Identifying Helicobacter infection as the leading cause of peptic ulcer disease and gastric cancer has dramatically altered the treatment of these disease states. Over the last several decades, scientists have come to understand that the interplay between the bacteria, the host, and the environment all contribute to the clinical outcome of infection. In Helicobacter Species: Methods and Protocols, expert researchers in the field detail many of the methods and which are now commonly used to study Helicobacter infection. These include protocols and methods that have evolved over time, and standards across the field have been established which are essential for optimal outcomes and to allow comparison of data across different laboratories. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Helicobacter Species: Methods and Protocols seeks to aid scientists in further study of this crucially important research into Helicobacter research.

This book offers a much-needed discussion on the targeting of biofilm-related infections. Chapters include discussions on the impact of biofilm on medical implants, industrial applications, as well as wound and tissue infections. It also offers discussions on regulatory management for industrial sectors and medical environments. Given that there continues to be a paucity of effective antimicrobial products, devices, and coatings in clinical and industrial use that effectively reduce rates of infection or biofilm-related problems, Targeting Biofilms in Translational Research, Device Development, and Industrial Sectors, offers a fresh and much-needed perspective aimed at helping create healthier controlled environments and safer devices. This comprehensive book is indispensable for industrial and academic translational researchers, device developers, and regulatory experts looking to create more effective antimicrobial products.

As this book. Antibacterial Peptide Protocols, will attest, my enthusi asm for the field of antibacterial peptides is based on a conviction (and I am unashamed to say, prejudice) that these substances are in essence antibiotics produced by the host that then participate in host defense against infectious agents. Because of their capacity to exert antibiotic-like action against patho genic microorganisms (bacteria, fungi, parasites, and viruses), there is reason to believe that these agents will soon be used clinically to treat infectious diseases. In fact, in recent years, biotechnology companies have been formed for the sole purpose of developing antibacterial peptides for clinical use. It should be emphasized that antibacterial peptides will likely play a major role in the treatment of infectious diseases, particularly with the increasing prob lem of multidrug-resistant microbes and the relative dearth of new antibiotics being provided by pharmaceutical companies. The topic of this volume of Methods in Molecular Biology, the diverse methods used in research on antibacterial peptides, is thus quite timely. As the subject of antibacterial peptides develops into its own discipline (something strongly suggested by the explosion in the number of papers published over the past decade), it is essential that reliable techniques and strategies be made available not only to those of us in the field, but also to the newcomers and researchers in complementary disciplines."

Rhodococcus are metabolically versatile actinobacteria frequently found in the environment with potential applications in bioremediation, biotransformations and biocatalysis, among other biotechnological processes. These microorganisms are currently the subject of research in many countries of the world. The number of publications and patents on rhodococci has intensified significantly within the last years. In this context, the knowledge acquired during the last decade about basic aspects of Rhodococcus biology is significant and promising about their future prospects. Several genomic projects of Rhodococcus members are now available and in progress through public and private efforts due to the increasing interest in their use for biotechnology. The large Rhodococcus genomes containing a multiplicity of catabolic genes, a high genetic redundancy of biosynthetic pathways and a sophisticated regulatory network reflect the complexity of Rhodococcus biology. The combination of functional genomics studies with biochemical and physiological knowledge is providing new insights, which will enable the biotechnological use of rhodococci. This Microbiology Monographs volume provides a thorough review of many aspects of biochemistry, physiology and genetics of Rhodococcus, in the context of new genomic information. Expert international scientists contributed with reviews on the extraordinary capability of Rhodococcus genus for biodegradation of diverse compounds and bioremediation, biosynthesis of lipids and biosurfactants, adaptation and tolerance to solvents, interaction with metals and biotechnological applications. Chapters dealing with taxonomy, genomes and plasmids, and oligotrophic and central metabolism are also included in this volume. Moreover, the book includes basic aspects of the phytopathogenic R. fascians.

