An identification handbook containing descriptions of 974 species of non-gilled fungi in 277 genera and figures of 543 of them. There are two major keys to genera and a key to the species in each genus that contains more than one species. The fungi described and illustrated can nearly all be found in Great Britain. The book aims to stimulate interest in groups of fungi which have hitherto attracted relatively few workers. Resupinate fungi, club fungi, jelly fungi, brackets, earth stars, puffballs and so on are not difficult to identify with a little practice and many of them flourish and sporulate freely during the winter months and thus it is possible to study mycology all year round if all groups are studied. In this book measurements, except where otherwise stated, are in thousandths of a millimetre. Terms which may be unfamiliar are explained in the glossary and for quick reference genera in the two main sections are arranged in alphabetical order.
This book gathers a wealth of contributions on the virulence factors and pathogenic mechanism of Helicobacter pylori, prepared by leading international experts. In addition, it explores the epidemiology, diagnosis, treatment with drugs and probiotics, and prophylaxis by vaccination, reflecting the latest advances. H. pylori is a Gram negative microaerophilic bacterium that can produce various gastric diseases including gastritis, gastroduodenal ulceration, gastric cancer and gastric MALT lymphoma. Although efforts to combat H. pylori using a combination of proton pump inhibitor and several antimicrobial drugs have significantly decreased the burden of these gastric diseases, the microbial epidemiology and gastric pathogenesis following H. pylori infection are still not fully understood. Given its scope, the book offers a valuable resource not only for basic microbiologists, but also for researchers in the fields of pathology, biochemistry and genomics, as well as medical students/scientists.
Morphological, physiological and pathological evidence demonstrates that ner- vous and immune systems interact not only in maintaining brain homeostasis, but also in causing neurological diseases. The studyofthese interactions repre- sents the basis on which neuroimmunologyhas grown during the years. At pre- sent, several neurological diseases are recognized to be caused by a derange- ment of the immune system in either its regulatory or effector functions. The main scope ofthis book, to discuss how an unbalanced immune system maylead to immune-mediated neurological diseases, is achieved in three parts. The first part provides an overview on how the immune system works. This is propaedeutical to understanding interactions between the immune and ner- vous systems, which are discussed in the second part. The third part of the book focuses on one particular area of neuroimmunology, the immune disor- ders leading to the damage of central and peripheral myelin. Given the opportunity to review first the immune system in itself and then how it operates during immune-mediated demyelinating disorders, we have tried to provide the reader with a basis for clearly understanding how interac- tions between the immune and nervous systems can be protective or pathoge- nic. This knowledge is a prerequisite for a rationale immune intervention tar- geting these disorders.
This book discusses microbial diversity in various habitats and environments, its role in ecosystem maintenance, and its potential applications (e.g. biofertilizers, biocatalysts, antibiotics, other bioactive compounds, exopolysaccharides etc.). The respective chapters, all contributed by renowned experts, offer cutting-edge information in the fields of microbial ecology and biogeography. The book explains the reasons behind the occurrence of various biogeographies and highlights recent tools (e.g. metagenomics) that can aid in biogeography studies by providing information on nucleic acid sequence data, thereby directly identifying microorganisms in various habitats and environments. In turn, the book describes how human intervention results in depletion of biodiversity, and how numerous hotspots are now losing their endemic biodiversity, resulting in the loss of many ecologically important microorganisms. In closing, the book underscores the importance of microbial diversity for sustainable ecosystems.
The bacterial lipopolysaccharide also known as endotoxin is exhaustively covered in the present work. Central emphasis is placed upon the fine chemical structure of the lipopolysaccharide and its significance for understanding their activity and function. In particular, the role it plays in the interaction of bacteria with other biological systems is examined. New aspects of their physicochemical biology are introduced and updates to the current knowledge concerning the lipopolysaccharide are provided. This important class of biomolecules has recently attracted the attention of many investigators, in particular for understanding its involvement in innate immunity, toll-like receptor recognition and intracellular signaling.
