Genetics has transformed plant pathology on two occasions: first when Mendelian genetics enabled the discovery that disease resistance was a heritable trait in plants, and secondly when Flor proposed the "gene-for-gene" hypothesis to explain his observations of plant-parasite interactions, based on his work on flax rust in North Dakota starting in the 1930s. Our knowledge of the genetics of disease resistance and host-pathogen coevolution is now entering a new phase as a result of the cloning of the first resistance genes. This book provides a broad review of recent developments in this important and expanding subject. Both agricultural and natural host-pathogen situations are addressed. While most of the book focuses on plant pathology, in the usual sense of the term embracing fungal, bacterial and viral pathogens, there is also consideration of parasitic plants and a chapter demonstrating lessons to be learnt from the mammalian immune system. Three overall themes are addressed: genetic analyses and utilization of resistance; population genetics; and cell biology and molecular genetics. Chapters are based on papers presented at the British Society for Plant Pathology Presidential meeting held in December 1995, but all have been revised and updated to mid-1996. Written by leading authorities from North America, Europe and Australia, the book represents an essential update for workers in plant genetics, breeding, biotechnology and pathology.

Biology of Ticks is the most comprehensive work on tick biology and tick-borne diseases. This second edition is a multi-authored work, featuring the research and analyses of renowned experts across the globe. Spanning two volumes, the book examines the systematics, biology, structure, ecological adaptations, evolution, genomics and the molecular processes that underpin the growth, development and survival of these important disease-transmitting parasites. Also discussed is the remarkable array of diseases transmitted (or caused) by ticks, as well as modern methods for their control. This book should serve as a modern reference for students, scientists, physicians, veterinarians and other specialists. Volume I covers the biology of the tick and features chapters on tick systematics, tick life cycles, external and internal anatomy, and others dedicated to specific organ systems, specifically, the tick integument, mouthparts and digestive system, salivary glands, waste removal, salivary glands, respiratory system, circulatory system and hemolymph, fat body, the nervous and sensory systems and reproductive systems. Volume II includes chapters on the ecology of non-nidicolous and nidicolous ticks, genetics and genomics (including the genome of the Lyme disease vector Ixodes scapularis) and immunity, including host immune responses to tick feeding and tick-host interactions, as well as the tick's innate immune system that prevents and/or controls microbial infections. Six chapters cover in depth the many diseases caused by the major tick-borne pathogens, including tick-borne protozoa, viruses, rickettsiae of all types, other types of bacteria (e.g., the Lyme disease agent) and diseases related to tick paralytic agents and toxins. The remaining chapters are devoted to tick control using vaccines, acaricides, repellents, biocontrol, and, finally, techniques for breeding ticks in order to develop tick colonies for scientific study.

"Perspectives in Inflammation Biology" outlines detailed studies using preclinical murine models in Inflammation. The book is meant for academicians, industry persons, research scholars and students alike. The detailed perspective for a beginner and the exhaustive methodologies and analyses outlined, for the veteran researcher, makes this book a unique link between someone who is thinking of embarking on a study of inflammation and one who is delving deep into this area of specialization. The book deals with asthma and allergy as specific disease areas of inflammation of the lung, aseptic peritonitis as a disease of systemic inflammation and details how each role player in its pathophysiology has a unique niche of activity. Data acquisition, sequentiality and analyses in context demonstrate how each role player is validated systematically to become a target for drug discovery. Methods and models used in the course of my work and their relevance will demonstrate to the researcher how a study can be developed from an idea. Further into a researcher's ongoing work, this book is meant to stimulate new questions and pave ways for better dissection of a phenomenon. The highlights of this book are the detailed tables tabulating sub species of immune cells, their inflammatory recruitment indices, their translation into tissue-to-tissue traffic of the inflammatory stimulus and the delicate interplay of resident structural cells, cells recruited from circulation, their feedback poiesis in bone marrow, their instruction in the lymphoid organs and tissues as well as the non-cellular mediators synthesized from corresponding genetic instruction. The book shall definitely help students and researchers how a disease can be simplified from its complex ramifications and network of implications and put back into perspective and the whole thing falls into place without an intimate understanding of the mechanism and the compelling circumstances that causes a disease, a drug hunter cannot hope to begin her quest. To find the "Achilles' heel" and effectively neutralize the enemy!

