Vers et virus
Cet ouvrage s'adresse aux informaticiens avec une nouvelle vision du phénomène virus : celle du chasseur et non celle du hacker. Son but n'est pas d'expliquer comment sont conçus les virus, mais comment ils fonctionnent et comment les combattre. L'entrée en matière retrace l'histoire des virus informatiques, histoire fertile en anecdotes et rebondissements. Vient ensuite une déclinaison des différents types de virus avec leurs cibles et leurs attributs. Les virus programmes et les vers sont expliqués très en détail puisque l'auteur présente des visualisations de fichiers en hexadécimal pour faire comprendre aux lecteurs la structure interne des fichiers modernes et la trace qu'y laissent les virus. Viennent ensuite la protection anti-virale dans ses aspects théoriques et méthodologiques, puis les critères de choix d'un bon anti-virus. Cet ouvrage se termine par une analyse de l'évolution de la criminalité informatique et de ses motivations.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
Plant Virus and Viroid Diseases in the Tropics
Around the globe, besides fungal and bacterial diseases, both virus and viroid diseases have acquired greater importance in the realm of plant pathology and call for effective management measures as they are responsible for heavy yield losses and are a matter of vital importance and concern to farmers, horticulturists, gardeners and foresters. Understanding disease epidemiology is of vital importance for formulating viable disease management practices in a given agro-ecosystem. The development and progress of plant disease epidemics are variable from region to region. Epidemiology is not a static process, but rather a dynamic course that varies with a change in the ecology, host, vector and virus systems.
The Coming Plague
After four decades of assuming that the conquest of all infectous diseases was imminent, people on all continents now find themselves besieged by AIDS, drug-resistant tuberculosis, cholera that defies chlorine water treatment, and exotic viruses that can kill in a matter of hours. Based on extensive interviews with leading experts in virology, molecular biology, disease ecology and medicine, as well as field research in sub-Saharan Africa, Western Euope, Central America and the United States, The Coming Plague takes readers from the savannas of eastern Bolivia to the rain forests of northen Zaire on a harrowing, fifty year journey through our battles with the microbes, and tells us what must be done to prevent the coming plague.

Control and Surveillance of Human African Trypanosomiasis
This report provides information about new diagnostic approaches, new therapeutic regimens and better understanding of the distribution of the disease with high-quality mapping. The roles of human and animal reservoirs and the tsetse fly vectors that transmit the parasites are emphasized. The new information has formed the basis for an integrated strategy with which it is hoped that elimination of HAT will be achieved. The report also contains recommendations on the approaches that will lead to elimination of the disease. Human African Tryponosomiasis (HAT) is a disease that afflicts populations in rural Africa, where the tsetse fly vector that transmits the causative trypanosome parasites thrives. There are two forms of HAT: one, known as gambiense HAT, is endemic in West and Central Africa and causes over 95% of current cases; the other, known as rhodesiense HAT, is endemic in East and southern Africa and accounts for the remainder of cases. The presence of parasites in the brain leads to progressive neurological breakdown. Changes to sleep-wake patterns are among the symptoms that characterize the disease, also known as "sleeping sickness". Eventually, patients fall into a coma and die if not treated. Different treatments are available against parasites present in the haemolymphatic system (first stage) and those that have entered the brain (second stage). Currently, lumbar puncture is required to select the appropriate drug.
Ebola and Marburg Viruses
The Ebola and Marburg viruses are a pair of filoviruses that are among the most lethal hemorrhagic viruses on the planet. The authors present a review of past and current research into these pathogens, including 12 papers addressing the structure of the viral proteins; genomic replication; molecular mechanisms of entry; pathogenesis in nonhuman primates, guinea pigs, and mice; virus modulation of innate immunity; and cellular and molecular mechanisms of Ebola pathogenicity and related approaches to vaccine development.
The Changing HIV AIDS Landscape
HIV/AIDS reverses life expectancy gains, erodes productivity, consumes savings and dilutes growth efforts, threatening the realization of the Millennium Development Goals (MDGs) in Africa.The report is the result of an extensive analytical and consultative process begun in 2006, that engaged more than 1,000 people from over 30 countries and many institutions mostly in Africa, as well as UN agencies, multilateral and bilateral donors, and foundations. The report reaffirms the Bank's commitment to combating HIV/AIDS in Africa, moving from its initial emergency response to the next phase, including the goal to provide at least US $250 million annually and to create an Africa HIV/AIDS Incentive Fund to enhance the evidence base, promote the multisectoral response and provide technical support, analysis and policy advice to countries.
