Contrary to common belief, infectious diseases are not as well under control as we would like. We are now at a crossroads regarding the impact of the environment on infectious diseases. Renewed interest in biological weapons and the emergence of new pathogens, coupled with a better understanding of the impact of infectious agents on other conventional diseases, has led us to realise that we can no longer remain complacent about the impact of infectious agents on human, animal and crop health. The present book first discusses current and emerging military and civilian policies on the environment. In addition, the impact of environmental biology on the future of space exploration is discussed, especially in reference to the Mars mission. There follows a discussion of the state of bacteria in the environment, with a presentation of current and emerging techniques of microbial investigation. Finally, two case studies are presented on the impact of these techniques on both political and environmental problems.

The most rewarding aspect of writing a book is receiving encouraging comments from one's colleagues, since one always wonders whether fair coverage was made of the work of others or whether some omissions were made. I feel very fortunate that many colleagues took the time to read the first edition of this book and chose to use it as a textbook in their teaching. During the past few years they have given me valuable suggestions by pointing out areas that needed to be added to improve the book. Toxicology is one of the fastest moving scientific fields. In the areas of insecticide toxicology many new advances have been made since this treatise first appeared. Therefore, it would not be easy to write even a review paper that would not be outdated by the time it was published. In revising this volume I have made a conscious effort to adhere to the basic principles which have been developed over the years. While I have retained the basic framework of the original book, advances that fundamentally change certain concepts or add a new horizon have been chosen for updating those fields where applicable. The main emphasis has been placed on the addition of new sections and new compounds developed since 1975. Since the first edition appeared, several books covering technical details in each group have been published. They are excellent encyclopedic resources in their chosen areas, and are listed in each section as recommended reading material.

"Complementary and Alternative Veterinary Medicine Considered" is a book that belongs in your veterinary library. If you are a veterinarian wondering if you should incorporate complementary and alternative veterinary medicine (CAVM) into your practice, if you have recently hired an associate eager to try such things as acupuncture or homeopathy, or if you have clients asking you about chiropractic, herbal, or magnetic field therapy for their pets, you'll want to understand the history, science and ethics behind such therapies.

In its 2001 "Guidelines for Complementary and Alternative Medicine," the American Veterinary Medical Association (AVMA) recognizes the growing interest in CAVM, and encourages the critical examination of these therapies using the scientific method. Following the AVMA's lead on this subject, "Complementary and Alternative Veterinary Medicine Considered" thoroughly examines a variety of CAVM therapies and asks important questions regarding alternative treatments. For example, is acupuncture effective in pain relief? What is homeopathy? What is the history behind chiropractic? What does the research say (and not say) about various CAVM modalities? And, just as importantly, what are the ethical and regulatory considerations concerning such therapies? This book has the answers to those questions and more.

"Complementary and Alternative Veterinary Medicine Considered" will help practicing veterinarians to make informed decisions about specific CAVM therapies. This text evaluates various prevalent therapies, and will give veterinarians the ethical and scientific bases they need to make sound decisions regarding CAVM therapies

Coverage includes but isnot limited to:
Acupuncture and acupressure;
Energy medicine;
Manual therapy (chiropractic);
Manual therapy (massage);
Magnetic and electromagnetic therapy;
Laser and light therapy;
Homeopathy; and
Herbal therapy.

The use of ultrasonic imaging techniques for diagnostic purposes in veteri nary medicine and animal science has lagged far behind their use in human medicine. In the area of domestic animal reproduction, diagnostic ultrasono graphy has a relatively short history. Reports on B-mode scanning first appeared as late as 1969, when Stouffer and co-workers used it for counting foetal numbers in late gestation sheep. After Lindahl had re-evaluated the potential of two-dimensional ultrasonography for pregnancy diagnosis in sheep in 1976, results of the first large scale field-trials by Fowler and Wilkins on predicting foetal numbers during the first half of gestation in sheep were published as recently as 1980. In this year also the first paper, by Palmer and co-workers, on ultrasonic scanning of the uterus and ovaries in the mare appeared. The improvement of diagnostics which was achieved by the application of this technique is illustrated by its present routine use in clinical equine practice and sheep breeding. Besides offe ring an accurate early pregnancy diagnosis in species such as the horse, cow, sheep, goat, pig and dog, ultrasonography enables the visualization of ovarian and uterine structures for the identification of both physiological and pathological conditions. In this way it replaces or supplements the more common diagnostic techniques used by the general practitioner so far. Ultrasonography has also opened several new lines of research for clini cians and research workers."

