The human immunodeficiency viruses (HIVs), in particular HIV-1, are the causative agent responsible for the current worldwide epidemic of acquired immunodeficiency syndrome (AIDS). A major effort has thus been underway over the past two decades to understand and control this pathogen. During this time, an enormous knowledge base has accumulated regarding the role of viral factors in the HIV-1 life cycle, and the interaction of HIV-1 with the host cell is becoming increasingly understood. Certain features of HIV, for example its ability to infect non-dividing cells, are being exploited in the development of novel gene therapy vehicles. This volume provides an overview of the current information regarding the HIV replication cycle and will serve as an introduction to subsequent chapters that address specific aspects of lentiviral-based gene therapy.

Venezuelan equine encephalitis (VEE) virus was first isolated in 1938 by Kubes and Rios (1) from the brain of a horse which died during an epizootic of a previously unrecognized disease in Venezuela. VEE-related viruses were subsequently isolated during t~e period of 1943-1963 in Venezuela, Colombia, Peru, Trinidad, Brazil, Surinam, Argentina, Panama, Mexico, and the United States (2) * Shope et ~. (3) fi rst defi ned the vi ru ses in the VEE comp 1 ex t-y showing serological relationships between classical VEE, ~lucambo, and Pixuna viruses. Young and Johnson (2) serologically characterized a variety of VEE isolates and proposed that the complex t>e divided into four subtypes (I, II, III, and IV). Viruses in subtype I were divided into five variants designated IA through IE. During 1069-1~71 a VEE epizootic-epidemic occurred in South America, Central America, and the United States involving a subtype lAB virus which caused high mortality among equines and human d i sea se (4). Venezuelan equine encephalitis viruses are alpha-togaviruses w~ic~ contain a positive strand rit>onucleic acid genome enclosed in an icosa~edral nucleocapsid. The virion has an envelope which contains blO glycoproteins: E2 of 5F,000 daltons (gp56) and E1 of ~O,OOO daltons (gp50) (5,6). Viral neutralization (N) and hemagglutiration (HA) sites have been placed on E2 by the use of monospecific rabtdt antisera and monoclonal antibodies specific for purified viral structural proteins (7-10). Only anti-E2 antisera neutralized virus infectivity or blocked virus hemagglutination.

Spirochetes comprise a fascinating group of bacteria. Although diverse in terms of their habitat, ecology and infectivity for vertebrate and non-vertebrate hosts, they are often considered together because of their similar cellular morphologies. This volume brings together an international group of experts to provide essential insights into spirochete biology, with an emphasis on recent advances made possible by the availability of genome sequences. As such, it offers a valuable resource for microbiologists and other scientists with an interest in spirochete biology.

The study of viruses necessarily involves dissecting the intimate details of cellular pathways. Viruses have often been employed as tools in studying cellular pathways, as was done by early retrovirologists such as Peyton Rous in attempting to understand the mechanism of cellular transformation and oncogenesis. On the other side of the coin, virologists seek to de?ne those cellular elements interacting intimatelywiththeir virus ofinterestinorder to better understand viral replication itself, and in some cases to develop antiviral strategies. It is in the intersection of virology and cell biology that many of us ?nd the most rewarding aspects of our research. When a new discovery yields insights into basic cellular mechanisms and presents new targets for int- vention to ?ght a serious pathogen, the impact can be high and the excitement intense. HIV has been no exception to the rule that viruses reveal many basic aspects of cellular biology. In recent years, in part because of the importance of HIV as a major cause of human suffering, numerous cellular processes have been elucidated through work on processes or proteins of this human retrovirus. The excitement in this ?eld is especially well illustrated by the discovery of new innate means of resisting viral replication, such as the work on APOBEC3G, TRIM5a, and BST-2/ tetherin presented in this volume.

This volume looks at the different aspects involved in controlling microbial growth and the techniques employed in obtaining sterile surfaces. It covers research on coatings, nano-materials, herbal materials, naturally occurring antimicrobials in designing antimicrobial surfaces. It discusses issues of antibiotic resistance, synthesis techniques, toxicity, and current and potential applications of antimicrobial surfaces, and this book will serve as a useful reference to a broad range of scientists, industrial practitioners, graduate and undergraduate students, and other professionals in the fields of polymer science and engineering, materials science, surface science, bioengineering and chemical engineering.

