This book was released on 2019 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year malaria impacts approximately 219 million people and causes over 400,000 deaths. The worldwide parasite burden remains high, even with the availability of efficacious antimalarial drugs and vector control tools such as insecticides and bed nets. Despite large investments in malaria vaccine development, there is currently no deployable vaccine for malaria. However, individuals who live in malaria endemic regions develop naturally acquired immunity (NAI). Thus, good vaccine candidates may be identified by studying serum antibody responses in malaria patients who live in endemic areas. Protein arrays, which interrogate patient serum antibody binding to many proteins simultaneously, are the primary method of antigen prioritization. However, protein arrays are fabricated by generating unpurified malaria antigens in bacteria and directly spotting lysates onto slides without validation of correct antigen folding or purification. Results from protein arrays can be affected by the sample impurity where positive binding events may be masked by background protein interactions or unrecognizable epitope presentation. Thus, technical improvements are needed to control protein production and protein exposure to patient sera. More recently, multiplexing bead-based assays have been applied to investigate malaria patient immune responses where spectrally distinct bead sets are coated with unique antigens of interest. For such assays, antigens traditionally are individually purified before coupling onto beads. To produce a more high-throughput method of patient immune response dissection using a large panel of antigens, bead-based chemistries were developed to modify multiplexing beads with a small linker molecule or with antigen capturing antibody. These modified beads capture malaria antigens directly from translation lysates, essentially purifying antigens in a single step. Both chemistries utilized the capture of recombinant antigens via a highly specific protein tag, HaloTag or C-tag. Although both systems successfully capture tagged antigens from translation lysates, the C-tag capture system proved to be more reliable and reproducible. Using recombinant malaria antigen merozoite surface protein 1 (MSP1)-coated beads and standard anti-MSP1 detecting antibodies, a 105-fold signal increase was observed in comparison to green fluorescence protein (GFP)-coated beads. Malaria patient sera responses to recombinant MSP1 were also measured. When assessed against MSP1-coated beads, serum from a high immune responsive patient gave an 8.5-fold increase in comparison to GFP-coated beads, while a low immune responsive patient gave a 2-fold increase. These results agree with previously reported protein microarray dissection of the same patient serum samples. The bead chemistries developed here make it possible to interrogate multiple malaria antigens simultaneously without demanding timely antigen purification. Furthermore, the multiplexing assay present antigen epitopes in a more accessible configuration while utilizing small amount of precious patient sera. The platform developed here will provide a high-throughput method of identifying specific patient antibody-antigen binding events and has the potential to customize bead arrays to model populations with high antigenic variation.

Finally, this volume contains several chapters on malaria vaccine development, describing the application of the most recent vaccine technologies as well as ongoing and planned vaccine trials. Authored by well-recognized experts, this volume not only demonstrates the rapid progress being made in the search for vaccines against malaria, but also broadens our understanding of immunity to infection in general. It is therefore highly recommended reading for all scientists and professionals in the fields of immunology, infection and vaccine development.
Download or read book From Malaria Control to Malaria Elimination written by World Health Organization and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this manual is to raise awareness of the sorts of technical, operational, and financial resources that would be required to reduce and eventually eliminate malaria, the timelines over which such reductions are likely to be achieved, and how they can be sustained. This knowledge is essential in order to plan strategically for long-term success. More detailed, context-specific planning will be an important next step after working through the general approach set out in the document. This document aims to assist malaria programs in evaluating whether elimination, or other reductions in malaria, represents a feasible and appropriate goal in a defined area, based on careful consideration of what reductions in transmission are likely to occur given the intrinsic malaria burden, the levels of program coverage that can be reached, and the financial investment available.

Download or read book Biology of Blood Sucking Insects written by Mike Lehane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
Download or read book Point of care testing written by Peter Luppa and published by Springer. This book was released on 2018-07-18 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The underlying technology and the range of test parameters available are evolving rapidly. The primary advantage of POCT is the convenience of performing the test close to the patient and the speed at which test results can be obtained, compared to sending a sample to a laboratory and waiting for results to be returned. Thus, a series of clinical applications are possible that can shorten the time for clinical decision-making about additional testing or therapy, as delays are no longer caused by preparation of clinical samples, transport, and central laboratory analysis. Tests in a POC format can now be found for many medical disciplines including endocrinology/diabetes, cardiology, nephrology, critical care, fertility, hematology/coagulation, infectious disease and microbiology, and general health screening. Point-of-care testing (POCT) enables health care personnel to perform clinical laboratory testing near the patient. The idea of conventional and POCT laboratory services presiding within a hospital seems contradictory; yet, they are, in fact, complementary: together POCT and central laboratory are important for the optimal functioning of diagnostic processes. They complement each other, provided that a dedicated POCT coordination integrates the quality assurance of POCT into the overall quality management system of the central laboratory. The motivation of the third edition of the POCT book from Luppa/Junker, which is now also available in English, is to explore and describe clinically relevant analytical techniques, organizational concepts for application and future perspectives of POCT. From descriptions of the opportunities that POCT can provide to the limitations that clinician’s must be cautioned about, this book provides an overview of the many aspects that challenge those who choose to implement POCT. Technologies, clinical applications, networking issues and quality regulations are described as well as a survey of future technologies that are on the future horizon. The editors have spent considerable efforts to update the book in general and to highlight the latest developments, e.g., novel POCT applications of nucleic acid testing for the rapid identification of infectious agents. Of particular note is also that a cross-country comparison of POCT quality rules is being described by a team of international experts in this field.

