Download or read book Escherichia coli a Versatile Pathogen written by Gad Frankel and published by Springer. This book was released on 2018-11-02 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Escherichia coli is a facultative anaerobic Gamma-proteobacterium, which belongs to the family Enterobacteriaceae. While being an important constituent of the normal gut microbiota, specialized E. coli clones have acquired genetic elements that allow them to compete with the endogenous commensals, colonise normally sterile niches and cause disease. E. coli pathotypes can cause intestinal and extra intestinal infections (e.g. UTI, sepsis) and associate with mammalian cells while being extra- or intra-cellular. In recent years, E. coli infections have become a serious clinical problem, due to the rapid spread of antibiotic resistance. Thus, infections with intestinal E. coli (e.g. E. coli O104) or extraintestinal pathogenic strains (e.g. E. coli ST131) are becoming difficult to treat and are often lethal. Consequently, there is a pressing need to develop alternative control measures, including the identification of new drug targets and development of vaccines that offer lasting protection. This volume focuses on several types of E. coli infections (intestinal and extraintestinal), virulence factors, and E. coli pandemics. It addresses the problem of antibiotic resistance, and a dedicated chapter discusses the need to develop alternative control measures. Given its depth and breadth of coverage, the book will benefit all those interested in the biology, genetics, physiology and pathogenesis of E. coli, and in related vaccine development.

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.

Download or read book Escherichia coli written by Sujay Chattopadhyay and published by Elsevier Inc. Chapters. This book was released on 2013-06-12 with total page 43 pages. 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.
Download or read book Escherichia coli written by Amidou Samie and published by BoD – Books on Demand. This book was released on 2017-07-12 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Escherichia coli is a versatile organism and very diverse. Members of this species vary from very pathogenic agents causing different types of diseases including meningitis, gastroenteritis, and septicemia, just to cite a few, to harmless organisms living in the intestines of both humans and animals. E. coli has also been used as a model organism for most bacteria except a few. For this reason, its study provides a huge advantage and can help understand the mechanisms involved in different processes such as pathogenesis, environmental disinfection, nutrient utilization, antibiotic resistance, and diagnostic/detection methods, and these are indeed the topics discussed in this book. The book has been divided into four main sections representing the different facets of E. coli applications, which include disease, biotechnology, environmental engineering and innovative approaches to detection, and lastly its physiology and cell biology. Such processes can be applied to the study of other organisms as well considering the development of diversity; for example, many organisms are capable of horizontal gene transfer, which is capable of increasing the fitness of the bacterial organisms involved and has a great impact on the control of such bacterial organism.

Download or read book Pathogenic Escherichia Coli written by Pina M. Fratamico and published by . This book was released on 2018-04 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Escherichia coli is an important member of the normal healthy microbiome of humans and other mammals. In addition, some strains are thought to be probiotic, and therefore beneficial to the host. However, other strains of E. coli have evolved into highly versatile, and frequently deadly, pathogens, the resultant diseases causing significant economic loss and public health burdens worldwide. Recent studies have shown that the E. coli genome has a high plasticity allowing it to adapt to new niches and survive in stressful conditions and to evolve into new hybrid strains with shared genes, including virulence genes. Omics and whole genome sequencing approaches have transformed research in this field allowing fascinating new insights into the molecular and cellular biology of the bacterium thus paving the way for the development of novel therapeutic strategies. Under the expert guidance of the editors in this book, renowned international authors provide timely and up-to-date reviews of current cutting-edge E. coli omics, molecular- and cellular-biology research. Topics range from E. coli genome plasticity and evolution to the application of omics technologies for in silico modeling to understand stress-triggered physiological responses. This authoritative volume is essential reading for scientists, both experts and students, working on pathogenic E. coli in academia, government, and biotechnology companies. It is also a must-read for anyone with an interest in bacterial pathogenesis and an important acquisition for all microbiology libraries.
Download or read book Detection and Typing Strategies for Pathogenic Escherichia coli written by Lucia Rivas and published by Springer. This book was released on 2015-01-28 with total page 114 pages. 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.

Download or read book Size Limits of Very Small Microorganisms written by National Research Council and published by National Academies Press. This book was released on 1999-10-13 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: How small can a free-living organism be? On the surface, this question is straightforward-in principle, the smallest cells can be identified and measured. But understanding what factors determine this lower limit, and addressing the host of other questions that follow on from this knowledge, require a fundamental understanding of the chemistry and ecology of cellular life. The recent report of evidence for life in a martian meteorite and the prospect of searching for biological signatures in intelligently chosen samples from Mars and elsewhere bring a new immediacy to such questions. How do we recognize the morphological or chemical remnants of life in rocks deposited 4 billion years ago on another planet? Are the empirical limits on cell size identified by observation on Earth applicable to life wherever it may occur, or is minimum size a function of the particular chemistry of an individual planetary surface? These questions formed the focus of a workshop on the size limits of very small organisms, organized by the Steering .Group for the Workshop on Size Limits of Very Small Microorganisms and held on October 22 and 23, 1998. Eighteen invited panelists, representing fields ranging from cell biology and molecular genetics to paleontology and mineralogy, joined with an almost equal number of other participants in a wide-ranging exploration of minimum cell size and the challenge of interpreting micro- and nano-scale features of sedimentary rocks found on Earth or elsewhere in the solar system. This document contains the proceedings of that workshop. It includes position papers presented by the individual panelists, arranged by panel, along with a summary, for each of the four sessions, of extensive roundtable discussions that involved the panelists as well as other workshop participants.