This book is the first major synthesis of theory and empirical knowledge regarding the ecology and epidemiology of infectious diseases in natural, unmanaged, animal and plant populations. Throughout the book, the contributors develop a dialogue between the patterns observed in empirical studies of disease in natural populations and the mathematical models used to dissect and examine the observed epidemiological patterns. The book is divided into a number of reviews and group reports by experts in various fields. Two sections synthesize important issues relating to the dynamics of microparasites and macroparasites, while the others discuss spatial patterns in disease dynamics and the evolutionary biology of parasites, pathogens and their hosts. This book will be of use to graduate students and specialists in mathematical biology and epidemiology.

This book presents results obtained from the whole mount preparations, radiological, and histological studies of 60 pu/pu and pu/+ mice from late embryo until 3 months of age. Most mice were in the embryo to 6 week age group where vertebral developmental changes are most marked. Although vertebral abnormalities have been identified as due to mutations in the delta-like 3 (Dll3) gene, it is evident that each mouse has differing structural abnormalities. The disorder is analogous to human congenital scoliosis, a common variant of which is spondylocostal dysplasia. The histological studies presented in this book include plastic embedded sections which allow for high level resolution not only of vertebrae, intervertebral discs, and ribs but also of associated spinal cord, nerve roots and ganglia. In addition an overview of embryo and neonatal development in mouse, chick and human vertebrae is provided to better assess how and where deviant pathoanatomy occurs. The book discusses the possible variables involved in creating final deformity beyond the gene abnormality itself.

Metastatic dissemination of cancer is a main cause of cancer related deaths, therefore biological mechanisms implicated in metastatic process presents an essential object of cancer research. This research requires creation and utilization of adequate laboratory models. The book describes main approaches to model processes of metastatic cancer dissemination and metastases development. The book is structured in according with various metastatic pathways reflecting molecular specificity of metastatic process as well as anatomical specificity of aria of dissemination. Each chapter is introduced by short discussion of clinical aspects of certain metastatic pathway. Especial attention is paid for methods of visualization, quantification and analysis of the modeled metastases. Additional chapter is devoted to methods of mathematic modeling of tumor spread. The data presented in the book may be helpful for cancer researchers and oncologists.

Undoubtedly, Drosophila melanogaster, fruit fly, has proved to be one of the most popular invertebrate model organisms, and the work horse for modern day biologists. Drosophila, a highly versatile model with a genetic legacy of more than a century, provides powerful genetic, cellular, biochemical and molecular biology tools to address many questions extending from basic biology to human diseases. One of the most important questions in biology focuses on how does a multi-cellular organism develop from a single-celled embryo. The discovery of the genes responsible for pattern formation has helped refine this question, and led to other questions, such as the role of various genetics and cell biological pathways in regulating the crucial process of pattern formation and growth during organogenesis. Drosophila eye model has been extensively used to study molecular genetic mechanisms involved in patterning and growth. Since the genetic machinery involved in the Drosophila eye is similar to humans, it has been used to model human diseases and homology to eyes in other taxa. This book will discuss molecular genetic mechanisms of pattern formation, mutations in axial patterning, Genetic regulation of growth in Drosophila eye, and more. There have been no titles in the past ten years covering this topic, thus an update is urgently needed.