Escherichia coli is a facultative anaerobic Gamma-proteobacterium, which belongs to the family Enterobacteriaceae. While being an important constituent of the normal gut microbiota, specialized E. coli clones have acquired genetic elements that allow them to compete with the endogenous commensals, colonise normally sterile niches and cause disease. E. coli pathotypes can cause intestinal and extra intestinal infections (e.g. UTI, sepsis) and associate with mammalian cells while being extra- or intra-cellular. In recent years, E. coli infections have become a serious clinical problem, due to the rapid spread of antibiotic resistance. Thus, infections with intestinal E. coli (e.g. E. coli O104) or extraintestinal pathogenic strains (e.g. E. coli ST131) are becoming difficult to treat and are often lethal. Consequently, there is a pressing need to develop alternative control measures, including the identification of new drug targets and development of vaccines that offer lasting protection. This volume focuses on several types of E. coli infections (intestinal and extraintestinal), virulence factors, and E. coli pandemics. It addresses the problem of antibiotic resistance, and a dedicated chapter discusses the need to develop alternative control measures. Given its depth and breadth of coverage, the book will benefit all those interested in the biology, genetics, physiology and pathogenesis of E. coli, and in related vaccine development.

This book discusses Prosthetic Joint Infection (PJI), which remains one of the most common problems necessitating revision arthroplasty. It pursues a multidisciplinary approach, bringing together opinions from the leading experts in the field. The book identifies the potential causes of these infections, provides sound diagnostic criteria guidelines, and explains how these prosthetic infections are managed from orthopedic surgery, clinical and diagnostic perspectives. PJI can lead to multiple revision surgeries and significant patient morbidity. Periprosthetic infection rates remain around 1-2% after primary total hip and knee arthroplasty and account for approximately 7-12% of all revision cases. Orthopedic hardware infections are much-feared and costly complications that can occur when these devices are implemented both in traumatic cases as well as in joint replacement surgery. Because these infections can lead to higher morbidity, it is important to understand their pathophysiology and the principles behind their diagnosis and initial treatment. The pathogenesis of these kinds of infections is intimately connected to the biofilm-producing trait characteristic of many microorganisms, which can have a critical effect on the likely success of treatments. The book offers a unique guide for all scientists working in arthroplasty who are seeking an update on the field, and for newcomers alike.

Nitrogen fixation research is presented as a rapidly developing, synergistic area of modern science, using the methods of, and accumulating data from, many fundamental branches of biology and chemistry.

Bacteria as Multicellular Organisms is the first book devoted specifically to multicellular aspects of bacterial life. Contrary to conventional wisdom, which treats bacteria as autonomous single cells, this book shows how bacteria are sentient, interactive organisms with an unexpectedly broad repertoire of chemical and physical mechanisms for signalling each other and organizing themselves into multicellular aggregates with novel properties. The book has been compiled from reports by specialists in a variety of disciplines from genetics and microbiology to environmental engineering and biotechnology. This interdisciplinary approach reflects the growing importance of bacteria as key experimental material for investigating phenomena common to many fields in contemporary science: communication, complexity, self-organization, and pattern formation. The impact of bacterial multicellularity will affect such diverse areas as evolutionary population biology, non-linear dynamics, and information science.

This book provides a comprehensive overview of pertussis - also known as whooping cough. The first part discusses the evolution the genus Bordetellae and the molecular epidemiology of B. pertussis, while the following chapters focus on the role of B. pertussis virulence factors in infection and disease and on the mechanisms of the immune response to infection and vaccination. The book also explores the prevention and control of the disease as well as its clinical management, with the finally section addressing vaccination, from improved immunization strategies to novel vaccines. Pertussis remains one of the most poorly controlled vaccine-preventable diseases around the globe. Universal vaccination has dramatically reduced its incidence but has failed to bring it completely under control. In recent decades, changes in pertussis epidemiology have been noted, likely related to the use of acellular pertussis vaccines, which in many countries have replaced older-generation, whole-cell pertussis vaccines. Several years after their introduction, it is becoming apparent that immunity conferred by acellular vaccines wanes more rapidly than expected. Unlike whole-cell vaccines, acellular vaccines, while protecting against the disease, do not seem to prevent colonization and transmission. Increasing incidence among adolescents and adults makes them a reservoir for transmission to unimmunized infants, who in turn are at risk of severe disease and death. This book is a valuable resource for researchers and clinicians in the field of medical microbiology, vaccine research and infectious diseases.

