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 held in October 1994. Speakers came from all over the world and a wide variety of topics were covered including medical, veterinary, and plant parasitology. Papers within the book consider current research on the biology of parasites, and new strategies in the transmission and control of parasitic diseases.