This volume provides an overview of the latency strategies developed during the estimated 200 Myears long coevolution of Alpha-, Beta- and Gammaherpesvirinae and their host species. The main emphasis is on herpesviruses infecting humans. However, relevant cases if herpesviruses infecting animals are covered as well. Special emphasis is drawn on results on molecular mechanisms regulating latent promoters of herpesvirus genomes and signals and molecular pathways resulting in reactivation of latent viral genomes. To balance the volume, epigenetic mechanisms (DNA methylation, histone modification, chromatin structure) involved in cell type specific expression of growth-transformation-associated Gammaherpesvirus genes will also be discussed at length)

In recent years nobody could have failed to notice the frequent and often sensati- alist media headlines warning of the latest global disease threat to humankind. But behind all the hyperbole lie real challenges related to dealing with the increasing incidence of emerging zoonotic disease events, the majority of which are thought to originate in wildlife (Jones et al. 2008). There are also many important diseases of domestic livestock which also occur in wildlife (e. g. foot and mouth disease and classical swine fever in wild boar, bovine tuberculosis in deer, badgers or possums), some of which can have a devastating impact on the farming industry, the wider rural economy and ultimately the public purse. But we should also not forget that wildlife diseases may have serious implications for the conservation of biodiversity. For some of the rarest, most endangered species (such as the Ethiopian wolf) d- ease may pose the greatest threat to their survival. If we are to avoid or reduce these impacts then we must improve our ability to detect and manage the risks associated with disease in wildlife populations. This is a challenge that will require expertise from many different disciplines: veterinary, ecological, medical, economic, poli- cal and zoological. In such an interdisciplinary field it is difficult to stay up to date with contemporary ideas and with techniques that may be rapidly evolving.

Safety of Meat and Processed Meat provides the reader with the recent developments in the safety of meat and processed meat, from the abattoir along the processing chain to the final product. To achieve this goal, the editor uses five approaches. The first part deals with the main biological contaminants like pathogen microorganisms, specially E. coli and L. monocytogenes, toxins and biogenic amines that can be present either in meat or its derived products. The second part focuses on main technologies for meat decontamination as well as developments like active packaging or bioprotective cultures to extend the shelf life. The third part presents non-biological contaminants and residues in meat and meat products including nitrosamines, PAH, veterinary drugs and environmental compounds. The fourth part discusses current methodologies for the detection of microorganisms, its toxins, veterinary drugs, environmental contaminants and GMOs, and the final part deals with predictive models, risk assessment, regulations on meat safety, consumer perception, and other recent trends in the field. This book is written by distinguished international contributors with excellent experience and reputation. In addition, brings together advances in different safety approaches.

As aquaculture continues to expand there is a need for greater knowledge of medicinal treatments both for the prevention and treatment of disease and for the economic husbandry of fish. This book, the first of its kind, is written for a worldwide readership. It is a reference manual for anyone involved in the selection of medicines for administration to fish. It will also be useful to administrators concerned with the legal control of aquaculture. The first part covers issues which affect all medicine's methods of administering drugs to fish, the various aspects of safety and the relevant legislation in countries with important aquacultural industries. Subsequent parts review the range of available medicinal substances and present current knowledge of the pharmacology and methods of use for each. Particular attention is given to safety issues - for the fish, for the person administering the medicine, for the consumer of medicated fish and for the environment.

Gonadotropin-releasing hormone (GnRH) cells are the key regulators of reproductive function in all vertebrate organisms. The GnRH molecule is synthesized in a small number of neurons in rostral hypothalamic regions of the brain. In mammals, these neurons release the GnRH decapeptide into the portal capillary system leading to the anterior pituitary gland. There, GnRH causes the release of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn act upon the gonads to stimulate their maturation, and to cause synthesis of sex steroid hormones, estrogen, progesterone and testosterone. Although each of the levels of the hypothalamic-pituitary-gonadal axis is critical for reproductive function, GnRH neurons play the primary role in the control of reproductive maturation and adult reproductive function, and may even play a role in reproductive senescence.

Since its discovery in 1970, there has been intense interest in GnRH-producing neurons, with more than 8000 papers and chapters in the last decade alone. Despite this activity of research in basic and clinical science, there has never been a book written specifically on GnRH neurons. GnRH: The Master Molecule of Reproduction aims to bring together the large and diverse literature of both laboratory and applied research that focuses on these unique cells.

This book will provide basic background into reproductive neuroendocrinology, as well as specifics regarding the role of GnRH neurons in the control of reproduction. Students studying endocrinology, reproduction, neuroendocrinology or molecular endocrinology will benefit from this book. In addition, this book will take a multi-species approach which will be useful both to basic researchers as well as clinicians. Whenever possible, species differences and similarities will be presented, and if possible, studies on humans, or the clinical relevance of basic research findings to humans will be discussed (such as the treatment of reproductive disorders such as abnormalities in pubertal development, or infertility).