How does it feel to confront a pandemic from the inside, one patient at a time? To bridge the gulf between a perilously unwell patient in quarantine and their distraught family outside? To be uncertain whether the protective equipment you wear fits the science or the size of the government stockpile? To strive your utmost to maintain your humanity even while barricaded behind visors and masks? Rachel is a palliative care doctor who looked after the most gravely unwell patients on the Covid-19 wards of her hospital. Amid the tensions, fatigue and rising death toll, she witnessed the courage of patients and NHS staff alike in conditions of unprecedented adversity. For all the bleakness and fear, she found that moments that could stop you in your tracks abounded. People who rose to their best, upon facing the worst, as a microbe laid waste to the population. Her new book, Breathtaking, is an unflinching insider's account of medicine in the time of coronavirus. Drawing on testimony from nursing, acute and intensive care colleagues - as well as, crucially, her patients - Clarke argue that this age of contagion has inspired a profound attentiveness to - and gratitude for - what matters most in life.

This book highlights cutting-edge studies in the development of cell-inspired biomaterials and synthetic materials that manipulate cell functions and provide the next generation with contemporary tools for treating complex human diseases. It explores the convergence of synthetic materials with cell and molecular biology and surveys how functional materials, when patterned with spatial and temporal precision, can be used effectively to maintain cell proliferation and phenotype in vitro, to trigger specific cell functions, and to redirect cell-fate decisions. Human stem cells are a frequently discussed subject in this book. This is an ideal book for students, cell biologists, researchers interested in interdisciplinary research, and biomedical engineers. This book also: Highlights successfully developed technologies in cell engineering that make possible new therapeutic development for previously untreatable conditions Covers topics including bio-inspired micro patterning, DNA origami technology, synthetic NOS inspired by compartmentalized signaling in cells, and light-induced depolarization of the cell membrane Illustrates in detail the use of stem cells and synthetic scaffolds to model ethically sensitive embryonic tissues and organs

Intensive care is a rapidly changing area of medicine, and after four years from the 2nd edition the volume editors and authors have deemed necessary to update it. In the recent years, in fact, five new randomised controlled trials and five new meta-analyses demonstrate that selective decontamination of the digestive tract SDD] is an antimicrobial prophylaxis to prevent severe infections of not only lower airways but also of blood. Additionally, SDD has been shown to reduce inflammation including multiple organ failure and mortality. An intriguing observation is the evidence that SDD using parenteral and enteral antimicrobials reduces rather than increases antimicrobial resistance. Moreover, a new chapter on microcirculation had been added.

The volume will be an invaluable tool for all those requiring in depth knowledge in the ever expanding field of infection control.

This book intends to report the new progress of pseudotyped viruses, including the construction of pseudotyped viruses with different strategies or vectors for most important viruses. Especially for emerging viruses, optimization of the condition and parameters for assay development based on the pseudotyped viruses and widely application as surrogate of authentic virus to study the biological functions of virus, detection of neutralizing antibody, screening viral entry inhibiters, and others. It includes most pseudotyped viruses that have the protein of the target virus on the surface of the parent virus with incomplete genome. The book is likely to be of interest to all researchers in the field of virology, vaccine, and anti-viral drug development and evaluation.

An understanding of virus infection and the underlying role of the immune system in protection against these diseases is vital in today 's medical climate. Previously, only symptoms could be treated, as there were no antiviral therapies. The increasing amounts of research and the huge number of discoveries of immunologic agents and pathways has led to the opportunity to look to the basic physiology of the various disease process as never before. This book is designed to provide the clinician with a thorough and yet approachable textbook describing the relationships between immunology, virology and the disease process.

