Bacterial Capsules by Klaus Jann,Barbara Jann Pdf

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.

The Complex World of Polysaccharides by Desiree Nedra Karunaratne Pdf

The complex world of polysaccharides is a compilation of the characteristics of a variety of polysaccharides from plants, animals and microorganisms. The diversity of these polysaccharides arises from the structural variations and the monosaccharide content which is under genetic control. The chemical and physical properties have made them useful in many pharmaceutical, food and industrial applications. These properties of the polysaccharides determine their biological activity and their function in various applications. The role played by polysaccharides in preservation and protection of food, as carriers of nutrients and drugs, their ability to interact with molecules both for efficient delivery as well as improving textures of food colloids and their use as therapeutics are some of the functions discussed.

The Bacterial Cell Wall by Guntram Seltmann,Otto Holst Pdf

The bacterial cell wall represents a very complex structure disconnecting the interior of single-cell organisms from the environment, thus protecting, but also enabling, them to interact with the surrounding milieu and to exchange both substances and information. Knowledge of the biochemistry of the cell wall (components) and the genetic background helps to understand their significance with regard to microbiology and immunology of bacteria. This book represents the second edition of a publication which was presented nearly 20 years ago in the German language (Die bakterielle Zellwand). Since that time our knowledge in this field has been significantly enlarged. Therefore, the manuscript had to be completely revised and updated. To maintain both the size and the introductory character of the book at least to a great extent, the authors had to restrict the presented material to that which appears basic and most important. This requirement must inevitably bring about many subjective factors. As pointed out in the first edition, the term cell wall was not taken too strictly. Since the constituents located outside the cytoplasmic membrane are frequently difficult to divide in structure, localisation, and/or function into true cell wall components and supplementary substances, they are all at least briefly mentioned.

Antimicrobial Chemotherapy by Roger Finch,Peter Davey,Mark H. Wilcox,William Irving Pdf

Antimicrobial agents are essential for the treatment of life-threatening infections and for managing the burden of minor infections in the community. In addition, they play a key role in organ and bone marrow transplantation, cancer chemotherapy, artificial joint and heart valve surgery. Unlike other classes of medicines, they are vulnerable to resistance from mutations in target microorganisms, and their adverse effects may extend to other patients (increased risk of cross-infection). As a consequence, there is a constant requirement for new agents, as well as practices that ensure the continued effective prescribing of licensed agents. Public awareness and concerns about drug resistant organisms has led to widespread publicity and political action in the UK, Europe and worldwide. The control of drug resistance and the implementation of good prescribing practice are now legal requirements in the UK as a result of the UK Health Act (2008). These fundamental changes underscore the need for a thorough understanding of the advantages and risks associated with specific antibiotic choices. This sixth edition of Antimicrobial Chemotherapy continues to be a valuable resource for undergraduates and graduates requiring a thorough grounding in the scientific basis and clinical application of these drugs. This new edition is updated to include the most recently licensed agents, notably in the treatment of viral infections including HIV/AIDS, and contains new guidance on prescribing practice and infection control practices that limit the development and spread of resistant organisms.

Antimicrobial Therapy in Abdominal Surgery by Haragopal Thadepalli,Askis K. Mandal Pdf

Over the past 50 years, important developments have taken place in surgical and antimicrobial aspects of the management of intestinal surgery and intra-abdominal sepsis. Many new pathogens like Clostridium difficile, Helibacter and Ruminococcus have been described, and many new beta-lactam drugs and quinolones have been introduced. Immunological aspects such as T cell factors and interleukins have been shown to play an important role in the pathogenesis of intra-abdominal sepsis. Important new pieces of surgical hardware, sutures, and surgical glues to salvage solid organs were added to the surgical armanentorium. This new book looks at all of these important developments and more. Over 900 articles were reviewed to synthesize the core information for this book. The editors' years of experience in trauma surgery and intra-abdominal sepsis add to the tremendous amount of information found in this book written for physicians, house-staff, and medical students.
