This volume evaluates the carcinogenic risk to humans posed by infection with human papillomaviruses (HPVs). To date, more than 70 HPV types have been identified, of which over 15 have been reported in cervical cancer biopsies. Worldwide, cervical cancer is the second most common cancer in women. This book also considers the possible involvement of HPV infection in cancers at other sites of the human body.
The First International Symposium on the Interface between Analytical Chemistry and Microbiology: Applications of Chromatography and Mass Spectrometry was held June 1987 at the University of South Carolina, Columbia, SC, U.S.A. The purpose of the "Interface" meeting was to forge connections between analytical chemists and microbiologists that are using chromatography and mass spectrometry to solve common problems. The goals were admirably fulfilled. Nearly a hundred participants from seven European countries, Japan, and the United States participated in hearing twenty-three plenary talks and thirty-six submitted papers and posters. The papers and discussions displayed the breadth and depth of current research applications and revealed future directions. This book "Analytical Microbiology Methods: Chromatography and Mass Spectrometry" is loosely based on some of the presentations and discussions at the meeting. Each chapter describes specific methodology and applications in the context of the relevant scientific background. The present book continues the theme of an earlier book, "Gas Chromatography/Mass Spectrometry Applications in Microbiology," edited by G. Odham, L. Larsson, and P-A. Mardh, published by Plenum Press in 1984.
"Theoretically, one should obtain essentially the same clinical picture from failure of an end-organ to respond to a hormone as from a decreased production or absence of said hormone. " With these words, Fuller Albright began his now classic paper describing a novel disease, pseudo hypoparathyroidism (PHP), and a novel concept, hormone resis- tance as a cause of disease. Soon, other hormone resistance disorders such as nephrogenic diabetes insipidus (NDI) were recognized, and the concept was extended to resistance to other substances such as calcium ions in familial hypocalciuric hypercalcemia (FHH). Later, diseases characterized by excess rather than deficient hormone action such as McCune-Albright syndrome (MAS) and familial male precocious puberty (FMPP) were recognized to be caused by autonomous endocrine hyperfunction. Although many i!!vestigators provided careful and detailed descriptions of the clinical features of these and other related endocrine disorders, an understanding of pathogenesis proved elusive for many years. In just the past few years, we have gone from clinical description to a molecular understanding of these interesting disorders. This remarkable progress reflects a synthe- sis of three distinct, but now overlapping, areas of biomedical research: the aforemen- tioned recognition and careful clinical description of specific diseases, the elucidation of the basic mechanisms of signal transduction, and the application of the powerful tools of molecular biology and genetics. Fundamental studies on the mechanisms of hormone action by Rodbell and colleagues at NIH culminated in the discovery of a major signal transduction pathway involving heterotrimeric G proteins.
Provides a detailed survey of new therapies for autoimmune diseases, exploring the rationale for their use and clinical data regarding their potential benefit. The book emphasizes biological interventions based on the pathogenesis of autoimmunity, ranging from altering tolerance to modifying cytokines and changing lymphocyte function.
The collection of chapters in this proceeding volume reflects the latest research presented at the Aegean meeting on Tumor Microenvironment and Cellular Stress held in Crete in Fall of 2012. The book provides critical insight to how the tumor microenvironment affects tumor metabolism, cell stemness, cell viability, genomic instability and more. Additional topics include identifying common pathways that are potential candidates for therapeutic intervention, which will stimulate collaboration between groups that are more focused on elucidation of biochemical aspects of stress biology and groups that study the pathophysiological aspects of stress pathways or engaged in drug discovery.
Recent outbreaks of swine influenza and avian influenza, along with the remaining and in some cases expanding threats from HIV, dengue virus, and the viruses causing hepatitis, have reinforced the need for rapid, accurate and cost-effective diagnosis of viral disease. Diagnostic Virology Protocols, Second Edition brings the field fully up-to-date with a focus on protocols involving nucleic acid detection, most often through some form of the polymerase chain reaction (PCR). The expert contributors also delve into the key technology of robotics as well as future prospects, such as further refined point-of-care testing and the increasing importance of mathematical modelling. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include brief introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Diagnostic Virology Protocols, Second Edition captures the dramatic changes in the virus diagnostic laboratory in order to better prepare scientists to combat the inevitable threats to public health from future and present infectious diseases.
The book presents current affairs of Sporotrichosis as emergent disease with emphasis on the potential factors associated with genetic polymorphisms in Sporothrix complex. Constitutive and inducible factors play an essential role in the response of the fungal cell to the environment as determinant in the immunopathogenicity, highlighting clinical forms of Sporotrichosis and host immunocompetence. Also, a current issue interest in zoonotic transmission showing that a cat is the animal species most affected by Sporothrix species and their importance in the involvement in the human transmission. Readers can associate parameters of experimental immune response to disease development as well as the diagnostic, prophylaxis, and therapies that can be applied in the near future.
