The reviews will be of interest for scientists in the fields of agriculture, microbiology, soil biology, plant breeding and herbal medicinal products.

Vast numbers of different prokaryotic microorganisms shape the biosphere, with diverse metabolic capabilities. Determination of genome sequences for a wide range of bacteria and archaea now requires an in-depth knowledge of prokaryotic metabolic function to give biochemical, physiological and ecological meaning to the genomic information. This new edition describes up-to-date knowledge of the key metabolic processes that occur under different conditions, and the cellular processes that determine prokaryotic roles in the environment, biotechnology and human health. Essential for students of microbiology, applied microbiology, biotechnology, genomics and systems biology, this advanced textbook covers prokaryotic structure, composition, nutrient transport, biosynthesis and growth. Newly characterised metabolic pathways are included, as well as the latest understanding of metabolic regulation and stress responses. Additionally, the link between energetics, growth and survival is discussed as well as the maintenance of genetic integrity by the bacterial immune system.

The genus Clostridium represents a heterogeneous group of anaerobic spore-forming bacteria, comprising prominent toxin-producing species, such as C. difficile, C. botulinum, C. tetani, and C. perfringens, in addition to well-known non-pathogens like solventogenic C. acetobutylicum. In the last decade, several clostridial genomes have been deciphered and post-genomic studies are currently underway. The advent of newly developed, genetic manipulation tools have permitted functional-based and systems biology analyses of several clostridial strains. Research in this area is at a very exciting stage. In this book, internationally recognized Clostridium experts critically review the most important aspects of clostridial research, providing the first coherent picture of the organism's molecular and cellular biology in this post-genomic era. The first major focus of the book is the genetics and molecular biology of the major clostridial toxins including: botulinum and tetanus neurotoxins, C. difficile large exotoxins, C. perfringens enterotoxin, pore-forming and binary bacterial toxins. Other topics include molecular epidemiology of C. botulinum and C. difficile, metabolic networks in C. acetobutylicum, development of genetic knock-out systems for clostridia, surface structures, anti tumor potential of clostridia, and antibiotic resistance determinants in C. difficile.

The type I interferon (IFN) signaling pathway is well recognized as a pathway activated by viral infections. It is activated by a variety of microbial pattern recognition receptors including the Toll-like receptors, NOD-like receptors and several cytosolic receptors. Activation of the type I IFN pathway leads to the production of both antiviral factors and products that influence immune cell function. More recently it has been shown that bacteria are also capable of activating this pathway. Bacterial Activation of Type I Interferons reviews both the current understanding of how different bacterial species are able to activate this pathway as well as the influence type I IFNs have on the outcome to infection. Several different bacterial species are covered, spanning Gram positive and Gram negative, intracellular, extracellular, and different host infection sites. An introduction to the pathogenesis of each organism is provided, and the signaling molecules involved in the activation of the type I IFN pathway and the role it plays in animal infection models are also covered.

This book provides readers with information on the factors underlying the emergence of infectious diseases originating in animals and spreading to people. The One Health concept recognizes the important links between human, animal, and environmental health and provides an important strategy in epidemic mitigation and prevention. The essential premise of the One Health concept is to break down the silos among the different health professions and promote transdisciplinary collaborations. These concepts are illustrated with in-depth analyses of specific zoonotic agents and with examples of the successes and challenges associated with implementing One Health. The book also highlights some of the challenges societies face in confronting several specific zoonotic diseases. A chapter is included on comparative medicine to demonstrate the broad scope of the One Health concept. Edited by a team including the One Health Initiative pro bono members, the book is dedicated to those studying zoonotic diseases and comparative medicine in both human and veterinary medicine, to those involved in the prevention and control of zoonotic infections and to those in the general public interested in the visionary field of One Health.

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.

This book brings together many of the world's leading experts in the fields of Antarctic terrestrial soil ecology, providing a comprehensive and completely up-to-date analysis of the status of Antarctic soil microbiology. Antarctic terrestrial soils represent one of the most extreme environments on Earth. Once thought to be largely sterile, it is now known that these diverse and often specialized extreme habitats harbor a very wide range of different microorganisms. Antarctic soil communities are relatively simple, but not unsophisticated. Recent phylogenetic and microscopic studies have demonstrated that these communities have well established trophic structuring and play a significant role in nutrient cycling in these cold and often dry desert ecosystems. They are surprisingly responsive to change and potentially sensitive to climatic perturbation. Antarctic terrestrial soils also harbor specialized 'refuge'habitats, where microbial communities develop under (and within) translucent rocks. These cryptic habitats offer unique models for understanding the physical and biological 'drivers' of community development, function and evolution.

