Research on bacterial adhesion and its significance is a major field involving many different aspects of nature and human life, such as marine science, soil and plant ecology, most importantly, the biomedical field. The adhesion ofbacteria to the food industry, and human tissue surfaces and implanted biomaterial surfaces is an important step in the patho genesis of infection. Handbook 0/ Bacterial Adhesion: Principles, Methods, and Applications is an outgrowth of the editors' own quest for information on laboratory techniques for studying bacte rial adhesion to biomaterials, bone, and other tissues and, more importantly, a response to significant needs in the research community. This book is designed to be an experimental guide for biomedical scientists, biomaterials scientists, students, laboratory technicians, or anyone who plans to conduct bacterial adhesion studies. More specifically, it is intended for all those researchers facing the chal lenge of implant infections in such devices as orthopedic prostheses, cardiovascular devices or catheters, cerebrospinal fluid shunts or extradural catheters, thoracic or abdominal catheters, portosystemic shunts or bile stents, urological catheters or stents, plastic surgical implants, oral or maxillofacial implants, contraceptive implants, or even contact lenses. It also covers research methods for the study of bacterial adhesion to tis sues such as teeth, respiratory mucosa, intestinal mucosa, and the urinary tract. In short, it constitutes a handbook for biomechanical and bioengineering researchers and students at all levels."

In 1898, an Austrian microbiologist Heinrich Winterberg made a curious observation: the number of microbial cells in his samples did not match the number of colonies formed on nutrient media (Winterberg 1898). About a decade later, J. Amann qu- tified this mismatch, which turned out to be surprisingly large, with non-growing cells outnumbering the cultivable ones almost 150 times (Amann 1911). These papers signify some of the earliest steps towards the discovery of an important phenomenon known today as the Great Plate Count Anomaly (Staley and Konopka 1985). Note how early in the history of microbiology these steps were taken. Detecting the Anomaly almost certainly required the Plate. If so, then the period from 1881 to 1887, the years when Robert Koch and Petri introduced their key inventions (Koch 1881; Petri 1887), sets the earliest boundary for the discovery, which is remarkably close to the 1898 observations by H. Winterberg. Celebrating its 111th anniversary, the Great Plate Count Anomaly today is arguably the oldest unresolved microbiological phenomenon. In the years to follow, the Anomaly was repeatedly confirmed by all microb- logists who cared to compare the cell count in the inoculum to the colony count in the Petri dish (cf., Cholodny 1929; Butkevich 1932; Butkevich and Butkevich 1936). By mid-century, the remarkable difference between the two counts became a universally recognized phenomenon, acknowledged by several classics of the time (Waksman and Hotchkiss 1937; ZoBell 1946; Jannasch and Jones 1959).

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.

The enormous advances in molecular biology that have been witnessed in . Not recent years have had major impacts on many areas of the biological sciences least of these has been in the field of clinical bacteriology and infectious disease . Molecular Bacteriology: Protocols and ClinicalApplications aims to provide the reader with an insight into the role that molecular methodology has to play in modern medical bacteriology. The introductory chapter ofMolecular Bacteriology: ProtocolsandCli- cal Applications offers a personal overview by a Consultant Medical Microbio- gist of the impact and future potential offered by molecular methods. The next six chapters comprise detailed protocols for a range of such methods . We believe that the use of these protocols should allow the reader to establish the various methods described in his or her own laboratory. In selecting the methods to be included in this section, we have concentrated on those that, arguably, have greatest current relevance to reference clinical bacteriology laboratories; we have deliberately chosen not to give detailed protocols for certain methods, such as multilocus enzyme electrophoresis that, in our opinion, remain the preserve of specialist la- ratories and that are not currently suited for general use. We feel that the methods included in this section will find increasing use in diagnostic laboratories and that it is important that the concepts, advantages, and limitations of each are th- oughly understood by a wide range of workers in the field .

The discovery of Epstein-Barr virus (EBV) by Epstein, Achong, and Barr, reported in 1964 (Lancet 1:702-703), was stimulated by Denis Burkitt's rec- nition of a novel African childhood lymphoma and his postulation that an infectious agent was involved in the tumor's etiology (Nature194:232-234, 1962). Since then, molecular and cellular biological and computational technologies have progressed by leaps and bounds. The advent of recombinant DNA technology opened the possibilities of genetic research more than most would have realized. Not only have the molecular tools permitted the analyses of viral mechanisms, but, importantly, they have formed the basis for discerning viral presence and, subsequently, viral involvement in an increasing number of diseases. Though in every field of science the search for further knowledge is likely to be a limitless phenomenon, the distinct goal in EBV research, namely, to gain sufficient insight into the viral-host interaction to be able to intercept the pathogenic process, is beginning to be realized. Epstein-Barr virus research has effectively entered the postgenomic era that began with the sequencing of the first strains, cloned in the mid to late 1980s.

