Download or read book Towards Malaria Elimination written by Sylvie Manguin and published by BoD – Books on Demand. This book was released on 2018-07-18 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Towards Malaria Elimination - A Leap Forward was started to mark the occasion for renewed commitment to end malaria transmission for good (the WHO's call for "Malaria Free World" by 2030). This book is dedicated for the benefit of researchers, scientists, program and policy managers, students and anyone interested in malaria and other mosquito-borne diseases with the goal of sharing recent information on success stories, innovative control approaches and challenges in different regions of the world. Some main issues that emerged included multidrug-resistant malaria and pandemic risk, vaccines, cross-border malaria, asymptomatic parasite reservoir, the threat of Plasmodium vivax and Plasmodium knowlesi, insecticide resistance in Anopheles vectors and outdoor malaria transmission. This book is one little step forward to bring together in 17 chapters the experiences of malaria-expert researchers from five continents to present updated information on disease epidemiology and control at the national/regional level, highlighting the constraints, challenges, accomplishments and prospects of malaria elimination.

Download or read book Genetic Control of Malaria and Dengue written by Zach N. Adelman and published by Academic Press. This book was released on 2015-10-15 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic Control of Malaria and Dengue focuses on the knowledge, technology, regulation and ethics of using genetically modified mosquitoes to interrupt the transmission of important vector-borne diseases including Malaria. It contains coverage of the current state of knowledge of vector-borne diseases and how they are currently controlled; vaccine, drug and insecticide development; various strategies for altering the genome of mosquitoes in beneficial ways; and the regulatory, ethical and social environment concerning these strategies. For more than five decades, the prospect of using genetically-modified mosquitoes to control vector-borne disease transmission has been a purely hypothetical scenario. We simply did not have the technology or basic knowledge to be able to do it. With the explosion of field trials and potential interventions in development, Genetic Control of Malaria and Dengue provides a comprehensive overview of research in genetics, microbiology, virology, and ecology involved in the development and implementation of genetic modification programs for virus and disease control. This book is meant to provide a practical guide to researchers, regulators and the general public about how this technology actually works, how it can be improved, and what is still unknown. Includes coverage of vectorial capacity, critical to understanding vector-borne disease transmission Provides a summary of the concepts of both population suppression and population replacement Contains pivotal coverage of ethical and ecological ramifications of genetics-based control strategies

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical control of mosquito vectors, via indoor residual spraying or insecticide treated bed nets, is an integral component of malaria control strategies. Limited availability of insecticides licensed for public health and the rapid development of resistance in mosquito populations to these insecticides, in particular to some pyrethroids, may compromise vector control efforts. With the exception of mutations in the insecticide target sites, relatively little is known about the genetics of pyrethroid resistance in malaria vectors. In some populations candidate effector genes, e.g. cyp6p3 or cyp6m2 in An. gambiae s.s. from Akron, Benin, have been identified as being over expressed in resistant strains but the underlying mechanisms responsible for the increased expression remain unknown. In this study, a combination of quantitative PCR, genetic mapping and microarray tools were used to investigate the mechanisms responsible for pyrethroid resistance in two African major malaria vectors, Anopheles gambiae and An. arabiensis. The current work was unable to confirm an association of these known candidates in either a laboratory colony established from Akron or in recent field caught material. Therefore a genetic mapping approach was adopted using field collected mated females to generate F2 isofemale lines. A major QTL on chromosome 3R was identified which coincides with a genomic region previously implicated in pyrethroid resistance in East African populations. This is the first genetic mapping of insecticide resistance using natural out-bred populations of Anopheles and the advantages and limitations of this approach are discussed. In a second experiment, genetic loci involved in permethrin resistance in An. arabiensis were mapped by establishing genetic crosses between a permethrin resistant strain from Chad and a susceptible strain from Mozambique. A single QTL on chromosome 2R was identified in the F2 progeny that accounts for ~24% of the phenotypic variance. This QTL coincides with a large cluster of detoxification genes. Pyrethroid resistance is not associated with target-site mutations in this population. Finally, microarrays were used to identify genes differentially expressed between a backcross population, generated by crossing the F1 population from the resistant Chad strain and the susceptible Mozambique strain of An. arabiensis back to the parental resistant strain, with the susceptible strain. A number of candidate genes were identified, including the P450 genes cyp4h24 and cyp9j5, but neither of these were located within the boundaries of the QTL on 2R. These findings support the presence of metabolic resistance in this population and fine mapping of the identified QTL as well as further investigation of the microarray hits is warranted.
Download or read book Gene Drives on the Horizon written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.

Download or read book Pesticide Resistance in Arthropods written by Richard Roush and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bruce E. Tabashnik and Richard T. Roush Pesticide resistance is an increasingly urgent worldwide problem. Resistance to one or more pesticides has been documented in more than 440 species of insects and mites. Resistance in vectors of human dise8se, particularly malaria-transmit ting mosquitoes, is a serious threat to public health in many nations. Agricultural productivity is jeopardized because of widespread resistance in crop and livestock pests. Serious resistance problems are also evident in pests of the urban environ ment, most notably cockroaches. Better understanding of pesticide resistance is needed to devise techniques for managing resistance (Le. , slowing, preventing, or reversing development of resistance in pests and promoting it in beneficial natural enemies). At the same time, resistance is a dramatic example of evolution. Knowledge of resistance can thus provide fundamental insights into evolution, genetics, physiology, and ecology. Resistance management can help to reduce the harmful effects of pesticides by decreasing rates of pesticide use and prolonging the efficacy of environmentally safe pesticides. In response to resistance problems, the concentration or frequency of pesticide applications is often increased. Effective resistance management would reduce this type of increased pesticide use. Improved monitoring of resis tance would also decrease the number of ineffective pesticide applications that are made when a resistance problem exists but has not been diagnosed. Resistance often leads to replacement of one pesticide with another that is more expensive and less compatible with alternative controls.