Dr. Lee Know does a brilliant job shedding light on this once ignored organelle and shows us how to care for our most important metabolic system. Dr. Nasha Winters, co-author of The Metabolic Approach to Cancer From infertility to aging to cancer and neurological disease, Dr. Lee Know will teach you that mitochondria play a central role in much that we care about in health and disease. Stephanie Seneff, senior research scientist, MIT Why do we age? Why does cancer develop? What's the connection between heart failure and Alzheimer's disease or infertility and hearing loss? Can we extend lifespan and if so, how? What is the Exercise Paradox? Why do antioxidant supplements sometimes do more harm than good? Many will be amazed to learn that all these questions, and many more, can be answered by a single point of discussion: mitochondria and bioenergetics. In Mitochondria and the Future of Medicine, Naturopathic Doctor Lee Know tells the epic story of mitochondria, the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy. By understanding how our mitochondria work, in fact, it is possible to add years to our lives, and life to our years. Current research, however, has revealed a dark side: many seemingly disconnected degenerative diseases have tangled roots in dysfunctional mitochondria. However, modern research has also endowed us with the knowledge on how to optimise its function, which is of critical importance to our health and longevity. Lee Know offers cutting-edge information on supplementation and lifestyle changes for mitochondrial optimisation, such as: CoQ10 D-Ribose Cannabinoids Ketogenic dietary therapy Mitochondria and the Future of Medicine is an invaluable resource for practitioners interested in mitochondrial medicine and the true roots of chronic illness and disease, as well as anyone interested in improving their health.

It has become apparent that the genomes of many organisms are characterized by unique patterns of DNA methylation which can differ from genome segment to genome segment and cell type to cell type. These patterns can be instrumental in determining cell type and function. Thus, it is not surprising that studies on the role of DNA methylation now occupy center stage in many fields of biology and medicine such as developmental biology, genetic imprinting, genetic disease, tumor biology, gene therapy, cloning of organisms and others. Once again, basic research in molecular biology has provided the essential foundation for investigations of biomedical problems.

Antimicrobial resistance (AMR) is a global public health threat that needs immediate attention and action from the scientific community. This book compiles and presents the latest and most important aspects of AMR, including the biology involved, its persistence and spread, and novel approaches to tackle this threat. The book first describes the mechanisms and spread of AMR, and then discusses the various approaches and strategies for combating it. Important topics include, microbial pathogenesis, AMR traits and major mechanisms underlying drug-resistance and the emerging strategies and technologies for combating AMR. Emphasis has been given on current developments about natural products including potent phyto-molecules, antimicrobial peptides and endophytes effective against the drug-resistant microbes and target the main drug-resistance determinants (efflux pumps, biofilms, quorum sensing, plasmids, etc.) in these bacterial pathogens. Other exciting topics include applications of nanomaterials in tackling AMR and CRISPR-Cas based precise sequence-specific antimicrobials. This informative book is meant for students and researchers in basic and medical microbiology and biotechnology. It is also useful to public health professionals and industry experts involved in AMR research and related drug-designing.

Multiple demographic or economic parameters contribute to the origin of emerging infections, for example: poverty, urbanization, climate change, conflicts and population migrations. All these factors are a challenge to assess the impact (present and future) of parasitic diseases on public health. The intestine is a major target of these infections; it is a nutrient-rich environment harbouring a complex and dynamic population of 100 trillion microbes: the microbiome. Most researches on the microbiome focus on bacteria, which share the gut ecosystem with a population of uni- and multi cellular eukaryotic organisms that may prey on them. Our interest focuses on the families of eukaryotic microbes inhabiting the intestine, called "intestinal eukaryome", that include fungi, protists and helminths. Knowledge on the reciprocal influence between the microbiome and the eukaryome, and on their combined impact on homeostasis and intestinal diseases is scanty and can be considered as an important emerging field. Furthermore, the factors that differentiate pathogenic eukaryotes from commensals are still unknown. This book presents an overview of the science presented and discussed in the First Eukaryome Congress held from October 16th to 18th, 2019 at the Pasteur Institute in Paris. This book covers the following topics: Phylogenetic, prevalence, and diversity of intestinal eukaryotic microbes; and their (still enigmatic) historical evolution and potential contributions to mucosal immune homeostasis. Integrative biology to study the molecular cell biology of parasite-host interactions and the multiple parameters underlining the infectious process. The exploitation of tissue engineering and microfluidics to establish three-dimensional (3D) systems that help to understand homeostasis and pathological processes in the human intestine.

Hepatitis delta virus which causes severe acute and chronic liver disease was discovered following the detection of a novel antigen-antibody system in hepatitis B virus carriers. Currently, HDV is classified as a subviral satellite of hepatitis B virus. However, unlike other satellite viruses, the dependence of HDV on HBV is limited solely to the provision of an envelope of hepatitis B surface antigen for virus assembly. Research into the molecular virology of the HDV life cycle has revealed a fascinating collection of biology. These insights are now beginning to be translated into new potential treatment strategies. There are currently still an estimated 15 million HDV carriers worldwide.

