Download or read book Efficacy of Newcastle Disease Virus Vaccines in Broiler Chickens written by Mohammad Showkat Mahmud and published by LAP Lambert Academic Publishing. This book was released on 2013-01 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Newcastle disease is a highly contagious viral disease affecting many domestic and wild avian species that have severe impact on poultry industry.It can also be transmitted to humans that cause conjunctivitis and flu like symptoms. Effective vaccination of flock is the means to control this disease. This book was to investigate persistence of maternal antibody as well as the comparative efficacy of Avinew and BCRDV vaccines against Newcastle disease in chicks. Birds of groups A and B were primarily and secondarily vaccinated with Avinew and BCRDV respectively at the age of day 3 and 20. Sera samples were obtained from 10 randomly selected birds on each occasion of day 1, 10, 17, 27, 30, 34 and 44 of age of birds. Birds of group C were maintained as unvaccinated control for the determination of existence of maternal antibody. Thus it was indicated that performance of Avinew in respect of elucidation of HI antibody was comparatively better than that of BCRDV and maternal antibody against NDV in chicks persisted to a minimal until the age of day 27 and none at day 30 or 34. This analysis will be useful to professionals working for poultry industry, researcher and vaccine manufacturer.

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.

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.

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

Available in PDF, EPUB and Kindle. Book excerpt: Marek's disease virus (MDV) is a herpesvirus which causes a lymphoproliferative disorder of the domestic chicken worldwide. This serious economical problem caused by MDV was mostly solved by development of an effective vaccine against MDV. The development of live vaccines against the disease is remarkable as it has led to the first example of a commercially available vaccine against cancer as well as against diseases caused by herpesviruses.This volume gives an overview on many aspects of MDV research and summarizes recent advances in the field. The topics include the history, biology,and molecular biology of MDV, pathogenesis, vaccinal immunity, immune response, genetic resistance and development of recombinant polyvalent vaccines. It is hoped that this volume will make an important contribution towards the control of infectious diseases.
