Book Description
Human schistosomiasis is a disease with a rich and well-documented past, and every expectation of an unfortunately long future. These infections were known to the ancient Egyptians and their transmission shows little evidence of slowing down, globally. The good news is that field applicable, and increasingly affordable, chemotherapy has been available for almost 25 years. Using chemotherapy and other means of control, some countries have decreased transmission and made excellent headway against morbidity. The bad news is that the public health problems caused by schistosomiasis are still with us, with the estimated number of cases of schistosomiasis, while shifting geographically, remaining approximately 200 million for the last 30 years. In fact, with the development of field usable ultrasound technology and meta-analyses performed on existing data, there is a new appreciation for the extent of non-lethal morbidity associated with these infections. While the percentage of individuals with severe hepatosplenic disease remains below 10%, recent reassessments of morbidity associated with schistosomiasis indicate that the prevelance of symptoms and the cost in diability-adjusted life years is much greater than was previously, commonly appreciated (Van der Werf, M. J. , et al. 2003, Acta Tropica 86:125-139; Charles H. King, personnel communication). Strong impetus for addressing these issues is provided by the World Health Assembly’s recently passed Resolution 54. 19, which calls for efforts to reduce morbidity caused by schistosomiasis and soil-transmitted helminths in school-aged children, largely through chemotherapy campaigns.

Book Description
The study of parasites and their interactions with hosts continues to represent a challenging area of modern biology. The availability of new techniques and instrumentation, coupled with the development of daring new hypotheses and concepts, has paved the way for the dramatic evolution of parasitology from a static descriptive endeavor to a dynamic one based on biochemistry, immunology, molecular biology, and modern cell biology. Studies of this nature obviously fall within the domain of pathobiology. Consequently, when the contributions included in this volume of Comparative PathobioZogy were offered to this series. after critical review, we welcomed the opportunity to make them available to the scientific community. The contributions included herein represent presentations delivered before enthusiastic audiences at three different symposia, all held in 1983. The first, entitled "Some Aspects of Modern Parasitology", was organized by Dr. Gary E. Rodrick of the University of South Florida and myself on behalf of the American Society of Zoologists. The chapters by C. E. Carter and B. M. Wickwire. B. J. Bogitsh, and W. M. Kemp were originally presented at that symposium. The second symposium. organized by Dr. G. Balouet of the Faculte de Medecine, Brest, France, and myself on behalf,of the Society for Invertebrate Pathology, was entitled "Cellular Reactions in Invertebrates." The chapters by G. Balouet and M. Poder and M. Brehelin were originally presented at this symposium.

Book Description
Protozoan and helminth parasites infect animals and humans and cause debilitating pathologies that cause a variety of morbidities and deaths worldwide. The ability of parasites to establish infection and cause disease in mammalian hosts is a result of a series of intricate mechanisms evolved by parasitic species to confront and evade the host's defensive responses, along with the ability to use the host’s metabolic and catabolic processes and host cellular organelles to their benefit. For instance, parasites may have predilection sites in the host that are not accessible to immune effector molecules and mechanisms, may acquire host-derived "masking" molecules, can vary their surface molecules, and can produce molecules that block or misguide the host immune responses. The host's interactions with the parasite, on the other hand, are critical for the initiation and induction of host signaling events that are critical in mounting formidable defensive immune responses against the invading parasite. Therefore, the ability of a parasite to successfully establish infection and cause disease largely depends on its interaction with the host and the ability of the host to mount successful and effective resistance. Thus, studying host-parasite interactions and cross-talks is critical for understanding parasite infection and adaptation mechanisms within the host, as well as for developing strategies for effective prevention and control of parasitic infections in humans and animals. The topic will cover a wide spectrum of parasitic protozoa and helminths and provide an opportunity to share new molecular and translational advances in parasitic infections and diseases.

Book Description
Human schistosomes (blood flukes) are digenetic trematodes that spend the adult part of their life cycle in humans and a further part in aquatic snails. Despite advances in chemotherapy, schistosomiasis is still a significant infection in the populations of several countries in the tropics. This book replaces a previous volume Schistosomiasis: Epidemiology, Treatment and Control (Heinemann, 1982) by Jordan and Webbe. All chapters have been rewritten by internationally renowned workers. Ultrasound, expected to aid identification of early disease in the field and increase our understanding of its evolution, is discussed in a new chapter. Others, each with an extensive bibliography, review the parasites and their snail intermediate hosts, epidemiology, clinical manifestations and pathology, diagnosis, immunology, drugs and patient management and control. Limitations of the role of chemotherapy in morbidity control are discussed and the need for flexibility in control interventions in the varied epidemiological situations is stressed. An interdisciplinary approach may be necessary to reduce transmission by appropriate measures against the snail intermediate host, and to implement public health measures, including the provision of safe water (with many other medical and social benefits) and health education. This comprehensive volume is for public health workers involved in the prevention and control of the disease, for physicians, and for students and teachers of many disciplines. It also provides a reference book for health planners, social anthropologists, health educators, water and sanitary engineers and others engaged in improving health in the tropics. Physicians in temperate countries will also find it a useful reference book as schistosomiasis, often acute, is being diagnosed more frequently in those returning from holidays in endemic areas.

Book Description
In Parasitism, Claude Combes explores the fascinating adaptations parasites have developed through their intimate interactions with their hosts. He begins with the biology of parasites—their life cycles, habitats, and different types of associations with their hosts. Next he discusses genetic interactions between hosts and parasites, and he ends with a section on the community ecology of parasites and their role in the evolution of their hosts. Throughout the book Combes enlivens his discussion with a wealth of concrete examples of host-parasite interactions.