In this book, a panel of experts discuss the molecular biology of micro-organisms involved in the two major dental diseases: caries and periodontal disease. Research has focused on factors which might modulate the interaction between the resident oral bacteria and the host. Chapters deal with the interactions of oral micro-organisms with one another and with the host; the innate defense mechanisms of the host; and the development of vaccines against oral diseases. Topics include oral microbial taxonomy, identification and typing, applied genomics, horizontal gene transfer, cell-cell communication, cariogenic bacteria, aggregatibacter actinomycetemcomitans, porphyromonas gingivalis, treponema denticola, host-pathogen interaction, host defense mechanisms, and vaccination against oral infections. Essential reading for students and researchers in the field of oral biology and oral microbiology and a recommended book for all microbiology laboratories.
It is a truism among biologists that an organism's phenotype is the product of both its genotype and its environment. An organism's genotype contains the total informational potential of the individual, while its environment shapes the expression of the ge- type, influences the rate of mutation and occurrence of modifications, and ultimately determines the likelihood that the genotype (or fractions thereof) will survive into the next generation. In the relationship between host and pathogen, therefore, each forms a part of the environment of the other, mutually influencing the biology of both partners on scales ranging from the life history of individuals to the fate of populations or entire species. Molecular biologists working on problems in pathogenesis generally think of the host organism as the pathogen's environment and perhaps occasionally consider the pathogen as part of the host's environment. However, because "environment" can be defined at many scales, so, too, can phenotypes: if a pathogen, as a species, is c- sidered to exist in a host, as a species, then among its phenotypes is the nature of the pandemic disease it can cause within the host community. The contributors to the proceedings of this NATO Advanced Research Workshop have treated the interplay of environment and genotype in the host-pathogen relationship and its relationship to the problem of emerging infectious disease at both the macroscopic and microscopic/ molecular levels along this continuum of scale (with some human history thrown in at times for good measure).
This book brings together and updates the latest information on the diversity of yeasts, their molecular features and their applications in the welfare of mankind. Yeasts are eukaryotic microfungi widely found in natural environments, including those with extreme conditions such as low temperatures, low oxygen levels and low water availability. To date, approximately 2,000 of the estimated 30,000 to 45,000 species of yeast on Earth, belonging to around 200 genera have been described. Although there are a few that are opportunistic human and animal pathogens, the vast majority of yeasts are beneficial, playing an important role in the food chain and in the carbon, nitrogen and sulphur cycles. In addition, yeasts such as Saccharomyces cerevisiae, Hansenula polymorpha and Pichia pastoris are used in expressing foreign genes to produce proteins of pharmaceutical interest. A landmark in biotechnology was reached in 1996 with the completion of sequencing of the entire S. cerevisiae genome, and it has now become a central player in the development of an entirely new approach to biological research and synthetic biology. The sequencing of genomes of several yeasts including Schizosaccharomyces pombe, Candida albicans and Cryptococcus neofromans has also recently been completed.