Shortly after the reeognition of the aequired immunodefieieney syndrome (AIDS) in 1981 (1-3), it was hypothesized that herpesviruses may play an important role in the etiology or pathogenesis of this newly identified syndrome (4,5). This theory was based on the faet that infeetion with herpesviruses was a prominent elinieal feature in nearly all patients with AIDS (3-5). Chronie mueocutaneous herpes simplex virus (HSV) infections were one of the first opportunistie infeetions deseribed in patients with AIDS (3), and both cytomegalovirus (CMV) and HSV infections were extremely common in individuals identified to be at highest risk for aequiring AIDS, such as homosexual men, intravenous drug users and hemophiliaes (4-8). CMVand Epstein-Barr virus (EBV) were also prominent infeetions whieh were suspected as possible etiologic agents of the prolonged fever, wasting, and Iymphadenopathy that often precedes AIDS, frequently referred to as the chronie Iymphadenopathy syndrome (9,10). Subsequent elinieal studies have indeed demonstrated that infeetions with HSV, CMV, EBV, and even varieella zoster virus (VZV) are frequent opportunistic infeetions wh ich oeeur among AIDS patients (11-14). Several of the opportunistie infeetions caused by herpesviruses include encephalitis, chorioretinitis, hairy leukoplakia, esophagitis, enteritis, colitis, Burkitt's lymphoma, primary CNS lymphoma, zoster, and there has even been speculation about the role of CMV in the pathogenesis of Kaposi's sareoma (15,16). Furthermore, the herpesviruses, partieularly CMV and EBV have been known to be strongly associated with immunosuppression, partieularly of cell-mediated immune functions, which further supported the hypothesis that herpesviruses may contribute to the immune defects that eharacterize AIDS."

Drug-resistant bacteria ― known as superbugs ― are one of the biggest medical threats of our time. Here, a doctor, researcher, and ethics professor tells the exhilarating story of his race to beat them and save countless lives.

When doctor Matt McCarthy first meets Jackson, a mechanic from Queens, it is in the ER, where he has come for treatment for an infected gunshot wound. Usually, antibiotics would be prescribed, but Jackson’s infection is one of a growing number of superbugs, bacteria that have built up resistance to known drugs. He only has one option, and if that doesn’t work he may lose his leg or even his life.

On the same day, McCarthy and his mentor Tom Walsh begin work on a groundbreaking clinical trial for a new antibiotic they believe will eradicate certain kinds of superbugs and demonstrate to Big Pharma that investment in these drugs can save millions of lives and prove financially viable. But there are seemingly endless hoops to jump through before they can begin administering the drug to patients, and for people like Jackson time is in short supply.

Superbugs is a compelling tale of medical ingenuity. From the muddy trenches of the First World War, where Alexander Fleming searched for a cure for soldiers with infected wounds, to breakthroughs in antibiotics and antifungals today that could revolutionise how infections are treated, McCarthy takes the reader on a roller-coaster ride through the history ― and future ― of medicine. Along the way, we meet patients like Remy, a teenage girl with a dangerous and rare infection; Donny, a retired firefighter with a compromised immune system; and Bill, the author’s own father-in-law, who contracts a deadly staph infection. And we learn about the ethics of medical research: why potentially life-saving treatments are often delayed for years to protect patients from exploitation.

Can McCarthy get his trial approved and underway in time to save the lives of his countless patients infected with deadly bacteria, who have otherwise lost all hope?

This concise, comprehensive guide is divided into two sections; nails and the skin. Each section includes information on the types of infections, aetiology, diagnostic procedures, such as sampling techniques, and therapy, including topical, systemic and adjunctive.

