The larvae of Anisakis, whose adult form lives on sea mammals such as whales, seals, and dolphins, are parasitic upon many species of salt-water fish. When the final host animals eat paratenic hosts, the larvae grow to adulthood in the hosts' stomach. However, when hu mans eat these infested fish, the larvae die instead, causing a disease called anisakiasis. In 1960, in the Netherlands, van Thiel et al. found a worm in the intestinal wall of a patient who had eaten raw herring and had suffered symptoms of acute abdomen. The impact of this report was tremendous among Japanese parasitologists because of the Japanese habit of eating raw fish. In 1964, the Special Research Group from the Ministry of Education was established to investigate the disease, stimulating progress in the study of anisakiasis. Three types of worm, Anisakis simplex larva (previously known as Anisakis larva type I), Anisakis physeteris larva (Anisakis larva type II), and Pseudoterranova decipiens larva type A, are believed to cause anisakiasis. As many as 165 kinds of fish and squid in the seas near Japan are hosts to Anisakis simplex, and 9 species are hosts to Pseudoterranova decipiens larvae. Contra caecum has experimentally been observed to invade the gastrointestinal tract, but no infection by this larva has been reported in humans. A case of infection by Pseudoterranova decipiens type B has been described. In Japan, the name Terranova decipiens (Shiraki 1974) has been adopted instead of Phocanema decipiens (Mozgovoi 1953)."

Parasitic zoonoses, the parasitic diseases transmitted between humans and other vertebrate animals, are widespread. The increasing pace of internationalization changes in diet and easy movement from one part of the world to another has caused parasitic zoonoses to be more prevalent. Consequently, these diseases have become the focus of recent research by parasitologists and pathologists whose work is presented in this book. Included in addition to the pathology of parasitic zoonoses and recent trends in research of imported parasites are the classification of phenotypes of anisakid nematodes, the immunohistopathological diagnostic method, and molecular technology to detect and diagnose parasites. Also included are papers on parasitology and international health and the pathology of cerebral malaria. With 38 color illustrations, this book is an invaluable resource for parasitologists, pathologists, and clinicians.

Cases of intestinal anisakiasis, caused by infestation with "Anisakis simplex" larva, are being increasingly reported in both Europe and the United States. The most information about this affliction, however, comes from Japan, where specialists have greater experience in its diagnosis and treatment. This book is based on approximately 600 cases of intestinal anisakiasis in Japan and gives important new findings on the subject. Specific topics include the changes in infection rates among fish, the clinical manifestation of intestinal anisakiasis, the identification of "Anisakis" larva with genetic techniques, echographic and laparographic findings, and X-ray findings. The discussion of serological diagnosis includes the detection of "Anisakis"-specific IgG and IgE antibodies in patients' sera by using monoclonal antibodies against the larva.
