This volume provides a reflective summary of research in parasitology in the late 20th Century combined with a vision of the major challenges and potential successes in the 21st Century. It has been compiled from selected papers presented at the Eighth International Congress of Parasitology. A wide variety of topics are covered including medical, veterinary, and plant parasitology, by contributors from many different countries. Chapters within the book consider current research on the biology of parasites, and new strategies in the transmission and control of parasitic diseases. This book represents an invaluable resource for all parasitologists. Not only is it an up- to-date summary of research, but it is also a thought provoking look at the future.