Download or read book Battling Malaria written by Institute of Medicine and published by National Academies Press. This book was released on 2006-07-26 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria is an infectious disease common to several parts of the world, including Africa, northern South America, and Asia. During their service in the military, U.S. active members may be sent to any part of the world, including parts of the world where Malaria is an issue. In Liberia in 2003, for example, there was a 28 percent attack rate in Marines who spent a short time ashore, and half of the 80 Marines affected needed to be evacuated to Germany. This was not only costly to the U.S. military but dangerous as well. To fight against this disease, there exists a Malaria Vaccine program in the U.S. military. However, there exists a variety of potential vaccine targets for the most severe and important form of malaria; malaria from the species Plasmodium falciparum. Issues also arise with the fact that there are three possible stages to create vaccines against-preerythrocytic, blood, or transmission. The Department of Defense (DoD), through the commanding general of the U.S. Army Medical Research and Materiel Command (USAMRMC), requested that the Institute of Medicine (IOM) conduct a programmatic review of the military Plasmodium falciparum malaria vaccine research and development program. There was to be a focus on vaccine against the preerythrocytic and blood stages. The IOM formed a committee of 11 experts with collective expertise in malaria vaccine research, parasite immunology, malarial biology, clinical trials and regulatory affairs, industrial and public-sector vaccine development, biologic products research and development (vaccinology), military research and development programs, tropical medicine, and public health. The committee focused different tasks including determining whether the DoD malaria vaccine research and development program is scientifically sound and able to achieve the vaccine program objectives within specified timelines, recommending how to overcome significant, identified barriers, and identifying major strategic goals and timelines based on the material received and presentations made by the DoD's program representatives. Battling Malaria: Strengthening the U.S. Military Malaria Vaccine Program presents the committee's findings, current malaria vaccines, and recommendations for the development of the U.S. Military vaccine research.
Download or read book Malaria Methods and Protocols written by Denise L. Doolan and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Plasmodium spp. parasite was identified as the causative agent of malaria in 1880, and the mosquito was identified as the vector in 1897. Despite subsequent efforts focused on the epidemiology, cell biology, immunology, molecular biology, and clinical manifestations of malaria and the Plasmodium parasite, there is still no licensed vaccine for the prevention of malaria. Physical barriers (bed nets, window screens) and chemical prevention methods (insecticides and mosquito repellents) intended to interfere with the transmission of the disease are not highly effective, and the profile of resistance of the parasite to chemoprophylactic and chemotherapeutic agents is increasing. The dawn of the new millennium has seen a resurgence of interest in the disease by government and philanthropic organizations, but we are still faced with compl- ities of the parasite, the host, and the vector, and the interactions among them. Malaria Methods and Protocols offers a comprehensive collection of protocols describing conventional and state-of-the-art techniques for the study of malaria, as well as associated theory and potential problems, written by experts in the field. The major themes reflected here include assessing the risk of infection and severity of disease, laboratory models, diagnosis and typing, molecular biology techniques, immunological techniques, cell biology techniques, and field applications.

Download or read book Skin and Arthropod Vectors written by Nathalie Boulanger and published by Academic Press. This book was released on 2018-01-20 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent research on skin immunity and the skin microbiome reveals the complexity of the skin and its importance in the development of immunity against arthropod-borne diseases. In diseases such as malaria, borreliosis, leishmaniasis, trypanosomiasis, etc., the skin interface has been shown as an essential site for pathogens to hide from the immune system, and as a potential site of persistence. Only very few vaccines have been successfully developed so far against these diseases, likely because of an insufficient understanding on the development of skin immunity against pathogens. Skin and Arthropod Vectors expands our knowledge on the role of the skin interface during the transmission of arthropod-borne diseases and particularly its immunity. This work may support researchers who strive for developing more efficient diagnostic tools and vaccines. It also gives scientists and advanced students working in related areas a better insight on how humans and animals are attractive to arthropods to develop better repellents, or to set up transgenic arthropods. Offers the only compilation of research focusing on both the skin interface and arthropod vectors, with contributions from international experts Advances research in the effort toward generating more effective diagnostic tools and vaccines focusing on the skin interface Can also serve as supplemental material for dermatology lectures or specialized lectures on medical entomology and skin immunity
