The field of Clinical Microbiology is evolving at a rapid pace, perhaps more so than any other arm of laboratory medicine. This can be attributed to new technology, including high throughput gene sequencing, multiplex molecular assays, rapid evolution of antimicrobial resistance, and discovery of new pathogens. In addition, modern medical procedures, such as solid organ and stem cell transplantation, have resulted in an explosion of infections with agents that historically have been considered to be of low virulence. This issue of Clinics in Laboratory Medicine will highlight some of the advances in diagnostic microbiology, including MALDI-TOF MS, pathogen discovery, and personalized antimicrobial chemotherapy. In addition, one of the papers will focus on implementation of new technologies and how to maximize patient impact of these new methods.

In the relatively few decades since the introduction of HIV into the human population, variants of the virus have diverged to such an extent that, were the discussion about something other than viruses, said variants could easily be classified as different species. This book will consider these evolutionary variations, as well as the different and, at times, opposing theories attempting to explain them. It will compare and contrast the ways in which the immune system and drugs affect the virus's evolution, and the implications of these for vaccine development. The issue will be explored and explained through "ecological genetics," which postulates that all living organisms have, besides rivals, enemies. This is divergent from the more traditional school of "population genetics," which emphasizes that evolution occurs among rival species (or variants thereof) that compete for niches or resources in a fixed, unreactive environment. Both models will be formulated using mathematical models, which will be included in the book. Finally, it will consider the possibilities for designing a vaccine that blocks HIV from escaping the immune system.

Dengue virus (DENV), a mosquito-borne flavivirus, is the causative agent of dengue fever, currently one of the most significant emerging disease challenges to global public health. Although dengue is an old disease, recent decades have seen an unprecedented increase in the geographic range, incidence, and severity of infection. The virus infects 100 million people annually and is endemic in many tropical and sub-tropical regions in the world. At present, neither a licensed vaccine nor anti-viral drugs are available to control dengue disease, prompting a plethora of research initiatives aimed at understanding the molecular and cellular virology, genomics, and evolution of this important virus. This book brings together a panel of expert dengue virologists to produce a timely review of the rapidly-expanding dengue research literature. In addition, the contributors identify the most pressing questions that remain to be answered, thus providing a stimulus for future research. Topics include: evolutionary history * epidemiology * translation and processing of the viral polyprotein * viral replication * the role of the viral untranslated regions * pathogenesis * host response to DENV * development of animal models * DENV-mosquito interactions * dynamics of dengue virus transmission * emergence of DENV from its ancestral, sylvatic cycle * vaccines * novel anti-dengue drugs * and passive immunotherapy. It is essential reading for every dengue virologist and is highly recommended for all flavivirus and arbovirus virologists.

The acknowledgment that viruses are potent biological factors in driving many cancers have seen a dramatic upsurge in recent years in large part to the success of the human papilloma virus vaccine against invasive cervical carcinomas and followed by the awarding of the noble prize in medicine in 2008 to Dr. Harald zurHausen who identified the link between papilloma virus and cervical cancers. Over the last few years there have been some volumes addressing different aspects of viruses and cancers and to some extent focusing on the DNA viruses, more specifically the human DNA viruses. This proposed volume will attempt to review and address the major gaps in current knowledge in DNA viruses as well as RNA viruses bringing a historical perspective of where studies began to a more recent molecular approach and vaccine successes in tumor viruses. We will also cover other known oncogenic viruses associated cancers in other mammals in addition to humans.

The aim of this book is to provide readers with a wide overview of the main healthcare-associated infections caused by bacteria and fungi able to grow as biofilm. The recently acquired knowledge on the pivotal role played by biofilm-growing microorganisms in healthcare-related infections has given a new dynamic to detection, prevention and treatment of these infections in patients admitted to both acute care hospitals and long-term care facilities. Clinicians, hygienists and microbiologists will be updated by leading scientists on the state-of-art of biofilm-based infections and on the most innovative strategies for prevention and treatment of these infections, often caused by emerging multidrug-resistant biofilm-growing microorganisms.

