THIS BOOK HAS BEEN DEVELOPED FROM A SHORT LECTURE COURSE GIVEN to advanced undergraduate students as part of a general introduction to the subject of parasitology for zoologists. The book is written for the undergraduate who has no previous experience of parasitology and little background in either biochemistry or physiology. It is not a long book, and students will have to consult some of the more detailed textbooks in parasitology and physiology to gain a full understanding of the topics considered here. My objective in writing this book is to introduce the breadth of parasite physiology, leaving the reader to obtain a depth of knowledge by his own library research. Each chapter covers a single topic or related topics in physiological parasitology, and the variable length of the chapters reflects the amount of research interest that has been generated over the last few decades. It is to be hoped that by use of this book students will develop an interest in some of the more neglected areas and be stimulated to make good some of the more glaring deficiencies in our current knowledge. I should like to acknowledge with gratitude the assistance of my colleagues Dr 1. Barrett, Dr R. A. Klein, Dr A. W. Pike and Dr R. A.

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.

Parasitic flatworms include Cestodes (tapeworms) and trematodes (flukes, schistosomes, etc) and are the cause of a number of major diseases of medical and veterinary significance. Much recent research has focused on molecular biology and genomics. this book aims to review advances in our understanding of these and related topics such as flatworm biochemistry, immunology and physiology. Where appropriate, comparisons are made between different parasitic flatworms and between parasitic and free-living species. Contributors to the book include leading authorities from Europe, North and South America, and Australia.

Human Parasitology emphasizes the medical aspects of the topic, while incorporating functional morphology, physiology, biochemistry, and immunology to enhance appreciation of the diverse implications of parasitism. Bridging the gap between classical clinical parasitology texts and traditional encyclopaedic treatises, Human Parasitology appeals to students interested not only in the medical aspects of Parasitology but also to those who require a solid foundation in the biology of parasites.
