Host Parasite Relations Between Man And His Intestinal Protozoa

This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.

Discover how the application of novel multidisciplinary, integrative approaches and technologies are dramatically changing our understanding of the pathogenesis of infectious diseases and their treatments. Each article presents the state of the science, with a strong emphasis on new and emerging medical applications. The Encyclopedia of Infectious Diseases is organized into five parts. The first part examines current threats such as AIDS, malaria, SARS, and influenza. The second part addresses the evolution of pathogens and the relationship between human genetic diversity and the spread of infectious diseases. The next two parts highlight the most promising uses of molecular identification, vector control, satellite detection, surveillance, modeling, and high-throughput technologies. The final part explores specialized topics of current concern, including bioterrorism, world market and infectious diseases, and antibiotics for public health. Each article is written by one or more leading experts in the field of infectious diseases. These experts place all the latest findings from various disciplines in context, helping readers understand what is currently known, what the next generation of breakthroughs is likely to be, and where more research is needed. Several features facilitate research and deepen readers' understanding of infectious diseases: Illustrations help readers understand the pathogenesis and diagnosis of infectious diseases Lists of Web resources serve as a gateway to important research centers, government agencies, and other sources of information from around the world Information boxes highlight basic principles and specialized terminology International contributions offer perspectives on how infectious diseases are viewed by different cultures A special chapter discusses the representation of infectious diseases in art With its multidisciplinary approach, this encyclopedia helps point researchers in new promising directions and helps health professionals better understand the nature and treatment of infectious diseases.

Reviews key areas in ecological, medical and molecular parasitology Features essays from some of the world's leading parasitologists Each topic is set in context by featuring a key paper from the Journal of Paraistology over the past 100 years

Increasing wisdom and ingenuity are required if we are to master our environment and cope with the myriad of organisms that affect our existence. Not the least of these organisms are the parasites and pathogens which can be found in all animals. The ecological implications of parasitism are obvious, and the interrelationships among different organisms within the same host are fascinating, but more knowledge and understanding are needed. The symposium are held to stimulate discussion of the significance of ecological problems presented by parasites and to develop means of attacking some of these problems. The diversity of parasitism from protozoa to anthropods was emphasized and the speakers and topics were selected to interest those in various biological disciplines and professions. Organized by the Department of Parasitology in the School of Hygiene of the University of Toronto, and held at Toronto in February 1970, the symposium was an unqualified success. The enthusiastic interest, indicated by the attendance of over three hundred people from seven countries, and numerous requests for copies of the proceedings led to the publication in this volume of the twelve papers presented at the symposium. The opening remarks of the leader of the discussion which follow each paper have been included and a complete bibliography is provided for each topic. The contributors are leading specialists in their fields; their papers present the results of the most recent research and assemble and review the scattered literature on each topic. The text is illustrated throughout with diagrams and photographs. Parasitism and associated phenomena are excellent examples of problems requiring the interdisciplinary approach taken by the symposium. The results of such an approach are useful in a wide variety of disciplines: microbiology, invertebrate zoology, entomology, and tropical medicine, as well as parasitology.