Arbuscular Mycorrhiza (AM) is the most common mycorrhizal type involved in agricultural systems, and the most widespread plant root symbiosis. The fungi involved (Glomales) are known to promote plant growth and health by acting as biofertilizers, bioprotectors and bioregulators. The main aim of this book is to provide readers with theoretical and applied knowledge essential for the use of AM fungi in improving plant health and fitness, production of high quality food and in conservation of natural resources. The different chapters target understanding the role of AM fungi in sustainable crop production, discussing ways to improve biological equilibria between microorganisms in the mycorrhizosphere, analysing genetic, physiological, cellular and molecular bases of AM functioning and establishing technologies for inoculum production, according to the regulatory guidelines for application.

Plasmids are fascinating entities which can replicate autonomously in bacterial, archaeal, and eukaryotic cells. They profit from the cellular environment of the host but can also carry a rich diversity of genes which can be beneficial for the host. Plasmids confer the ability to degrade organic compounds and to fix nitrogen. In addition, plasmids carry antibiotic resistance genes and their spread in pathogenic bacteria is of great medical importance. Plasmids are used in molecular studies of various organisms with ramifications in synthetic biology, medicine, ecology, and evolution, as well as basic research in molecular and structural biology. Written by acknowledged experts in the field, this volume provides an up-to-date treatment of the structure, function, and application of plasmids, with a particular emphasis on current and future trends. The book is aimed primarily at research scientists, graduate students, and professional scientists, but will also be of great interest to all

Prokaryotic Toxins - Antitoxins gives the first overview of an exciting and rapidly expanding research field. Toxin - antitoxin (TA) genes were discovered on plasmids 30 years ago. Since then it has become evident that TA genes are highly abundant in bacterial and archaeal chromosomes. TA genes code for an antitoxin that combine with and neutralize a cognate toxin. When activated, the toxins inhibit protein synthesis and cell growth and thereby induce dormancy and multidrug tolerance (persistence). Remarkably, in some species, the TA gene families have undergone dramatic expansions. For example, the highly persistent major human pathogen Mycobacterium tuberculosis has "100 TA loci. The large expansion of TA genes by some organisms is a biological mystery. However, recent observations indicate that TA genes contribute cumulatively to the persistence of bacteria. This medically important phenomenon may thus for the first time become experimentally tractable at the molecular level.

It will provide valuable assistance for graduate students intending to become active in interdisciplinary research.

This first volume in a two-volume work enhances readers' understanding of antimicrobial resistance mechanisms in selected bacterial species that cause diseases in major food producing animals. It provides an overview of the current legislation and policies seeking to regulate the authorisation, manufacturing, distribution and use of veterinary antimicrobials in practice in a way that helps to contain the spread of antimicrobial resistance. The focus is put on Europe, without neglecting the global context. Moreover, attention is paid to various uses of antimicrobials in livestock, considering both their risks and benefits, from the distant past to the present. Growth promotion, prophylaxis, metaphylaxis, diagnostics and treatment are discussed not only with regard to food production and animal health, but also considering the One Health concept, which combines public and animal health with environmental aspects. A summary of various systems for monitoring the use of antimicrobials is provided, as well as an overview of the diseases that European veterinarians most often treat with antimicrobials. In closing, the book addresses the complexity of recent measures that are of key importance for antimicrobial stewardship, e.g. biosecurity, vaccination and other preventive tools including the newest technologies like smart farming. The complete two-volume work provides an extensive review of various aspects related to the use of antimicrobials in veterinary medicine, especially considering major food producing species, their most common infectious diseases and causative pathogens, and mainly focusing on the situation in Europe, without ignoring the global context. While Volume I discusses more general aspects of antibiotic use such as regulatory, laboratory and practical issues from different perspectives, Volume II more specifically discusses medical aspects and the use of antimicrobials in cattle, pigs, poultry and horses, as well as pharmacokinetics and pharmacodynamics, two of the most important factors determining the success of treatment. In both volumes, each chapter confronts the reader with open questions to stimulate further discussions and future research on the topics covered.

This book examines the effect of whole-wheat bread on health, with evidence linking the consumption of whole-wheat products to a decrease in the relative risk of non-communicable diseases in comparison with products baked from refined flour. The authors focus on key areas such as milling and refining procedures, bakery products, and assessment of the present consumption of wheat products. They offer a detailed description of all available ingredients of wheat-kernel, with particular attention paid to the health benefits of wheat-kernel antioxidants and dietary fiber ingredients. Vitamins, glutathione, choline and betaine, carotenoids, sterols and stanols are covered, and the book concludes with a general overview of the effect of whole-wheat bread on colon activity and immune capacity. Methods of improving bread nutritional quality, and the potential for the upgrading of the nutritional qualities of whole-bread, are also discussed. Consumption of whole-wheat in Western societies, however, has either not increased or increased very slightly. The authors intend for this book to highlight the health benefits of whole-wheat bread and the factors that contribute to these benefits.