The year 2012 marks the tenth anniversary of the announcement of the genome sequence of the human malaria parasite Plasmodium falciparum and that of its mosquito vector Anopheles. The genome sequences were a result of the Plasmodium falciparum Genome Project. This book covers in detail the biology of malaria parasites and the mosquitoes that transmit the disease, how the Genome Project came into being, the people who created it, and the cadre of scientists who are attempting to see the promise of the Project realized. The promise was: a more complete understanding of the genes of the parasite (and its vector) would provide a rational basis for the development of antimalarial drugs and vaccines, allow a better understanding of the regulation of the complex life cycle in the red blood and liver cells of the human, identify the genes the parasite uses to thwart the host immune response and the ways in which the parasite evades cure by drug treatments, as well as leading to more effective measures of control transmission. The hope was that cracking the genetic code of Plasmodium and Anopheles would reveal the biochemical Achilles heel of the parasite and its vector, leading to the development of novel drugs and better methods of control, and by finding the targets of protective immunity could result in the manufacture of effective vaccines. Through a historic approach, this book will allow for those new to the field, or those with insufficient background in the sciences, to have an easier entry point. Even scientists already working in the field may better appreciate how discoveries made in the past can impact the direction of future research.

The human microbiome is the bacteria, viruses, and fungi that cover our skin, line our intestines, and flourish in our body cavities. Work on the human microbiome is new, but it is quickly becoming a leading area of biomedical research. What scientists are learning about humans and our microbiomes could change medical practice by introducing new treatment modalities. This new knowledge redefines us as superorganisms comprised of the human body and the collection of microbes that inhabit it and reveals how much we are a part of our environment. The understanding that microbes are not only beneficial but sometimes necessary for survival recasts our interaction with microbes from adversarial to neighborly. This volume explores some of the science that makes human microbiome research possible. It then considers ethical, legal, and social concerns raised by microbiome research. Chapters explore issues related to personal identity, property rights, and privacy. The authors reflect on how human microbiome research challenges reigning views on public health and research ethics. They also address the need for thoughtful policies and procedures to guide the use of the biobanked human samples required for advancing this new domain of research. In the course of these explorations, they introduce examples from the history of biomedical science and recent legal cases that shed light on the issues and inform the policy recommendations they offer at the end of each topic's discussion. This volume is the product of an NIH Human Microbiome Project grant. It represents three years of conversations focused on consensus formation by the twenty-seven members of the interdisciplinary Microbiome Working Group. "The microbiome is a relatively new area of medical attention. Ethical issues related to the microbiome have barely been identified, much less carefully analyzed. This volume is an excellent start toward that ethical analysis. Many of the arguments are persuasive and provocative. In particular, some contributors challenge the ethical need for anonymizing microbiome specimens as well as the need for individual informed consent for specific uses of these specimens. I highly recommend this volume for all those interested in the microbiome and in new frontiers in medical ethics." -Leonard M. Fleck, Michigan State University

This volume focuses on the role of sphingosine-1-phosphate (S1P) and its analogs in the induced sequestration of lymphocytes in secondary lymphoid organs or in the microenvironment of tissues involved in infection or autoimmune disease. Initial chapters define the pathways to understand S1P signaling. They cover the organization of signaling systems, the structural biology of the S1P1 receptor, and the chemical and genetic tools that are available and useful to explore this area of research and therapeutics. The later chapters highlight S1P and endothelial integrity, lymphocyte migration in the spleen, and S1P agonist in controlling immunopathologic manifestations of acute respiratory influenza virus infection (in the lung), and its accompanying cytokine storm as well as immunopathologic disease of the central nervous system, including the beginning of treatments in multiple sclerosis. One chapter reveals the possible involvement of other lipid molecules, their use for better understanding lipid signaling, and their potential in the modulation of immune responses.

The huge potential for gene therapy to cure a wide range of diseases has led to high expectations and a great increase in research efforts in this area, particularly in the study of delivery via viral vectors, widely considered to be more efficient than DNA transfection.

Development of new-generation vaccines is now more challenging than ever, as identifying, purifying and evaluating vaccine antigens is a complex undertaking. Most importantly, once the relevant antigens have been identified, key focus then shifts to the development of suitable delivery systems and formulations to achieve maximum in vivo potency with minimum potential side effects. These novel formulations-many of which will be nanoparticulates-can deliver the antigens to the desired site, to the relevant antigen presenting cells, and prevent systemic exposure of the immune potentiators. The proposed book will outline all the critical steps that need to be considered for successful development of various types of nanoparticulate delivery systems for vaccine antigens. These contributions from leading experts in the area of vaccine formulation and delivery systems will tie in what is the most current status, including clinical evaluations with these novel vaccine technologies.
