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.

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.

This book primarily covers the general description of foodborne pathogens and their mechanisms of pathogenesis, control and prevention, and detection strategies, with easy-to-comprehend illustrations. The book is an essential resource for food microbiology graduate or undergraduate students, microbiology professionals, and academicians involved in food microbiology, food safety, and food defense-related research or teaching. This new edition covers the significant progress that has been made since 2008 in understanding the pathogenic mechanism of some common foodborne pathogens, and the host-pathogen interaction. Foodborne and food-associated zoonotic pathogens, responsible for high rates of mortality and morbidity, are discussed in detail. Chapters on foodborne viruses, parasites, molds and mycotoxins, and fish and shellfish are expanded. Additionally, chapters on opportunistic and emerging foodborne pathogens including Nipah virus, Ebola virus, Aeromonas hydrophila, Brucella abortus, Clostridium difficile, Cronobacter sakazakii, and Plesiomonas shigelloides have been added. The second edition contains more line drawings, color photographs, and hand-drawn illustrations.

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.

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.

Natural additives are increasingly favoured over synthetic ones as methods of ensuring food safety and long shelf-life. The antimicrobial properties of both plant-based antimicrobials such as essential oils and proteins such as bacteriocins are used in, for example, edible preservative films, in food packaging and in combination with synthetic preservatives for maximum efficacy. New developments in delivery technology such as nanoencapsulation also increase the potential of natural antimicrobials for widespread use in industry. Part one introduces the different types of natural antimicrobials for food applications. Part two covers methods of application, and part three looks at determining the effectiveness of natural antimicrobials in food. Part four focuses on enhancing quality and safety, and includes chapters on specific food products. Reviews different types of antimicrobials used in food safety and quality Covers how antimicrobials are created to be used in different foods Examines how the antimicrobials are used in foods to enhance the safety and quality
