Acanthocephalans of the genus Corynosoma are known as intestinal parasites, mainly of pinnipeds. Human corynosomiasis has been reported as an infrequent foodborne disease in Hokkaido, the northernmost island of Japan. Potential sources of the human infection are marine fish, because they are paratenic hosts of these parasites. In this study, the prevalence and intensity of larval Corynosoma in commercial fish from 17 fishing ports of Hokkaido were examined from April 2016 to January 2019. Out of a total of 1217 fish examined, 122 (10.0%) were infected with cystacanth larvae. The infected fish assemblage was composed of 7 families and 13 species from all the coastal seas of Hokkaido (the Pacific Ocean, Okhotsk Sea, and Japan Sea), showing that commercial fish can be source of human infection when eaten raw. Flatfish of the family Pleuronectidae showed the highest intensity of cystacanths, ranging from 1 to 56. A DNA barcoding system was developed in this study, based on the standard mitochondrial cox1 sequences of morphologically identified adults of Corynosoma spp. from pinnipeds in Hokkaido. By using the DNA barcoding, most of the fish-derived cystacanths were identified as either C. strumosum or C. villosum, and furthermore, a clinical isolate from human as C. villosum. Both of the species were commonly detected from various fish of Hokkaido, irrespective of the coastal seas. Flatfish frequently harbored C. villosum. Considering the wide range of commercial fish in Hokkaido and the advanced transportation system of fresh fish, there is a possibility that human corynosomiasis will occur everywhere in Japan.

24 healthy volunteers will be immunized with three times 50 L3 larvae or placebo followed by treatment with albendazol and subsequently challenged with twice 50 L3 larvae.
Twenty-four healthy hookworm-naive volunteers will be exposed to 50 L3 Necator americanus larvae for a maximum of three times.
Four healthy hookworm-naive volunteers will be exposed to 50 L3 Necator americanus larvae once and will retain infection for up to 2 years.
Anisakidae frequently infect fish species that are commonly eaten by humans. Some of them are recognized as zoonotic agents, and have a high impact on human health. Infestation results fr...

Infection of animals, including fish and man, with a developmental stage of Diphyllobothrium. This stage has recently been referred to as a plerocercoid but the name sparganum has persisted. Therefore, infection of fish or other animals with the plerocercoid larvae is sparganosis. Fish-eating mammals, including man, are the final hosts.
Infection with roundworms of the genus ANISAKIS. Human infection results from the consumption of fish harboring roundworm larvae. The worms may cause acute NAUSEA; VOMITING; or penetrate into the wall of the DIGESTIVE TRACT where they give rise to EOSINOPHILIC GRANULOMA in the STOMACH; INTESTINES; or the OMENTUM.
A genus of parasitic nematodes that occurs in mammals including man. Infection in humans is either by larvae penetrating the skin or by ingestion of uncooked fish.
A genus of nematodes of the superfamily ASCARIDOIDEA. Its organisms are found in the stomachs of marine animals and birds. Human infection occurs by ingestion of raw fish that contain larvae.
A genus of tapeworm containing several species which occurs in the intestine of fish, birds, and mammals including man. Infection in humans is usually by eating uncooked fish. The larval stage is known as SPARGANUM.
