Download or read book Phagocytosis of Bacteria and Bacterial Pathogenicity written by Joel D. Ernst and published by Cambridge University Press. This book was released on 2006-09-07 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides up-to-date information on the crucial interaction of pathogenic bacteria and professional phagocytes, the host cells whose purpose is to ingest, kill, and digest bacteria in defense against infection. The introductory chapters focus on the receptors used by professional phagocytes to recognize and phagocytose bacteria, and the signal transduction events that are essential for phagocytosis of bacteria. Subsequent chapters discuss specific bacterial pathogens and the strategies they use in confronting professional phagocytes. Examples include Helicobacter pylori, Streptococcus pneumoniae, and Yersinae, each of which uses distinct mechanisms to avoid being phagocytosed and killed. Contrasting examples include Listeria monocytogenes and Mycobacterium tuberculosis, which survive and replicate intracellularly, and actually cooperate with phagocytes to promote their entry into these cells. Together, the contributions in this book provide an outstanding review of current knowledge regarding the mechanisms of phagocytosis and how specific pathogenic bacteria avoid or exploit these mechanisms.

Download or read book The Pathogenesis of Bacterial Infections written by George G. Jackson and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: G. G. Jackson The pathogenesis of bacterial infection defines the dynamics at an interface of ecologic association of bacteria and host. First, it occurs at the portal of initial contact with a per missive target cell. The infected cell provides either a passive or a specific receptor for the bacterium or its products, to gether with ligands and an environment of helper and inhibiting factors. The result is bacterial replication to produce an im balance of a potentially commensal relation which, under other defined conditions, would be optimal for the survival of both the host and bacterial cells. Virulence and pathogenesis are both absolute and relative terms. They must be interpreted strictly according to the circumstances of site-specific inter actions of bacterial and host cells, membrane composition, structure, characteristics, and environmental substances. The bacteria themselves may have, acquire, or switch on or off under certain conditions, the products or properties that produce cellular damage that we recognize as virulence. Another result of bacterial infection may be to stimulate a normal host cell function to perform at a pathophysiologic level, causing illness that we recognize as virulence. A third marker of virulence may be the ability to invade a cell or tissue barrier and produce a pathologic effect at a site that is remote from the portal of commensal association or pathologic entry.
Download or read book Bacterial Invasion of Host Cells written by Richard J. Lamont and published by Cambridge University Press. This book was released on 2004-03-29 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concerns the intimate association between bacteria and host cells. Many bacterial pathogens are able to invade and survive within cells at mucosal membranes. Remarkably, the bacteria themselves orchestrate this process through the exploitation of host cellular signal transduction pathways. Intracellular invasion can lead to disruption of host tissue integrity and perturbation of the immune system. An understanding of the molecular basis of bacterial invasion and of host cell adaptation to intracellular bacteria will provide fundamental insights into the pathophysiology of bacteria and the cell biology of the host. The book details specific examples of bacteria that are masters of manipulation of eukaryotic cell signaling and relates these events to the broader context of host-pathogen interaction. Written by experts in the field, this book will be of interest to researchers and graduate students in microbiology, immunology, biochemistry, as well as molecular medicine and dentistry.