Rabies is the deadliest zoonotic disease that threatens humans and animals on all continents except Antarctica. Asia and Africa are worst affected as more than 95 per cent of rabies associated human deaths occur in these regions. India alone bears about 36 per cent of the global human rabies burden. Dogs are the main transmitters of rabies that potentially threaten over 3 billion people in Asia and Africa. Many developed nations have been able to successfully control dog rabies but continue to face the risk from wildlife including bats. Bat rabies is responsible for most human rabies deaths in the United States of America and Canada but has emerged as a public health threat in Australia, Latin America and Western Europe as well. Despite being vaccine preventable, rabies continues to haunt the mankind. Poor resources is a major constraint but the factors like low priority attributed to rabies, misconceptions in the community about the disease and unsystematic approach for its prevention and control are also responsible for the grim situation. Targets have been set for elimination of human and dog rabies in all Latin American countries by 2015 and of human rabies transmitted by dogs in South-East Asia by 2020. However, the myths prevailing among the people together with inadequate knowledge of the health professionals, veterinarians, and the civic body staff about the rabies prevention and control strategies might make the task very difficult. This book comprising eight chapters elaborates the causation of rabies in man and animals, its global epidemiology, risk analysis and effective strategies for the management of exposures. Proven methods of rabies prevention and control have been discussed in length along with the challenges and ways to overcome the constraints through intersectoral coordination. The inclusion of 200 frequently asked questions is a unique feature of the book which may help not only the common people and pet lovers in clearing their doubts about rabies in man and animals also be equally instrumental in updating the knowledge and skills of the public health personnel, veterinarians and other professionals. Apt illustrations and simple language make the contents of the book easily comprehensible and a reading pleasure.

This book, written by experienced geneticists, covers topics ranging from the natural history of the mouse species, its handling and reproduction in the laboratory, and its classical genetics and cytogenetics, to modern issues including the analysis of the transcriptome, the parental imprinting and X-chromosome inactivation. The strategies for creating all sorts of mutations, either by genetic engineering or by using mutagens, are also reviewed and discussed in detail. Finally, a last chapter outlines the methodology used for the analysis of complex or quantitative traits. The authors also discuss the importance of accurate phenotyping, which is now performed in the mouse clinics established worldwide and identify the limits of the mouse model, which under certain circumstances can fail to present the phenotype expected from the cognate condition in the human model. For each chapter an up-to-date list of pertinent references is provided. In short, this book offers an essential resource for all scientists who use or plan to use mice in their research.

This volume provides a transdisciplinary and translational review of many of the leading murine models used to study the mechanisms, mediators and biomarkers linking energy balance to cancer. It provides a review of murine models that should be of interest to basic, clinical and applied research investigators as well as nutrition scientists and students that work in cancer prevention, cancer control and treatment. The worldwide obesity pandemic has been extensively studied by epidemiologic and observational studies and even, in some cases, by randomized controlled trials. However, the development and control of obesity, its comorbidities and its impact on cancer usually occurs over such long periods that it is difficult, if not impossible to conduct randomized controlled trials in humans to investigate environmental contributions to obesity, energy balance and their impact on cancer. In contrast, model organisms, especially mice and rats, provide valuable assets for performing these studies under rigorously controlled conditions and in sufficient numbers to provide statistically significant results. In this volume, many of the leading and new murine models used to study the mechanisms and mediators linking cancer with obesity, sleep, exercise, their modification by environment and how they may continue to be used to further elucidate these relations as well as to explore preclinical aspects of prevention and/or therapeutic intervention are considered. This volume provides an important compilation and analysis of major experimental systems and principles for further preclinical research with translational impact on energy balance and cancer.

