This book was released on 2011 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The poultry red mite Dermanyssus gallinae (De Geer) is a blood feeding ectoparasite that infests many bird species. Economically it is the most important parasite affecting egg-laying hens. The aim of this study was to identify vaccine candidate proteins from D. gallinae using a number of approaches. An immunisation trial was conducted using four protein fractions derived from D. gallinae. The fractions were injected into hens and immunoglobulin Y was purified from the yolk of eggs laid by the hens. An in vitro feeding assay in which mites were fed these antibodies showed a significant increase (p = 0.013) in mortality of mites fed with antibodies against a PBS-soluble fraction of D. gallinae. The PBS-soluble proteins were then fractionated by anion exchange chromatography into three fractions, which were then used to immunise hens. One fraction produced antibodies that caused the greatest percentage mortality of mites, based on the results from a single feeding assay. To identify further potential vaccine antigens, three expressed sequence tag (EST) databases were produced. A complementary DNA (cDNA) library was prepared from a mixed gender and life stage population and 46 contigs were identified with significant homology to proteins from other organisms. A second database was generated using a suppression subtractive hybridisation approach and 133 "fed mite enriched" contigs identified with significant homology to proteins in either the NCBI non-redundant (nr) protein, KEGG databases or had a domain predicted by InterProScan. The most abundant proteins in this database were vitellogenin and GP80, a precursor molecule of vitellogenin. Roche 454 sequencing technology was used to generate an EST database of 13,363 contigs, of which 26 % had significant homology to a protein in the NCBI nr protein database. The majority of contigs (45 %) were classified as Cellular Processes and Signalling proteins. Illumina Solexa sequencing technology was also used to analyse the expression levels of genes in fed and starved mites. A total of 66 contigs were obtained with a significant and greater than three-fold change in expression level between the two groups. The contig with the largest fold change was homologous to vitellogenin (fold change 110). Paramyosin and tropomyosin have been used successfully to immunise hosts against other parasitic species. Tropomyosin had previously been characterised in D. gallinae. In this study paramyosin was characterised and recombinant versions of both proteins were used in an immunisation trial. Anti-tropomyosin (p

Download or read book Parasitology and Microbiology Research written by Gilberto Antonio Bastidas Pacheco and published by BoD – Books on Demand. This book was released on 2020-06-17 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of both unicellular and multicellular living beings and the diseases they produce from a biological point of view requires constant review of their relationship with their host and environment, given their indisputable sanitary importance. In this sense, in parasitology and microbiology, updated and concise information on life cycle, taxonomic classification, clinical manifestations, diagnosis, treatment, epidemiological behavior, and control measures is of vital importance. This is what we pursue with this book. The approach to parasitology and microbiology and the research that is carried out on it is unquestionable because the associations between life forms have been present from the very beginning of life.Research in parasitology and microbiology is necessary and indispensable for controlling diseases that affect much of the world with serious economic and social consequences. The challenge is to promote research to keep these diseases at bay. This book shows what has been done up to now and what can be done in the future to combat infectious diseases.

Download or read book Parasitism The Good The Bad and The Ugly written by Marco A. Juarez-Estrada and published by Frontiers Media SA. This book was released on 2023-11-07 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitism is a tight association between species in which one organism, the parasite, lives on or inside the host, causing it harm, and is structurally adapted to this way of life. Until the twenty-first century, parasitism was studied by parasitologists, rather than ecologists or evolutionary biologists. Today, parasitism is a major element of evolutionary ecology, as nearly all free-living animals are hosts to at least one parasite species. Since it is in the parasite's evolutionary interest for its host to flourish, long-term coevolution can lead to a stable relationship bordering on mutualism. According to Lynn Margulis, when resources are scarce, natural selection, moves relationships from parasitism to mutualism, as it was brilliantly illustrated in Margulis' endosymbiosis theory, where eukaryotic mitochondria and chloroplasts descended from formerly free-living prokaryotes. Boundary between mutualism, symbiosis, and pathological parasitism is a thin red line that frequently overlapping without a theory enough clear to explain this thigh relationship between the parasite and its host.

Download or read book Tick Host Pathogen Interactions written by Sarah Irène Bonnet and published by Frontiers Media SA. This book was released on 2018-08-24 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Besides causing direct damage associated with blood feeding and in some cases through the excretion of toxins with their saliva, the main relevance of ticks lies in the wide variety of pathogens that they can transmit, including viruses, bacteria, protozoa and helminths. Owing to socioeconomic and environmental changes, tick distribution is changing with incursions of ticks and tick-borne diseases occurring in different regions of the world when the widespread deployment of chemical acaricides and repellents has led to the selection of resistance in multiple populations of ticks. New approaches that are environmentally sustainable and that provide broad protection against current and future tick-borne pathogen (TBP) are thus urgently needed. Such development, however, requires improved understanding of factors resulting in vector competence and tick-host-pathogen interactions. This Research Topic provides an overview of known molecular tick-host-pathogen interactions for a number of TBPs and highlights how this knowledge can contribute to novel control and prevention strategies for tick-borne diseases.
