Download or read book Challenge Studies in Chickens to Evaluate the Efficacy of Commercial Newcastle Disease Vaccines Against the Strains of Newcastle Disease Virus Prevalent in South Africa Since 2002 written by Dauda Garba Bwala and published by . This book was released on 2009 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 2002, the South African poultry industry has experienced outbreaks of Newcastle disease (ND) caused by a newly introduced virus (NDV) strain belonging to lineage 5d/VIId ("goose paramyxovirus" - GPMV). Control of the disease has proved difficult with commercially available vaccines appearing ineffective. In the first of two studies, broilers chicks were vaccinated with VG-GA vaccine (lineage II), then challenged with both GPMV and a "classic" challenge virus (RCV) of lineage 3d/VIII to compare the efficacy of the vaccine against both strains. In the second study, commercial and SPF hens in lay were vaccinated with La Sota vaccine and challenged with GPMV isolate, and immunohistochemistry staining used to determine the distribution pattern of viral antigen in the oviduct of the hens. Results from the second study showed no clear difference in the protection of the oviduct from challenge with GPMV by either the cloacal and ocular routes of vaccination. Vaccinated birds were fully protected (100%) against challenge by La Sota vaccine, but not against infection and replication of the virus, as birds showed varying degrees of macropathology with numerous stained viral antigens in the oviducts demonstrated by immunohistochemistry. The susceptibility and colonisation of the oviduct of laying hens by both the lentogenic La Sota and the virulent NDV isolates was confirmed, with the uterus being more susceptible than magnum and isthmus. Necrosis and apoptosis of cells of the oviduct were not detected but cellular infiltration, gland dilatation and interstitial oedema were observed.

Available in PDF, EPUB and Kindle. Book excerpt: With the growing global fear of a major pandemic, avian influenza (AI) virus research has greatly increased in importance. In Avian Influenza Virus, an expert team of researchers and diagnosticians examine the fundamental, yet essential, virological methods for AI virus research and diagnostics as well as some of the newest molecular procedures currently used for basic and applied research. They present exciting, cutting-edge new methods that focus both on studying the virus itself and on work with avian hosts, an area greatly lacking in research.

Download or read book Avian Influenza and Newcastle Disease written by Illaria Capua and published by Springer Science & Business Media. This book was released on 2009-06-24 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Previously released in June 2004 and temporarily withdrawn. Now available!) Keeping poultry contributes substantially to household food security throughout the developing world. One of the principal constraints to increasing small-scale poultry production is Newcastle Disease. This acute viral disease can typically kill up to 80 percent of unprotected poultry in rural areas and is found throughout the developing world. This technology review presents the latest understanding of Newcastle Disease, its characteristics, epidemiology, symptoms, and control. It will be of practical value to state and private veterinarians, and to all those involved with rural poultry production who wish to control this disease.

Download or read book The Geographical Distribution of Animal Viral Diseases written by Stewart Hal and published by Elsevier. This book was released on 2012-12-02 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Avian Immunology written by Bernd Kaspers and published by Academic Press. This book was released on 2012-12-02 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. - With contributions from 33 of the foremost international experts in the field, this book provides the most up-to-date review of avian immunology so far - Contains a detailed description of the avian innate immune system reviewing constitutive barriers, chemical and cellular responses; it includes a comprehensive review of avian Toll-like receptors - Contains a wide-ranging review of the "ecoimmunology" of free-living avian species, as applied to studies of population dynamics, and reviews methods and resources available for carrying out such research
