapters 2–7 follow with protocols for the diagnosis and detection of STEC bacteria in patient and animal samples.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Molecular typing of foodborne pathogens has become an indispensable tool in epidemiological studies. Thanks to these techniques, we now have a better understanding of the distribution and appearance of bacterial foodborne diseases and have a deeper knowledge of the type of food products associated with the major foodborne pathogens. Within the molecular techniques, DNA-based techniques have prospered for more than 40 years and have been incorporated in the first surveillance systems to monitor bacterial foodborne pathogens in the United States and other countries. However, DNA techniques vary widely and many microbiology laboratory personnel working with food and/or water face the dilemma of which method to incorporate. DNA Methods in Food Safety: Molecular Typing of Foodborne and Waterborne Bacterial Pathogens succinctly reviews more than 25 years of data on a variety of DNA typing techniques, summarizing the different mathematical models for analysis and interpretation of results, and detailing their efficacy in typing different foodborne and waterborne bacterial pathogens, such as Campylobacter, Clostridium perfringens, Listeria, Salmonella, among others. Section I describes the different DNA techniques used in the typing of bacterial foodborne pathogens, whilst Section II deals with the application of these techniques to type the most important bacterial foodborne pathogens. In Section II the emphasis is placed on the pathogen, and each chapter describes some of the most appropriate techniques for typing each bacterial pathogen. The techniques presented in this book are the most significant in the study of the molecular epidemiology of bacterial foodborne pathogens to date. It therefore provides a unique reference for students and professionals in the field of microbiology, food and water safety and epidemiology and molecular epidemiology.

This book was released on 2014-11-11 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shiga toxin-producing Escherichia coli (STEC) is an important foodborne pathogen associated with both outbreaks and sporadic cases of human disease, ranging from uncomplicated diarrhoea to haemorrhagic colitis (HC) and haemolytic uraemic syndrome (HUS). STEC affects children, elderly and immuno-compromised patients. STEC is capable of producing Shiga toxin type 1 (Stx1), type 2 (Stx2) or both, encoded by stx1 and stx2 genes, respectively. These strains are likely to produce putative accessory virulence factors such as intimin (encoded by eae), an enterohaemolysin (EhxA) and an autoagglutinating protein commonly associated with eae-negative strains (Saa), both encoded by an enterohaemorrhagic plasmid. Several studies have confirmed that cattle are the principal reservoir of STEC (O157 and non-O157:H7 serotypes) and many of these serotypes have been involved in HUS and HC outbreaks in other countries. Transmission of STEC to humans occurs through the consumption of undercooked meat, vegetables and water contaminated by faeces of carriers and by person-to-person contact. Diagnostic methods have evolved to avoid selective diagnostics, currently using molecular techniques for typing and subtyping of strains. Control is still a challenge, although there are animal vaccines directed against the serotype O157:H7.