Mechanisms controlling aggressive behavior started to be identified from late 20's of the 20th century and subsequent research described such mechanisms in great detail. While the findings are of great relevance for the understanding of aggression per se, they provide limited insights into the mechanisms of abnormal aggression i.e. those mechanisms that underlie aggression-related psychopathologies. While basic phenomena and mechanism of aggression are presented, this book is the first that comprehensively describes ultimate and proximate mechanisms that transform normal (laboratory animals) or tolerable (humans) manifestations of aggressiveness into abnormal patterns in laboratory animals and aggression-related psychopathologies in humans. This book is written for behavioral neurobiologists and neuroscientists, interested in emotional control in general and aggression research in particular. The book will also offer important information to neurologists and psychiatrists dealing with aggressive behavior in the clinic and ultimately, may provide means to understand and on the long run to discover novel approaches to the treatment of abnormal human aggression.

Using rodent models, this volume explores the basic neurobiology of the relationship among chronic pain, opioid pharmacology, and addiction.

Ocular toxicity is routinely assessed in toxicology studies conducted for regulatory purposes. Ocular anatomy and physiology and the assessment of ocular toxicity itself can be challenging to scientists involved in the safety assessment of pharmaceuticals, pesticides and other agents. Anatomical and physiological differences between species can impact the nature of ocular effects observed following intended or unintended exposure of ocular tissues to xenobiotics. Ocular Toxicity in Laboratory Animals provides a concise reference addressing ocular anatomy and physiology across species that will enhance the design and interpretation of toxicology studies conducted for regulatory purposes. The book provides an overview of routine and advanced techniques that are used to assess ocular toxicity including slit lamp biomicroscopy, indirect ophthalmoscopy, electrophysiology and imaging methods for the anterior and posterior segments of the eye. Additionally, the book defines the regulatory expectations for pharmaceuticals intended to treat ocular diseases and for other non-pharmaceutical regulated chemicals. With contributions from experts in the field, Ocular Toxicity in Laboratory Animals is an authoritative, accessible guide for toxicologists and other scientists involved in conducting toxicology studies for regulatory purposes and/or reviewing data from such studies.

Nuclear magnetic resonance imaging represents a technique that is indispensable in every day biomedical diagnostics. Thanks to the numerous ways to manipulate and detect an NMR signal, it is possible to obtain a variety of information with excellent spatial and temporal resolution. Today's MRI techniques go far beyond the illustration of pure anatomical structures and include the revealing of processes down to the molecular level. The number of small animal imaging centers relying on MRI as a key method for preclinical research to understand diseases and to test for novel treatments is growing rapidly. In Vivo NMR Imaging: Methods and Protocols is written as an experimental laboratory text to provide a descriptive approach of the various applications of magnetic resonance imaging and its underlying principles. Starting from a compact introduction of basic NMR physics and image encoding techniques suitable for a broad audience in the life sciences, the concept focuses on addressing the many ways of generating contrast in MR images. The authors cover an interdisciplinary range of problems to be addressed by this non-invasive modality, including study protocols for addressing morphological, physiological, functional, and biochemical aspects of various tissues in living organisms. Information about practical aspects of designing experimental studies that follow the special conditions for micro imaging setups are also provided. Written in the successful Methods in Molecular Biology (TM) series format, In Vivo NMR Imaging: Methods and Protocols aims to be an experimental compendium of modern in vivo MR imaging with special focus on recent developments in molecular imaging and new protocols for imaging metabolism and molecular markers.

The ovary is a suitable organ for studying the processes of cell death. Cell death was first described in the rabbit ovary (Graaffian follicles), the phenomenon being called 'chromatolysis'. To date, it is recognized that various forms of cell death (programmed cell death, apoptosis and autophagy) are essential components of ovarian development and function. Programmed cell death is responsable for the ovarian endowment of primordial follicles around birth; in the prepuberal and adult period, apoptosis is a basic mechanism by which oocytes are eliminated by cancer therapies and environmental toxicants; in the ovarian cycle, follicular atresia and luteal regression involve follicular cell apoptosis. Finally, abnormalities in cell death processes may lead to ovarian disease such as cancer and chemoresistance. In this book, after an introductory description of various forms of cell death and of the ovary development and function in mammals, the processes of cell death in ovarian somatic cells and oocytes are described at cytological, physiological and molecular levels and analyzed in the embryonic, prepuberal and adult ovary. A complex array of molecular pathways triggered by extrinsic and intrinsic signals able tor induce or suppress cell death in the same cell, according to cell type and ovary developmental stage, emerges. Physiological interactions with the axis hypothalamus-hypophysis as well as ovarian internal functional signal are also critically reviewed to explain the abortive development of follicles before the beginning of the ovarian cycle. The book conveys information useful to the updating of biologists and physicians who are interested to the ovary biology and functions. Hopefully it should provide also clues for stimulating novel experiments in the study of cell death in the mammalian ovary still at an early stage.