The detection and/or isolation and identification of pathogenic microorganisms is critical for the laboratory diagnosis of infectious diseases. With growth-dependant methods providing reliable means for identifying pathogens, traditional culturing continues to play an integral role in the detection and characterization of known and "new" microbial pathogens. Microbiologists, therefore, rely on a variety of media for the detection, isolation, characterization, and identification of primary and opportunistic microbial pathogens. The Handbook of Media for Clinical and Public Health Microbiology provides a compilation of the formulations, methods of preparation, and applications for media used in clinical and public health microbiology laboratories. It is a significant update to the Handbook of Media for Clinical Microbiology, expanding the coverage to media used for public health epidemiological investigations of disease outbreaks and including media used for the detection of pathogens in foods and environmental samples. Comprising both classic and modern media, the handbook describes almost 1,800 types of media, listed alphabetically, including new media for the cultivation of emerging bacteria, fungi, and viruses that are causing major medical problems around the world. Examples of emerging pathogens are extended-spectrum beta-lactamase (ESBL)-producing bacteria, Escherichia coli O157:H7, methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and carbapenem-resistant Enterobacteriaceae (CRE). Many of the new media contain chromogenic or fluorogenic substrates that permit rapid detection of specific pathogens. The handbook's format allows easy reference to information needed to prepare media for cultivating clinically relevant microorganisms. It also contains descriptions of expected results for organisms that are important for the examination of foods, water, and other

Filling a gap in the literature, this reference provides concise and practical guidelines for the diagnosis and management of sinusitis and furnishes an authoritative outline of our current understanding of the pathophysiology of this condition. Addressing a wide spectrum of issues related to the identification, epidemiology, and etiology of sinusitis, this guide presents detailed illustrations and flowcharts to clarify the interactions between the pathological and physiological processes of sinusitis and illustrate current treatment practices.

With the exception of a few tropical medicine schools worldwide, current medical education programs include almost zero discussion of the interface between infectious diseases and entomology. That is why this book was initially published in the first edition almost 17 years ago. The third edition of this valuable infectious disease entomology book updates all existing chapters with the newest scientific developments described in the medical and entomological literature in addition to covering 10 entirely new topics not addressed in previous editions, which include: * arthropod identification controversies * early beginnings of public health and disease control * red-meat allergy * updates on vaccine development for dengue and malaria * discussion of Chikungunya and Zika viruses * American Boutonnneuse Fever * the newest controversies in Lyme disease * recent findings of viruses in ticks * bed bug bite reactions * Morgellons disease (an imaginary infectious disease)

Megaplasmids are extrachromosomal genetic elements in the size range of 100 kb and larger. They are found in physiologically and phylogenetically diverse groups of bacteria and archaea. By definition, megaplasmids are not essential for the viability of their hosts under all growth conditions, but paradoxically many megaplasmids carry the genetic information for the defining and characteristic traits of the organism in which they reside.

Microbial Megaplasmids reviews our knowledge of the extensively studied representatives, such as the catabolic plasmids of the pseudomonads, the rhizobial Sym plasmids, the Ti plasmids of the genus Agrobacterium and the giant enterobacterial virulence plasmids. It also presents snapshots of more recently discovered megaplasmids. The contribution of megaplasmids to the biology of their hosts is described, highlighting the interactions between megaplasmid and chromosomal genes.

Exploring breakthroughs in fungal detection and control, this book covers fungal nomenclature, population instability, and phylogeny, as well as investigative research on Peronosporomycetes, Zygomycetes, Filamentous Ascomycetes, Basidiomycetous Yeasts, Endomycetes and Blastomycetes, and Miscellaneous Opportunistic Fungi. It offers methods to identify zoopathogenic fungi, analyze reports of putative pathogens, develop methods for detection, isolation, and characterization of pathogenic fungi, evaluate emerging strain-typing techniques, target molecules for diagnostic tests, and examine the patterns and mechanisms of genetic variation.

Only recently have we begun to appreciate the role of microbiome in health and disease. Environmental factors and change of life style including diet significantly shape human microbiome that in turn appears to modify gut barrier function affecting nutrient & electrolyte absorption and inflammation. Approaches that can reverse the gut dysbiosis represent as reasonable and novel strategies for restoring the balance between host and microbes. In the book, we offer summary and discussion on the advances in understanding of pathophysiological mechanisms of microbial host interactions in human diseases. We will not only discuss intestinal bacterial community, but also viruses, fungi and oral microbiome. Microbiome studies will facilitate diagnosis, functional studies, drug development and personalized medicine. Thus, this book will further highlight the microbiome in the context of health and disease, focusing on mechanistic concepts that underlie the complex relationships between host and microbes.

Leading basic researchers and clinical scientists describe in detail a wide variety of established and cutting-edge techniques they have developed to study the lifecycle and biological properties of the human papillomavirus.