Animal welfare is attracting increasing interest worldwide, but particularly from those in developed countries, who now have the knowledge and resources to be able to improve the welfare of farm animals. The increased attention given to farm animal welfare in the West derives largely from the fact that the relentless pursuit of ?nancial reward and ef?ciency has led to the development of intensive animal production systems that disturb the conscience of many consumers. In developing countries, human survival is still a daily uncertainty, so that provision for animal welfare has to be balanced against human welfare. Welfare is usually provided for only if it supports the output of the animal, be it food, work, clothing, sport or companionship. In reality there are resources for all if they are properly husbanded in both developing and developed countries. The inequitable division of the world's riches creates physical and psychological poverty for humans and animals alike in many sectors of the world. Livestock are the world's biggest land user (FAO, 2002) and the population is increasing rapidly to meet the need of an expanding human population. Populations of farm animals managed by humans are therefore incre- ing worldwide, and in some regions there is a tendency to allocate fewer resources, such as labour, to each animal with potentially adverse consequences on the a- mals' welfare.

The domestic pig is perceived as an animal with intelligence and character and yet, in the industrialized world, the majority of people have had little or no contact with them. Pigs are subject to a wide range of environments from the tropics to the sub-arctic, ranging from small-scale, extensive systems to large-scale intensive systems. They may spend their whole life on one farm or may be subject to long-distance transport multiple times. Not surprisingly, many aspects of their life experiences can impact their welfare.

This book brings together a team of leading pig welfare research scientists to review the natural history of the pig, the welfare of pigs at different stages of life and to indicate what the future holds in terms of pig welfare. The text is aimed at researchers and teachers working in veterinary and animal science together with those working in the pig industry and for governmental and non-governmental animal welfare organizations.

Man's attempts to learn about aspects of the human body and its functions by observation and study of animals are to be found throughout history, especially at times and in cultures where the human body was considered sacrosanct, even after death. This book describes the origins and later development, especially in the eighteenth and nineteenth centuries, of comparative medicine and its interrelationship with medicine and veterinary medicine and the efforts of its practitioners to understand and control outbreaks of infectious, epidemic diseases in humans and in domestic animals. In the nineteenth century their efforts and increasing professionalism led to the creation of specialised institutes devoted to the study of comparative medicine. Paradoxically the first such institute, the Brown Institution, opened in London in 1871, despite the fact that the study of this branch of medicine in Britain had always lagged behind that in France and Germany. The book discusses the rise and fall of this centre and describes how it was soon overtaken in importance by the great institutes in Paris and Berlin and then, from the turn of the century, by American institutes, funded by private fortunes. This book sheds much new light on the medical and veterinary history of this period and will provide a new perspective on the history of bacteriology.

GRACEY'S MEAT HYGIENE Gracey's Meat Hygiene, 11th edition, is the definitive reference for veterinarians working in meat hygiene control. This new edition of a classic text reflects the recent significant changes in science, legislation and practical implementation of meat hygiene controls in the United Kingdom, Europe and worldwide since the 10th edition was published in 1999. This book is an excellent practical guide for teaching food hygiene to veterinary students worldwide, laying the foundations of food animal anatomy, the humane slaughter of animals for food and practical production hygiene. New chapters address the increased concern of operators, inspectors and the public to issues of animal welfare and recognise the role of the profession, and interest from the consumer, in environmental protection. Key features include the following Fully updated new edition, in a refreshed design with colour photographs and illustrations throughout Includes new content on meat hygiene inspection covering the components of an integrated food safety management system as well as animal health and welfare controls in the 'farm to fork' system A practical approach to health and safety in meat processing is outlined by identifying the hazards and then describing how these can be best controlled With contributions from veterinary and industry experts, this edition is both a valuable teaching aid and a practical reference for veterinarians and all food business operators and their staff

Written for veterinary undergraduates, this comprehensive text explores the often obscured link between disease at the cell and tissue level, and that encountered by the working clinician. Based on a course taught by the editors, the book attempts to strike a balance between the needs of the student and specialist knowledge. Each chapter explains patterns of disease in particular organs and relates them to both the pathophysiologic changes and the outward appearance of the sick animal.

First published in 1936, Colyer's Variations and Diseases of the Teeth of Animals drew extensively on the material housed in the Odontological Museum of the Royal College of Surgeons of England, and quickly became an indispensable reference for students and research workers in zoology, archaeology and veterinary science, as well as human dentistry. In this second edition, Colyer's successors at the Odontological Museum have fully revised the text in the light of new knowledge, while preserving the best of Colyer's own material. The text has been rearranged taxonomically and a new introduction reviewing conceptual advances in the field since Colyer's time has been added. The numerous illustrations, classics of their kind, have been reproduced to a high standard from Colyer's originals and many new figures have been incorporated. This revision will introduce Colyer's material to a new audience, for whom it represents a comprehensive and fully-referenced survey of abnormalities and diseases of the teeth and jaws of animals.
