This introductory undergraduate textbook provides a concise, clear and affordable overview of parasite biology for students and nonspecialists, preparing them for more technical and detailed literature. Using examples from all groups of animal parasites, the text considers the various stages of a parasite's life cycle from finding hosts to surviving within the host. The author discusses the significance of damage caused by parasites and approaches to control, giving the book a well-rounded scope for those new to the subject or desiring a review of key points. A key feature of the book is its comparative rather than systematic approach. Suitable for all introductory parasitology courses in biology, zoology and human and veterinary medicine.