Quorum sensing (QS) describes a chemical communication behavior that is nearly universal among bacteria. Individual cells release a diffusible small molecule (an autoinducer) into their environment. A high concentration of this autoinducer serves as a signal of high population density, triggering new patterns of gene expression throughout the population. However QS is often much more complex than this simple census-taking behavior. Many QS bacteria produce and detect multiple autoinducers, which generate quorum signal cross talk with each other and with other bacterial species. QS gene regulatory networks respond to a range of physiological and environmental inputs in addition to autoinducer signals. While a host of individual QS systems have been characterized in great molecular and chemical detail, quorum communication raises many fundamental quantitative problems which are increasingly attracting the attention of physical scientists and mathematicians. Key questions include: What kinds of information can a bacterium gather about its environment through QS? What physical principles ultimately constrain the efficacy of diffusion-based communication? How do QS regulatory networks maximize information throughput while minimizing undesirable noise and cross talk? How does QS function in complex, spatially structured environments such as biofilms? Previous books and reviews have focused on the microbiology and biochemistry of QS. With contributions by leading scientists and mathematicians working in the field of physical biology, this volume examines the interplay of diffusion and signaling, collective and coupled dynamics of gene regulation, and spatiotemporal QS phenomena. Chapters will describe experimental studies of QS in natural and engineered or microfabricated bacterial environments, as well as modeling of QS on length scales spanning from the molecular to macroscopic. The book aims to educate physical scientists and quantitative-oriented biologists on the application of physics-based experiment and analysis, together with appropriate modeling, in the understanding and interpretation of the pervasive phenomenon of microbial quorum communication."

Pulses have played a major role in human diet and are considered a rich source of proteins. But, the major constraints in achieving the yield of pulses are the occurrences of various diseases and pests. Hence, there is a need to understand major fungal pathogens and their management strategies for sustainable agriculture. The major pulse crops in India and other Asian countries are bengal gram, pigeon pea, black gram, green gram, lentil and peas, which are attacked by several pathogens that cause considerable crop damage. Bengal gram is affected mainly by wilt (Fusarium oxysporum f. sp. ciceri), blight (Mycosphaerella pinodes) and rust (Uromyces ciceris-arietini). The main diseases of pigeon pea are wilt (Fusarium oxysporum) and Phytophtora stem blight (Phytophthora drechsleri f. sp. cajani). Powdery mildew (Erysiphe polygoni) and rust (Uromyces vicia-fabae) are the most important diseases affecting the production of pea. This volume offers details like symptoms, distribution, pathogens associated, predisposing factors and epidemiology, sources of resistance and holistic management of diseases with particular reference to those of economic importance. Several minor diseases of lentil, green gram and of black gram are discussed with their detailed and updated information. This volume provides pooled information regarding the management of major fungal phytopathogens affecting pulses.

Microbial relationships with all life forms can be as free living, symbiotic or pathogenic. Human beings harbor 10 times more microbial cells than their own. Bacteria are found on the skin surface, in the gut and other body parts. Bacteria causing diseases are the most worrisome. Most of the infectious diseases are caused by bacterial pathogens with an ability to form biofilm. Bacteria within the biofilm are up to 1000 times more resistant to antibiotics. This has taken a more serious turn with the evolution of multiple drug resistant bacteria. Health Departments are making efforts to reduce high mortality and morbidity in man caused by them. Bacterial Quorum sensing (QS), a cell density dependent phenomenon is responsible for a wide range of expressions such as pathogenesis, biofilm formation, competence, sporulation, nitrogen fixation, etc. Majority of these organisms that are important for medical, agriculture, aquaculture, water treatment and remediation, archaeological departments are: Aeromonas, Acinetobacter, Bacillus, Clostridia, Enterococcus, Pseudomonas, Vibrio and Yersinia spp. Biosensors and models have been developed to detect QS systems. Strategies for inhibiting QS system through natural and synthetic compounds have been presented here. The biotechnological applications of QS inhibitors (QSIs) in diverse areas have also been dealt with. Although QSIs do not affect growth and are less likely to impose selective pressure on bacteria, however, a few reports have raised doubts on the fate of QSIs. This book addresses a few questions. Will bacteria develop mechanisms to evade QSIs? Are we watching yet another defeat at the hands of bacteria? Or will we be acting intelligently and survive the onslaughts of this Never Ending battle?

