This book tackles a number of different perspectives concerning the parasitic helminth Ascaris, both in animals and in humans and the disease known as ascariasis. It seeks to identify interesting, exciting and novel aspects, which will interest readers from a broad range of disciplines.Over a quarter of the world's population are infected with the human roundworm, and the equivalent in pigs is equally ubiquitous. Both contribute to insidious and chronic nutritional morbidity, and this has been quantified, in humans, as disability adjusted life years approximating 10.5 million. Ascaris larvae develop in host parenteral tissues, and the resultant pathology has been condemnation. Ascariasis, despite its staggering global prevalence and the sheer numbers of people it infects, remains a classic neglected disease. However, renewed interest in the consequences of early infection with worms from the perspective of immune modulation, co-infections and the development of allergy further enhances the relevance of these parasites. - Brings together a wide range of topics and approaches and recent, comprehensive and progressive research concerning the neglected parasite Ascaris - Provides a blueprint of how a single parasite entity can stimulate interest in basic biology, clinical science, veterinary science, public health and epidemiology - Presents a wealth of new insights given that a book on this parasite has not been published for over 20 years - 16 chapters from a range of top authors from around the world

In a unique, visual approach to the depiction of parasite life cycles, this detailed atlas presents a clear, concise, and complete overview of the parasite/human host interrelationship. 75 life cycles include all the major protozoan and helminth pathogens of man with new and updated information on several organisms. The illustrations follow the route of infection from point of entry, through the developmental stages, to completion of the cycle as the parasite reinfects the next host. Precise biological anatomical and medical depiction provides reinforcement. Distinguished by its organization, continuity, and accuracy, this comprehensive work will be a valuable reference for students, clinicians and others interested in the field of parasitology.

This textbook will provide a systematic comprehension of the various medically important human parasites; their distribution, habitat, morphology and life cycle, pathogenesis and clinical features, laboratory diagnosis, treatment, prevention and control. The main emphasis is on the protozoan and helminthic diseases, also medical entomology covering vectors relevant to these diseases. The book aims to promote an easy yet comprehensive way of learning parasitology. It attempts to break down the complexity of medical parasitology into parts that are easy to understand yet integrating the essential information of parasitic infections. The integration of knowledge of parasites will be achieved through student friendly illustrations, inclusion of a collection of recent case reports, examples of test questions and scenarios, and the images of human parasites. Essentially, it provides a “one-stop learning package” for medical parasitology.

The revised and updated second edition of Water and Sanitation Related Diseases and the Changing Environment offers an interdisciplinary guide to the conditions responsible for water and sanitation related diseases. The authors discuss the pathogens, vectors, and their biology, morbidity and mortality that result from a lack of safe water and sanitation. The text also explores the distribution of these diseases and the conditions that must be met to reduce or eradicate them. The text includes contributions from authorities from the fields of climate change, epidemiology, environmental health, environmental engineering, global health, medicine, medical anthropology, nutrition, population, and public health. Covers the causes of individual diseases with basic information about the diseases and data on the distribution, prevalence, and incidence as well as interconnected factors such as environmental factors. The authors cover access to and maintenance of clean water, and guidelines for the safe use of wastewater, excreta, and grey water, plus examples of solutions. Written for students, and professionals in infectious disease, public health and medicine, chemical and environmental engineering, and international affairs, the second edition of Water and Sanitation Related Diseases and the Changing Environment isa comprehensive resource to the conditions responsible for water and sanitation related diseases.

This manual has been developed to provide those who are involved in the diagnosis of parasitic diseases with a resource that encompasses the basic technology required for detection of parasites and identification of their diagnostic stages in feces, blood, other body fluids, and tissues. In addition to the technical procedures described, a summary of the morphologic charateristics that are used in the identification of protozoa and helminths is provided as well as line drawings, original color representations of the stages of the human malarial parasites, and photomicrographs of the diagnostic stages of many parasites.

We first discussed the possibility of organizing a symposium on helminth communities in June, 1986. At that time, we were engaged in writing a joint paper on potential structuring mechanisms in helminth communities; we disagreed on a number of issues. We felt the reason for such debate was because the discipline was in a great state of flux, with many new concepts and approaches being introduced with increasing frequency. After consider able discussion about the need, scope and the inevitable limitations of such a symposium, we decided that the time was ripe to bring other ecologists, engaged in similar research, face-to-face. There were many individuals from whom to choose; we selected those who were actively publishing on helminth communities or those who had expertise in areas which we felt were particularly appropriate. We compiled a list of potential participants, contacted them and received unanimous support to organize such a symposium. Our intent was to cover several broad areas, fully recognizing that breadth negates depth (at least with a publisher's limitation on the number of pages). We felt it important to consider patterns amongst different kinds of hosts because this is where we had disagreed among ourselves.

Homo sapiens rank among the most parasitized of all animals. In part this is because we know so much about all aspects of the biology of our species, but in addition, our varied habitat and diet and our global distribution exposes us to more infections than any other species. Whereas some familiar parasitic infections are responsible for much human disease and suffering, the great majority are rare or obscure forms ignored by all but the most comprehensive texts. The Parasites of Homo sapiens: An Annotated checklist of the Protozoa, Helminths and Arthropods for Which We Are Home, 2nd Edition presents a comprehensive listing of them all. Closely following the pattern of the first edition, this new edition incorporates a wealth of further information and data from the most recently published research findings. An indispensable guide for all parasitologists, it presents a comprehensive checklist of all animals naturally parasitic in or on the human body. Each parasite listed includes a complete summary of its characteristics. The structure of each entry includes: The scientific name of the parasite Synonyms for scientific names Status of reported human cases Geographical distribution and abundance Parasite habitat on humans Hosts Transmission mechanisms Human risk factors Indication of host-specificity status

Written by internationally respected experts, Handbook of Human Helminthiasis provides information essential in the development of an integrated approach to the prevention, control and treatment of disease caused by endoparasitic helminths. The text is divided into sections dealing with the main groups of helminth infections and the diseases they i