Corynebacterium diphtheriae is the classical etiological agent of diphtheria and the type strain of the genus Corynebacterium. While diphtheria of the respiratory tract became rare with the introduction of vaccination programs in industrialized countries, even today several thousand cases per year are reported to the World Health Organization. This shows that diphtheria is not completely eradicated and that reservoirs exist. The book summarizes the latest advances made in understanding C. diphtheriae and the closely related species Corynebacterium ulcerans and Corynebacterium pseudotuberculosis. Topics addressed are genomics of toxigenic corynebacteria, host-pathogen-interaction, detection, surveillance and treatment as well as application aspects.

Bacterial genomics is a mature research interdisciplinary field, which is approached by ecologists, geneticists, bacteriologists, molecular biologists and evolutionary biologists working in medical, industrial and basic science. Thanks to the large diffusion of bacterial genome analysis, Bacterial Pangenomics: Methods and Protocols is able to provide the most recent methodologies about the study of bacterial pangenomes by covering the three major areas: the experimental methods for approaching bacterial pangenomics, the bio informatic pipelines for analysis and annotation of sequence data and finally the methods for inferring functional and evolutionary features from the pangenome. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Bacterial Pangenomics: Methods and Protocols will serve as a field guide for both qualified bacterial genomics investigators who want to update their technical knowledge, for less experienced researchers who want to start working with bacterial genomics and pangenomics, as well as serving as a manual and supplemental textbook for graduate students of genomics and bioinformatics.

This book describes the growing body of information on the epidemiology, clinical manifestations, transmission, pathogenesis, diagnosis, and treatment of Kingella kingae infections in young children. In addition, it covers experimental methods that have been developed to study the microbiology, genetics, and virulence factors of K. kingae, information that provides the foundation for new approaches to treatment and prevention of K. kingae disease. With this content in mind, excerpts from the book will be of relevance for clinicians who care for pediatric patients, for clinical microbiologists who are involved in detecting organisms in clinical specimens, and for scientists who are studying K. kingae in an effort to develop novel targets for antimicrobial therapy and new approaches to prevention. First isolated in the 1960s by Elizabeth O. King, a bacteriologist at the CDC, Kingella kingae was largely ignored over the next two decades as a human pathogen because of its uncommon recovery from patients with disease. However, in recent years K. kingae has been increasingly recognized as a clinically important pathogen in young children, and is currently recognized as the leading cause of osteoarticular infections in young children in a growing number of countries. Research into this organism has grown tremendously over the past 15 years, resulting in a better appreciation of the importance of K. kingae in pediatric patients and of the molecular mechanisms of disease.

This book introduces Planctomycetes bacteria and deals in detail with their unusual structure, physiology, genomics and evolutionary significance. It is a definitive summary of recent knowledge of this important distinctive group of bacteria, microorganisms which challenge our very concept of the bacterium. Planctomycetes, and their relatives within the PVC superphylum of domain Bacteria, including verrucomicrobia and chlamydia, challenge our classical concept of the bacterium and its modes of life and provide new experimental models for exploring evolutionary cell biology and the full diversity of how living cells can be organized internally. Unique among bacteria, they include species possessing cells with intracellular membrane-bounded compartments and a peptidoglycan-less cell wall, and bacteria such as the anammox organisms performing unique anaerobic ammonium oxidation significant for global nitrogen cycle.

Written in the highly successful Methods in Molecular Biology series format, chapters include 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, Host-Bacteria Interactions: Methods and Protocols provide researchers with a comprehensive account of the practical steps necessary for carrying out each protocol successfully.

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?

Streptococci are Gram-positive bacteria that cause a wide spectrum of diseases, such as pharyngitis, necrotizing fasciitis and streptococcal toxic shock syndrome, as well as rheumatic fever and rheumatic heart disease as sequelae. Antibiotics alone have not been able to control the disease and in spite of many efforts an effective vaccine is not yet available. A prerequisite for novel and successful strategies for combating these bacteria is a complete understanding of the highly complex pathogenic mechanisms involved, which are analyzed in this volume. In ten chapters, prominent authors cover various aspects including streptococcal diseases and global burden, epidemiology, adaptation and transmission, and molecular mechanisms of different diseases, as well as sequelae, vaccine development and clinical management. This book will serve as a valuable reference work for scientists, students, clinicians and public health workers and provide new approaches to meeting the challenge of streptococcal diseases.

