"Clostridium difficile" has been recognized as the cause of a broad spectrum of enteric disease ranging from mild antibiotic-associated diarrhea to pseudomembranous colitis. This volume gives new insights into the microbiology, diagnostics and epidemiology of "Clostridium difficile" and describes recent strategies in treatment of diseases caused by this agent. Main parts of the volume are devoted to "Clostridium difficile" toxins A and B which are the major virulence factors. The molecular biology, biochemistry, pharmacology and cell biology of these toxins which are the prototypes of a new family of large clostridial cytotoxins is described in great detail. "Clostridium difficile" toxins act as glucosyltransferases to inactivate small GTP-binding proteins of the Rho family which are involved in regulation of the actin cytoskeleton, cell adhesion and various signaling processes.

In May 1993, a cluster of cases of a lethal disease among healthy young people brought the attention of the world to the southwestern deserts. A previously unknown disease was killing up to 80% of the people it infected.
The reaction in the area and across the nation mixed fear, lack of information, and the struggles of doctors to save the victims of an unknown killer with hard science and the age old rhythmns of the desert. What came out was the story of a virus that had been killing since man arrived in the American continents, Hantavirus, with deadly relatives across the Americas and across the world. This book explains why and how the virus kills, and why it is still killing today. Why all of the science aimed at a virus identified back in 1993 has not brought a vaccine or a cure is part of the story, as is how that killer virus fits into the story of "new" diseases across the world.
The story of hantavirus disease, what has happened since that first outbreak, and what the real risks are is laid out by an experienced scientist and an award winning journalist living and working in the area of the 1993 outbreak.
Key Features
* Covers the full story of the recent hantavirus outbreak
* Includes interviews with survivors, and local reaction
* Presents the science in lay terms
* Places the event in the broader context of emerging diseases worldwide
* The only account which takes the reader beyond the initial outbreak in 1993-1994, bringing them up to late 1998

Mammalian reovirus had been the major focus for molecular understanding of the Reoviridae and has served as a model system for the other members of the family. Indeed, most of our initial understanding of molecular biology and processes involved in virus replication and pathogenesis for the members of the family was generated from reovirus studies. With this platform two other members of the family causing disease in human and/or animals have gained in prominence and the molecular interactions from a structural level through to host-virus interactions as well as the function of the structural and non-structural proteins in the virus life cycle has been investigated in detail.

This book reviews our current understanding of Reoviridae entry, disassembly/assembly and egress in addition to updating high resolution structures of virus proteins and capsids from three different genera of the family.

Microbial cell wall structures play a significant role in maintaining cells' shape, as protecting layers against harmful agents, in cell adhesion and in positive and negative biological activities with host cells. All prokaryotes, whether they are bacteria or archaea, rely on their surface polymers for these multiple functions. Their surfaces serve as the indispensable primary interfaces between the cell and its surroundings, often mediating or catalyzing important interactions.

"Prokaryotic Cell Wall Compounds" summarizes the current state of knowledge on the prokaryotic cell wall. Topics concerning bacterial and archaeal polymeric cell wall structures, biological activities, growth and inhibition, cell wall interactions and the applications of cell wall components, especially in the field of nanobiotechnology, are presented.

This book describes antibiotic resistance amongst pathogenic bacteria. It starts with an overview of the erosion of the efficacy of antibiotics by resistance and the decrease in the rate of replacement of redundant compounds. The origins of antibiotic resistance are then described. It is proposed that there is a large bacterial resistome which is a collection of all resistance genes and their precursors in both pathogenic and non-pathogenic bacteria. Ongoing resistance surveillance programs are also discussed, together with the perspective of a clinical microbiologist. The book then turns to specific themes such as the most serious area of resistance in pathogens, namely in Gram-negative organisms. The role of combinations of antibiotics in combating resistance emergence is discussed, particularly in the tuberculosis field, and then the importance of non-multiplying and persistent bacteria which are phenotypically resistant to antibiotics and prolong the duration of therapy of antibiotics which leads to poor compliance and resistance emergence. The role of anti-microbial compounds in textiles is covered, with its potential to exacerbate the spread of resistance. Then, efflux pumps are discussed. The final chapter describes the compounds which are in late stage clinical development, illustrating the paucity of the antibiotic pipeline, especially for Gram-negative bacteria.