This book covers the wide set of well-regulated virulence factors and defense mechanisms of Pseudomonas aeruginosa focusing on stress responses and the evolution of this opportunistic human pathogen. Pseudomonas aeruginosa is responsible for one out of ten hospital infections. Additionally, this Gram-negative bacterium is accountable for persistent infections in immunocompromised individuals and the leading cause of chronic lung infections in cystic fibrosis patients. This book provides insight on the metabolic versatility of Pseudomonas aeruginosa and its mechanisms for biofilm formation that make this organism highly efficient in causing infections. The book invites the readers to learn more about the intrinsic ability of Pseudomonas aeruginosa to resist a wide variety of antimicrobial agents due to the concerted action of multidrug efflux pumps, antibiotic-degrading enzymes, and the low permeability of bacterial cellular envelopes. Particular focus is put on the evolutionary role of different types of protein-secretion systems in pathogenesis, flagella and their role in chemotaxis and surface sensing, and host-pathogen interactions. This book is a useful introduction to the field for junior scientists interested in the biology and pathogenesis of Pseudomonas aeruginosa. It is also an interesting read for advanced scientists and medical specialists working within this field, providing a broader view of the topic beyond their specific area of specialization.
Bacteria and fungi are able to aggregate together or on surfaces in densely packed microcolonies, facilitated by extracellular polymeric substances for cell protection and stability. These biofilms have proven to be extremely hard to eradicate and remove once established. In chronic infections, this condition can result in a high degree of morbidity and mortality as regular antibiotic treatments are ineffective against biofilms. In industrial facilities, the formation of biofilms can ruin production and result in enormous financial losses. In this book, the current state of antibiofilm research is presented by experts from around the world. Novel, cutting-edge techniques and new optimized strategies based on established methods are discussed in chapters focused on biofilm prevention, treatment and control for the application in clinical, industrial and veterinary settings. Antibiofilm strategies, such as chemical and enzymatic treatments, surface modification and coatings, quorum sensing inhibition and dispersal induction, phage therapy, cold plasma treatment, hyperbaric oxygen treatment, and metal-based nanomedicine are covered, among many others. This book contributes to the UN's Sustainable Development Goal 3: Good Health and Well-Being and is a valuable resource for healthcare professionals, microbiologists, academics and for educators to inform curricula of universities and colleges.
In recent years remarkable progress has been accomplished with respect to our knowledge about bacterial protein toxins. This refers especially to structural aspects of protein toxins but also holds true for genetics, molecular biology and biochemical mechanisms underlying the action of toxins. This volume covers the very current and exciting aspects of up-to-date bacterial toxicology and comprehensively reviews the most important bacterial protein toxins such as the intracellular acting toxins which exhibit enzyme activity, as well as those toxins that interact with cell plasma membranes by damaging the membranes (pore formation) or stimulating cell receptors (superantigens). This is the most current reference work on these important bacterial protein toxins, which are presented from the point of view of different disciplines such as pharmacology, microbiology, cell biology and protein chemistry.
Concerted efforts to study starvation and survival of nondifferentiating vegeta tive heterotrophic bacteria have been made with various degrees of intensity, in different bacteria and contexts, over more than the last 30 years. As with bacterial growth in natural ecosystem conditions, these research efforts have been intermittent, with rather long periods of limited or no production in between. While several important and well-received reviews and proceedings on the topic of this monograph have been published during the last three to four decades, the last few years have seen a marked increase in reviews on starvation survival in non-spore-forming bacteria. This increase reflects a realization that the biology of bacteria in natural conditions is generally not that of logarithmic growth and that we have very limited information on the physiology of the energy-and nutrient-limited phases of the life cyde of the bacterial cello The growing interest in nongrowing bacteria also sterns from the more recent advances on the molecular basis of the starvation-induced nongrowing bacterial cello The identification of starvation-specific gene and protein re sponders in Escherichia coli as weIl as other bacterial species has provided molecular handles for our attempts to decipher the "differentiation-like" responses and programs that nondifferentiating bacteria exhibit on nutrient limited growth arrest. Severallaboratories have contributed greatly to the progress made in life after-log research."
Since the central theme of this book is the transmission of disease agents through the food chain, we will examine influenza viruses from this perspective. Influenza A viruses are found in humans, pigs, horses, sea mammals, and also in wild aquatic and domestic birds 23]. How are they spread? Between mammals, influenza is an airborne infection, but between birds, influenza can be either an airborne or waterborne infection. Influenza viruses of aquatic birds periodically transmit to domestic birds sometimes with catastrophic effects; this transmis sion can be either airborne or waterborne. Less frequently, avian influenza viruses transmit to mammals and three to four times in the past century this transmission has initiated a pandemic of influenza in humans. The method of spread of avian influenza viruses to mammals remains unresolved, but could be either airborne or waterborne. In this report we will consider recent examples of interspecies transmission of influenza A viruses and the possible prevention of emergence of the next human pandemic which is considered imminent. The reservoirs of influenza A viruses The available evidence indicates that aquatic birds are the reservoirs of all 15 subtypes of influenza A viruses. We will first consider the replication of influenza A in aquatic birds. In wild ducks, influenza viruses replicate preferentially in the cells lining the intestinal tract, cause no disease signs, and 8 7 are excreted in high concentrations in the feces (up to 10 ."