Described as the earliest, simplest life forms, with unlimited metabolic versatility, bacteria are ideally suited to answer some very fundamental questions on life and its processes. They have been employed in almost all fields of biological studies, including Genetics. The whole edifice of science of Genetics centers around three processes: the generation, expression, and transmission of biological variation, and bacteria offer immediate advantages in studying all the three aspects of heredity. Being haploid and structurally simple, it becomes easy to isolate mutations of various kinds and relate them to a function. The availability of such mutants and their detailed genetic and biochemical analyses lead to a gamut of information on gene expression and its regulation. While studying the transmission of biological variation, it is clear that unlike their eukaryotic counterpart, a more genetic approach needs to be employed. Transmission of genetic information in most eukaryotic organisms rests on sexual reproduction that allows the generation of genetically variable offspring through the process of gene recombination. Even though bacteria show an apparent preference for asexual reproduction, they too have evolved mechanisms to trade their genetic material. In fact, bacteria not only could acquire many genes from close relatives, but also from entirely distant members through the process of horizontal gene transfer. Their success story of long evolutionary existence will stand testimony to these mechanisms. While teaching a course on Microbial Genetics to the post-graduate students at Delhi University, it was realized that a book devoted to bacterial genetics may be very handy to the students, researchers, and teachers alike. A strong foundation in genetics also helps in comprehending more modern concepts of molecular biology and recombinant DNA technology, always a favorite with the students and researchers. Planning the format of the book, emphasis has been laid on the generation and transmission of biological variability. The omission of expression part is indeed intentional because lots of information is available on this aspect in any modern biology book. The contents are spread over seven chapters and the text is supported with figures/tables wherever possible. The endeavor has been to induce the readers to appreciate the strength of bacterial genetics and realize the contribution of these tiny organisms to the growth of biological sciences as a whole and genetics in particular.

Insect-transmitted rickettsiales diseases are significant sources of morbidity and mortality all over the world. Their incidence has been increasing in recent years in large part due to climate change and the movement of animals carrying the insect vectors. Currently there are no effective vaccines against diseases caused by members of the order Rickettsiales. Rickettsiales diseases are often misdiagnosed; this book is intended to serve as a tool for their understanding and diagnosis. Rickettsiales covers the seven main genera: Anaplasma, Ehrlichia, Midichloria, Neorickettsia, Orientia, Rickettsia and Wolbachia. Discussion of each genus includes immunology and molecular biology of host-pathogen interactions, epidemiology and diagnosis, and vaccination strategies and therapies.

This book discusses the decoding of the lytic mechanism of an -helical pore-forming toxin, YaxAB, composed of two different subunits. Pore-forming toxins (PFTs) are among the most common bacterial toxins. They are produced by a variety of pathogens, which infect a wide range of organisms including plants, insects and humans. Yet the maturation of these particles and the structural changes required for pore formation are still poorly understood for many PFT families. Using a diverse panel of biochemical and structural techniques, including X-ray crystallography and cryo-electron microscopy, Dr. Brauning and colleagues have succeeded in identifying the mechanistic contributions of the two toxin components and elucidating the lytic state of the pore complex. The results of this thesis on the YaxAB system are applicable to orthologues from agriculturally relevant insect pathogens, and offer valuable structural and mechanistic insights to inform future bioengineering efforts.

The Third International Conference on Haemophilus, Actinobacillus, and Pasteurella (HAP94) was held in July and August at the Edinburgh Conference Centre, Heriot-Watt University, Riccarton Campus, Edinburgh, Scotland, UK. Previous conferences in 1981, Copenhagen, and 1989, Guelph, had indicated widespread interest in this group of pathogenic bacteria and the timing of the Edinburgh conference was prompted by the major advances in our knowledge of the HAP group that had occurred in the five years since the Guelph meeting. These organisms are considered as a group because of their close relationship in an evolutionary sense and because of the similarities in the types of diseases that they preduce. The main objectives of the meeting were to review and discuss current knowledge and present experimental findings relating to the fundamental, applied, clinical, and therapeutic aspects of disease research involving the HAP group of organisms. HAP 94 was attended by 160 delegates from around the world and included many of the foremost researchers studying HAP organisms. The conference was structured around 16 talks from invited speakers who covered key areas of HAP research including taxonomy, mechanisms of pathogenesis, animal disease models, virulence factors, molecular biology, immunolgy, antigen analyses, and experimental and commercial vaccine development. The talks provided a review of the current state of research in each field and allowed each speaker to focus on his or her personal research interests.