There is a widespread consensus that use of antioxidants as a therapeutic approach may counteract free radical mediated pathologies. However, the role of antioxidants in normal physiology and redox signaling is still in its infancy. Since oxidative stress is related to various diseases and pathologies, scientists are eager to study the disease in humans, but it is not always ethical to study all the aspects of the disease in humans. Thus, it becomes mandatory to study the disease process and the mechanisms behind it through experimental models which generally involve animals, in vitro/cell culture studies, primates and even humans to a certain extent. Studies on Experimental Models contains data on the experimental models or review of such models of oxidative stress in various diseases. It is structured into six sections, which are as follows: diabetes, cardiovascular, neurology, ocular diseases, toxicology/environmental and in vitro/tissue culture. Each section presents a sketch of models in humans, animals and in vitro methods. Taken together, they comprise a valuable reference for basic and clinical scientists, one aimed at contributing to the advancement of oxidative stress research using appropriate animal models.

Alessandro Condivilla of Bologna first attempted a resection of the head of the pan creas in 1898, but several decades of further trial-and-error attempts ensued before the prototype procedure of pancreatoduodenectomy (PD) was established by Whipple in 1935. In the half-century following that landmark, refinements of surgical technique, including pancreatico-and bilio-entero anastomosis as well as develop ment of new technology to support perioperative management and patient care have contributed to the decrease in mortality and morbidity rates for obstructive jaundice and pancreatic fistula. The improvement in mortality and morbidity rates associated with PD has led to an increase in the number of patients undergoing the procedure and in the number of institutions performing it. Indications for PD have also been expanded. In the early years after PD was established as a viable procedure, periampullary carcinoma was the most common indication; now PD is indicated for a number of benign and malignant diseases. Some surgeons believe that PD is the procedure of choice for certain types of chronic pancreatitis, pancreatico-biliary maljunction, and pancreatic and duodenal trauma. Other surgeons have reported the necessity of PD for lymph node dissection of gallbladder carcinoma. Consequently, the basic procedure has been greatly modi fied to accommodate the specific conditions of each disease. For patients with malig nancy, extended procedures have been developed to improve the curative resection rate and ensure complete lymph node dissection.

It has been estimated that there are more microbial cells inhabiting the human body than there are eukaryotic cells of which it is made up. This normal microflora usually co-exists relatively peacefully with the host and does not cause infection. The mechanisms by which this co-existence is achieved are still not properly understood and the interaction between the normal microflora and the host is far from simple. For a variety of reasons, however, this interaction can be disturbed and often results in the microflora becoming pathogens. The study of the diseases then caused is important both in terms of treatment and in terms of contributing to our understanding of the mechanisms by which the normal microflora usually interacts with the host. This title brings together an international list of contributors, all of whom have active research interests in the normal microflora. Each of the chapters reviews current knowledge about a specific group or organism within the microflora and the diseases they can cause. Microflora of the skin, respiratory tract, oral cavity, gastrointestinal system and genital tract are all discussed and the impact of molecular methods on our understanding of the normal microflora is emphasised throughout the book. Medical microbiologists, dental specialists, infectious disease specialists, nutritionists and gastroenterologists will all find this book of immense interest and value, as will epidemiologists, dermatologists and general microbiologists.

Although virology and immunology are now considered separate disciplines, history shows that these areas ofinvestigation always overlapped and one cannot really exist without the other. This trend has become particularly significant and fruitful in the past few years in the area of herpesvirus research. The genomes of the most important herpesviruses have been sequenced, a significant portion of their genes have been identified, and many secrets of regulation of gene expr- sion have been unraveled. Now this progress sets the stage for a true revolution in herpesvirus research: analysis of interactions between the host and the virus. Because herpesviruses can induce, suppress, and fool the immune system, the most productive herpesvirologists are also expert immunologists, and the current results ofthis interdisciplinary effort are truly remarkable. Because herpesviruses cause many important human diseases, the devel- ment of vaccines against these agents is a very significant goal. This effort is also very challenging because of the complexity of herpesviruses and the lack of sufficient information about immune responses. The remarkable ability of herpesviruses to escape immune responses is - other feature that brings immunology and virology together. Herpesviruses - code many proteins that interact with and down-regulate some key elements of the immune system. Thisproperty of herpesviruses represents amajor challenge in developing strategies against these viruses. On the positive side, these viral proteins also provide novel tools for analyzing specific immune reactions and molecular mechanisms.

This book covers lymphoproliferative disorders in patients with congenital or acquired immunodeficiencies. Acquired immunodeficiencies are caused by infections with the human immunodeficiency virus or arise following immunosuppressive therapy administered after organ transplantation or to treat connective tissue diseases such as rheumatoid arthritis. It was recently discovered that various diseases or therapeutic modalities that induce a state of immunosuppression may cause virally driven lymphoproliferations. This book summarizes for the first time this group of immunodeficiency-associated lymphoproliferations.

This collection of translations of some of Koch's important essays represents an important first. It includes three of his essays on anthrax, three on tuberculosis, two on cholera, one on wound infections, and a relective essay entitled "On Bacteriological Research."