Immunity studies in sharks over the past three decades have produced some remarkable discoveries. If one message rings true, it is that alternative animal model systems, such as sharks and their relatives, have contributed very substantially to a better understanding of the development evolution of our own immune system. Immunobiology of the Shark describes the cellular, genetic, and molecular specifics of immune systems in sharks. Diverse approaches were employed to study the immunobiology of the shark from basic microscopic observations to detailed genome annotation. The book also raises a series of fascinating questions, which can be addressed experimentally using today's technology. This book will be a valuable resource for mainstream immunologists, comparative immunologists, geneticists, ecologists, evolutionary biologists, and investigators engaged in shark research. The book also aims to illustrate the magnificence of these animals as model systems and underscores the importance of their study to further understand their complex, and often enigmatic, biology.

This book describes in detail various aspects of fluoride toxicity in animals. Animals, like human beings, suffer from the toxic effects of excess fluoride intake. They show pathological changes in their teeth and bone, together with a marked reduction in appetite, productive and reproductive potentials, which can result in severe economic losses in the dairy industry. Laboratory and wild animals also suffer from this ailment. Animal suffering and economic losses alike can be minimized through early diagnosis of the problem and by adopting suitable preventive and therapeutic measures. The book details the susceptibility of different animal species, important sources of toxicity, clinical signs and symptoms, pathophysiology, diagnostic methods, preventive and therapeutic approaches. It offers a valuable resource for scientists working in the fields of toxicology, veterinary science, animal nutrition, and environmental science, as well as for public health workers, animal welfare activists, public health veterinarians, field veterinarians, medical professionals and all others interested in the subject.

Cell culture based research is important for our understanding of biological processes at the cellular and molecular level. Using this approach, the previous decades have produced a wealth of mechanistic information in all areas of biomedical research. Such in vitro research, however, lacks the complexity of in vivo investigations, where many different cell types interact with each other in a normal, three-dimensional environment, with normal levels of cytokines and growth factors. Furthermore, complex human diseases, such as cancer, diabetes or chronic inflammation, can only be modeled in vivo. Due to its small size, its short reproduction time, and the possibility to introduce specific gene mutations, the mouse has become the favourite mammalian model organism to study in vivo function of genes during development and in disease. This book combines review articles on selected subjects presented at the symposium "Mouse as a Model Organism - From Animals to Cells", held in Rovaniemi, Finland, 2009. Among other topics, high-throughput phenotyping of mouse mutants, mouse phenotypes dependent on nature and nuture, and a spectrum of in vivo, ex vivo and in vitro methods to study cancer in mice are described. This book will give an excellent introduction to scientists interested in the use of mice as a model to understand complex biological questions in the post-genomic era. It will highlight the possibilities, but also discuss the current problems and shortcomings, to give a realistic view of the current state-of-art in this fascinating field of biomedical research.

