This book has been planned to incorporate new discoveries and concepts in immunoparasitology as well as the ever-growing areas of host-parasite relationship and cross-regulated among parasite development the immune system and other host system, such as the metabolism.

All the authors in this book have made invaluable contributions to the knowledge of the interaction between parasites and the immune response with great expertise, so that each chapter is an actualized and current review of a topic in which authors are leaders in the field and of course are directly involved in laboratory and field experimentation.