Download or read book Bacterial Pathogens and Their Virulence Factors written by Douglas I. Johnson and published by Springer. This book was released on 2017-11-23 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacterial Pathogens and their Virulence Factors contains a detailed description of 32 major bacterial pathogens that affect human health and their associated virulence determinants. Chapter 1 gives an overview of the different types and classes of general virulence factors involved in host cell adherence and invasion, dissemination within the host, host cell damage, and evasion of host defense systems, as well as mechanisms by which these virulence factors are regulated. Chapters 2 through 33 give concise descriptions of the disease states associated with the 32 bacterial genera and their major pathogenic species, along with an in-depth description of the individual virulence factors that have been found to be functionally involved in pathogenicity. A detailed bibliography derived from primary literature and review articles accompanies each of these chapters, allowing the reader to delve more deeply into individual pathogens and their virulence determinants. Chapter 34 discusses the exciting possibilities and initial successes of using detailed information on a pathogen’s virulence toolkit to design new therapeutics aimed at specific virulence traits.
Download or read book Bacterial Exotoxins How Bacteria Fight the Immune System written by Inka Sastalla and published by Frontiers Media SA. This book was released on 2016-10-07 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacterial pathogenicity factors are functionally diverse. They may facilitate the adhesion and colonization of bacteria, influence the host immune response, assist spreading of the bacterium by e.g. evading recognition by immune cells, or allow bacteria to dwell within protected niches inside the eukaryotic cell. Exotoxins can be single polypeptides or heteromeric protein complexes that act on different parts of the cells. At the cell surface, they may insert into the membrane to cause damage; bind to receptors to initiate their uptake; or facilitate the interaction with other cell types. For example, bacterial superantigens specifically bind to major histocompatibility complex (MHC) II molecules on the surface of antigen presenting cells and the T cell receptor, while cytolysins cause pore formation. For intracellular activity, exotoxins need to be translocated across the eukaryotic membrane. Gram-negative bacteria can directly inject effector proteins in a receptor-independent manner by use of specialized needle apparatus such as bacterial type II, III, or type IV secretion systems. Other methods of translocation include the phagocytic uptake of bacteria followed by toxin secretion, or receptor-mediated endocytosis which allows the targeting of distinct cell types. Receptor-based uptake is initiated by the binding of heteromeric toxin complexes to the cell surface and completed by the translocation of the effector protein(s) across the endosomal membrane. In the cytosol, toxins interact with specific eukaryotic target proteins to cause post-translational modifications that often result in the manipulation of cellular signalling cascades and inflammatory responses. It has become evident that the actions of some bacterial toxins may exceed their originally assumed cytotoxic function. For example, pore-forming toxins do not only cause cytolysis, but may also induce autophagy, pyroptosis, or activation of the MAPK pathways, resulting in adjustment of the host immune response to infection and modification of inflammatory responses both locally and systemically. Other recently elucidated examples of the immunomodulatory function of cell death-inducing exotoxins include TcdB of Clostridium difficile which activates the inflammasome through modification of cellular Rho GTPases, or the Staphyloccocus d-toxin which activates mast cells. The goal of this research topic was to gather current knowledge on the interaction of bacterial exotoxins and effector proteins with the host immune system. The following 16 research and review articles in this special issue describe mechanisms of immune modification and evasion and provide an overview over the complexity of bacterial toxin interaction with different cells of the immune system.

Available in PDF, EPUB and Kindle. Book excerpt: Although the vast majority of bacteria are harmless or beneficial, quite a few bacteria are pathogenic. Pathogenic bacteria are only pathogenic under certain conditions, such as a wound that allows for entry into the blood, or a decrease in immune function. In this book, the authors present current research in the study of the virulence mechanisms, diagnosis and management of bacterial pathogens. Topics discussed include Pseudomonas aeruginosa (P aeruginosa) in our environment; phage therapy in the treatment of bacterial infections; P mirabilis virulence factor associated with urinary tract infections; efflux pumps for the multi-drug resistant phenotypes of bacterial pathogens; and the role of HtrA as a chaperone and protease in bacterial pathogenesis.
Download or read book Emerging Bacterial Pathogens written by Inge Mühldorfer and published by Karger Medical and Scientific Publishers. This book was released on 2001-01-01 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest public health achievements during the last century was the reduction of infectious diseases due to public sanitation measures, vaccines and antibiotics. However, in recent years, several new infectious diseases have been identified, and since the appearance of the first penicillin-resistant bacteria, 'old diseases' have reemerged. Volume 8 of Contributions to Microbiology provides an overview of a great variety of bacterial pathogens representative of those groups and discusses the underlying reasons for disease emergence. The various chapters clearly illustrate how changes in society, technology and the environment result in the appearance or spread of bacterial pathogens. Not only bacterial human pathogens, but also bacterial plant pathogens are an issue and serve as an example of how bacteria can adapt very specifically to a particular host environment. As a consequence of this adaptability, the available antimicrobial drugs have become less effective against many infectious agents; the reasons for this are thoroughly discussed in the book. There is an urgent need for the development of new antibiotics. The volume therefore concludes with a chapter on modern approaches which allow a rational design of a new generation of antimicrobial drugs less likely to become ineffective or cause broad-spectrum drug resistance.