The complexity of the microbial population of the animal gastro-intestinal trac has been recognised long ago. However, thus far, investigations have been limited to a few major groups, considered to be dominating, and pathogens that are detrimental and may case diseases and concomitant financial losses in the production animal. Thanks to the latest developments, including improved micriological detection and sampling techniques, and the application of molecular tools to monitor the presence of specific strains in the intestine, our knowlede has increased rapidly in recent years. In addition, new approaches towards improving and/or stabilising animal health, are addressed, with special emphasis on probiotics, and also with regard to the use selected bacterial strains as vehicles for delivery of pharmaceutically active compounds to the muscosa. The book is unique in several respects, not only by its coverage of an extremely wide area in animal gut microbiology, but also by the fact that production animals such as fish and reindeer are included. Scope and treatment of the subject matter and the kind of information that can be found in the volume: Colonisation and development (succession), and mucosal surface composition of the normal microbial population flora in the healthy animal are addressed, whilst estensive information is given on diverse and dominating bacterial populations of different animal types. Reference is also made to those microbial groups considered to be of special benefit to the health and immune protection of the (young) animal bacteria. The development and application of models of the Gastro-Intestinal tract provides a solid basis for studying gut microbial interactions, whilst molecular approaches and the us of molecular tools to monitor the presence of specific strains in the intestine is treated in a comprehensive manner. Wide coverage of different animal types and their gut microbial ecology Extensive and partly new information on the major microbial groups associated with the animal gastro-intestinal tract The book is unique and partly new information and up-to-date information proved in the chapters as a whole
Helminths include one of the most diverse and geographically widespread groups of parasites which infect humans and animals. About 100 species have been reported from humans, usually producing asymptomatic infection or mild symptoms. However, about 20 species are of public health importance causing severe or even fatal infections. In many parts of Africa parasitic helminths are responsible for enormous economic losses, hampering rural development programmes and reducing the pace of economic growth. Many parasitic helminths are either zoonoses (diseases naturally transmitted between vertebrate animals and man) or have evolved from animal parasites. The modification of the environment through wars, famine and the ever expanding and increasingly mobile human population brings people into close contact with new environments and wildlife species which makes the study and control of zoonoses of special interest and complexity. In Africa, the transmission of helminth parasites is highly influenced by the ever changing social and cultural differences between diverse groups of peoples and their interaction with wild and domestic animals. It is not surprising, therefore, that approaches to the study and control of parasitic zoonoses require intersectoral cooperation between physicians, veterinarians, parasitologists, zoologists, demographers, anthropologists, engineers and economists to provide the breadth of knowledge and expertise required to develop our understanding of these diseases and to devise methods for their control. This book provides a selective compilation of parasitic helminths, many of which are zoonoses which create important economic and public health problems in Africa.
In ancient times foods fermented with lactic acid bacteria already constituted an important part of the human diet. From then on, lactic acid bacteria have played an essential role in the preservation of food raw materials and have contributed to the nutritional, organoleptic and health properties of human food products and animal feed. The important function that lactic acid bacteria still have in the production of foods all over the world has resulted in a growing scientific interest in these micro-organisms by academic research groups as well as by industry. During the last 15 years, this research has been stimulated by major internationally coordinated funding efforts that have resulted in a variety of important scientific breakthroughs and have led to new applications. Written by international experts in the field, this issue of Antonie van Leeuwenhoek documents these developments with respect to genetics, metabolism and the application of lactic acid bacteria for industrial and potential medical applications. In this book the first complete genome of a lactic acid bacterium is presented. The book will serve as a reference source and also as an indispensable source of information for further development and exploration of the field.
Plants produce more than 30,000 types of chemicals, including pharmaceuticals, pigments and other fine chemicals, which is four times more than those obtain ed from microbes. Plant cell culture has been receiving great attention as an alternative for the production of valuable plant derived secondary metabolites, since it has many advantages over whole plant cultivation. However, much more research is required to enhance the culture productivity and reduce the pro cessing costs, which is the key to the commercialization of plant cell culture pro cesses. The recent achievements in related biochemical engineering studies are reviewed in Chapter 1. The effect of gaseous compounds on plant cell behavior has been little studied, and Chapter 2 focuses on these gas concentration effects (including oxygen, carbon dioxide, ethylene and others, such as volatile hor mones like methyl jasmonate) on secondary metabolite production by plant cell cultures. Two metabolites of current interest, i. e. , the antimalarial artemisinin (known as "qing hao su" in China) that is produced by Artemisia annua (sweet wormwood) and taxanes used for anticancer therapy that are produced by species of Taxus, are taken as examples. Bioprocess integration is another hot topic in plant cell culture technology. Because most of the plant secondary meta bolites are toxic to the cells at high concentrations during the culture, removal of the product in situ during the culture can lead to the enhanced productivity. Various integrated bioprocessing techniques are discussed in Chapter 3.
