This seminar referred to latent herpes virus infections in veterinary medicine, with emphasis on the domestic animals. The phenomenon of latency is of particular importance in veterinary medicine because it can jeopardize the successful control and eradication of diseases such as Aujeszky's disease and infectious bovine rhinotracheitis, diseases which are often the cause of great economic losses. For this reason, the Commission of the European Communities (CEC) realized the importance of summarizing the present state of knowledge on latent herpes virus infections in veterinary medicine. A seminar was therefore organized by the Federal Research Institute for Animal Virus Diseases in Ttibingen, Federal Republic of Germany, from September 21 to 23, 1982, as a part of the 'Animal Pathology Programme' of the CEC. The seminar was attended by 50 participants not only from the countries of the CEC, and 38 papers were selected for presentation. In veterinary medicine, more intensive investigations on the latency of animal herpes viruses have only relatively recently been initiated. In contrast, great efforts have been made for many years to elucidate latency in human and primate herpes viruses, and consequently the most considerable advances have been made in this field. Some of the most experienced scientists working on both systems were therefore invited. As a result, this seminar was the first occasion on which scientists from different countries and faculties investigating herpes virus latency had the opportunity to present and exchange their latest results. The.

Hardbound. As its title suggests, this book is intended to give exhaustive information on virus infections and diseases occurring in ruminants. Each virus and corresponding disease is described in a separate chapter, and the chapters are ordered according to current virus classification. Contributing authors are experts on the virus and disease they describe. Where necessary, the text is accompanied by tables and pictures. The accent is placed on diagnosis of the disease by clinical observations including epizootological data. There is also a description of the laboratory procedures of diagnostic virology, and suggestions concerning control measures (e.g. vaccination and/or eradication policy).This book should prove indispensable to: the practising veterinarian, by facilitating recognition of a viral disease, and giving advice on collecting appropriate specimens for laboratory investigation; the veterinary virologist by aiding the choice of appropriate

The book focuses on the ecology of the most important infectious diseases of wild avian hosts, especially those with high morbidity and mortality rates. Disease ecology is an important scientific approach to study the relationships and interactions between living organisms, their environment, and potential pathogens. Birds have high diversity, and the very special ability to fly and migrate. They migrate over long distances, and share ecosystems with other animals, even humans. They serve as the most important natural source of several pathogens with zoonotic potential. Bird-pathogen interactions are increasingly changing due to the continuous anthropogenic disturbances in habitats and ecosystems. With intensified climate change and improved environmental conditions for vectors, as well as higher susceptibility of avian hosts due to simultaneous exposure to environmental stressors (e.g., contamination, food limitation, etc.), the probability of emerging new infections and their expansion into new territories increase tremendously. The Covid-19 pandemic has shown that neglected ecological and epidemiological interactions between wildlife, domestic animals and humans are paramount to global health. The book has a different approach to understanding complex and multiscale interactions among various ecological factors for the most important infectious diseases of wild birds. It provides valuable data to students and everyone who deals with avian species including biologists, researchers, conservationists, and policymakers.

This timely publication describes the botanical sources and chemical features of antiviral compounds. It covers their mechanisms of action and evaluates their therapeutic potential. Included is a discussion of synthetic analogues where appropriate. The book states that antiviral compounds in so-called medicinal plants may constitute some of their "active ingredients." It explains that many are photosensitizers, their antiviral activity dependent upon or augmented by light of specific wavelengths. This book is of value to microbiologists, phytochemists, virologists, natural-product chemists, ethnobotanists, pharmacologists, medical and veterinary researchers, and others interested in the application of plant compounds to therapy of infectious diseases.

A great truth is a truth whose opposite. is also a great truth. Thomas Mann (Essay on Freud, 1937) This volume centers on pseudorabies (PR V), herpes simplex viruses 1 and 2 (HSV-1 and HSV-2), and human cytomegalovirus (CMV) and fulfills three objectives. The chapters on the epidemiology and latency of HSV, and on the glycoproteins specified by HSV and CMV, set the stage for the discussions of the immunobiology and pathogenesis of human herpesvirus infections in Volume 4. The epidemiology of HSV is the basis of our understanding of the spread and survival of this virus in the human populations. Central to the epidemiology of HSV and its pathogenesis in humans is the ability of the virus to remain in a latent state for the life of its host. The viral membrane glycoproteins are among the most interesting virion proteins, primarily because of their critical role in the initiation of infection. Since they are the surface membrane proteins of the virion and appear on the surface of productively infected cells, they are also the obvious if not the exclusive targets of the immune response. The chapters on the transforming potential of HSV and CMV, and on the role of HSV in human cancer, deal with challenging problems requiring rather different experimental tools.

This book is based on the proceedings of a seminar on acute viral in fections of poultry, which was held in Brussels on 13-14 June 1985. The aim of the seminar, which was sponsored by the CEC, was to gather infor mation on those infections of immediate or increasing importance. It is hoped that dissemination of this information will make it easier to har monize diagnostic and control measures throughout the member states of the EEC. Several points emerge from recent outbreaks of highly pathogenic avian influenza. In view of the apparent change in pathogenicity of the virus involved in the outbreak in the USA, infections of domestic poultry, particularly with H5 and H7 sub-types, should be regarded as a potential threat, even if the viruses involved are of low pathogenicity. The reasons for the amount of lateral spread which occurred in the USA outbreak are still not clear, and it can not be assumed that future outbreaks of highly pathogenic avian influenza will tend to be self-limiting, as in the past. The importance of denying access of wild birds, particularly water fowl, to domestic poultry needs to be re-emphasised. Lastly, there appears to be increasing support for a combination of slaughter and ring vaccination to control future outbreaks of spreading avian influenza.

Now in a much-anticipated two-volume new edition, this gold-standard reference stands as the most comprehensive and authoritative text on equine reproduction. Serving theriogenologists, practitioners and breeders worldwide as a one-stop resource for the reproductive assessment and management of equine patients, Equine Reproduction, Second Edition provides detailed information on examination techniques, breeding procedures, pregnancy diagnosis and management, reproductive tract diseases and surgery, and foaling. A companion website offers hundreds of images from the book in color. For the Second Edition, the stallion, mare and foal sections have been thoroughly updated and revised to include the latest information on every subject. New topics include discussion of nutritional and behavioral factors in the broodmare and stallion, parentage testing, fetal sexing and the health and management of older foals, weanlings and yearlings. Additionally, this outstanding Second Edition features a new section on assisted reproductive techniques, including detailed information on artificial insemination, in-vitro fertilization, embryo transfer and technology.
