Parasite invasion

"The subject of this symposium has long held fascination for on it depends the evolution of parasitism: it is discussed here at all levels, from the 'micro'-invasion by viruses to the 'macro'-passage of helminths through host tissues. All stages in the life-cycle are considered wherever possible and the contributions presented in this volume provide parasitologists with a stimulating and up-to-date review of the subject"--Back cover.