The history of research on hog cholera (HC)/classical swine fever (CSF) can be roughly divided into three phases which are characterized by the methods available at the time for demonstrati ng the causati ve agent. Phase covered the period before the viral etiology of HC was discovered by de Schweinitz and Dorset (1904)*. Thereafter (Phase II) the detection of HC virus (HCV) was accomplished by laborious, time-consuming and costly pig inoculation experiments. This explains the extensive search for methods not only for detection but also for accurate infectivity titration as well as for applicable serological techniques to solve urgent problems concerning the pathogenesis, diagnosis, epidemiology and prophylaxis of HC. It was not before the late fifties that HC research entered Phase III when fluorescent antibody techniques offered not only the means for detection and titration of HCV in porcine cell cultures but also for more intensive research on hog cholera and its virus. And yet, there are a number of questions to be answered, e. g. on the genetic and antigenic relation of HCV to bovine viral diarrhea (BVD) virus. There are indications that Phase IV of HC research will bear the stamp of biotechnology. In view of this development it appears appropriate to give an up-dating and summarizing account of HC/CSF including comparative aspects of infections caused by structurally related viruses. The editIon of the present volume would have been impossible without the cooperation of several known scientists who instantly agreed when asked for contribution.
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 Growth Responses " describes the application of various bacteria in plant growth promotion and protection, including symbiotic, free living, rhizospheric, endophytic, methylotrophic, diazotrophic and filamentous species.
In the first edition of Calcium Signaling Protocols I began by writing "The regula- 2+ tion of intracellular Ca is a common theme presented in many papers over the last 20 2+ or so years and the description of the Ca -sensitive indicator dye fura-2 in 1985 resulted in a massive increase in these types of studies. " This statement is as true in 2005 as it was in 1999, but 20 or so years is now 30 years! There has been some reorganization of the volume such that there are now 22 ch- ters including five new ones, all written by experts in their field. These new chapters 2+ include use of the FlexStation and electrophysiological measurement of Ca channel activity. The book is broken into six parts. Part I is a general coverage of basic theory and the simplest use of fluorescent indicators. Part II covers specialist measurement 2+ systems and Part III covers measurement of Ca channel activity. Assessment of 2+ release of stored Ca is covered in some detail in Part IV, with Parts V and VI cover- 2+ ing specialist measurement techniques and Ca -sensitive targets. Putting a book like this together, even as a second edition, takes time and I am, again, indebted to the individual authors for their help and patience. I am also very grateful to Professor John M. Walker, the series editor, for his continued help and advice over the course of this project.
From Fossils to Astrobiology reviews developments in paleontology and geobiology that relate to the rapidly-developing field of Astrobiology, the study of life in the Universe. Many traditional areas of scientific study, including astronomy, chemistry and planetary science, contribute to Astrobiology, but the study of the record of life on planet Earth is critical in guiding investigations in the rest of the cosmos. In this varied book, expert scientists from 15 countries present peer-reviewed, stimulating reviews of paleontological and astrobiological studies. The overviews of established and emerging techniques for studying modern and ancient microorganisms on Earth and beyond, will be valuable guides to evaluating biosignatures which could be found in the extraterrestrial surface or subsurface within the Solar System and beyond. This volume also provides discussion on the controversial reports of "nanobacteria" in the Martian meteorite ALH84001. It is a unique volume among Astrobiology monographs in focusing on fossil evidence from the geological record and will be valuable to students and researchers alike.
The articles in this volume provide a comprehensive overview of our current understanding of the roles played by cellular factors in the early steps of retroviral replication. A better understanding of these functions will provide critical new insights into retrovirus-host cell interactions and is likely to prove useful for the future development of effective antiretroviral therapies.
Grain legume crops, e.g. common bean (Phaseolus vulgaris L.), and soyabeans (Glycine max L.) are amongst the main sources of protein in Africa, Asia and Latin America. Their high protein content derive from their ability, in symbiosis with Rhizobium bacteria, to fix atmospheric nitrogen. Incorporating contributions from molecular biologists, microbiologists, plant breeders and soil scientists, this volume reports the results of an FAO/IAEA Co-ordinated Research Programme (1992-1996), whose main objective was to develop molecular biological methods to study rhizobial ecology. Use of better tracking methods will help enhance biological nitrogen fixation and thus grain legume yields, while reducing their reliance on soil- and/or fertilizer-nitrogen. This volume will be invaluable to scientists working on biological nitrogen fixation, soil microbial ecology and legume production.
