This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaria is a deadly disease that causes nearly one million deaths each year. Understanding the demographic history of the malaria parasite Plasmodium falciparum and the genetic basis of its adaptations to antimalarial treatments and the human immune system is important for developing methods to control and eradicate malaria. To study the long-term demographic history and recent effective size of the population in order to identify genes under selection more efficiently and predict the effectiveness of selection, in Chapter 2 we sequenced the complete genomes of 25 cultured P. falciparum isolates from Senegal. In addition, in Chapter 3 we estimated temporal allele frequencies in 24 loci among 528 strains from the same population across six years. Based on genetic diversity of the genome sequences, we estimate the long-term effective population size to be approximately 100,000, and a major population expansion of the parasite population approximately 20,000-40,000 years ago. Based on temporal changes in allele frequencies, however, the recent effective size is estimated to be less than 100 from 2007-2011. The discrepancy may reflect recent aggressive efforts to control malaria in Senegal or migration between populations.
Download or read book The Malaria Genome Projects written by Irwin W. Sherman and published by World Scientific. This book was released on 2012 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: The year 2012 marks the tenth anniversary of the announcement of the genome sequence of the human malaria parasite Plasmodium falciparum and that of its mosquito vector Anopheles. The genome sequences were a result of the Plasmodium falciparum Genome Project. This book covers in detail the biology of malaria parasites and the mosquitoes that transmit the disease, how the Genome Project came into being, the people who created it, and the cadre of scientists who are attempting to see the promise of the Project realized. The promise was: a more complete understanding of the genes of the parasite (and its vector) would provide a rational basis for the development of antimalarial drugs and vaccines, allow a better understanding of the regulation of the complex life cycle in the red blood and liver cells of the human, identify the genes the parasite uses to thwart the host immune response and the ways in which the parasite evades cure by drug treatments, as well as leading to more effective measures of control transmission. The hope was that cracking the genetic code of Plasmodium and Anopheles would reveal the biochemical Achilles heel of the parasite and its vector, leading to the development of novel drugs and better methods of control, and by finding the targets of protective immunity could result in the manufacture of effective vaccines. Through a historic approach, this book will allow for those new to the field, or those with insufficient background in the sciences, to have an easier entry point. Even scientists already working in the field may better appreciate how discoveries made in the past can impact the direction of future research.

Download or read book Malaria Parasites written by Andrew P. Waters and published by Caister Academic Press Limited. This book was released on 2004 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The completion of the Plasmodium falciparum genome sequence in late 2002 heralded a new era in malaria research. The search began in earnest for new drugs and vaccines to combat malaria, a disease which afflicts up to 500 million people worldwide and is responsible for the deaths of more than one million people each year. The new genomic data is aiding a greater understanding of the living parasite and its interaction with the insect vector and human host. In this book internationally renowned experts provide up-to-date reviews of the most important aspects of post-genomic malaria research. Topics covered include: the P. falciparum genome and model parasites, bioinformatics and genome databases, microsatellite analysis, analysis of chromosome structure, cell cycle to RNA polymerase I and II mediated gene expression, role of the nuclear genome, the parasite surface and cell biology, and much more. The book is essential to all researchers working in this highly topical field and is recommended reading for scientists in other areas of biology and medicine.

Available in PDF, EPUB and Kindle. Book excerpt: Parasitic protozoan infections of the red blood cell are among the most widespread and devastating pathogens of vertebrates. In humans, two genera of pathogens cause disease: the Plasmodia, which cause malaria, and the Babesia, which cause babesiosis. In this thesis, we apply the tools of whole genome sequencing and evolutionary genetics to study factors contributing to the spread of these pathogens: in P. falciparum, the acquisition of multiple drug resistance, and in B. microti the development of azithromycin resistance and the population genetics of emergence.

Download or read book Evolution of Multigene Families and Single Copy Genes in Plasmodium Spp written by Andreina I. Castillo Siri and published by . This book was released on 2016 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complex life cycle and widespread range of infection of Plasmodium parasites, the causal agent of malaria in humans, makes them the perfect organism for the study of various evolutionary mechanisms. In particular, multigene families are considered one of the main sources for genome adaptability and innovation. Within Plasmodium, numerous species- and clade-specific multigene families have major functions in the development and maintenance of infection. Nonetheless, while the evolutionary mechanisms predominant on many species- and clade-specific multigene families have been previously studied, there are far less studies dedicated to analyzing genus common multigene families (GCMFs). I studied the patterns of natural selection and recombination in 90 GCMFs with diverse numbers of gene gain/loss events. I found that the majority of GCMFs are formed by duplications events that predate speciation of mammal Plasmodium species, with many paralogs being neutrally maintained thereafter. In general, multigene families involved in immune evasion and host cell invasion commonly showed signs of positive selection and species-specific gain/loss events; particularly, on Plasmodium species is the simian and rodent clades. A particular multigene family: the merozoite surface protein-7 (msp7) family, is found in all Plasmodium species and has functions related to the erythrocyte invasion. Within Plasmodium vivax, differences in the number of paralogs in this multigene family has been previously explained, at least in part, as potential adaptations to the human host. To investigate this I studied msp7 orthologs in closely related non-human primate parasites where homology was evident. I also estimated paralogs evolutionary history and genetic polymorphism. The emerging patterns where compared with those of Plasmodium falciparum. I found that the evolution of the msp7 multigene family is consistent with a Birth-and-Death model where duplications, pseudogenization and gene lost events are common. In order to study additional aspects in the evolution of Plasmodium, I evaluated the trends of long term and short term evolution and the putative effects of vertebrate- hosts immune pressure of gametocytes across various Plasmodium species. Gametocytes, represent the only sexual stage within the Plasmodium life cycle, and are also the transition stages from the vertebrate to the mosquito vector. I found that, while male and female gametocytes showed different levels of immunogenicity, signs of positive selection were not entirely related to the location and presence of immune epitope regions. Overall, these studies further highlight the complex evolutionary patterns observed in Plasmodium.

Download or read book Variation and Evolution in Plants and Microorganisms written by National Academy of Sciences and published by National Academies Press. This book was released on 2000-11-11 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The present book is intended as a progress report on [the] synthetic approach to evolution as it applies to the plant kingdom." With this simple statement, G. Ledyard Stebbins formulated the objectives of Variation and Evolution in Plants, published in 1950, setting forth for plants what became known as the "synthetic theory of evolution" or "the modern synthesis." The pervading conceit of the book was the molding of Darwin's evolution by natural selection within the framework of rapidly advancing genetic knowledge. At the time, Variation and Evolution in Plants significantly extended the scope of the science of plants. Plants, with their unique genetic, physiological, and evolutionary features, had all but been left completely out of the synthesis until that point. Fifty years later, the National Academy of Sciences convened a colloquium to update the advances made by Stebbins. This collection of 17 papers marks the 50th anniversary of the publication of Stebbins' classic. Organized into five sections, the book covers: early evolution and the origin of cells, virus and bacterial models, protoctist models, population variation, and trends and patterns in plant evolution.
