American Trypanosomiasis


Book Description

Chagas disease causes severe socioeconomic impact and a high medical cost in Latin America. WHO and the World Bank consider Chagas disease as the fourth most transmittable disease to have a major impact on public health in Latin America: 120 million persons are potentially exposed, 16 to 18 million of whom are presently infected, causing 45,000 to 50,000 deaths per year. It has been calculated that approximately 2.4 million potential working years are lost because of incapacity and mortality due to the disease, for an annual cost estimated at 20 billion Euros. American Trypanosomiasis provides a comprehensive overview of Chagas disease and discusses the latest discoveries concerning the three elements that compose the transmission chain of the disease: - The host: human and mammalian reservoirs - The insect vectors: domestic and sylvatic vectors - The causative parasite: Trypanosoma cruzi - Informs and updates on all the latest developments in the field - Contributions from leading authorities and industry experts




Progress in Human African Trypanosomiasis, Sleeping Sickness


Book Description

Human African Trypaniosomiasis (HAT) or sleeping sickness is an old disease to be now considered as reemergent. HAT is endemic in 36 sub-Saharan African countries, in areas where tsetse flies are found. The public health importance of HAT is underestimated, but the disease causes severe social disruption in many rural areas. Along the past fifteen years, numerous studies were made, and now, the mechanisms involved in the disease pathogenesis and in the characteristics of sleep-wake disruption become to be better understood. But, since 50 years, when current drugs were introduced, problems regarding HAT chemotherapy have not been solved. Nevertheless, in-depth studies about trypanosome metabolism have permitted to discover new drug targets. Written by specialists who are very experienced in their respective fields, the contributions provide an indispensable tool for practitioners and scientists.

Uveitis


Book Description

Focusing solely on uveitis care, this quick reference guide will provide a compiled and easy to navigate differential diagnosis – making an often daunting task for clinicians easier, quicker, and more accurate by using a concise outline format to list the most critical aspects of a disease entity. Uveitis: A Quick Guide to Essential Diagnosis opens with a Diagnosis Flowchart, so that the reader can select the most probable diagnoses based on patient’s history and exam. From there the reader can then quickly turn to the corresponding chapter to learn about the most critical aspects of the disease entity: epidemiology, characteristic exam and imaging findings, prognostic factors, and treatment options. This book is written for ophthalmic care providers including general ophthalmologists, subspecialists, fellows, residents and optometrists and features research and contributions from institutions that are global leaders in uveitis care.




Tsetse Biology and Ecology


Book Description

Domestic livestock in Africa are of importance not only as a source of milk and meat but also as a source of animal traction enabling farmers to cultivate larger areas, with crops providing the staple foods. Trypanosomosis, a parasitic disease transmitted cyclically by the tsetse fly (Glossina spp.), is arguably still the main constraint to livestock production on the continent, preventing full use of the land to feed the rapidly increasing human population. Sleeping sickness, the disease caused in humans by species of Trypanosoma, is an important and neglected disease posing a threat to millions of people in tsetse-infested areas. Often wrongly thought of as a disease of the past, the prevalence of human sleeping sickness is increasing in many areas. Although alternative methods to control the disease are being investigated, such as immunological approaches, use of chemotherapy or exploitation of the trypanotolerance trait, it is only control or eradication of the tsetse fly vector which will remove the threat of the disease rather than providing a better means of "living" with it. As a result of the economic impact of tsetse-transmitted Trypanosomosis, a large amount of research literature has been produced. This book provides a comprehensive review of this literature. The text is divided into four parts: tsetse biology and ecology, epidemiology, vector control and control of trypanosomosis. The book is invaluable for medical and veterinary entomologists, parasitologists and epidemiologists.




