Recent years have seen unprecedented outbreaks of avian influenza A viruses. In particular, highly pathogenic H5N1 viruses have not only resulted in widespread outbreaks in domestic poultry, but have been transmitted to humans, resulting in numerous fatalities. The rapid expansion in their geographic distribution and the possibility that these viruses could acquire the ability to spread from person to person raises the risk that such a virus could cause a global pandemic with high morbidity and mortality. An effective influenza vaccine represents the best approach to prevent and control such an emerging pandemic. However, current influenza vaccines are directed at existing seasonal influenza viruses, which have little or no antigenic relationship to the highly pathogenic H5N1 strains. Concerns about pandemic preparedness have greatly stimulated research activities to develop eff- tive vaccines for pandemic influenza viruses, and to overcome the limitations inh- ent in current approaches to vaccine production and distribution. These limitations include the use of embryonated chicken eggs as the substrate for vaccine prod- tion, which is time-consuming and could involve potential biohazards in growth of new virus strains. Other limitations include the requirement that the current inac- vated influenza vaccines be administered using needles and syringes, requiring trained personnel, which could be a bottleneck when attempting to vaccinate large populations in mass campaigns. In addition, the current inactivated vaccines that are delivered by injection elicit limited protective immunity in the upper respiratory tract where the infection process is initiated.
"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.
This book focuses on host-pathogen interactions at the metabolic level. It explores the metabolic requirements of the infectious agents, the microbial metabolic pathways that are dedicated to circumvent host immune mechanisms as well as the molecular mechanisms by which pathogens hijack host cell metabolism for their own benefit. Finally, it provides insights on the possible clinical and immunotherapeutic applications, as well as on the available experimental and analytical methods. The contributions break new ground in understanding the metabolic crosstalk between host and pathogen.
Handbook of Animal Models of Infection is a complete revision of a
three-volume text that was published in 1986. It incorporates the
major advances in the field during the past decade, in particular
those concerning molecular biological procedures and new models
that have been developed. It focuses on both methods and
techniques, which makes it an essential and comprehensive reference
as well as a benchtop manual. The Handbook will help investigators
save time and effort in formulating an approach to test a new
potential therapeutic agent or combination of agents for "in vivo"
efficacy and to position the therapy for specific infections where
it may have therapeutic promise. The book is divided into five
sections; the first covering the general methodologies, followed by
sections describing experimental bacterial, mycotic, parasitic, and
viral infections.
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.
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.

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.
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.

One of the most exciting developments in the field of bacterial pathogenesis in recent years is the discovery that many pathogens utilize complex nanomachines to deliver bacterially encoded effector proteins into eukaryotic and prokaryotic target cells to modulate a variety of cellular functions for the pathogen's benefit. These protein-delivery machines include the type III secretion system (T3SS), which is widespread in nature and encoded not only by bacteria pathogenic to vertebrates or plants, but also by bacteria that are symbiotic to plants or insects. Because they are essential virulence factors for many important human pathogens, these systems are emerging as a prime target for the development of new-generation, anti-infective drugs. This book reviews our current understanding of these intriguing injection machines as well as of the closely related T3SS that serves in flagella assembly. Individual chapters focus on regulation, assembly, structure, and function of the type III secretion machine and on the evolution of the secreted effector proteins. Given its scope, this book will appeal to a broad readership, including researchers and teachers in the fields of infectious diseases, host pathogen interactions, plant and animal pathogenesis, and symbiosis.
This book will assemble the views of many of the world's experts in the field of viruses and diabetes. It will look critically at some unanswered questions, in the field. Among these, How do viruses destroy or modify the pancreatic islet? Which viruses are involved? What is the role of virus-induced cytokines> Could vaccines prevent virus-induced diabetes? Until recent technological advances, progress in the understanding of the relationship between viruses and diabetes has been hampered. New technologies are helping shed new light on these mysteries. This will be the first comprehensive volume on this topic.
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 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.
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." These papers clearly reflect the coherence and inter-connectedness of Koch's thought. They include the initial presentation of his ideas and also provide examples of his tenacious and devasting responses to his critics. While they only represent some of the many areas of Koch's interests, they serve as excellent samples of his finest contributions. The volume also includes a long introduction which establishes the historical context of Koch's work and of the particular essays translated here.