Biology of Parasitism is based on the Biology of Parasitism Course at the Marine Biological Laboratory in Woods Hole, Massachusetts. Having just celebrated its 20th offering, this Course has distinguished itself as the premier, world-renowned training ground for future generations of parasitologists. The primary goal of the Course is to attract and introduce the very best and most promising young researchers to the many unresolved problems in parasitology and prepare them for their future as independent investigators in the field. The rigorous program combines state-of-the-art laboratory research with a program of visiting lecturers who bring together the most current research in the field. Since at this time there are no academic institutions that have enough depth in parasitology research or teaching faculty to provide up-to-date and state-of-the-art training, the Course has become, and will remain, a global resource for providing intensive education in modern parasitology. Biology of Parasitism is intended to present a snapshot of the content and spirit of the Biology of Parasitism Course. By presenting a series of chapters that reflect the formal lectures that students receive on a daily basis, as well as the approaches used during the laboratory section of the Course, the editors hope to share some of the science that occurs there. One part of the book presents the experimental component of the Course, in particular the subject matter of the four two-week sessions covering Immunology, Biochemistry, Cell Biology and Molecular Biology of protozoan and helminth parasites. As in the Course, the experimental part is complemented by a number of review-like chapters solicited from the large number of speakers who lecture during the Course.
par Prof. Dr. E. VAN OYE, Bruxelles Les Salmonella constituent un groupe de germes parmi les plus repandus, les plus cosmo- polites et les plus ubiquitaires des microorganismes potientiellement pathogi'mes. On les rencontre chez tous les animaux a sang froid ou a sang chaud, du plus humble puceron aux plus impressionnants des mammiferes tels les baleines ou les e16phants. On les retrouve aussi partout dans Ie milieu ambiant, en particulier dans les eaux superficielles, qu'elles aoient douces ou salees. nest aiae de comprendre que les aliments les plus divera et les produits les plus inattendus en sont parfois contamimls. Non seulement les Salmonella jouent un role de premier plan dans la pathologie humaine et dans la pathologie animale mais egalement, vu leur ubiquiM, dans de nombreux sec- teurs de l'economie et non seulement celui de l'alimentation. La lutte contre les affections que ces germes provoquent - les salmonelloses - est avant tout baaee sur la prevention. Celle-ci, pour etre efficace, demande d'iltre informe aussi exactement que possible, sur l'identite des germes en cause. Or il existe de par Ie monde plus de 2000 especes differentes de Salmonella pouvant presenter d'innombrables varian- tes sur les plans de la serologie, de la biochimie ou de la lysotypie.

The aim of this comprehensively written volume is to provide a baseline of information on the normal microflora at various sites in the body. It focuses on the mouth, upper digestive tract, large intestine, skin, and urinogenital tract. Written in an easy-to-read format, this book highlights the level of detail available. For example, it explains that in the mouth and colon the data are extremely detailed and good quantitative information is available on large numbers of bacterial species. This work analyzes the similarities and differences between the microfloras of the various "internal" surfaces, and discusses the clear value of good taxonomy. It focuses on problems and extended research in the progress at other sites. Because this work researches the advances and discoveries made in specific areas of human microbial ecology, it is an ideal source for all who are involved in microbiology, bacteriology, and infectious diseases.
Infectious diseases caused by bacterial pathogens are a leading cause of human illness and death worldwide. The study of bacterial pathogenesis has changed dramatically over the last decade, as a result of revolutionary changes in biotechnology and our understanding of molecular and cellular biological systems. This volume is structured to emphasize paradigms of infectious disease that have emerged over the last 10 years and provides a fundamental understanding of the complex cellular and molecular processes that are important for bacterial virulence and the infectious disease process. The book highlights key techniques and methodologies that have driven recent discoveries in bacterial pathogenesis, major structures and mechanisms in bacteria that are important for their pathogenesis, the regulation of these virulence determinants by global regulators, and bacterial biowarfare agents.
The discovery of the human T cell leukemia virus type I in the late 1970s heralded a new era in retrovirology. For the first time, it was demonstrated that a retrovirus could play a role in the development of a human disease, in this case adult T cell leukemia (ATL). Several years later, the acquired immunodeficiency syndrome (AIDS) epidemic began, and it was dem- strated that a retrovirus, originally designated the human T cell lymp- tropic virus type 3, was the causal agent of this syndrome. This virus, later named the human immunodeficiency virus type 1 (HIV-1), has since been extensively studied in terms of its pathogenesis as well as its ability to elicit immune responses. In that time, a tremendous amount of information has been obtained about the virus. Although recent drug regimens have been useful in significantly lowering viral loads and perhaps maintaining an asymptomatic state among individuals infected with HIV-1, an established "cure" for AIDS eludes us. In addition, the effective drug therapies are very expensive, and are not available to infected people in the third world, where greater than 90% of new infections occur. Furthermore, the development of viral resistance against the drug therapies is an additional concern. Despite extensive study, no effective vaccine has been developed. One of the problems in developing an effective vaccine against HIV-1 is the ability of the virus, particularly in the immunogenic envelop glycoprotein, to undergo amino acid hypervariability.