Nematodes are one of the most abundant groups of invertebrates on the face of the earth. Their numbers are estimated to range from 1000 per cm2 in the sand-covered hydrogen sulphide black zone beneath the ocean floors to 1.2 billion in a single hectare of soil. Estimates for their species diversity range from 100 000 to 10 million. The past history of nematodes is a mystery, since very few fossils have been discovered. This book establishes a solid base in palaeonematology with descriptions of 66 new fossil species and accounts of all previous fossil and subfossil nematodes from sedimentary deposits, coprolites, amber and mummies. It shows how nematode fossils can be used to establish lineages at various locations and time periods in the earth s history and when nematodes entered into symbiotic and parasitic associations with plants and animals.
This title discusses various effects of heavy metal exposure to legumes as well as the bioremediation potential of rhizosphere microbes. Availability of heavy metals, their uptake and the effects of metals on various signaling pathways within legumes are presented. Furthermore, the effects of heavy metals to nitrogen fixing microorganisms and how microsymbionts can overcome metal stress is presented in detail. The role of nitrogen fixers in decontamination of heavy metal toxicity, mycoremediation of metal contaminated soils, microbially mediated transformation of heavy metals and action of plant growth promoting rhizobacteria and nitrogen fixers together in detoxifying heavy metals are broadly explained. This volume is a useful tool for scientists, policy makers and progressive legume growers intending to develop safe and healthy legumes for future generations.
The microbiology of drinking water remains an important worldwide concern despite modem progress in science and engineering. Countries that are more technologically advanced have experienced a significant reduction in water borne morbidity within the last 100 years: This reduction has been achieved through the application of effective technologies for the treatment, disinfec tion, and distribution of potable water. However, morbidity resulting from the ingestion of contaminated water persists globally, and the available ep idemiological evidence (Waterborne Diseases in the United States, G. F. Craun, ed. , 1986, CRC Press) demonstrates a dramatic increase in the number of waterborne outbreaks and individual cases within the United States since the mid-1960s. In addition, it should also be noted that the incidence of water borne outbreaks of unknown etiology and those caused by "new" pathogens, such as Campylobaeter sp. , is also increasing in the United States. Although it might be debated whether these increases are real or an artifact resulting from more efficient reporting, it is clear that waterborne morbidity cannot be ignored in the industrialized world. More significantly, it represents one of the most important causes of illness within developing countries. Approxi mately one-half the world's population experiences diseases that are the direct consequence of drinking polluted water. Such illnesses are the primary cause of infant mortality in many Third World countries.

Timely and thorough, this volume will become an essential reference for anyone using baculoviruses and insect cell culture.
This book provides an up-to-date overview of the various wood and tree fungi that damage trees, lumber, and timber. Special focus is given to identification, prevention, and remediation techniques, and the book bridges the gap between research and application. It covers the fundamentals of cytology and morphology. There is a more practical section describing damage by viruses and bacteria on trees. The habitats of wood fungi are described as well as tree care. Important tree pathogens and wood decay fungi are characterized for prevention and identification. The final section focuses on the positive effects of wood-inhabiting microorganisms.
Dr. Hilary Koprowski is the pioneer of live polio vaccine, the first researcher to advance the diagnostic and therapeutic use of monoclonal antibodies, and the developer of the "gold standard" rabies vaccine. A world-reknowned maverick in biomedical research, Koprowski's research methods were often considered controversial and even radical. Nonetheless, he acquired key positions in many research organizations, such as the Rockefeller Foundation, Lederle Labs, and Wistar Institute, initiating landmark studies from cancer research to multiple sclerosis. One of his crowning achievements, the successful crusade for monoclonal antibodies, resulted in his founding of Centocor, a forerunner in the corporate world of biomedicine. This account of Koprowski's life history is a mixture of personal interviews, anecdotes, and legends of the art and science behind the man. |