Referred to in the Bible, pictured on the wall-friezes of ancient Egyptian tombs, and a subject of fascination for generations of scientists, the tilapias (Cichlidae: Tilapiini) have featured in the diet and culture of humankind for thousands of years. The present century has seen their spread from Africa throughout the tropics and sub-tropics, largely for food and fisheries purposes. This book attempts to pull together our knowledge of this important group - their biology and fisheries and aquaculture - in a single volume, something that has not been done comprehensively for nearly two decades. A succession of chapters by acknowledged authorities covers evolution, phylogenetic relationships and biogeography, reproductive biology, mating systems and parental care, diet, feeding and digestive physiology, environmental physiology and energetics, the role of tilapias in ecosystems, population dynamics and management, genetics, seed production, nutrition, farming, economics and marketing. The book is aimed at biologists, fisheries scientists, aquaculturists, and all interested in aquatic ecology.

Toxins are virulence determinants that play an important role in microbial pathogenicity and/or evasion of the host immune response. This makes them ideal targets for the development of novel antimicrobial strategies. The potential applications of toxin research extend beyond simple combating microbial pathogens and include use as novel anti-cancer drugs and other front-line medicines and as tools in neurobiology. This book serves as an update on the most important recent advances in the genetics, cellular biology and practical applications of the most important bacterial toxins.

Microbial cell wall structures play a significant role in maintaining cells' shape, as protecting layers against harmful agents, in cell adhesion and in positive and negative biological activities with host cells. All prokaryotes, whether they are bacteria or archaea, rely on their surface polymers for these multiple functions. Their surfaces serve as the indispensable primary interfaces between the cell and its surroundings, often mediating or catalyzing important interactions.

"Prokaryotic Cell Wall Compounds" summarizes the current state of knowledge on the prokaryotic cell wall. Topics concerning bacterial and archaeal polymeric cell wall structures, biological activities, growth and inhibition, cell wall interactions and the applications of cell wall components, especially in the field of nanobiotechnology, are presented.

For a virus to invade a host cell it needs to penetrate the physical barrier imposed by the plasma membrane. Viruses have evolved specialized surface proteins to meet this challenge. These proteins facilitate delivery of the viral genetic information into the host cell by either fusing the viral envelope with a host cell membrane or by forming membrane pores. Membrane fusion and pore formation critically depend on the engagement of host cell receptors and receptor choice is a key determinant of viral tropism. The multi-faceted interplay between viral and cellular factors during virus entry is a fascinating field of study, which can provide important insight into viral pathogenesis and define new targets for intervention. This book provides a comprehensive overview of this exciting field of research.

During the last decade a wealth of new data has arisen from the use of new fluorescent labelling techniques and the sequencing of whole microbial genomes. One important conclusion from these data is that bacterial cells are much more structured than previously thought. The wall and the outer membrane contain topological domains, some proteins localize or move in specific patterns inside the cells, and some genes appear clustered in the chromosome and form conserved evolutionary units. Many of these structures are related to the cell cycle and to the process of cell morphogenesis, two processes that are themselves related to each other. From these observations the dcw gene cluster appears as a phylogenetic trait that is mainly conserved in bacilli. Molecules in Time and Space reviews the data on the formation of subcellular patterns or structures in bacteria, presents observations and hypotheses on the establishment and the maintenance of cell shape, and on the organization of genetic information in the chromosome.

PCR methods for the detection of microbial pathogens have made relatively little impact in diagnostic microbiology laboratories due to the common decision to use expensive commercially produced tests rather than the cheaper alternative of developing one's own tests or introducing tests developed by other workers. PCR Detection of Microbial Pathogens, Second Edition presents alternatives to commercially produced PCR methods to detect microbial pathogens. Although most of the chapters in this book are devoted to the detection of specific pathogens, the first chapters in this book should appeal to anyone working in this field regardless of their particular interests. Although PCR tests can often be made to work with relatively little effort, it is often unclear how efficient the PCR test is, how inhibitory the specimen containing the pathogen of interest is and how the test can be quality controlled. All of which are of great importance in developing tests for diagnostic use. These topics are covered in great depth at the beginning of the book. The main part of the book is devoted to describing methods for the detection of a wide range of pathogens and from widely different specimens and situations. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, PCR Detection of Microbial Pathogens, Second Edition serves microbiologists regardless of their particular interest because, when used together with the general principles, the sheer variety of procedures provided here enables the reader to design and introduce diagnostic tests in the laboratory with confidence.

The search for new producers of biologically active substances (BAS) against human and animal diseases continues to be an important task in biology and medicine. Experimental work must be carried out well in advance of need because it takes an average of ten years to develop a new medication, as well as additional time to put it on the market. Study of the Protozoa forms a special branch of biology - protozoology. The traditional fields of protozoology are taxonomy, phylogeny, morphology, cytology, evolution, ecology and host parasite-interactions. The Protozoa is the only taxon among the microscopic organisms, which has not been persistently studied as a source of BAS. This book then is the result of the research on the project: "Biologically active substances of the Mastigophora (Flagellates)." The research was carried out at the Laboratory of Antibiotics, Department of Microbiology, Biological Faculty of Moscow State University. Articles of other authors on the matter have been considered as the important part of this reference book. The goal of the reference book is to elucidate scientific approaches, which lead to obtaining biologically active substances from cultures of protozoa; the book reviews the historical background in connection with contemporary development of the field.
