This book was released on 2019-09-11 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of document is to provide fact based overview of ASF ecology in the Northern and Eastern European populations of wild boar and briefly describe a range of practical management and biosecurity measures or interventions, which can help stockholders in the countries experiencing large scale epidemic of this exotic disease to address the problem in a more coherent, collaborative and comprehensive way. The handbook should not be viewed as an authoritative manual providing readymade solutions on how to eradicate ASF from wild boar. The facts, observations and approaches described in the document are presented with the intention to broadly inform veterinary authorities, wildlife conservation bodies, hunting community, farmers and general public about complexity of this novel disease and the need to wisely plan and carefully coordinate any efforts aiming at its prevention and control.

Available in PDF, EPUB and Kindle. Book excerpt: Vaccines have historically been considered to be the most cost-effective method for preventing communicable diseases. It was a vaccine that enabled global eradication of the dreaded disease smallpox. Mass immunization of children forms the anchor of the strategy of the World Health Organization (WHO) to attain "health for all" status by the year 2000. Vaccinology is undergoing a dimensional change with the advances that have taken place in immunology and genetic engineering. Vaccines that confer short or inadequate immunity or that have side effects are being replaced by better vaccines. New vaccines are being developed for a variety of maladies. Monoclonal antibodies and T cell clones have been employed to delineate the immunodeterminants on microbes, an approach elegantly complemented by computer graphics and molecular imaging techniques. Possibilities have opened for obtaining hitherto scarce antigens of parasites by the DNA recombinant route. Better appreciation of the idiotypic network has aroused research on anti idiotypic vaccines. Solid-phase synthesis of peptides is leading to an array of synthetic vaccines, an approach that is expected to attain its full potential once the sequences activating suppressor cells are discovered and the rules for presentation of antigens to T and B cells are better worked out. A new breed of vaccines is on the horizon that seeks to control fertility. Originally conceived to intercept a step in the reproductive process, they are conceptual models for developing approaches to regulate the body's internal processes.

Download or read book Clinical Disease and Host Response of Nursery Pigs Following Challenge with Emerging and Re emerging Swine Viruses written by Megan C. Niederwerder and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging viral diseases cause significant and widespread economic losses to U.S. swine production. Over the last 25 years, porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2) and porcine epidemic diarrhea virus (PEDV) have emerged or re-emerged, costing the industry billions through increased mortality and clinical or subclinical reductions in growth. Nursery pigs are greatly affected by these viruses due to high susceptibility to primary and secondary infections after weaning. However, clinical disease occurs in only a subpopulation of infected pigs and can vary drastically from sudden death to poor growth performance. This thesis documents a series of 4 studies where nursery pigs were challenged with either PRRSV/PCV2 or PEDV; the associations between clinical outcome and several factors affecting viral pathogenesis were investigated. In the first study, the administration of PRRS modified live virus vaccine prior to co-challenge with PRRSV/PCV2 was shown to protect against PRRS but enhance PCV2 replication and pathogenesis. This study provides insight into the role that PRRS vaccination has in both the control and potentiation of clinical disease. In the second study, microbial populations were compared between pigs with the best and worst clinical outcome following PRRSV/PCV2 co-infection. Increased fecal microbiome diversity was associated with improved clinical outcome; however, worst clinical outcome pigs had prolonged and greater virus replication, highlighting the host response to viral challenge as a primary determinant of clinical outcome. In the third study, 13 clinical phenotypes were compiled for>450 pigs after PRRSV/PCV2 co-infection. Duration of dyspnea and the presence of muscle wasting had the strongest associations with reduced weight gain. This study highlights the opportunity to improve animal welfare and production through improvements in clinical health. In the fourth study, clinical disease was mild to moderate and occurred within the first week after pigs were challenged with PEDV. However, PEDV was detected weeks after clinical disease had resolved and may implicate nursery pigs as an important source of viral carriage and transmission. Overall, the goal of this thesis was to develop models for understanding the impact of emerging and re-emerging viruses to improve recognition and control of disease.

Download or read book Adaptation of Porcine Reproductive and Respiratory Syndrome Virus to Modifications in CD163 written by Naemi Shadipeni and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Porcine reproductive and respiratory syndrome (PRRS) is an economically important disease of pigs caused by porcine reproductive and respiratory syndrome virus (PRRSV), a virus endemic to most pork producing countries. CD163, a surface receptor expressed on porcine alveolar macrophages (PAMs) is required for infection. Genetically modified pigs with a complete CD163 knock out are non-permissive for PRRSV infection. CD163 is also involved in the regulation of the innate immune response and the removal of hemoglobin-haptoglobin complexes. Therefore, genetically modified pigs lacking complete CD163 may suffer health consequences. Scavenger receptor cysteine rich domain 5 (SRCR5), one of the nine extracellular domains of CD163, forms the point of interaction between CD163 and PRRSV. Mutations in domain 5 were created by inserting proline-arginine (PR) dipeptides in the SRCR5 genome along the domain 5 polypeptide. Constructs were expressed in HEK cells and infected with PRRSV. Mutations were placed in three groups: 1) infection levels similar to WT-CD163; 2) mutations that produced a severe effect on infection; and 3) mutations that resulted in a moderate reduction of infection. The hypothesis tested in this project is that serially passaging PRRSV on HEK cells expressing modifications on SRCR5 of CD163 will result in adaptation of viruses to the CD163 modifications. Furthermore, adaption will be the result of mutations in PRRSV surface envelope glycoproteins, GP2, GP3 or GP4. To test this hypothesis, PRRSV was repeatedly passaged in cells expressing modifications in CD163. Viral sequences were analyzed for the presence of mutations and viral growth patterns were assessed. After six passages, adaptations to PR-22 and PR-58 mutant CD163 constructs were located in non-surface region of the PRRSV matrix (M) protein. The mutation in PR-22 was a threonine to isoleucine substitution at position 141 (T141I) in the endodomain region. The mutation in PR-58 was a tyrosine to histidine substitution at position 86 (Y86H) in the third transmembrane domain region of M. The results show that mutations in PRRSV occur in response to serial passage on cells expressing modified CD163 proteins; however, mutations were not located in the surface glycoproteins, but in the nonglycosylated M protein.