Human Emerging and Re-emerging Infections


Book Description

Emerging and re-emerging pathogens pose several challenges to diagnosis, treatment, and public health surveillance, primarily because pathogen identification is a difficult and time-consuming process due to the “novel” nature of the agent. Proper identification requires a wide array of techniques, but the significance of these diagnostics is anticipated to increase with advances in newer molecular and nanobiotechnological interventions and health information technology. Human Emerging and Re-emerging Infections covers the epidemiology, pathogenesis, diagnostics, clinical features, and public health risks posed by new viral and microbial infections. The book includes detailed coverage on the molecular mechanisms of pathogenesis, development of various diagnostic tools, diagnostic assays and their limitations, key research priorities, and new technologies in infection diagnostics. Volume 1 addresses viral and parasitic infections, while volume 2 delves into bacterial and mycotic infections. Human Emerging and Re-emerging Infections is an invaluable resource for researchers in parasitologists, microbiology, Immunology, neurology and virology, as well as clinicians and students interested in understanding the current knowledge and future directions of infectious diseases.




Combating and Controlling Nagana and Tick-Borne Diseases in Livestock


Book Description

African animal trypanosomosis (AAT), also called nagana, is a trans-boundary disease that has had an immense impact on cattle and is ranked among the top global cattle diseases. This and tick-borne diseases have caused major obstacles to sustainable livestock-based agricultural production and food security and are important factors in underdevelopment. Due to decreasing efficacy of available drugs, widespread trypanosome resistance, and the difficulty of sustaining other control measures, there is a need for alternative sustainable strategies to reduce the impact these diseases have on livestock. Combating and Controlling Nagana and Tick-Borne Diseases in Livestock provides the latest empirical research findings on the effects of African animal trypanosomiasis (nagana) and tick-borne disease infection in livestock, their impact on farmer livelihoods, and the measures that can be undertaken to mitigate negative effects and reduce the number of infections. While highlighting topic areas such as disease history and transmission, treatments, and the economic impacts, this book is essential for farmers, animal health and animal production professionals and practitioners, non-government organizations, researchers, academicians, and students working in fields that include but are not limited to agriculture, livestock production, environmental science, veterinary medicine, veterinary pathology, and epidemiology.




Diseases of Cattle in the Tropics


Book Description

Most of the future increase in livestock production is expected to occur in the tropical and subtropical regions of the world. Cattle are the most numerous of the ruminant species in the tropics and provide the largest quantity of animal food products. More than one-third of the world's cattle are found in the tropics. Disease is the major factor which prohibits full utilization of these regions for cattle production. Various infectious and transmissible viral, rick ettsial, bacterial, and particularly protozoan and helminthic diseases, are widespread in the tropics and exert a heavy toll on the existing cattle industry there. This uncontrolled disease situation also discourages investment in cattle industries by private and government sectors. In Africa alone, it is estimated that 125 million head of cattle could be accommodated in the tropical rainbelt if the disease and other animal husbandry factors could be resolved. The potential of efficient cattle production under more favorable conditions prompted various international agencies to establish a multi million dollar International Laboratory for Research in Animal Diseases (ILRAD) in Nairobi, Kenya, Africa. In South America, principal sites for raising cattle are shifting to the savannah lands because the more fertile soils are being used for crop produc tion, however, in the savannahs also, disease remains the most powerful deterrent in implementing the cattle industry.




The Biology of Trypanosomes


Book Description

African and South American trypanosomiases are notable features of clinical and veterinary practice in their respective endemic areas and, as such, are of considerable economic importance. Scientifically, however, their importance ex tends beyond their clinical significance, as the trypano somes are intriguing and easily manipulated models for the study of the control of gene expression, membrane chemistry, proliferation and differentiation. It is clear from the scientific press that the rate of advance has "hotted" up in these areas of trypanosome research over the past 5 years and so a single-topic volume within the scope of the present series seemed timely. As ever, the final admix ture of review topics was a compromise between what was appropriate and what was available - fortunately with the former in vast excess. I should like to highlight two omissions, made for en tirely different reasons. The first is a detailed treatment of the molecular biology of the variant surface glycopro teins of the African trypanosomes (in particular Trypano soma brucei and T. equiperdum). This topic has been the subject of several reviews, for example, BORST and CROSS (1982)1 and TURNER (1982)2, and so was excluded from the present volume. The second omission is a review of the first-class work on genetic recombination from the group of Dr. Leo Jenni at the Schweizerisches Tropeninsti tut, Basel. This group has used isoenzyme markers to show that T.
