Book Description
Phagocytic cells and complement are probably the most important components of host defense against bacteria which, after overcoming the mucosal and epithelial barriers, multiply in the subepithelial tissue and may threaten to disseminate and invade the blood stream and different organs. Questions concerning the factors which regulate the interactions of the bacterial cell with host defenses are a challenge to research and lead to practical applications for the prevention, treatment and diagnosis of infectious diseases. The questions of expression and regulation of virulence related bacterial genes and gene products, the specific mechanisms of defence reactions by complement and phagocytic cells, their mutual interactions with bacteria and especially bacterial surfaces are focused. Considerations on how to translate this knowledge into the management of infectious diseases are also included.

Book Description
The complement system, first described more than a century ago, was for many years the ugly duckling of the immunology world, but no more. Complement in recent years has blossomed into a fascinating and fast moving field of immediate relevance to clinical scientists in fields as diverse as transplantation biology, virology, and inflammation. Despite its emergence from the shadows, complement retains an unwarranted reputation for being “difficult.” This impression derives in large part from the superficially complicated nomenclature, a relic of the long and tortuous process of unraveling the system, of naming components in order of discovery rather than in a syst- atic manner. Once the barrier of nomenclature has been surmounted, then the true simplicity of the system becomes apparent. Complement comprises an activation system and a cytolytic system. The former has diverged to focus on complement to distinct targets—bacteria, - mune complexes, and others—so that texts now describe three activation pa- ways, closely related to one another, but each with some unique features. The cytolytic pathway is the same regardless of the activation process and kills cells by creating pores in the membrane. Complement plays an important role in killing bacteria and is essential for the proper handling of immune complexes. Problems occur when complement is activated in an inappropriate manner—the potent inflammation-inducing products of the cascade then cause unwanted tissue damage and destruction.

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
All multicellular organisms may possess innate immunity mediated by defense mechanisms with which the organism is born. In recent years much has been learned about the diversity of innate immune mechanisms. A large array of naturally produced antimicrobial peptides has been de fined. A variety of cell surface receptors that recognize common patterns displayed by infectious organisms have been identified along with the intracellular pathways that these receptors use to activate cellular defense functions. Cell surface receptors on natural killer (NK) cells have been shown to sense microbial invasion in neighboring cells, thereby setting into motion their elimination by cy totoxic mechanisms. Other receptors have been found to facilitate phagocytosis and intracellular killing of microbes by phagocytic cells. These and other natural defense mechanisms have traditionally been viewed as the first line of body defense in vertebrate species that also possess the capacity for acquired or adaptive immunity. Sharks and all of the other jawed vertebrates generate large repertoires of T and B lymphocyte clones that display different antigen specific receptors in the form ofT cell receptors (TCR) and immunoglobulins (Ig) that allow them to recognize and respond to antigens in collaboration with antigen-present ing cells. Memory T and B cells are then generated to allow faster and heightened cellular and humoral immune re sponses on secondary antigen encounter. In recent years it has also become obvious that innate immune responses can directly influence adaptive immune responses in ways that will enhance body defense.

Book Description
Lactoferrin is an intriguing protein with an interesting structure and several known or suggested biological activities. We feel that attention on this protein has been too limited and diffuse, partly because it has been "hidden" among other well-known iron-binding proteins such as hemoglobin, ferritin and transferrin, but also perhaps because its biological functions are so diverse. Investigators that focus on lactoferrin represent a wide variety of medical and scientific disciplines that do not usually come together. It was our intention to improve that situation with this symposium. In this book, experts from a variety of disciplines describe the present knowledge of the structural features of lactoferrin, its carbohydrate side chains and its capacity to bind different metal ions and anions. Several of the possible physiological functions of lactoferrin are described in detail, including the role of lactoferrin in bacterial killing, its involvement in growth and proliferation, in immune function and in iron absorption. Aspects of the molecular biology of lactoferrin and its specific interactions with different cell types are also included. Finally, as lactoferrin now has become commercially available in larger quantities, possible industrial applications are discussed. The book should give the interested reader a thorough insight into our present knowledge of lactoferrin.

Book Description
Lyme disease (Lyme borreliosis) is the most prevalent vector-borne illness in the United States and Europe and a growing threat to global health. In addition Lyme disease is considered a model system of emerging infectious diseases. The book Borrelia: Molecular Biology, Host Interaction and Pathogenesis published in 2010 was the first state-of-the-art reference work covering the myriad, interlaced facets of the enzootic disorders caused by pathogenic Borrelia. This current volume, by the same editors, builds on the previous work and contains a vast amount of new information, a wider scope, and increased coverage of genomics, genetics, evolutionary biology, vector biology, physiology, pathogenicity, immune response, and immune evasion. Written by renowned scientists who have made seminal contributions to the field, this book contains an expansive treatment of the options to track live spirochetes and evaluate gene expression in ticks and mice, provides insights into the workings of the flagellar motor, presents up-to-date research on the modulation of gene expression, and reviews recent studies on the Lyme disease spirochete's networks of regulatory pathways. The volume highlights and describes in detail the tremendous advances in understanding of the Borrelia genus at the molecular and cellular levels as well as the pathogenesis of Lyme disease and relapsing fever. This comprehensive volume is indispensable for anyone involved in Borrelia and Lyme disease research and is highly recommended for microbiologists, immunologists, and physicians with an interest in spirochetes, vector-borne illness, or emerging infectious diseases. The book is a recommended reference volume for all microbiology libraries.
