Newcastle Disease

Avian Influenza (AI) and Newcastle Disease (ND) are two devastating diseases of poultry, which cause losses to the poultry industry and influence the liveability of rural communities worldwide. Following the H5N1 epidemic they appear to be endemic at least in Asia, Eastern Europe, The Middle East and Africa. Particularly in case of AI outbreaks it is essential that infection is diagnosed promptly and that isolates are made available to the international scientific community. Currently, several organisations including OIE, FAO and the EC have organised training courses in affected areas. However, often these courses do not cover all aspects of AI/ND diagnosis but only certain aspects. This results in fragmented areas of knowledge and in the application of different diagnostic protocols in different parts of the world. The objective of this book is to provide a comprehensive approach to AI diagnosis ranging from the clinical elements that should trigger a suspicion in the field, to the post mortem technique, collection of samples, processing/ shipment of specimens, virological, serological and molecular diagnosis and guidelines for notification.

Most of the chapters of this book were written during 1987 which was the Diamond Jubilee year of the publication of the first reports of Newcastle disease in 1927. During the intervening years the nature of the Poultry Industry throughout the World has changed, or is in the process of changing, dramatically from one based on small village or farm flocks, frequently kept as a sideline, to an industry based on large flocks, sometimes consisting of hundreds of thousands of birds, run by multinational companies. To all these flocks, both large and small, Newcastle disease poses a considerable threat to their well-being and profitability and it is not unreasonable to state that hardly a single commercial flock of poultry is raised in the world without Newcastle disease having some effect due to actual disease, prophylactic vaccination or restrictions placed on rearing, movement, processing, sale or export of birds and products. In addition, recent years have produced developments in virology and associated biological technology which would have been unbelievable when Newcastle disease virus was first isolated. The economic importance of Newcastle disease virus and its use as a laboratory model has meant that major advances have been quickly applied to the field situation whenever possible and, as a result, a much fuller understanding, not only of the biochemistry and basic virology of the virus but also the ecology, epizootiology, antigenicity, immunology and other important aspects in the control of the disease has been achieved.

The most complete and definitive reference to all aspects of poultry diseases, Diseases of Poultry, Fourteenth Edition has been fully revised and updated to offer a comprehensive survey of current knowledge. Updates the definitive reference of poultry health and disease Provides more clinically relevant information on management of specific diseases, contributed by clinical poultry veterinarians Offers information on disease control in organic and antibiotic-free production Presents more concise, streamlined chapters for ease of use Incorporates advances in the field, from new diagnostic tools and information to changes brought about by the increasing globalization and the re-emergence of zoonotic pathogens

Provides a concise and authoritative reference on the use of vaccines against diseases of livestock Compiled by Senior Animal Health Officers at The Food and Agriculture Organization of the United Nations, and with contributions from international leading experts, Veterinary Vaccines: Principles and Applications is a concise and authoritative reference featuring easily readable reviews of the latest research in vaccinology and vaccine immune response to pathogens of major economic impact to livestock. It covers advice and recommendations for vaccine production, quality control, and effective vaccination schemes including vaccine selection, specifications, vaccination programs, vaccine handling in the field, application, failures, and assessment of herd protection. In addition, the book presents discussions on the current status and potential future developments of vaccines and vaccination against selected transboundary animal diseases. Provides a clear and comprehensive guide on using veterinary vaccines to protect livestock from diseases Teaches the principles of vaccinology and vaccine immune response Highlights the vaccine production schemes and standards for quality control testing Offers easy-to-read reviews of the most current research on the subject Gives readers advice and recommendations on which vaccination schemes are most effective Discusses the today’s state of vaccines and vaccination against selected transboundary animal diseases as well as possible future developments in the field Veterinary Vaccines: Principles and Applications is an important resource for veterinary practitioners, animal health department officials, vaccine scientists, and veterinary students. It will also be of interest to professional associations and NGO active in livestock industry.

Backyard Poultry Medicine and Surgery is a practical resource offering guidance on developing diagnostic and treatment plans for individual companion poultry or small flocks. Organized by body system to aid in developing a differential diagnosis list for common presenting signs, the book provides all the information clinicians need to effectively treat backyard poultry. Written by experts from both the commercial poultry field and the companion avian field, the book provides thorough coverage of both common and less common diseases of backyard chickens, ducks, and other poultry. The book begins with introductory chapters covering general information, an overview of US laws, and basic husbandry concerns, then moves into specific disease chapters organized by system. The book takes an individual medicine perspective throughout, with photographs, radiographs, and histopathological photomicrographs to illustrate principles and diseases. Backyard Poultry Medicine and Surgery is an invaluable guide to diseases and treatments for any practitioners treating backyard poultry.

The book provides a comprehensive overview of the current state, and the new concepts for the future directions of modern cancer therapy. Bringing together all the relevant aspects from basic and applied science, and the clinical experiences of this new direction in medicine, it is an up-to-date summary of the activities in the field and will be the basis for evaluating future progress in this area.

The Geographical Distribution of Animal Viral Diseases attempts to shed some light on the global distribution of 110 different viral diseases, mainly of livestock and companion animals. The world literature was screened for 110 different viruses, and maps were prepared. These maps delineate the global distribution of pathogenic viruses based on authenticated reports from a variety of reliable sources. Four viruses were categorized as affecting more than one species to a significant degree (astrovirus, rabies, rotaviruses, and Rift Valley fever). The largest number of maps involved viruses that affect humans. Of the 28 viruses a large number were from the California encephalitis group. Ten of the 28 viruses were reported only in the Eastern Hemisphere, 14 only in the Western Hemisphere, and four were worldwide. Birds were the next most frequently affected group with the 15 viruses, followed by pigs with 14 viruses. Overall the vector-borne viruses appear to have much sharper and clear-cut geographical boundaries than the others.