The discovery that most of the chronic infections in humans, including the oral, lung, vaginal and foreign body-associated infections, are biofilm-based, has prompted the need to design new and properly focused preventive and therapeutic strategies for these diseases. Microbial Biofilms: Methods and Protocols provides a detailed description of the currently available methods and protocols to investigate bacterial and fungal biofilms, exhaustively illustrated and critically annotated in 25 chapters written by authors well known for their experience in the respective fields. The book has joined together microbiologists and specialists in infectious diseases, hygiene and public health involved in exploring different aspects of microbial biofilms as well as in designing new methods and/or developing innovative laboratory protocols. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Microbial Biofilms: Methods and Protocols presents readers with the most established and validated experimental procedures to investigate microbial biofilms.

Over the years of cancer investigation a lot of discoveries in this field were made, and many associations between various biological carcinogens and cancer were revealed. Some of them are credibly determined, thus these infectious agents (human papilloma virus, hepatitis B virus, hepatitis C virus, Epstein-Barr virus, human herpes virus 8, human T-cell lymphotropic virus 1, human immunodeficiency virus, Merkel cell polyomavirus, Helicobacter pylori, Opisthorchis viverrini, Clonorchis sinensis, Schistosoma haematobium) are recognized as carcinogens and probable carcinogens by International Agency for Research on Cancer (IARC). The problem is of large importance, since share of infectious agents-related cancer cases is steadily increasing, reaching 25% according to certain estimates. It is worth noting that many of cancer cases are caused by infectious agents other than "conventional ones" like HPV, EBV, HBV, HCV, H.pylori etc. In recent years, a number of significant breakthroughs in the field were performed, such as the discovery of the microbiota role in cancer causation.

During bacteriology's Golden Age (roughly 1870-1890) European physicians focused on the role of bacteria as causal agents of disease. Advances in microscopy and laboratory methodology - including the ability to isolate and identify micro-organisms - played critical roles. Robert Koch, the most well known of the European researchers for his identification of anthrax, tuberculosis and cholera, established in Germany the first teaching laboratory for training physicians in the new methods. Bacteriology was largely absent in early U.S. medical schools. Dozens of American physicians-in-training enrolled in Koch's course in Germany and many established bacteriology courses upon their return. This book highlights those who became acknowledged leaders in the field and whose work remains influential.

William Watson Cheyne (1852-1932), a surgeon by training and a student of Joseph Lister, was a prominent British bacteriologist who published 60 papers and 13 monographs from 1879 to 1927. A proponent of the idea that bacteriology and medicine were interdependent disciplines, he investigated the causes and treatment of wound infections, tuberculosis, cholera, tetanus and gangrene. In 1897, he organized an historical outline of 19th century bacteriology in five landmark periods of discovery, each defined by the work of an influential figure. This study documents his contributions to the history of microbiology and describes his activities as a laboratory investigator, clinician, surgeon, translator, editor and educator.

The future of agriculture strongly depends on our ability to enhance productivity without sacrificing long-term production potential. An ecologically and economically sustainable strategy is the application of microorganisms, such as the diverse bacterial species of plant growth promoting bacteria (PGPB). The use of these bio-resources for the enhancement of crop productivity is gaining worldwide importance. "Bacteria in Agrobiology: Plant Nutrient Management" focus on the management of plant nutrient to support plant growth and development. The topics treated in this book include mechanisms of plant growth promoting rhizobacteria, zinc and phosphate solubilizing microorganisms, sulfur oxidizing bacteria, ACC deaminase, siderophores, phytohormones, quorum-sensing, biofilms, antibiotics, volatiles, denitrification and integrated nutrient management.

The OHOLO conferences are sponsored by the Israel Institute for Biological Research and take their name from the site of the ?rst meeting on the shores of Lake Kinnereth. The purpose of these meetings is, as it was at their inception over 50 years ago, "to foster interdisciplinary communication between scientists in Israel, and to provide added stimulus by the participation of invited scientists from abroad". The core of the organizers of the OHOLO conferences are scientists from the Israel Institute for Biological Research. From time to time a particular OHOLO conference cooperates with an international scienti?c organization. The present 46th OHOLO Conference marks the resumption of the OHOLO tradition after 8 years of interruption caused by events beyond our control. It is my belief that our uncomp- mising commitment to excellence in research and development in the various areas of science in Israel is essential to our survival in this troubled region. The OHOLO conference tradition is a re?ection of this conviction. The present 46th OHOLO Conference entitled: The Challenge of Highly Pathogenic Microorganisms - Mechanisms of Virulence and Novel Medical Countermeasures intends to address the unique virulence features and ho- pathogen interactions of microorganisms constituting emerging biothreat with emphasis on Y. pestis, B. anthracis, F. tularensis and Orthopox viruses. Accordingly we selected classical microbiological as well as genomic, proteomic & transcr- tomic approaches towards developments of novel prophylactic and post-exposure treatment, as well as updated strategies of diagnostics and bioforensics.