One Health is an emerging concept that aims to bring together human, animal, and environmental health. Achieving harmonized approaches for disease detection and prevention is difficult because traditional boundaries of medical and veterinary practice must be crossed. In the 19th and early 20th centuries this was not the case then researchers like Louis Pasteur and Robert Koch and physicians like William Osler and Rudolph Virchow crossed the boundaries between animal and human health. More recently Calvin Schwabe revised the concept of One Medicine. This was critical for the advancement of the field of epidemiology, especially as applied to zoonotic diseases. The future of One Health is at a crossroads with a need to more clearly define its boundaries and demonstrate its benefits. Interestingly the greatest acceptance of One Health is seen in the developing world where it is having significant impacts on control of infectious diseases. "
Conceptually unsavoury, airway mucus is vital to homeostasis in the respiratory tract. In contrast, when abnormal, mucus contributes significantly to the pathophysiology of a number of severe bronchial diseases, including asthma, chronic bronchitis and cystic fibrosis. This volume provides wide ranging and in-depth coverage of the scientific and clinical aspects of airway mucus. It commences with introductory chapters which address the biochemical and molecular biological basis of airway mucus and continues with comprehensive coverage of the various physiological and rheological aspects of respiratory secretions. The clinical aspects of the topic are then considered, with chapters discussing the involvement of mucus secretions in bacterial infection and in hypersecretory diseases of the airway. The volume concludes with a discussion of the therapeutic aspects of the topic, both in terms of the possible approaches to the treatment of mucus hypersecretion and the interaction of these drugs with airway mucus. Written by leading experts in the field, each contribution provides a comprehensive review of its particular subject. Reflecting the latest advances in this important area of respiratory research, this volume will be of great interest to scientists and clinicians working in the field of airway secretions and related areas.
This first volume in a two-volume work enhances readers' understanding of antimicrobial resistance mechanisms in selected bacterial species that cause diseases in major food producing animals. It provides an overview of the current legislation and policies seeking to regulate the authorisation, manufacturing, distribution and use of veterinary antimicrobials in practice in a way that helps to contain the spread of antimicrobial resistance. The focus is put on Europe, without neglecting the global context. Moreover, attention is paid to various uses of antimicrobials in livestock, considering both their risks and benefits, from the distant past to the present. Growth promotion, prophylaxis, metaphylaxis, diagnostics and treatment are discussed not only with regard to food production and animal health, but also considering the One Health concept, which combines public and animal health with environmental aspects. A summary of various systems for monitoring the use of antimicrobials is provided, as well as an overview of the diseases that European veterinarians most often treat with antimicrobials. In closing, the book addresses the complexity of recent measures that are of key importance for antimicrobial stewardship, e.g. biosecurity, vaccination and other preventive tools including the newest technologies like smart farming. The complete two-volume work provides an extensive review of various aspects related to the use of antimicrobials in veterinary medicine, especially considering major food producing species, their most common infectious diseases and causative pathogens, and mainly focusing on the situation in Europe, without ignoring the global context. While Volume I discusses more general aspects of antibiotic use such as regulatory, laboratory and practical issues from different perspectives, Volume II more specifically discusses medical aspects and the use of antimicrobials in cattle, pigs, poultry and horses, as well as pharmacokinetics and pharmacodynamics, two of the most important factors determining the success of treatment. In both volumes, each chapter confronts the reader with open questions to stimulate further discussions and future research on the topics covered.
Scientists often look askance at their colleagues whose research appears too strongly focused on a single gene or gene product. We are supposed to be interested in the "big picture" and excessive zeal in pursuit of a single pixel might seem to border on an obsession that is likely to yield only details. However as this volume of Current Topics in Microbiology and Immunology demonstrates, this is certainly not the case for myc. Intense study of this en- matic proto-oncogene over the last twenty years has only broadened our view of its functions and led to insights into mechanisms relating to transcriptional regulation as well as to cell growth, proliferation, differentiation, apoptosis and organismal development. The myc gene originally came to light as a retroviral oncogene (v-myc) associated with a wide range of acute neoplasms. It was later shown to be a virally transduced cellular gene (c-myc) which is a member of family of on- genes (c-myc,N-myc,L-myc). These family members are themselves subject to a bewildering assortment of genetic rearrangements associated with many different types of tumors derived from many different types of cells. These rearrangements (including chromosomal translocation, viral integration, and gene ampli?cation) act to uncouple expression of the myc family genes from their normal physiological regulators. The chapter by LIU and LEVENS - scribes the key pathways leading to regulation of myc expression, showing that such regulation occurs at several different levels and through multiple mechanisms.
In eukaryotic cells, the nuclear genome and its transcriptional apparatus is separated from the site of protein synthesis by the nuclear envelope. Thus, a constant flow of proteins and nucleic acids has to cross the nuclear envelope in both directions. This transport in and out of the nucleus is mediated by nuclear pore complexes (NPCs) and occurs in an energy and signal-dependent manner. Thus, nucleocytoplasmic translocation of macro molecules across the nuclear envelope appears to be a highly specific and regulated process. Viruses that replicate their genome in the cell nucleus are therefore forced to develop efficient ways to deal with the intracellulZlr host cell transport machinery. Historically, investigation of Polyomavirus replication allowed identification ofsequences that mediate nuclear import, which led subsequently to our detailed understanding of the cellular factors that are involved in nuclear import. Transport ofmacromolecules in the opposite direction, however, is less well understood. The investigation of retroviral gene expression in recent years pro vided the first insights into the cellular mechanisms that regulate nuclear export. In particular, the detailed dissection of the function of the human immunodeficiency virus type I (HIV-I) Rev trans-activator protein identified CRMI, as a hona fide nuclear export receptor. CRM I appears to be involved in the nucleocytoplasmic translocation of the vast majority of viral and cellular proteins that have subsequently been found to contain a Rev-type leucine-rich nuclear export signal (NES)." |
