The author's objective in writing this two-volume set was to present an up-to-date account of the major infections or diseases which are transmitted by snails. He has done this well, and has treated these diseases in much greater detail than is usually done in textbooks of general, medical, or veterinary parasitology.
The emphasis is on parasites of human importance but much useful information is included also on zoonoses where humans are incidential hosts. By far, most of the parasites treated here are digenetic trematodes; a few are metastrongyle nematode parasites of vertebrates, which also use molluscan hosts.
The trematodiases are dealt with in Chapters 1 and 2 of Vol. I, and in Chapters 1 through 15 of Vol. II. Chapter 16 of Vol. II presents information on the nematodiases.
After a brief introduction, Chapter 1 contains a general, but rather detailed, account of the morphology and biology of digenetic trematodes, with light and electron micrographs as well as drawings.