genic constructs. Five articles are devoted to this topic ranging from the B-cell function in transgenic animals to the various effects on diabetes complications. The section on NIDDM, comprising of 10 articles, deals both with new and existing models, their particular widely varying pathogenesis, genetic character- istics and complications. The animals reviewed include: spontaneously diabetic OLETF rats, Chinese hamsters, Goto-Kakizaki rats, db/db mice, rhesus monkeys, dogs and an article demonstrating the genetic link between the Zucker fa/fa and corpulent cp/cp obese interstrains. We wish to welcome the new members to our Editorial Board, Dr. Hubert Kolb from Dusseldorf, Dr. Alex Rabinovitch from Edmonton, Dr. Takayoshi Toyota from Sendai and Dr. Soroku Yagihashi from Hirosaki. At the same time we would like to thank Dr. Douglas L. Coleman from Bar Harbor and Dr. George Eisenbarth from Denver for their editorial contribution to the previous LAD Vol- umes who have retired from the Editorial Board. With great sadness we have to mention Dr. Otho Michaelis IV from Beltsville, MD who suddenly passed away this year. Otho, or Mike as he was called by friends, made a significant contribution in developing and metabolically defin- ing several strains of corpulent cp rats and was extremely helpful in the editor- ial work of the LAD series. His contribution will remain in a lasting memory of all researchers of animal diabetes.

Is it possible to omit parasites when studying free-living organisms? The answer is clearly no! Parasites have evolved independently in numerous animal lineages, and now make up a considerable proportion of the biodiversity of life. Ecologists, epidemiologists, conservationists and evolutionary biologists are increasingly aware of the universal significance of parasites to the study of ecology and evolution where they have become a powerful model system. This book provides a summary of the issues involved as well as an overview of the possibilities offered by this research topic including the practical applications for disease prevention. It uses well-documented case-studies across a range of scales to illustrate the main trends and prospects in this area, outlining areas for future research.
Ecology and Evolution of Parasitism is the first book to provide a broad synthesis of both the roles and consequences of pathogens on the ecology and evolution of free living systems. It focuses on hosts rather than the parasites themselves, integrating those aspects related to the ecology and the evolution of free-living species (sexual selection, behaviour, life history traits, regulation of populations etc.). The book includes examples across a range of scales from individuals to populations, communities and ecosystems.

The international advanced research workshop funded by NATO and entitled "impact of pollutions on animal and animal products" was organized at Almaty (Kazakhstan) on 27-30 September 2007. Thirty-one scientists from 12 countries (Kazakhstan, Kirgizstan, Azerbaijan, Ukraine, Russia, France, Great Britain, Italy, Belgium, Romania and Morocco) presented conferences at this meeting to share their experience and results. The programme included three main aspects: (i) generality on the pollution situation in Central Asia and former Soviet Union republics, (ii) the pollution area and pollution origin in Central Asia and Western countries in relation with animal health, and (iii) the relationships between soil contamination, plant contamination and animal products status. The present workshop contributed highly to the exchange between scientists giving the opportunity for researchers from Central Asia to access to new scientific approaches and methodologies, and for European scientists to assess the extent of the environmental problems in this part of the world. No doubt that these exchanges were the main success of the workshop marked by very stimulating discussions. Such meeting was also the opportunity to put on the first stone of a scientific network focused on the subject of the workshop. The importance of pollution in Central Asia in general and in Kazakhstan in p- ticular is a well-known feature and several references are available on the source and localization of pollution problems in those countries. The references are also abundant on the impact of the environmental failures on human health.

Hematology data from in vivo toxicology studies remains one of the most predictive measures for human risk, as the same measurements made in pre-clinical toxicology studies can be made in early clinical trials. Covering the three main blood cell types - erythrocytes, leukocytes and thrombocytes, this work is designed to clarify topics for new entrants to the fields of laboratory animal hematology and toxicology, especially those topics where the rules for human hematology do not always apply. An entire chapter is devoted to immunotoxicology, a scientific discipline that is closely aligned with hematology. The text also addresses pre-analytical and analytical variables that affect animal studies, as these play a far more important part when interpreting data in contrast to humans where many of these variables can be well controlled or have less physiological effect. Information has been collated from published papers, textbooks and unpublished data: Readers are provided with key references to encourage further study
