Book Description
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.

Book Description
Welcome to the wonderful world of microbiology! Yay! So. What is microbiology? If we break the word down it translates to "the study of small life," where the small life refers to microorganisms or microbes. But who are the microbes? And how small are they? Generally microbes can be divided in to two categories: the cellular microbes (or organisms) and the acellular microbes (or agents). In the cellular camp we have the bacteria, the archaea, the fungi, and the protists (a bit of a grab bag composed of algae, protozoa, slime molds, and water molds). Cellular microbes can be either unicellular, where one cell is the entire organism, or multicellular, where hundreds, thousands or even billions of cells can make up the entire organism. In the acellular camp we have the viruses and other infectious agents, such as prions and viroids. In this textbook the focus will be on the bacteria and archaea (traditionally known as the "prokaryotes,") and the viruses and other acellular agents.

Book Description
A comprehensive compendium of scholarly contributions relating to bacterial virulence gene regulation. • Provides insights into global control and the switch between distinct infectious states (e.g., acute vs. chronic). • Considers key issues about the mechanisms of gene regulation relating to: surface factors, exported toxins and export mechanisms. • Reflects on how the regulation of intracellular lifestyles and the response to stress can ultimately have an impact on the outcome of an infection. • Highlights and examines some emerging regulatory mechanisms of special significance. • Serves as an ideal compendium of valuable topics for students, researchers and faculty with interests in how the mechanisms of gene regulation ultimately affect the outcome of an array of bacterial infectious diseases.

Book Description
Many bacteria, such as certain Neisseria and Haemophilus or Escherichia coli, are able to withstand the bactericidal activity of complement and phagocytes. This bacterial self protection is brought about by encapsulation. Bacterial capsules thus enable the pathogenic bacteria to survive in the host by counter action or evasion of the nonspecific host defense in the early pre immune phase of an infection. It is only in the late immune phase of the infection, when specific anticapsular antibodies are formed and enforce the host's defense system, that this protective action is overcome. Encapsulated bacteria are then killed and eliminated. Interestingly, some capsules can not or only inefficiently be handled by the immune system. The ensuing lack of antibody formation results in a prolonged susceptibility of the host to the pathogenic bacteria exhibiting such capsules. It was found that bacterial capsules consist of acidic poly saccharides. From this it followed that the role of the capsules in the interaction of encapsulated bacteria with the host may be due to the chemistry of the capsular polysaccharides. This led to intensive studies of capsular polysaccharides in many laboratories. Our increasing knowledge of the structural features of capsular polysaccharides prompted not only immuno chemical studies analyzing the interactions of these poly saccharide antigens and characterizing the epitopes, but also investigations into their biosynthesis. These studies were complemented and supported by genetic analyses. Today many interdisciplinary investigations of capsular polysaccharides are in progress.

Book Description
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.

Book Description
Molecular Basis of Bacterial Pathogenesis focuses on the molecular mechanism of disease associated with bacterial pathogens. Topics covered include the population genetics of bacterial pathogenesis; environmental modulation of gene expression in gram-negative pathogens; and bacterial invasion and intracellular growth. Bacterial toxins are also discussed. This volume is comprised of 20 chapters and begins with an overview of pathogenesis, paying particular attention to common elements and genetic mechanisms of regulation. The discovery that many bacterial pathogens are clonal, with individual clones often having a greater virulence than others, is then considered. The next section deals with the regulation of synthesis of surface components and their role in colonization of the host and/or evasion of the host immune defense systems; antigenic variation and its role in evasion of the host immune response; and the role of iron acquisition systems in the colonization of the host. Subsequent chapters explore the invasion and intracellular growth of facultative and obligate intracellular parasites. The last section is devoted to studies on the role of bacterial toxic products in pathogenesis. Bacterial lipopolysaccharides (endotoxins) and exotoxins are described. This book should be of interest to molecular biologists, physiologists, clinical specialists, pathologists, and geneticists.
